Troubleshooting

Service

Testing the Assembly

You can use the tests and checks in Table 4-2 to isolate the problem. See Figures 
3-1, 3-2, and 3-3 in Chapter 3 for locations of mechanical parts. See the 
component locator included with this manual for locations of electrical 
components.

Checking for Heat Damage

Inspect the assembly for signs of abnormal internally generated heat such as 
discolored printed circuit boards or components, damaged insulation, or 
evidence of arcing.

Checking Switches/Jumpers

Verify that the logical address switch is set correctly (factory set at 120). Verify 
that the interrupt priority jumpers are set correctly (factory set at level 1).

Checking the Switch Module PCA

Check the following:

–

?

   Verify that fuses F601 and F602 are good.

–

?

   Check connectors J1, J2, P1, and P2 for damage.

–

?

   Perform Test 2-1 in Chapter 2.

Matching Relays to Channels

Use Table 4-3 to help match channel numbers to relay and drive circuit reference 
designators.
