7.3 Preventative Maintenance
Perform preventative maintenance on the Alpha FXM module every 6 to 12 months. For mission critical
applications such as backup traffic intersections, more frequent maintenance should be done. Proper
implementation of the following procedure will insure that your system continues to provide reliable backup power
in the event of a utility power failure.
7.3.1
Tools and Materials Required
Wrench set.
Labels and marker to number batteries.
Conductance meter for optional conductance test.
7.3.2
Procedure
1. Inspect the Alpha FXM and wiring for any physical damage. Repair or replace as required.
2. Verify that all connections are securely fastened. Tighten if necessary.
3. Inspect the batteries for cracks or swelling. Replace all four batteries if any of the batteries are cracked or
swollen. Replace only a faulty battery if an Alphaguard battery balancer is installed.
4. Inspect the battery terminals for corrosions. Clean and apply a corrosion prevention compound such as
NOCO Company NCP-2 or Sanchem Inc. NO-OX-ID if required.
5. Re-tighten the battery terminal bolts on Insert Terminal batteries. Re-torque the battery terminal bolts on
Flag Terminal batteries to the manufacturers specifications on if required.
6. Label the batteries #1, #2, #3 and #4. The battery negative cable from the Alpha FXM is connected to
Battery #1, and the battery positive cable from the Alpha FXM is connected to Battery #4.
7. Verify that the battery temperature probe is securely taped to the side of either battery #2 or #3.
