System Start Up
Pr
ess the RESET key to clear any faulted sensor input and unground/enable
ignition for engine operation. Apply starting power to the engine.
The first thing displayed on versions with Tachometer is the engine speed.
While there is time remaining in either of the Class “B” timers, the display
will alternate between engine speed and the Class “B” timers (4 seconds
each). Once the Class “B1” timer expires, while there is time remaining in
the Class “B2” timer, the display will alternate between the engine speed and
the Class “B2” timer (4 seconds each). Once both Class “B” timers expire,
the engine speed is displayed continuously.
While there is time remaining in the Class “B1” timer, the display will alternate
between engine speed and the Class “B1” time remaining for example: “1 0:30”
(4 seconds each). All sensor inputs configured as Class “B1” are locked out at
this point. For non -T models the “B1” display will be steady. To zero this
timer, press TIMER “0”.
Once the Class “B1” timer expires while there is time remaining in the Class
“B2” timer, the display will alternate between engine speed and the Class “B2”
time remaining for example: “2 0:30” (4 seconds each). All sensor inputs
configured as Class “B2” are locked out at this point. For non -T models the
“B2” display will be steady. To zero this timer press the TIMER “0” key, after
the Class “B2” timer has expired.
To display the run hours, press the “DisplayHours” key. The current Run hours will
be displayed for 5 seconds. NOTE: On all non tachometer models (non -T) the
RUN HOURS are displayed after the Class “B” Timers expire, instead of ENGINE
SPEED. The decimal point flashes to indicate the unit is running.
If any one of the sensor inputs configured as an ALARM-ONLY is faulted, the
Alarm Output will turn ON, and the sensor number will be displayed in the first
two digits. Press the RESET key after the sensor input has cleared, to clear the dis-
play and to turn OFF the Alarm output.
If the engine speed exceeds the Overspeed Set point the engine will shutdown,
bypassing the Ignition Ground Delay. The TTDJ-T models will display “50”.
Overspeed overrides the Test mode.
If after the Class “B1” Timer expires the engine speed falls below the
Underspeed Setpoint, the engine will shutdown. The TTDJ will
annunciate/display “51”. Underspeed overrides the Test mode.
To manually shutdown the engine, press the STOP/RUN key. The TTDJ will
shutdown the system and the display will indicate “52”. Manual Stop over-
rides the Test mode.
Upon reaching a shutdown condition, the unit will trip the fuel valve, and, after
the delay expires, ground the ignition. This delay is bypassed on Overspeed
(50), Emergency Shutdown (32), and sensor input #29 if configured as Class
“ESD”.
TTDJ-IGN models annunciate/display “51” when ignition input is lost.
The energy stored in the FV+ circuit will trip the fuel valve.
After the shutdown condition is cleared on the equipment, press RESET key.
The Test Timer is used to verify that sensors are wired properly and working
correctly. To perform a sensor test while running do the following:
1.
Press the TEST key and verify that the Test Timer is shown with
5 minutes: (3 5.00).
2.
Trip the first sensor to be tested and verify that the sensor number and
class type appear on the display (see displays below). The display will
alternate between the Sensor Number and the Test timer.
3.
Clear the sensor then press the RESET key. Verify that the sensor num-
ber is cleared from the display.
4.
Repeat Steps 2 and 3 for each sensor.
5.
To exit, press the TIMER “0” key or allow the Test Timer to expire.
NOTE: Any of the following conditions will override the Test Timer:
Emergency Shutdown (32), Overspeed Shutdown (50), Underspeed Shutdown
-T models (51), Loss of Ignition (51) non-T models, Manual Stop (52), and
sensor input #29, if configured as a Class “ESD”..
In Test, when a sensor is tripped, he sensor number and the Class type are
displayed, for example if sensor #1 (01) a Class “B1” shutdown is tripped in
the Test the LCD reads “01 t1”. The following are the Test Mode Displays:
(t0): Class “A” Shutdown
(t1): Class “B1” Shutdown
(t2): Class “B2” Shutdown
(t3): Class “C” Shutdown
(t4): Class “A” Alarm
(t5): Class “B1” Alarm
(t6): Class “B2” Alarm
(t7): Class “C” Alarm
