RES-402
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:
7.2
Temperature setting (set point selection)
The heatsealing temperature of the RES-402 can be set in two ways:
• By applying a 0…10VDC voltage to the analog input terminals 15 + 12:
The relationship between the applied voltage and the SET temperature is linear.
Setting range:
0VDC
0°C
10VDC
300°C
Please refer to section 7.3 "Temperature indication (actual value output)" on page 22 for a circuit diagram.
