System Self Test
The system self test is utilized to locate typical problems.
See Table 6-6, System Test Descriptions and Table 6-7,
System Test Messages for information concerning the
tests performed and available messages in this mode.
1.
When the keys witch is in the platform position and
the self test enabled, the self test function will test all
valves, contactors, platform inputs, indicator lamps,
and system alarms for various fault conditions.
When the keys witch is in the ground position, the
self test function will test all valves, the line contac-
tor, ground control inputs, and the ground alarm out-
put for various fault conditions.
2.
In order to test the inputs on the machine, the con-
troller will ask the service technician to perform vari-
ous tasks at the appropriate operator control station.
An example of this is “Close LLU Switch”. The con-
troller expects the operator to close the lower lift up
switch. When the controller sees that the lower lift up
switch has been closed, it will move on to the next
input, lower lift down LLD. If the switch is faulty or the
wiring is faulty, the controller will not move on to the
next input. The controller will continue to wait for the
closure of the input. If the operator knows the switch
is faulty and wants to continue the tests he must
simply press the enter key on the analyzer to con-
tinue.
3.
After the controller has conducted the tests from the
chosen operator station, it will display “TESTS COM-
PLETE”. This indicates that the controller has
checked all inputs and outputs for that station.
IN ORDER FOR THE MACHINE TO FUNCTION AFTER THE SELF
TEST IS COMPLETE, POWER MUST BE RECYCLED USING THE
EMS OR THE KEY SWITCH.
