Parameter group 5: Alarms

Note
Active alarms are signaled at the digital output and using the
"Analog feedback" option.
LEAKAGE – Leakage to actuator
If the monitoring function detects leakage at the actuator, a
message is issued via alarm output on the mainboard.
ACTIVE
Monitoring active.
INACTIVE Monitoring inactive.
SP_RGE – set point monitoring
With this parameter, you can determine that a corresponding
alarm is signaled via the digital output when falling below or
exceeding the setpoint range (<3.8 mA or above 20.5 mA).
ACTIVE
Setpoint monitoring active.
INACTIVE
Setpoint monitoring inactive.
SENS_RGE – operating range up-scaled
With this parameter you can determine that an alarm is signaled
via the digital output when the configured operating range is
exceeded by 4%. (Position < −4 % or > 104 %).
This may indicate improperly adjusted mounting or mechanical
wear in a limit stop.
ACTIVE Alarm active.
INACTIVE
Alarm not active.
CTRLER – controller inactive
You can use this parameter to specify signaling of an alarm via a
digital output if the positioner is not active, i.e., if the control
mode is interrupted by another operating mode or by
configuration.
Note
For details of which statuses lead to a message, see see Chapter
Alarm codes on page 42.
ACTIVE
Alarm active.
INACTIVE
Alarm not active.
