Entering Process Set Value and Parameters

Setting the process value: When the $ or - button is pressed the device displays the process set value (1) and the SET LED (1) flashes. Adjust the required process set value with ! and ! buttons. Press the ! or 0 button to save the new process set value to memory. Pressing the $ or -button instead exits the setting mode without saving the new value to memory. For models with two outputs, pressing the 0button will start the SET 2 LED flashing. Use the UP and DOWN arrows to set the desired value and press 0 again to save this new value and to stop the LED flashing.

Observing and changing parameter values: Hold down the $ or -button until the HS1 parameter appears. To enter this parameter, press the ! button. Adjust the value using the ! and ! buttons. Save this setting by using the ! or 0button. This will also bring up the next parameter. For models with two outputs, the HS2 parameter is displayed. Repeat until all the parameters for the process have been adjusted.

Parameters

This is the desired temperature setting for the SET1 process to be controlled. Control of the output relay

SET 2

is in accordance with this value. In models with two outputs, SET 2 controls output 2.

The Hysteresis value for the output can be adjusted from 0.0 to 10.0 for PT-100 ( -19.9 to +99.9 )°C and from 0 to 100 for PT-100 (0 to 400)°C, J (0 to 800)°C and K (0 to 999)°C type thermocouples. The Hysteresis is the dead band. eg. If the SV is 100°C and the HYS is 10, the output will be deenergized once the process value (PV) is equal to the set value (SV) and will not reenergize until the PV falls below 90°C. HS2 only appears in models with two outputs.

The controller can be set for heating or cooling. If this parameter is 000, the output is normally energized and is set for the HEATING mode. It can operate in the COOLING mode when this parameter is set to 001 in which case the output is normally deenergized. rL2 only appears in models with two outputs. It can be set the same as or differently from rL1.

This parameter can be used to artificially alter the present value displayed. It has no effect on the control system. This is useful when a liquid is used to heat another liquid, for example, in which case the difference in temperature can be ignored and the display made to read a value which better suits the user’s purpose without affecting the process value. It can be adjusted from -10.0 to 10.0 for PT-100 ( -19.9 to +99.9 )°C , from -100 to 100 for PT-100 (0 to; 400)°C , J (0 to 800)°C and K (0 to 999)°C type thermocouples.

Use this parameter to determine the output’s minimum off time. When the output becomes inactive, the time set here must expire before the output is reactivated. It can be adjusted from 0 to 100 seconds.

E If there is no operation for 20 seconds, the device returns automatically to the operation screen.

Changing and Saving Set Values

Control Algorithm

Operation Screen When SET button is pressed, SET LED illuminates and the SET value is observed on the display.

OUT1

PROG

SET SET

The ON/OFF control algorithm attempts to maintain the process temperature value equal to the desired set value by energizing and deenergizing the output relay which turns the control element (usually a magnetic contactor) on and off. Each process is unique in that some are less susceptible to wider fluctuations in temperature than others. Set the hysteresis to reflect this. Increasing the hysteresis will reduce the number of on/off cycles thus prolonging the life of these components. However, too much hysteresis can adversely affect the material being processed. Special attention should be taken during setup to strike the balance between maximizing the life of the components and process quality.
