sequence. It will stay on a step during the 15 seconds of wait and on the 15 seconds of cranking and then will count
on until the sixth step, which is the end of the cranking sequence.
E: Diesel engine. It will be grey if the engine is stopped, green if an “Engine Run” signal is detected and red if an
“Overspeed” or “Fail to start” occurred, after 6 unsuccessful cranking attempts. The engine will be yellow if running
in test mode.
F: Representation of the motor starting or stopping cause. A green capsule will indicate the reason why the engine
is running, and a red capsule will indicate reason it is not running when it should. Possible choices are:
LOCAL – Optional: This start cause is triggered if the engine is locally started directly from its own control panel and
the option is enabled.
MANUAL – It receives a manual crank request from one or both of the manual crank membrane buttons while the
selector switch is the “HAND” position.
EMERGENCY – Optional: It receives a manual crank request from the emergency pushbutton while the selector
switch is the “HAND” position.
REMOTE MANUAL: Manual engine starting activated by a remote start contact.
DELUGE: Automatic engine starting activated by a deluge valve.
PNEUMATIC: Optional: Automatic engine starting activated by the “Fail to Start” Alarm.
AUTO: Automatic engine starting activated by pressure drop.
REMOTE AUTO: Automatic motor starting activated by remote equipment.
WEEK TEST: Automatic motor starting activated by a scheduled test.
MANUAL TEST: Automatic motor starting activated by the run test pushbutton.
AC FAIL – AC Fail will count the time following an AC Failure and at the end of a predetermined timer, will start the
engine with an AC FAIL request when this option is enabled.
A red capsule will indicate the reason why the motor is not running despite the fact that a request is being made.
Possible causes are:
DC FAIL – This failure happens when the controller receives a request to start, but has no DC Power, thus
preventing its ability to effectively start the engine.
OVERSPEED – This start cause happens when the controller receives a request to start, but the engine sends an
“Overspeed” signal, thus preventing its ability to effectively start the engine.
FAILSTART – This failure happens when the controller receives a request to start, but a “Fail To Start” alarm is
active after a cranking sequence failure, thus preventing its ability to effectively start the engine until this alarm is
reset.
LOCKED: An interlock signal is preventing the motor from running.
G: Operations timers including the sequential start timer, the run period shutdown timer, the manual test timer, the
weekly test timer and the AC Fail timer.
H: The HOA Selector switch. The three positions indicate the actual position of the HOA, “HAND” for manual mode,
“OFF” and “AUTO” for automatic mode. The controller should always be left in the “AUTO” position.
I: Discharge pressure gauge. It allows for a precise reading of the actual system pressure. The red box on the
upper left corner of the gauge indicates the value of the Cut-In set point and the green box on the upper right corner
