ILC LightLEEDer Operation Manual
Version 1C 3/14/17
Phase Monitoring Module Configuration and Wiring:
The lightleeDer panel provided with optional Phase Monitoring Module will require field wiring the phase “B” and
phase “C” un-switched normal power to the PMM.
1. Verify the PMM is installed and power from the transformer is connected to “FROM TRX 24VAC CT”
terminal.
2. The “TO RelAYs” terminal will feed the power distribution card. (see Figure 4)
3. normal un-switched phase “A” power will feed the panel transformer.
4. Phase “B” and “C” un-switched normal power will connect to the PMM terminals, along with a normal power
neutral.
5. Verify the disable jumpers are removed for phase “B” and “C” monitoring operation.
6. switch on the three circuits to be monitored and verify that the A, B, C phase status leD’s on the PMM are lit.
7. Test operation using the Test button to trigger the PMM.

Figure 3 - Phase Monitoring Module detail
The Phase Monitoring Module is provided with mounting back plate and barriers for voltage division, along with
a monitoring input terminal label for phase B and C connections. When installing the PMM in the panel, it is nor-
mally mounted in upper right section taking up relay locations 2 & 4. The PMM can be installed in another area of
the panel, but the wiring leads for the 24VAC CT would need to be extended.
