User Manual
The measurement is derived from the measured period time of the number of pulses
configured per revolution.
The number of input pulses per revolution must be 1 when the
channel is used as trigger for Piston Rod Drop.
There is a peak speed detection function. Peak speed for a digital channel will be stored
(as events) if both of the following conditions are met:
•
The detected peak speed value is above alarm level
•
No new peak speed value is detected within 1 minute
The 1 minute delay is to avoid numerous events during
acceleration. This will also mean that the event will be generated
after 1 minute from the detection of the peak speed. The time
stamp in the event is the time of the detection.
Important: Peak speed will not be updated during slot disarm.
–
Peak speed value is available through Modbus and Event Log.
–
It is possible to reset (set to zero) the peak speed value via the local display, the
imported (write single) Modbus register
and Ethernet (Observer).
Important: Reset of peak speed will reset all peak speed values within the slot.
