Supply
Power supply (see technical data)
0 V (GND) connection.
Analogue signals
GND
10 V Referenzspannungsausgang
Demand value (W), signal range 0... 10 V or 4... 20 mA, scalable
Actual value (X), signal range 0... 10 V or 4... 20 mA, scalable
Output control signal to the valve. Signal range +/- 10V, 0... 10V or 4... 20mA. Sig-
nal type and polarity are set with the parameter SIGNAL:U.
Digital inputs and outputs
Enable input:
General enabling of the application.
START (RUN) input:
Activates the controler and sets control signal.
S0 input:
Switching over between the parameter sets.
S0 = OFF : parameter set 1 is active
S0 = ON : parameter set 2 is active
RAMP/INTEG input:
Activates the ramp- or the integrator function. Function is chosen with the
parameter PIN5.
READY output:
ON: The module is enabled; there are no known errors.
OFF: Enable (PIN 8) is disabled or an error (current input or internal error) has
been detected.
STATUS output:
Monitoring of the control deviation depending on the CDWIN parameter, the status
output will be deactivated, if the control deviation is higher than the adjusted per-
mitted range.
ON: control deviation is within the permitted range.
OFF: control deviation is out of the permitted range.
