user will be prompted again to “press any key” and the alarm 3 relay will be turned on. The user will be
prompted again to “press any key” and the fault relay will be turned on. The user will be prompted again to
“press any key” and all the relays will be reset. The user will then be prompted to connect COMM1
(master) to COMM2 (slave) for a Modbus™ loop back test and “press any key” to continue. This will
initiate test 1 of 4 which performs a Modbus™ communication test at 4800 baud rate. The test will
perform 127 iterations and indicate the number of errors received if any. The user has the option to abort
the test at any time by “pressing any key”. Once test 1 is complete or has been aborted by the user, test 2 of
4 will initiate automatically and perform 127 iterations of the Modbus™ communication test at 9600 baud
rate. Test 3 of 4 will follow at 19200 baud rate and finally test 4 of 4 will be performed at 38400 baud rate.
All four tests can be terminated at any time by the user. When these tests are completed the display will
revert back to the SYSTEM DIAGNOSTICS menu.
NOTE: The Modbus™ loop back test cannot be performed on the CXT controllers, as the
COMM2 (slave) port is not accessible to the user. This test should be aborted by the user.
