RES-403
Version 1
In addition to the functions shown in the diagram above, various controller operating states are indicated by the
LEDs. These states are described in detail in the table below:
6.2
Temperature setting (set point selection)
The heatsealing temperature is set by means of a 2k
Ω
potentiometer at terminals 16+17. The connecting wires
between the controller and the potentiometer must be shielded (
section 5.6 "Wiring diagram (Standard)" on
Setting range:
0
Ω
0°C
2k
Ω
300°C (PD-3) or 500°C (PD-5)
(depending on the controller configuration).
The relationship between the potentiometer setting and the SET temperature is linear.
The terminals 16+17 are not potenial-free and might have the potential of the secondary voltage of
the impulse transformer.
