Hayward ProLogic Troubleshoot Manual

24
If the local display shows a blank display or no lights are illuminated an abrupt power
outage may have been the cause, in this case, resetting the unit may correct this
problem.
Turn the main system breaker ON and verify that
120VAC of input power is present. IF no/low voltage,
correct the source power issue. IF voltage is correct,
proceed to step 2F.
With power OFF, disconnect display, and restore
power. Verify, across pins 1 & 3 (left to right) for 5-
11VDC. IF no/low voltage replace main board. IF
correct, replace display (see pg. 17).
Test incoming power

2. Blank Display/No LEDs (cont.)
NOTE: Verify the main board’s input power comes from positions 3 & 4 on the terminal block, which
is labeled “Control Power”. The two bottom left terminal blocks are factory installed for SENSE &
DISPENSE OUTPUT POWER ONLY, AND SHOULD NOT BE USED TO POWER THE MAIN SYSTEM
BOARD.
