Installation
♦ Install control in safe operating area.
♦ Plug Heater/Cooler into the output connector, located on the back of the control.
♦ Connect input sensor into the proper connection input on control and place the thermocouple in the process that is being controlled. Install ferrite on lead wire of sensor. If further instruction is needed, see the user manual on installation of the ferrite.
♦ Plug supplied AC cord into the IEC connector, located on back of the control.
Operation Set up
♦ To enter the user-configurable setup press the MENU key from the system status screen.
♦ Use the MENU key to advance through each menu setting.
♦ Use the UP & DOWN key to make changes in each menu setting screen.
♦ Reference the flow chart (see pages 16 & 17 of manual) to have visual of the overall menu layout.
♦ When all settings have been made and saved the control will return to the System Status screen.
♦ Set the Set Point temperature by pressing the select button one time. A line will appear under the Set Point value.
♦ Use the UP and DOWN arrow keys to change the Set Point value.
♦ Press the SELECT key one time when finished and the line under the Set Point will disappear.
♦ Press the RUN/STOP key when ready to start the heating/cooling operation.
♦ Running the TUNE feature is recommended when running a new process variables.
Tune Operation
♦ Set the process temperature as instructed in the operation setup.
♦ Verify that the Auto Tune feature is enabled in the menu settings.
♦ From the System Status screen set the Set Point temperature.
♦ Press the TUNE button and the indicator showing Tune will have be illuminated on display.
♦ The Set Point value isn’t changeable after the Tune process has started. The value is locked until the Tune process is complete or aborted by the user.
♦ Stopping the Tune operation prior to it finishing will cause the PID settings to be returned to factory default values.
♦ PID values will be saved in non-volatile memory.
Control Sensor
Proper placement of the sensor can eliminate many problems in the operation of the system. The probe should be placed so that it can detect any temperature change with little thermal lag. In a process that requires fairly constant heat output, the probe should be located close to the heater. In processes where heat demand is variable, the probe should be located close to the work area. Experimenting with probe location will provide optimum results for the users specific application.
