MODULE FUNCTIONAL TESTS

6 - 7
expander bus testing requires a powered MMU slot, an MFP,
an MFP interface device, and slave expander bus dipshunts.

Table
lists the switch settings used in both parts of the
functional test.
HALT - DISPLAY ERROR
SW1 pole position 2 is the error halt/continue bit. A one in this
position when in diagnostics mode instructs the slave to stop
testing when an error is detected. The slave will loop on dis-
playing the error code of the failed test.
If the test or group of tests passes, the LED will turn off
momentarily at the start of the test and display solid green
during the test (or tests).

1. An error code of 30 or 40 will be followed by an error code indicating which input channel is not
functional. For example, an error code of 30 followed by an error code of 7 indicates that channel
7 is not functional. In this example, the LED will continue to display 30 and 7. The LED error se-
quence repeats every 6 seconds.
2. x = 0
Continue looping on tests. Do not display error.
x = 1
Halt on test failure. Display error code.
