Operation with potentiometer: Potentiometer activ
The valve setpoint is changeable with a potentiometer. The touch functions are not active.
The center position of the potentiometer always equals 0% (no movement)
i.e.: Middle position corresponds to 12mA at range 4 .. (12) .. 20mA
Center position corresponds to 0V at range (0) .. +10V (left side of adjustmant range not active)
When potentiometer operation is activated, the output setpoint is 0%, independent of the current position.
Only after the potentiometer has been turned to 'zero position' once, the potentiometer is active.
('Range bar' changes from 'Orange' to 'Green')
This applies:
- when power up the test device
- when selecting the operation with potentiometer
- when working with dead man´s handle
Sockets for external measurements: Measuring sockets activ
The setpoint and the actual value of the valve can be recorded (external measuring devices, data loggers).
The measured values are only available at the sockets if this setting is activated.
The sockets are wired internally, according to the range selected (V or mA - no jumper is needed at the meas-
uring sockets).
The measuring sockets can also be used:
- for device calibration
- for controlling a frequency converter or other devices
(in the V range without special adapter cable)
Analog curves: 4 curves activ
It can be selected whether only the setpoint and the actual value are shown in screen 'ANALOG' or
additionally 'Uv' and 'Iv'.
Only devices with potential-free measuring inputs may be connected!
