3.9 Parameter group 5: Alarms
NOTE
Active alarms are signaled at the digital output and using the
"Analog feedback" option.
3.9.1 LEAKAGE – Leakage at 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.
3.9.2 SP_RGE – Setpoint monitoring
With this parameter, you can determine that a corresponding
alarm is signaled via the digita l 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.
3.9.3 SENS_RGE – Operating range exceeded
With this parameter you can determine that an alarm is
signaled via the digital output when the con
fi gured operating
range is exceeded by 4%. (Pos ition < -4 % or > 104 %).
This may indicate improperly ad justed mounting or mechanical
wear in a limit stop.
ACTIVE Alarm active.
INACTIVE Alarm not active.
3.9.4 CTRLER – Controller inactive
You can use this parameter to speci fy 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
con
fi guration.
NOTE
For details of which statuses lead to a message, see see
Chapter "Alarm codes" on page 35.
ACTIVE Alarm active.
INACTIVE Alarm not active.
3.9.5 TIME_OUT – Dead band time limit
Use this parameter to activate the "Dead band time limit"
function.
The alarm is issued via digital ou tput when the setpoint within
the speci
fi ed monitoring time is not reached in control mode.
(The monitoring time is entered with parameter group 4,
„TIME_OUT“ .) The function is only active in control modes
ACTUATOR and AUTO_ADJ .
ACTIVE Dead band time limit is activated.
INACTIVE Alarm not active.
3.9.6 STRK_CTR – Movement counter
With this parameter you can determine that an alarm is
signaled when the movement counter exceeds the speci
fi ed
limit value. The limit value is edited remotely via PC.
ACTIVE Alarm for exceeding travel counter limit value
INACTIVE No Alarm
