INSTALLATION AND STARTUP INSTRUCTIONS
1. Connect the PV panel and lighting load negative wires to the negative battery post. Connect the PVLC-15MD Red (+) wire
to the Battery positive post and the PVLC-15MD Yellow wire to the PV panel + wire. Connect the Motion sensor to the
PVLC-15MD using the 3 wire 18awg cable, red to (+), black to (-), White to (NC), Jumper between (-) and other (C).
2. Adjust the desired time range on the switch per PVLC-15MD switch lighting options.
3. Now connect the PVLC-15MD Black wire to the battery negative terminal to power up the PVLC-15MD. Verify that the initial
battery voltage is greater than 11V or 22V, and PV voltage is greater than 16V or 32V.
4. Twelve seconds after power up, the charge relay (red LED) will click the number of times per the switch position with “0"
being 10. If the switch did not get set to the desired position, disconnect the PVLC-15MD’s negative battery wire and reset
switch to desired lighting operation and timing range. Reconnect the PVLC-15MD's negative battery wire and verify the
desired timing range. If the open circuit PV voltage is above 16V (32V) and the battery voltage is below the “turn on”
threshold (12.7VDC), then the PV charge relay will energize, charging the battery. Every 4 minutes the PV relay will drop-
out momentarily to test for the presence of adequate PV charge sunlight.
5. To test the lighting function, wave your hand in front of the motion sensor. If lighting set for night only then disconnect the
PV Yellow wire, wave your hand in front of the motion sensor, the lighting relay (yellow LED) will turn on the lighting load.
6. Now disconnect the PVLC-15MD black wire and reconnect the yellow PV wire, and then reconnect the black wire.
7. Mount the PVLC-15MD securely with screws and coat the switch with silicone to insure that the entire module is waterproof.
Waterproof the electrical connections with silicone or grease.
Note: The PVLC-15MD is powered by either the battery or PV voltage, which ever is greater. The charge relay is only powered
from the PV voltage. If there is insufficient PV voltage when powering up the PVLC-15MD, the charge relay will only
click once after a 12 second delay. If there is sufficient PV voltage( >16V/32V), then after a 12 second delay the PV
relay will click out the switch position with “0" being 10 clicks, it then checks the Battery voltage, if its below the “turn
on” threshold, the charge relay energizes after a delay of 5 seconds. If battery voltage is above the turn on threshold,
then it will wait until it drops below the threshold.
