UCM Calibration

1.
Adjust the Cut Alarm parameters, if required (S2 = Time Window {S2 also affects the Climb
Alarm settings} S3 = Cut Count).
2.
Test the Cut Alarm settings by making a series of impacts along the protected surface.
3.
If each of the Cut simulations register as Cut Counts and lead to alarms, use the current
settings and monitor the system for nuisance alarms.
4.
If the Cut simulations do not register as Cut Counts and do not cause alarms, adjust the Cut
Alarm parameters and repeat the tests.
OR
Increase the Gain/Threshold setting 1 level, and repeat the Cut Alarm tests.
Note
The Cut Profile is an advanced parameter, which can be adjusted
only through the UCM, For switch calibration, the Cut Profile is ON at
the default setting of 20%. This means that each time an Impact is
recorded, 20% of the Climb Window setting is added to the time
remaining in the Climb Window. (see
Note
If there no Gain/Threshold setting functions for both Cut alarm and
Climb alarm detection, change the Filter Response band, and repeat
the calibration procedure.
If the Gain/Threshold setting is at the maximum level, and detection is
not adequate, redeploy the sensor cable using reduced cable
spacing. Ensure that the cable is in close contact with the protected
surface. Repeat the calibration process after modifying the sensor
cable layout.
OR
If a functional Gain/Threshold setting cannot be found, calibrate the
system with the UCM.
