Control Tests

TB8100 Service Kit User's Manual
The Service Kit lets you test aspects of the PMU and monitor additional details
of its operation.
The Control Tests form lets you simulate an AC mains failure. You can also
check that the fan, the fault LED, and the auxiliary output are working.

Simulating AC Mains Failure

The Control Tests form lets you simulate an AC mains failure so that you can
test the base station's battery backup and the PMU's DC-DC converter. This
simulation is not available if there is no DC power supply or if its voltage is too
low.
This test affects any other base station in the subrack.
Important:
To simulate an AC mains failure
1. Select Diagnose > Power Management > Control Tests.
2. Click Start Test at the bottom of the Control Tests form.
3. Click Mains Failure Test.
4. Check that power to the PA and the Reciter/control panel stays on.
5. Click Stop Test.

Testing the Fan

You can ask the base station to turn the PMU fan on and off; this tests the fan
and its control circuitry.
