For the terminals of the external potentiometer touch voltage protection must be installed.
External grounding is not allowed. If this warning is ignored, the controller will be damaged by frame
currents.
If a ROPEX PD-x precision potentiometer is used, the SET temperature can be adjusted exactly with the help of
the digital display in the window of the dial. The number which appears on the display corresponds to the SET
temperature in °C.
The set point that is selected for the heatsealing temperature must be greater than 40°C. If not, the heatsealing
band will not be heated up when the "START" signal is activated.
If a potentiometer is not connected, the set point is assumed to be zero. When you connect the
potentiometer, please note the direction of rotation!

Temperature indication (actual value output)
The RES-403 supplies an analog 0…10VDC signal, which is proportional to the real ACTUAL temperature, at
terminals 14+15.
Voltage values:
0VDC
0°C
10VDC
300°C (ATR-3) or 500°C (ATR-5)
(depending on the controller configuration)
