Heavy duty monitoring equipment for the bulk handling and processing industries
Founded in 1983 Rotech systems manufacture and supply worldwide, high quality, high reliability equipment for monitoring and measuring the speed, position and direction of rotating shafts Rotech Systems are the worlds leading manufacturer of high quality monitoring solution products with an unparalleled reputation for reliability, durability and quality. Major features are tough, strong, heavy duty construction, designed to operate and give years of maintenance free operation in even the harshest industrial environments, quarries, mines, etc. And simple, quick, installation. Main applications are in the bulk handling and processing industries. Protecting conveyors, elevators, screws, crushers, mixers, etc. Anywhere where slowing down or stoppage will cause product spillage, blockage, etc. and incur downtime, lost production, cleaning up, spoilt product, etc. Equipment Can Give Visual And/Or Audible Alarms Plus Shutdown Items Of Plant For A Speed Reduction Of Only 5% (Adjustable 5% To 90%) Protects Against Conveyor Belt Slip, V Belt Slip, Chain Breakage, Mechanical Failure, Stoppage, Blocking, Jamming, Etc. Industries using Rotech: food, textiles, glass, grain, power generators, fertiliser, sand, gravel, roadstone, coal, steel, ore.
Introduction Wherever materials are transported or processed by conveyors, elevators, screws, gushers, mixers, etc, there are applications for “Rotech�. Heavy duty shaft encoders. Food, Grain, Pharmaceuticals, Chemicals, Sand, Stone, Cement, Ore, Coal, Ash, In Factories, Quarries, Mines, Power Utilities, And Dock Installations Are All Excellent Examples. A single conveyor may run for long periods without any problems, but not forever, the day arrives when it starts to slip or slow down and unless action is taken quickly to switch off the conveyor, crusher or plant that feeds it then a major spillage can occur. In a large plant with many conveyors and drives the potential for problems is multiplied by every additional drive element.
1
The costs of clearing up a spillage are not simply the costs of a man with a shovel, this is the tip of the iceberg, they can include: Damaged belts (Conveyor & Drive, “V”, Flat, Etc.). Damaged plant & machinery. Mechanical diggers, front loaders, etc. To clear up grain, sand, stone, ore, coal, etc. Contamination to food, pharmaceutical, chemical, products, resulting in rejection and waste. Whilst these costs can be considerable, they can be minor compared to the real cost. The REAL COST is the loss in Production, Throughput and Revenue whilst cleaning up. Hundreds, even thousands of dollars can be lost for every hour a plant us not producing product. “Rotech heavy duty shaft sensors provide simple, low cost, high reliability protection against these problems.
General Description The “Rotech” range of shaft monitoring equipment is comprised of a range of heavy duty motion sensors and associated speed relays. The heavy duty shaft sensor is installed on the end of the shaft being monitored and sends and electrical signal proportional to the speed of the shaft to a suitable control unit. The control unit can be a “Rotech” speed relay, a programmable controller, a computer, data logger device or other proprietary control equipment. The alarm level of the control unit is set to just below the normal running speed of the shaft. In the event of the shaft slowing below the set level, the control unit operates and can be connected to give an alarm to the operator and/or shutdown preceding items of plant.
Advantages of ‘Rotech ‘Rotech’ heavy duty motion sensors and encoders combine many unique design features to give the customer:•Simple installation •High performance •High reliability •Price benefits
2
Installation One hole drilled and tapped into the end of the shaft to be monitored, gives simple, uncomplicated, fast installation. One type of unit covers all types of drives, conveyors, elevators, crushers, etc. Allowing standardisation of designs, installation and spares. No target discs to design, manufacture and install. No sensor brackets to design, manufacture and install. No guards to design, manufacture and install. No on – plant adjustment or setting up required. The ‘rotech’ unit is carried on the shaft and moves with it, it is unaffected by shaft end float, belt adjustment, etc.
Performance ‘Rotech’ motion sensors/encoders are digital pulse generators guaranteed accurate to within 0.5%, they cannot drift and require no checks or periodic calibration. With pulse output rates from 1 pulse per rev to 360 pulses per rev, drive speeds from 5000 rpm down to 0.03 rpm (2 revs/hour) can be accurately and reliability measured and monitored.
Reliability “Rotech” units are designed to operate and survive in even the toughest industrial environments, they have been particularly developed for the quarrying and mining industries, however their compact size makes them just as suitable for light industries. Heavy duty castings, heavy duty sealed bearings and robust fully encapsulated industrialised electronics form the tough strong core of these units. Extensive use is made of modern engineering adhesives and sealants to double up on the traditional precision assembly methods and ensure even greater reliability. ‘O’ Ring seals on end covers, grease chambers, spring loaded shaft seals and liquid tight flexible conduit and glands complete these units to give outstanding levels of protection and ensure the highest levels of reliability and operational life. All Rotech units are totally maintenance free – sealed for life!
Price Installed price is competitive or possibly lower than alternative methods, ultimate in operational life and reliability is an added bonus.
3
Applications The principle application for “Rotech” heavy duty motion sensor is as a speed or slow down switch on plant and machinery. They can be fitted to conveyor belts, elevators, conveyor screws, crushers, mixers, valves and any other plant that presents a hazard if it slows beneath its normal running speed. They should always be installed at the end of the drive system. On a conveyor and elevator they should be installed on the tail drum, tail roller, snub roller, gravity take up roller or any roller that is driven by the conveyor belt itself. Any slowing down of the drive motor, gearbox, drive chains, drive belts, or the conveyor belt slipping, etc, will result in the conveyor belt and the selected drum/roller slowing down which will be detected by the encoder. All elements of the conveyor are therefore monitored. The heavy duty shaft sensor should, unless special circumstances apply, never be fitted to the drive roller or drum. On conveyor screws the heavy duty shaft sensor should be installed to the non-driven end of the screen.
Other Applications Shaft sensors can give information on the speed, angular position, direction and number of revolutions completed by a rotating shaft. Via racks, screws, slides, etc all of these functions can be translated into linear functions. Although its use as a speed switch is the principle application of “Rotech” heavy duty shaft sensors, they also fulfil a wide range of other applications in many types of industries.

Installation – Mechanical - (If the shaft end cannot be drilled please refer to Magcon fixing shown below) 1. 2. 3.
Select a suitable shaft to install the ‘Rotech’ unit to. Use a 5mm drill to drill a pilot hole to a depth of 25mm into the centre of the end of the shaft. Use a 10mm drill to open the hole to the required tapping size.
IMPORTANT Take care that the shaft is drilled centrally. 4. 5. 6.
Tap the 10mm X 25mm deep hole 12mm x 1-5. Remove the rear cover the Motion Sensor/Encoder and using a 10mm Allen key wrench install the unit onto the shaft. Re-fit the rear cover. Bolt the flexible securing strap to any convenient part of the machine frame work

Installation – Electrical refer to page 6 for typical installation commissioning and testing information
1.
Always complete the mechanical installation before commencing the electrical installation.
2.
Install a suitable junction box within 300 – 600mm of the Motion Sensor/Encoder.
3.
Gland – Off the flexible conduit of the Motion Sensor/Encoder in the junction box and connect the 2 or 3 wires to suitable terminals. (The flexible conduit and cable are supplied over-length they can be cut back and shortened as required)
4.
Connect suitable wires and cable to route the Shaft Encoder signal back to the control panel.
Important The maximum distance recommended between the Motion Sensor/Encoder and the control panel is 1000 yards. Armoured or screened cable should be used id the cable is routed in the vicinity of power cables. Do not route the Motion Sensor/Encoder signal through multi-core cables carrying other signals or voltages. 5. Alternative Installation An alternative method of installation is to house the Control Module/Speed Relay etc. in a slightly larger terminal box. A mains signal (typically 110Vac) can then be switched on by the control module and then routed via multi-cores; unprotected cables etc. back to the control panel.
Electrical Connection Options Refer to page 11 for details of Rotech motion sensors and encoders electrical output options available.

Other Applications Motion Sensors/Encoders are used extensively in many different industries for a wide variety of applications. Besides measuring the speed of a rotating shaft, they can determine direction of rotation, angular position, and the number of revolutions or parts of revolutions completed. Using screws, slides, racks & pinions these angular functions can be translated into linear or length functions. The following are the more popular applications that ‘Rotech’ Heavy Duty Motion Sensors/Encoders are utilised for.
Speed Indication Used in conjunction with a Digital Panel Meter to display RPM or linear speed of a Conveyor Belt.
Length Measurement Used in conjunction with a Counter unit and either a roller or wheel of known circumference, to measure cut-off lengths, total throughput, or to position material for a process operation.
Direction Indication Using a ‘Rotech’ Heavy Duty Motion Sensor/Encoder with dual quadrature outputs, direction of rotation can be determined. This is most frequently used to detect if a heavily loaded conveyor starts to run backwards.

VS 4000 Series Screen Vibration Sensor Application Information
From a pilot introduction starting in 2000, Rotech Systems now have over 200 VS 4000 Vibration Protection Systems in operation. Most modern screens are designed with the benefit of computer simulation and can therefore cope with a wide range of operational conditions. Variations in feed rates and composition of the material being fed to a screen (wet, sticky, etc.) can however in some circumstances result in an excessive amount of material being on the screen. If as a result, the rate and speed of vibration of the screen slows down, even temporarily, problems can occur very quickly. Material continues to be fed to the screen at the normal rate but the slowdown causes the discharge rate to be reduced, a marginal overload can quickly enter a runaway situation with the material arriving at the screen causing an every increasing overload and further slowdown, the discharge rate is then further reduced and the overload increases exponentially. Mechanical Failure – “V” Belt damage or the intervention of the screen drive motors electrical overload is often the first thing the operator will know that all is not well! Overloaded screens and feeders, V belt damage, spillage, cleaning up, etc. and their associated downtime and lost production can now be a thing of the past. Key elements in the design brief were:Quarry environment construction to ensure long term reliability, easy installation and simple setting up. A ‘Rotech’ vibration sensor, fitted to screen, monitors its rate of vibration and will operate an alarm or switch the in – feed conveyor off if the screen slows down. Accuracy is such that even a drop in speed of 5% for a few milli – seconds can be detected and action taken almost instantaneously. On V – belt driven screens, the screen drive motor can be switched off the instant any slippage occurs, preventing costly damage to belts. The VS 4000 Vibration sensor is housed in heavy duty aluminium housing with all internal components and cable connections fully encapsulated. It is supplied complete with a heavy duty galvanised angle bracket that is simply bolted or welded to the side of the screen or feeder. A heavy liquid tight flexible conduit is then looped to a convenient electrical junction box and the signal routed by standard PVCSWA cable back to the main control panel. The associated SR 4000 Speed Relay Control Module has a single dial that is turned to locate the actual running speed of the screen / feeder and then set to just below this speed. Typically on a screen / feeder vibrating at 750 throws per minute the speed relay is set to 725, if the speed drops below this level the SR 4000 speed relay operates in less than 10 milli – second.

Product Descriptions Speed Relays Rotech Type AUE400 & SR4000 Rotech offers 2 types of speed relay modules, in the form of:Type AUE 400 Speed Relay – Advanced Series This unit includes as standard: • Dual AC Supply 110/240VAC 50/60Hz • Single output relay S.P.C.O. – Volt free Contacts • 3 Selectable Speed Ranges – Factory Settings – 0 to 10, 100 & 1000 RPM • Selectable Start Delay – Factory Setting = 10 seconds • Input signal repeat output – open collector transistor
Type SR 4000 Speed Relay – Standard Series This unit includes as standard: • Dual AC Supply 110/240VAC 50/60Hz • Single output relay S.P.C.O. – Volt free Contacts • 3 Selectable Speed Ranges – Factory Settings – 0 to 10, 100 & 1000 RPM Variations to Factory Settings All Speed Relays can be calibrated to suit Rotech Motion Sensors from 1 to 1000 pulses per revolution dependant upon the sensor type it is being used with. e.g.. 401, 410, 416, 4120, 4360, 41000 etc. The part number can be occasionally suffixed with either ‘E’ or ‘W’ to indicate it is for use with a type E or type W motion sensor output e.g. AUE 404W, SR4010E etc. The part number can also be suffixed with x2, x5, x10 (multiply by) etc. This indicates the unit has been calibrated for a higher than standard speed ranges. This affects the ‘speed ranges’ information in the above description. Thus x2 would change ranges to; 0 to 20, 0 to 200, 0 to 2000 RPM. x5 would change ranges to; 0 to 50, 0 to 500, 0 to 5000 RPM. x10 would change ranges to; 0 to 100, 0 to 1000, 0 to 10,000 RPM. Similarly units can be calibrated for lower than standard speed ranges. Here the part number is suffixed by /5, /10, /100 (divide by) etc. e.g. AUE 4360/100, SR4020/10 etc. Suffix /5 would change the ranges to; 0.2 to 2, 2 to 20, 20 to 200 RPM. Suffix /10 would change the ranges to; 0.1 to 1, 1 to 10, 10 to 100 RPM. Suffix /100 would change the ranges to; 0.01 to 0.1, 0.1 to 1, 1 to 10 RPM. Standard supply voltages is 110/240VAC 50/60 Hz while 12V, 24VDC, 24VAC can be provided upon application.

SR 4000 Speed Relay
The following option can be included to any SR 4000 type unit. please refer to ‘Rotech systems’ for details The automatic start delay on the SR 4000 speed relays operates as follows: As soon as the main drive is started and the Rotech Motion Sensor/Encoder starts to rotate the start delay is initiated. The start delay energises the SR 4000 speed relay for a period of 20 seconds. During this period the drive should reach its normal operating speed and the speed relay will then remain energised. If the drive does not reach its normal running speed by the end of the 20 seconds the speed relay will de-energise and the drive will shut down. The 20 second start delay will only re-operate if the speed of the drive drops below 1 RPM and remains below 1 RPM for a period of 20 seconds.

SR 4000 Speed Relay
Commissioning and testing must only be carried out by a qualified and competent technician who is fully familiar with the plant to which the “Rotech” equipment is installed. 1.The SR 4000 Speed Relay monitors the speed of a drive and gives a signal if the speed of the drive falls below or rises above its normal running speed, the output relay of the SR 4000 can be connected to give a variety of control functions. 1.1 The output relay can be connected to sound an alarm, bring on a warning light, etc 1.2 Can be connected into the motor control circuit to switch off / trip out the drive motor. 1.3 It can be connected into the motor control circuit of a conveyor, machine, etc, proceeding the drive to which it is fitted, to stop the delivery of material, etc to the drive that has slowed down or stopped. 1.4 With the use of additional control relays and / or timers the above functions can be combined, plus many others created. 2. Use of the automatic start up delay is optional, this feature is normally only required when the SR 4000 is connected as in 1.2 above and the time taken to reach normal, running speed is several seconds longer. SETTING UP 1. Check that all connections are correct and any links fitted to select the running speed range. 2. Turn the potentiometer on the SR 4000 Speed Relay fully anti – clockwise. 3. Start the drive. 4. “Supply On” and “Relay On” indicators should be illuminated and “Input” indicator should be pulsing or partly illuminated. 5. Turn the potentiometer slowly clockwise until the “Relay On” indicator extinguishes. 6. Now turn potentiometer anti – clockwise until “Relay On” indicator just illuminates. 7.The SR 4000 Speed Relay is now set to de- energise if the speed of the drive decreases below that set on the potentiometer. 8. If the drive is subject to temporary short period decreases in speed that you wish to ignore, the potentiometer can be turned further anti- clockwise to say 80% or 70% etc, of normal speed, the SR 4000 Speed Relay will then only de – energise if the speed of the drive falls below this setting. 9.Test by starting and stopping the drive, when running normally “Relay On” indicator will be illuminated, observe that when the stop button is pressed, as soon as the drive speed decreases below that set on the potentiometer, the “Relay On” indicator extinguishes.

IMPORTANT- All connections and dis-connections must be made with mains power supply switched off.
2. Under normal running conditions “Supply On” and “Relay On” indicators should be illuminated. 3. “Input” indicator should be observed to pulse on and off when the drive is running slowly. At higher speeds on/off pulses become blurred and indicator is illuminated but not at full brightness. When fitted to higher speed drives the input can be tested by stopping drive and observing that at final few rpm before stopping “Input” indicator pulses on and off. When stopped “Input” indicator can be in either on or off condition. If no input signal is observed, check connections to shaft encoder are correct, if input signal is still not observed proceed to 6. 4. If input signal is present but the SR 4000 cannot be set up correctly then proceed as follows:4.1 Turn potentiometer fully clockwise, if “Relay On “ indicator does not extinguish, then the speed range selected is to low, change speed range links on terminals to select a higher range. 4.2 Turn potentiometer fully anti-clockwise, if “Relay On” indicator is not illuminated then speed range selected is to high, change speed range links on terminals to select a lower range. 5. “Relay On” indicator extinguishes but does not stop drive motor, check correct connections have been made to SR 4000 relay terminals (no contacts 4 & 5) and that all external connections to motor control circuit are correct. 6. Testing the SR 4000 Speed Relay 6.1 NON– W Types (DC Sensors) Only Disconnect shaft encoder connections to terminals 7, 8 & 9 Disconnect any speed range links to terminals 10, 11 & 12 Connect a small switch or push button between terminals 8 & 9 Simulate input pulses by switching on and off “Input” indicator should illuminate / extinguish and “Relay on“ indicator should illuminate. Set switch to off position, “Relay On” indicator should extinguish (on low speed units this may take several seconds) 6.2 “W” Types (AC Sensors) Disconnect shaft encoder connections to terminals 1 or 2 & 3 Disconnect any speed range links to terminals 10,11 & 12 Connect a small, insulated switch or push button between terminals 2 & 3 Simulate input pulses by switching on and off “Input” indicator should illuminate / extinguish and “Relay On” indicator should illuminate Set switch to off position, “Relay On” indicator should extinguish (on low speeds this may take several seconds) 7. Satisfactory completion of the above tests indicates that the SR 4000 Speed Relay is operating correctly If when the shaft encoder is re connected the system is still not operational, then the problem is either with the installation cables or the shaft encoder See shaft encoder installation data sheet for information on testing shaft encoders.

The AUE 400 monitors the speed of a drive and gives a signal if the speed of the drive falls below or rises above its normal running speed. The output relay of the AUE 400 can be connected to give a variety of control functions. i. The output relay can be connected to sound an alarm, bring on a warning light, etc. ii. It can be connected into the motor control circuit to switch off/trip out the drive motor. iii. It can be connected into the motor control circuit of a conveyor, machine, etc. preceding the drive to which it is fitted, to stop the delivery of material, etc. to the drive that has slowed down or stopped. iv. With the use of additional control relays and / or timers the above functions can be combined, plus many others created. 2. Use of the 10 second start up delay is optional. This feature is normally only required when the AUE 400 is connected as in 1.2 above and the time taken to reach normal running speed is several seconds or longer. 3. The repeat output facility allows the input pulses from the motion sensor/ encoder to be re-transmitted to other equipment. Typical applications are speed indication, secondary input to plc, computer, etc. Analogue conversion 0 to 10VDC/4 to 20MA, etc. or connecting two or more AUE 400 modules to a single motion sensor/ encoder to obtain multiple alarm/trip levels. SETTING UP 1. Check that all connections are correct and that links are fitted to select the correct speed range. 2. Turn the potentiometer on the AUE 400 speed relay fully anti-clockwise. 3. Start the drive and if the run-up delay facility is being used, wait 10 seconds until the “delay on” indicator is extinguished. 4. “Supply on” and “relay on” indicators should be illuminated and “input” indicator should be pulsing or partly illuminated. 5. Turn the potentiometer slowly clockwise until the “relay on” indicator extinguishes and note setting. 6. Turn potentiometer anti-clockwise until ‘relay on’ indicator illuminates, then turn clockwise and set to approximately 90% of the above setting. 7. The AUE 400 speed relay is now set to de-energise if the speed of the drive decreases below that set on the potentiometer. 8. If the drive is subject to temporary short period decreases in speed that you wish to ignore, the potentiometer can be set to 80%, 70%, etc. of normal running speed, the AUE 400 speed relay will then only de-energise if the speed of the drive falls below this setting. 9. Test by starting and stopping drive. When running normally "relay on" indicator will be illuminated. Observe that when the stop button is pressed, as soon as the drive speed decreases below that set on the potentiometer, the “relay on” indicator extinguishes.
