Operating

Instructions

RESISTRON/CIRUS temperature controllers are
available in several different variants. Some of these
controllers allow the set point to be selected by means
of an externally connected potentiometer.
ROPEX offers PD-3 (300 °C range) and PD-5 (500 °C
range) precision potentiometers, which are optimally
tuned to the controllers, for this purpose.
These potentiometers permit the SET temperature to
be adjusted exactly with the help of the digital display in
the window of the fine control knob. The number that

appears on the display corresponds to the SET
temperature in °C.
The PD-3 (or PD-5) precision potentiometer consists of
a P-3 (or P-5) setting potentiometer and a KD fine
control knob with digital display.

The information provided in the latest

!

version of the controller documentation shall
be heeded when using the PD-3 or PD-5
potentiometer, in order to avoid malfunctions.
