Introduction
Part1-6
4. FUSES
There are 4 fuses on the MULTIPLEX Power Supply Board, see Fault Directory in Part 4.
FS1
(Q0114) is a 1.25A anti-surge fuse. This is connected to TR1 and is the supply to
the Sensors. The LED 1, which is underneath, will flash when all is well.
FS2
(Q0112) is a 400mA anti-surge fuse for 12V power to the fans. The LED will light
when all is well.
FS3
(Q0112) is a 400mA anti-surge fuse to protect the Data Logger PCB and also has
a Green LED3 light which is lit constantly (not flashing).
FS4
(Q0115) is a 3.15A anti-surge fuse and is fitted to the side of the Monitor.
5. SECURITY KEY SWITCH (Part 1-3)
The Chief Engineer possesses the only set of keys (Q0103) to change settings. It is
possible to check the settings without using the security key switch, see Part 3-4.
NOTE:
The Monitor does not have an on/off switch this is to prevent the oil mist
Sensors from being switched off. To turn off the power disconnect the power supply.
