WIRING FOR ENGINE SLOW/SHUTDOWN
The Individual Shutdown for up to two engines is built into the Monitor Channels, 1 - 6 are for
one engine and 7 - 12 are for the other engine.
You can have either a closed contact that opens on Shutdown or an open contact
that closes on Shutdown, this must be specified at time of ordering.
The output for the Shutdown is from a 5 pole socket which is fitted to position 2 on
the Monitor - see drawing QMI-05-1096 Part 1-5.
Pins 1 and 2 are for channels 1 - 6
Pins 3 and 4 are for channels 7 - 12
NOTE: Channels that are not being used must be isolated - see Part 3-8.
If an alarm should occur the relays will remain in the alarm state until the Monitor
has been reset.
To reset the relays: turn the security key clockwise ¼ turn, then turn the key back
¼ turn to reinstate.
DETECTOR CONFIGURATIONS
NOTE: It is possible to give any combinations of Detectors with Shutdowns for
example - 2 banks of 6.
The appropriate drawing is delivered with each system.
The number of alarms and Shutdowns is determined at the time of ordering the QMI
system.
