Measurement pause:
With a high signal at the Reset input (26) in the Off state, the PIREG

-545
stops the resistance measurement making it possible to interrupt the heat seal band circuit without
generating an alarm. (from V1.00/1.07/1.29/1.23)
5.8.5. “Set” Temperature Input
:
It is possible to program the “Set” temperature (heat sealing temperature) on the PIREG
®
-545 three different
ways:
Internal:
The “Set” temperature can be programmed from the PIREG
®
-545’s Settings menu 101.
With 0–10VDC:
The “Set” temperature can be programmed by applying a 0–10VDC voltage to the
analog input at terminals 23 and 20. The applied voltage is linear to the programmed temperature
range set in Configuration menu 206. I.e., 10V corresponds to 300°C, if the selected temperature
range is 300°C. And 10V corresponds to 500°C, if the selected temperature range is 500°C.
With Potentiometer:
The temperature set value is set by a potentiometer. In the case of the po-
tentiometer, the cutter is linked to the set-value input (23), the CW connection to the actual value
output (24) and the CCW connection to the GND connection (20). In this setting, the Actual Value
Output must be programmed in Configuration menu 216 to operate as a “10V reference” voltage
source with an output voltage of 10V. Pay attention to the direction of rotation when connecting
the potentiometer. In the case of clockwise rotation on the potentiometer, the voltage should in-
crease at the set value input. The chosen temperature range is imaged to the set value voltage, as
described above.
