The Diagnostics screen consists of the following:
First and Fourth columns; "UCO#1 N/A" through "Test All Outputs" - The first column handles the
UCO#1 option and the fourth column handles the UCO#2 option. Both sets of controls operate
identically. The indicators "UCO#1 N/A" and "UCO#2 N/A" indicate that the UCO options are not
available. When they are available the indicators read "UCO#1" and "UCO#2".
The "Selected Output:" indicators show what output is selected for test. The "Select Output" push
button sequentially steps through all of the 32 outputs. The "Test Output" push button will activate
the selected output for as long as the operator holds the button. The "Test All Outputs" push button
will trigger a sequential test of all 32 outputs. Each one will be activated for one half second.
Second Column; "Alarm Relay Test" through "Horn Relay Test" - The array of 4 push buttons allow
the operator to test all of the common alarming relay outputs separately. The outputs are activated
for as long as the button is pushed.
"No Forced Defaults" - When the push button indicator is visible as shown system operation is
normal. When the Compactlogix processor loads the factory default program from the SD card, this
push button indicator appears flashing as "-DEFAULTS- Reset Flag". When this happens, any user
entered parameters are lost and the MSA factory defaults are loaded. See section 4.2.10 for
instructions on how to restore saved user settings from the SD card. The processor restoring from
factory defaults is classified as a trouble condition and the source of the processor action must be
determined. The only normal cause for this is battery failure followed by power being turned off long
enough for internal capacitors to discharge. This event should be rare assuming the MultiGard 5000
system is powered up most of the time while in service. This condition flag can be reset by pressing
this button.
WARNING
If “-DEFAULTS- Reset Flag” indicator flashes, all user entered
parameters are lost and the MSA factory defaults are restored.
Immediate action is required! The cause of this condition must be
determined and corrected. This condition requires the operator to
manually re-enter all user configured parameters to restore
MultiGard 5000 unit to its most recent desired operation. If no
action is taken the MultiGard 5000 unit will remain in default
operation with only common alarming as defined in Section 1. This
results in operation identical to the initial delivery of MultiGard
5000 unit.
"Reset Sensor Alarming Disable Time-Out" - This push button resets the sensor alarming disable
time-out timer if it is necessary to extend the function. The time remaining until alarming is restored
is shown on this button.
