When the
MX1
system is first powered-up, its default factory configuration will make its GP outputs
and ANC outputs turn on and off at approximately 30 second intervals.
Care should therefore be taken that the activation of outputs at first power-up will not cause adverse
effects. Ensure that alerting devices, brigade signalling, and other outputs are not initially connected, or
are otherwise isolated.
Note also that with the factory default configuration there will almost certainly be some combination of
unusual faults displayed
– some of which come and go as the outputs turn on and off. This is normal for
the default configuration.
A suitable site-specific database configuration should be loaded into the
MX1
before further connections
are made, and before any testing commences.
Temporarily disconnect the alerting device(s), and switch the
MX1
on.
The green “POWER” LED on the controller should light, and the yellow “C” LED should flash once a
second.
The LCD/keyboard will beep briefly, and the LCD will display its software version number briefly before
changing to the main
MX1
system display.
Within 30 seconds, the buzzer should sound. Press SILENCE BUZZER on the keypad to stop the noise.
Press FAULTS and verify that a battery connection fault is displayed. (This may take up to 30 seconds).
Connect the battery. The green “BATT CONN” LED on the controller should light, unless the battery is
very flat. If this LED does not light, briefly short together the pins of adjacent LK3 with a screwdriver or
similar. The LED should light, and the battery should start charging. If the battery is very, very flat, short
LK3 for a longer period until the charger can pull the battery voltage up enough.
Within 30 seconds, the battery connection fault should clear.
Temporarily connect one of the 0V terminals on the controller to the gear plate. Within 10 seconds, an
earth fault should be indicated. Remove the connection. The earth fault should clear within 10 seconds.
Note that connecting a PC to the Diag/Prog serial port may also generate an earth fault (depending on the
PC). This is normal and will clear when the PC is disconnected.
At this stage, all the field wiring can be connected to the
MX1
. If an earth fault occurs when a piece of
wiring is connected, this wiring should be checked and the fault cleared before proceeding further.
