Description of the parameter settings:
SETPOINT E1
Failure behaviour is initiated if setpoint E1 or actual value E2 fail or in case
of loss of the bus communication.
The monitoring depends on the preset setpoint range, e.g.:
E1 = 4 – 20 mA, E1 lower than 3.7 mA = loss of signal
E1 = 10 – 20 mA, E1 lower than 9.7 mA = loss of signal
Monitoring of E1 = 0 – 20 mA is not possible
E1 OR E2 FEEDBACK
.
Failure behaviour is initiated if setpoint E1 or feedback E2 fail.
.
The following is monitored:
for actuators with potentiometer: Cable break is detected
.
for electronic position transmitter RWG 4 – 20 mA in actuator:
E2 lower than 3.7 mA = signal loss
for MWG in actuator:
Communication faults and MWG internal faults are recognised
E1, E2 OR E4 FEEDBACK
Failure behaviour is initiated if setpoint E1, feedback E2, or actual process
variable E4 fail
BUS INTERFACE
A failure behaviour is initiated in case of loss of bus communication
