West Control Solutions CI 45 - Manual (Page 32)

g
With measurement value or signal change with latch selected ( ConF / Lim / Fnc.x = 2, 4),
the alarm relay remains set, until the alarm was reset in the error list, via di1 or via the
interface (
Lim1 ... Lim3 = 1).
For this, reset value 0 must be specified in the error list or via the interface.
g
After power on or an engineering download an used input filter has an effect on the gradient of the input
signal. Therefore a valid alarm monitoring can only be processed after a certain rise up time. This time
depends on the value of the filter time constant t.F.
For t.F = 0 the monitoring results are valid immediately.
6.14.2 Monitoring the number of operating hours and switching cycles
Operating hours
The number of operating hours can be monitored. When reaching or exceeding the adjusted value, signal InF.1 is
activated (in the error list and via an output, if configured).
The monitoring timer starts when setting limit value C.Std. Reset of signal InF.1 in the error list will start a new
monitoring timer. Monitoring can be stopped by switching off limit value C.Std.
g
Adjusting the limit value for operating hours C.Std can be done only via BlueControl ® .
The current counter state can be displayed in the BlueControl ® expert version.
g
The number of operating hours is saved once per hour. Intermediate values are lost when switching off.
Number of switching cycles
The output number of switching cycles can be monitored. When reaching or exceeding the adjusted limit value, signal
InF.2 is activated (in the error list and via an output, if configured).
The monitoring timer starts when setting limit value C.Sch. Reset of signal InF.2 in the error list will start a new
monitoring timer. Monitoring can be stopped by switching off limit value C.Sch.
g
A switching cycle counter is allocated to each output. Limit value C.Sch acts on all switching cycle counters.
g
Adjusting the limit value for the number of switching cycles C.Sch can be done only via BlueControl ® .
The current counter state can be displayed in the BlueControl ® expert version.
g
The number of switching cycles is saved once per hour. When switching off, intermediate values are lost.
