5.4. Analog signals
5.4.1. Analog input Ch1
0 to 10 V analog input.
Analog control Configuration parameter set to Off: Used to monitor a proportional air
regulator valve output or other sensor for force control and monitoring. Scaling is set in
Force calibration.
Analog control Configuration parameter set to On: Used as the current control input (see
configuration section).
5.4.2. Analog output
0 to 10 V analog output.
Analog Out Configuration parameter set to Force: Outputs the force control signal to
drive a proportional air regulator valve. Scaling is set in Force calibration.
Analog Out Configuration parameter set to Current: Outputs a signal representing the
measured current. Scaling must be set in the Waveform 10V= configuration parameter.
5.4.3. Analog input Ch2
0 to 10 V analog input.
5.4.4. Toroid
Spot welds only. A toroid (Rogowski coil) may be used for measuring the current (normally
on the secondary side of the power transformer). Sensitivity may be set in current
calibration (see Current calibration section).
If the Toroid test configuration parameter is set to On, then the resistance must be in the
range 10 to 300 Ohms.
