1.7.3 Limit value formation and alarms

Two alarm channels, each with an alarm output ALERT and DANGER, and separate limit value
adjustment. Alarming if the characteristic value exceeds the limit value parameters. (Current
value > limit value)
Setting the limit value
Through setting parameters, depending on the configuration for measurement operation,
characteristic value formation, range etc.
Setting condition
Setting range
Resolution and reproducibility
Hysteresis
Alarm delay
Can be configured to 0 (off) ... 25 sec.; effective on the alarm outputs.
Alarm blocking
Blocking
No blocking
* In the configuration it is specified whether the alarm outputs will be blocked through channel
monitoring.
Input LOW = disable the channel monitoring and limit
value formation
Input HIGH or not switched = enable of channel
monitoring and limit value formation
LOW: 0 ... +3 V, HIGH: +13 ... +48 V
Limit value ALERT < limit value DANGER
0 ... 100 of the measuring range parameters
%
1 % of f.s.d
Configurable, 0 ... 25 % based on the measuring range
end value
The hysteresis is only effective with decreasing
current value.
If (C&P active = yes)
(Voltage or watchdog not OK)
(Ext. disable = disable)
(Channel status = error and limit value
suppression on*)
(Channel status = release delayed)
Channel monitoring effect = yes
If the above condition is not satisfied
