DIAGNOSTICS
This section describes how to use the diagnostic routines to verify that the MLP–Trim is
operating properly as well as to identify any MLP–Trim problems. The diagnostic
routines are run independently, with the MLP–Trim temporarily disconnected from your
system. Begin diagnostics with the Clear/4 procedure, then run tests 1-6. Each of the
tests can be performed without repeating the Clear/4 procedure unless you exit
diagnostics.
If you need to verify the integrity of the MLP–Trim relative to your system, refer to the
Troubleshooting: Troubleshooting section. If the information in this section does not
solve your problem, consult:
Contrex Technical Support (763) 424-7800 or (800) 342-4411
Clear/4 - To Begin the Diagnostic Procedure
To begin the diagnostic procedure, turn the MLP–Trim off and disconnect it
from your system.
Turn the power on the MLP–Trim while simultaneously pressing “Clear” and
“4” on the keypad.
The MLP–Trim defaults to RAM Test #1. The Diagnostic indicator and the
number “1” are visible on the left side of the LED display. If you did not see
this indicator, you are not in diagnostics. The example below shows the
diagnostic indicator and test number on the LED display.
