6.6.1 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 acti-
vated (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 moni-
toring 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 moni-
toring 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.
The number of switching cycles is saved once per hour. When switching off, intermediate values are lost.
6.7 Analog output configuration
6.7.1 Analog output (optional)
An analog output is available as a display output.
The two output signals (current and voltage) are available simultaneously. Adjust ConF / Out.3 / O.tYP to se-
lect the output type which should be calibrated.
ConF / Out.3: O.tYP = 1 Out.3 0...20mA continuous
= 2 Out.3 4...20mA continuous
= 3 Out.3 0...10V continuous
= 4 Out.3 2...10V continuous
