Troubleshooting
This chapter outlines some general troubleshooting steps that should be
performed if there is a problem with the operation of the equipment con-
trolled by the Tracer MP503. This chapter describes some common prob-
lems; however, it cannot describe every possible problem. Troubleshooting
that involves accessing live electrical devices must be conducted only by a
properly trained and authorized electrician or trained technician.
If you encounter operational problems with the Tracer MP503 I/O mod-
ule, you must first perform initial troubleshooting steps; see "Initial trou-
bleshooting" on page 32.
After you have performed the initial troubleshooting steps, refer to spe-
cific sections in this chapter to further diagnose the following operational
problems:
• If a binary output is not turning on the equipment wired to it, see
"Binary output (relay output) troubleshooting" on page 33.
• If you see a universal input value that appears incorrect, see "Univer-
sal input troubleshooting" on page 35.
