Temperature setting (setpoint specification)
The welding temperature can be set in the RES-5007 in two ways:
• Through application of a voltage 0…10 VDC at the terminal analogue input 16 + 13:
The correlation between the applied voltage and the ACTUAL temperature is linear.
Setting range:
0 VDC
0 °C
10VDC
300 °C or 500 °C, Depending on the device configuration
A corresponding diagram is depicted in section 8.3 "Temperature display (actual value output)" on page 20.
• Through connection of a 2 kOhm potentiometer at the terminals 13…16:
To be able to specify the setpoint with a potentiometer, the controller provides a reference voltage of +10 VDC
(
±
5%
)
at terminal 15.
The correlation between potentiometer setting and the SETPOINT temperature is linear.
The connection line between controller and potentiometer must be screened.
When the ROPEX precision potentiometer PD-x (PD-03 for 300 °C or PD-05 for 500 °C) is used, the set SET-
POINT temperature can be set exactly with the help of the numbers in the viewing window of the fine drive button.
The set number equals the SETPOINT temperature in °C.
The setpoint specification for the welding temperature must be greater than 40 °C. If it is less, no heating process
takes place when the START signal is activated.
Setpoint value zero applies if the potentiometer is not connected or 0 VDC is applied at the setpoint
value input. Pay attention to the direction of rotation when connecting the potentiometer!
