General Information Checkout Procedure Measurement Expected Value
Checking the voltage that powers
the UC600 is often a necessary step
when commissioning or
troubleshooting. Operational issues
and LED operation may result in a
need to measure the input power.
When troubleshooting, it is faster to
take measurements while the load is
in place. If Step 1 indicates an out-
of-specification voltage, disconnect
the UC600 and measure the AC
voltage across the transformer.
These measurements can direct you
toward the problem source.
Step 1
Measure AC voltage with the
UC600 connected. Perform this
measurement while the unit is
under load.
20.0 Vac ≤ V
ac
≤ 30.0 Vac
Step 2
Measure AC voltage with the
UC600 unconnected. Perform this
measurement while the unit is not
under load.
20.0 Vac ≤ V
ac
≤ 30.0 Vac
