diagnostic routines test the operation of the module compo-
nents and circuitry. This section describes how to use the diag-
nostic routines and provides a brief description of each test
routine.
Set pole 1 of SW3 to off (OPEN) to enable hardware diagnostics.
Faceplate LEDs display the test results. SW2 selects the group
test or individual tests to be run.
Select a diagnostic test to run, then set the dipswitches and
reset the module. Observe the test results on the faceplate LED
display. The selected test runs repeatedly until the IMCPM02
module is reset or another test is selected on dipswitch SW2.
Dipswitch Selection
This section describes the settings and function of dipswitches
SW2 and SW3. Figure
shows the dipswitch location on the
IMCPM02 module.
Pole 1 of dipswitch SW2 selects the LED display mode. Pole 2 of
dipswitch SW2 selects a halt on error feature. In this mode, the
IMCPM02 module will halt test execution whenever the
selected test detects an error. The number of the failing test is
displayed on the front panel LEDs.
On dipswitch SW2, poles 3 through 8 select a diagnostic test to
run. Pole 8 is the least significant bit (binary weight 1). Pole 3 is
the most significant bit (binary weight 32). Refer to Table
for dipswitch SW2 settings for diagnostic mode. Refer to Table
for test ID values.
