Sequence of Operation
Diesel Engine Fire Pump Controllers
ENERGIZING THE CONTROLLER
1. Place MANUAL-OFF-AUTO selector switch in OFF
position
2. Close circuit breaker 1CB to allow single phase AC
voltage to the battery chargers.
3. Close circuit breakers 2CB and 3CB to allow battery
DC voltage to the battery chargers, and all other
DC voltage components in the controller.
Note : Selector switch in OFF position is an alarm
condition, and the Alarm LED will be flashing. Also, the
START and STOP pressure set points should be
programmed into the Mark II, and the System should
be pressurized at or above the STOP set point. See the
Setup and Operating Instructions Manual for details.
4. Selector switch should be placed in AUTO for
automatic start on loss of pressure. The Mark II will
show system pressure, and battery voltage. Main
Switch in Auto LED will be illuminated.
5. The controller is now in standby condition and is
ready to start the diesel engine should a start
signal be received.
MANUAL START
1. Place MANUAL-OFF-AUTO selector switch in
MANUAL position.
a. “Alarm” LED will flash.
b. “Main Switch in Auto” LED will go out.
c. “Engine Oil Pressure Low” LED will illuminate.
d. Engine fuel and water solenoid will energize
through terminal #1, and engine shutdown circuit
will de-energize through terminal #12.
2. Press CRANK ON BATTERY #1 and/or CRANK ON
BATTERY #2 push-button(s).
a. Engine starter will energize through terminals
#9 or #10 respectively.
Note: Hold the crank push-button until engine starts,
then release.
CAUTION—Engine starting motor may be damaged due
to excessive continuous cranking. Limit continuous
cranking time to fifteen (15) seconds. Allow at least fifteen
(15) seconds rest before attempting to re-crank.
b. “Engine Running” LED will illuminate once the
engine is running.
c. “Engine Oil Pressure Low” LED should go out
once oil pressure is satisfied.
Note: Engine mounted oil pressure switch must open
and de-energize terminal #4 within 15 seconds after the
engine is running. If not, the controller mounted audible
alarm will sound.
CAUTION—Low Oil Pressure condition outlined above
may result in engine damage. IMMEDIATELY place the
selector switch in the OFF position. DO NOT RUN
ENGINE until problems have been resolved.
3.
Engine will keep running until it is shutdown by
placing the selector switch in OFF position or the
engine over speed switch operates.
AUTO START
CONDITIONS NORMAL
1. Place MANUAL-OFF-AUTO selector switch in
AUTO position.
a. “ Main Switch In Auto” LED will illuminate.
2. Push ENGINE TEST push-button on controller inner
panel and hold depressed until engine starts and
runs.
•
FTA1100
NOTE— Pressing this button energizes the SVR relay
(solenoid valve relay), and the solenoid drain valve on
controller, bleeding pressure from the pressure transducer
causing engine controller to automatically start the
engine.
3.
4.
5.
6.
Release TEST push-button after engine starts.
Cranking will cease.
a. “Engine Running” LED will illuminate, the SVR
relay (solenoid valve relay) will de-energize, and
the solenoid valve will be de-energized, satisfying
system pressure.
b. If Mark II is programmed for Automatic Start,
and Manual Stop Only, the controller will stop
only if pressure is restored at or above the STOP
set point. The main selector switch can be turned
to the OFF position, or the STOP RESET
BATTERY TROUBLE push button can be
depressed. If all requirements are normal, the
engine will shutdown.
c. If Mark II is programmed for Automatic Start and
Automatic Stop, the controller will automatically
stop the engine after the minimum run period
expires and all conditions are returned to
normal.
Signals for Auto-Start are as follows:
a. System pressure drops to Start set point .
b. Remote Start contact closes.
c. Deluge valve contact opens.
d. Weekly test automatically performed or ENGINE
TEST push-button depressed.
Occurrence of any of the call to start conditions
energize:
a. Fuel and water solenoids through terminal #1
and de-energizes the engine shutdown circuit
through terminal #12. NOTE: Either terminal #1,
or terminal #12 is used, depending on engine
make.
b. Engine cranking circuits through terminals #9
or #10.
c. Minimum run period timer (for auto shutdown
only). Minimum run time is a function of the
Mark II.
Cranking circuit operates as follows:
a. Mark II crank limit timer starts 165 second time
cycle to limit total cranking duration time.
b. Timer sets 15 seconds crank period.
c. Timer sets 15 seconds rest period between
cranks.
d. Cranking alternates between battery—1 and
battery—2. Three 15 second cranks per battery.
NOTE—In the event that a battery is inoperative, the
respective battery will be shown on the Mark II display
as “Battery Trouble”. This will prevent the battery
alternating crank cycle from operating and will lock the
cranking circuit onto the remaining battery.
e. If the engine does not start within the 165 second
time, the timer will expire in the Mark II and
energize the engine trouble alarm relay, ETR,
de-energize the cranking circuits, sound the
audible alarm, and “ Engine Fail To Start “ LED
will illuminate. Placing the selector switch in
the OFF position will reset the control circuits.
CHECK THE ENGINE STARTING EQUIPMENT
AND FUEL SYSTEM.
7. When engine reaches running speed, the engine
mounted speed switch will close to terminal #2,
engine running relay ERR will energize, and the oil
pressure timer in Mark II. “Engine Running” LED
will illuminate.
a. Remote engine running alarm contacts are
activated.
13.
b. Energizing ERR inhibits the crank output circuit
in Mark II.
8.
9.
Engine oil pressure should increase, opening the
engine mounted low oil pressure switch.
If the oil pressure fails to increase, the oil pressure
timer will time out (15 seconds), sound the audible
alarm, and energize relay ETR to activate the remote
engine trouble alarms. The controller does not
shutdown the engine on low oil pressure unless the
start was initiated by a test condition (Weekly Test
or Engine Test push-button).
CAUTION—An engine running with a low oil pressure
condition may be damaged. If operation of the engine is
not essential at this time, it should be shutdown by
placing the selector switch in the OFF position. All
possible causes of low oil pressure should be investigated
and corrected immediately so that system can be
returned to normal operation.
10. Whenever the controller selector switch is in the
MANUAL OR AUTO position, the engine water
temperature is monitored through the temperature
switch on the engine. Closure of this contact through
terminal #5, will signal Mark II to energize the audible
alarm, relay ETR and activate the remote engine
trouble alarm. This will not stop the engine, nor will
it prevent the engine from starting. Note: A test
condition will stop the engine.
CAUTION—An engine running with a high temperature
condition may cause engine damage. Causes of high
temperature should be investigated and corrected
immediately.
11. An engine overspeed condition will immediately
shutdown the engine and lock it out until the
overspeed switch on the engine has been reset.
(Overspeed is normally set at 120% rated RPM.)
The overspeed switch on the engine will operate to
close the engine fuel valve and energize controller
relay OSR. “Engine Overspeed” LED will illuminate,
the audible alarm will energize, relay ETR will
energize and activate the remote engine trouble
alarm. Relay ERR will de-energize, deactivating the
remote engine running alarm signals. The engine
overspeed switch must be reset manually before
the engine can be restarted. The audible alarm on
the controller and the remote engine trouble alarm
may be silenced by placing the controller switch in
the OFF position. If the control switch is placed in
the AUTO or MANUAL position before the engine
overspeed switch has been reset, the audible alarm
on the controller and the remote alarm will be
reactivated. NOTE: The engine is solely responsible
for engine shutdown in overspeed.
12. Weekly test timer—Operation of weekly test timer,
will energize the solenoid drain valve on the controller
to take the transducer to atmosphere, initiating an
automatic run sequence. The engine will run until
the weekly test timer resets (minimum 30 minutes)
14.
15.
16.
and all other demand signals have been satisfied. If
the engine continues to run, it indicates that some
other demand still exists.
An engine start by weekly test timer, or Engine
test push-button, is considered a nonessential start.
Safety engine shutdown circuits for the following
conditions are included in this controller:
a. Engine overspeed.
b. Engine low oil pressure.
c. Engine high temperature.
Shutdown by engine overspeed requires manual
reset of the engine overspeed switch.
Shutdown by low oil pressure and high temperature
would be voided by any other demand for engine
run operation.
Interlock shutdown—Closing of the interlock
contacts will disable all automatic starting and
automatic running functions but will not affect
manual start or manually started running functions.
SHUTDOWN—OTHER THAN
CATERPILLAR ENGINES
Shutdown normally occurs when pressure is restored at
the transducer and the minimum run time expires. Mark
II performs the functions of a holding circuit to allow the
timing of the crank circuit and also of energizing wire 1
(terminal #1) on the engine, energizing the fuel solenoid.
When all start conditions are met, the fuel solenoid deenergizes, stopping the engine.
The above sequence requires that Mark II be programmed
for automatic shutdown (minimum run time). If
programmed for Manual Stop Only, the engine must be
stopped manually.
SHUTDOWN—CATERPILLAR ENGINES
Caterpillar engines require that the fuel solenoid be
energized to shutdown. (Main selector switch, MANUALOFF-AUTO must be in OFF or AUTO). This allows wire
12 (terminal #12) to become energized, and the
shutdown circuit on the engine to become energized.
These conditions allow the engine fuel solenoid to
energize to stop the engine if Mark II is programmed for
Automatic Stop.
OVERSPEED—SHUTDOWN
Engine overspeed is a shutdown condition and is
detected by contacts mounted on the engine which signal
through terminal #3. OSR1 will energize, “Engine
Overspeed” LED will illuminate. Mark II prevents any
call to start, disabling the weekly test circuit and the
manual Engine test circuit. Terminal #1 remains
energized to supply voltage to overspeed circuits on the
engine.
The Caterpillar engine requires energizing the fuel
solenoid to stop. In an overspeed condition, wire 12,
terminal #12, will be energized, stopping the engine.
Overspeed disables the crank cycle, prevents all calls
to start, disables the weekly test circuit and the manual
test circuit.
