Section 4 – Trouble Shooting

Before beginning any trouble shooting, check all wiring and look for any loose connections. Double

check your wiring! The tracker expansion board in some applications may have over 20 wires

connected directly to the board terminal strips. Be sure that you have a good VOM (Volt-Ohm-Meter)

to assist you when checking voltages and continuity.

Check the programming switches to be sure that the tracker board is setup to operate as desired. If

more that one tracker board is connected in the system, be sure the board jumpers are set correctly.

Be sure that the tracker board is powered (16 VAC). The POWER led should be ON when power is

applied to the tracker board. A backup battery should be connected to the tracker board as described

in section 4.2.
