A6151
Shaft Vibration Monitor
Input external disable ES
z22
−
for disabling the limit value alarms; e.g. for service work etc.
Disable function
Input LOW = disable the channel monitoring and limit
value formation
Release
Input HIGH or not switched = enable of channel
monitoring and limit value formation
Signal level
LOW: 0 ... +3 V, HIGH: +13 ... +48 V
1.6.3 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
By setting parameters, depending on the configuration for measurement operation, character-
istic value formation, range etc.
Setting condition
Limit value ALERT < limit value DANGER
Setting range
0 ... 100
%
of the measuring range parameters
Resolution and reproducibility
1 % based on the measuring range end value
Hysteresis
Configurable, 0 ... 20 % based on the measuring range
end value
The hysteresis is only effective with decreasing
current value
Alarm delay
Can be configured to 0 (off), 1,2,3,4,5 sec.; effective on the alarm outputs.
Alarm blocking
Blocking
If (C&P active = yes)
OR
(Voltage or watchdog not OK)
OR
(Ext. disable = disable)
OR
(Channel status = error and limit value
suppression on*)
OR
(Channel status = release delayed)
AND
Channel monitoring effect = yes
No blocking
If the above condition is not satisfied
* In the configuration it is specified whether the alarm outputs will be blocked by channel
monitoring.
