US
US Patent 6,144,116
(model TTDJ-IGN-T only)
CSA Certified for Use in Class I, Div. 2,
Groups C and D Hazardous Areas.
Liquid Crystal Display
The TTDJ is a solid-state fault annunciator and shutdown control system,
with hour meter, designed to protect engines, compressors and their associated equipment. Four TTDJ modules are available:
TTDJ-DC : Powered by 12 or 24 VDC systems without tachometer and overspeed sensing. Includes RS485 serial port.
TTDJ-DC-T : Powered by 12 or 24 VDC systems with internal
tachometer and overspeed sensing. Includes RS485 serial port.
TTDJ-IGN : Powered by negative ground CD ignition systems
without tachometer and overspeed sensing. Without RS485 port.
TTDJ-IGN-T : Powered by negative ground CD ignition systems
with internal tachometer/overspeed sensing.Without RS485 port.
The Liquid Crystal Display sequentially provides shutdown/alarm
condition, run hours, rpm, and timer information. A shutdown or
alarm condition is indicated by the appropriate sensor number in
the first two leftmost digits. Hours display uses all the digits. RPM
display is shown in the rightmost digits with a Run Indicator in the first
digit. The Timer display shows the timer number in the first digit and the
time in the last three digits.
All TTDJ models will accept 32 sensor inputs from normally open and/or
normally closed sensors. Each of the first 16 inputs can be configured for
Shutdown or Alarm Before Shutdown*, and can be locked out by one of
the Two Start-Run timers (B1:0-5 min.; B2:0-9:59 min.), or configured as
Class C. The annunciator provides for both closing of a fuel valve, and
grounding of an ignition after a time delay. The TTDJ has built-in Elapsed
Time Meter. Run Hours and Tachometer Settings are stored in nonvolatile memory, as well as the last 4 shutdowns and one alarm (alarm
only stored if active at the time of shutdown). The TTDJ liquid crystal
display annunciates any fault from the sensor inputs, displays engine
speed and elapsed time.
Other features for all TTDJ models are: built-in Test Mode to test the sensor
circuits without shutting down, on-board backup battery to retain the fault
display after shutdown (IGN models only), and a history of the last 4 shutdowns with their associated Run Hours, also stored in non-volatile memory.
TTDJ-DC and TTDJ-DC-T models feature an RS485 serial communications
port (MODBUS RTU slave) to interface with micro-controllers, PC’S,
PLC’s and controllers.
Power and Control Inputs/Outputs
Module/ Head
The module is the brain of the control system. It contains the microcomputer, the Liquid Crystal Display (LCD), the membrane keys for configuring the sensors inputs, the Sensor Inputs Terminal Blocks and the Power
Inputs and Control Output Terminal Block. The TTDJ-DC module also
includes an RS485 serial communications port (MODBUS RTU slave).
*Alarm Before Shutdown is a function that causes annunciation and the alarm output, but will not cause a shutdown.
Timers
Active Timers are indicated by the timer number in the first digit of the display, and the remaining time in the last three digits. Timer 1= Class “B1”,
Timer 2= Class “B2”, Timer 3= Test, Timer 4= Ignition Ground Delay.
The TTDJ power and control inputs and outputs are connected to the
Power Inputs terminal block on the back of the TTDJ.
In the TTDJ-IGN and TTDJ-IGN-T the FV+ output is a non-switched output that supplies stored energy from an internal capacitor. -FV and
ALARM outputs are non reversible switched outputs (switched OFF for
normal operation, switched ON for alarm and shutdown). When a shutdown fault is detected, the -FV and ALARM turn ON and after a time
delay, the IGN input switches to ground. The alarm output does not
operate for Manual Stop (code 52).
On the TTDJ-DC and TTDJ-DC-T the IGN, FV, and ALARM outputs
are programmed to switch ON for normal operation.
Sensor Inputs and Terminals
Up to 32 dry contact sensor inputs or Murphy device transistor outputs
can be connected to the back of the TTDJ via a terminal block (32 pair,
screw type, each with a jumper). Sensor inputs 1 to 16 are configurable as
Class“A”, Class “B1”, Class “B2” or Class “C” functions, Shutdown or
Alarm Before Shutdown*. The Class“B” timers allow sensor inputs to be
locked out at start-up. Sensor inputs configured for Alarm Only will cause
the Alarm Output to turn on when tripped, and the sensor number will be
annunciated while the unit continues to run. TTDJ sensor inputs 17-28 are
dedicated as Class “A” Shutdown only. Sensor input 29 can be configured as a
Class “A”, or Class “ESD” input. Sensor input 32 is dedicated as Class “ESD”.
Sensor inputs 30 & 31 can have special functions or be Class “A”. Any
tripped sensor is detected within 1 second after faulted.
TTDJ-99062N page 1 of 8
GENERAL INFORMATION Continued from page 1
Emergency Shutdown
Sensor input number 32 is dedicated to Emergency Shutdown. The
Emergency Shutdown sensor input overrides the Test timer. Additionally,
sensor input 29 can be configured as a Class “A” or Class “ESD” input.
Remote Reset
(optional, Setup 5 = 1, 3, 5 or 7)
When the Remote Reset feature is selected, point 30 with a closed contact
resets the TTDJ in the same manner as when using the Reset key. The
closed contacts to operate the Remote Reset feature should be kept closed
only momentarily for approximately 1 second to cause a remote reset.
Remote Lockout (optional, Setup 5 = 2, 3, 6 or 7)
The Remote Lockout inhibits the Class B1 and Class B2 Lockout timers.
These Lockouts are ignored when a closed switch is seen at Input 31. An
open switch at Input 31 allows the Lockouts to function normally. When the
Remote Lockout is active it resets Class “C”, “B1” and “B2” Lockout timers.
This is intended to be used with automatic starting systems. With a contact closure on terminals 31 with the unit not running, the display will
alternate between either RPM (-T models) and the Class “B1” timer, or
the display will flash (non-T models). The TTDJ should be put into
remote lockout immediately before stopping the engine. The contact closure should be opened once the engine is running. At that time the “B1”
and “B2” timers will be allowed to count down.
Reset Key
at shutdown, as well as the elapsed time reading at which they occurred.
For instance, if the unit is shutdown from sensor input 1, the display will
show “01 SD1” to indicate the last shutdown. Shutdown #1 was sensor
input #1. Press the “Up” key for “Shutdown 2”, “3”, “4”, and for any present
“Alarm”. To view the elapsed time reading at which any of the shutdowns
occurred, press “Push To Read Hours” key while viewing that shutdown.
Class “B” Lockout Timer
Allows the system to become fully operational without shutting down by
start-up related conditions. Class “B1” and Class “B2” Sensor inputs are
locked out until their corresponding timer expires. Class “B1” Timer is selectable from 0:00-5:00 minutes, and Class “B2” Timer from 0:00-9:59 minutes.
Class “C” Functions
There is a practical limit of sensor inputs defined as Class “C” Shutdown
and/or Class “C” alarm of 8 points. The Class “C” function operation is that
the sensor will be initially faulted on Start-up. If the sensor never clears there
will not be any annunciation and alarm or shutdown. If the sensor clears for a
full 2 seconds, then it is armed to alarm or shutdown. Pressing the Reset key
will allow a Class “C” alarm function to go back to the Start-up state where it
can remain faulted without annunciation and alarm. An example of a Class
“C” function is Low Discharge pressure.
Ignition Ground Delay
The Reset key resets All faults and initiates the Class “B” timers.
This delay is selectable from 0-20 seconds. To select the delay use SETUP.4,
see User Set Up Menus and To Enter User Set Up on page 5.
Overspeed
Hourmeter
(-T models only)
These models feature an internal tachometer with Overspeed Shutdown
(50). This shutdown bypasses the Ignition Ground Delay. It is not
locked out by the Test Timer.
The TTDJ internal hourmeter keeps track of Run Hours. To display Run
Hours for 5 seconds, press the Push to Read key. Run Hours are stored
in non-volatile memory, maintaining hours in the absence of power.
Underspeed Annunciation
RS485 Serial Port
(-T models only)
TTDJ-IGN-T models display (51) when an underspeed condition occurs. It is
not locked out by the Test Timer.
Loss of Ignition Annunciation (non -T models)
The TTDJ-IGN models will display (51) when ignition input is lost. It is
not locked out by the Test Timer.
Run/Stop Key (Manual Stop)
The Manual Run/Stop key is used for system shutdown from the panel.
When pressed, the unit will shutdown the system without turning on the
Alarm Output (on -DC models the Alarm Output is turned off on Manual
Stop). Manual Stop (Shutdown 52) is not locked out by the Test Timer.
Low Backup Battery Voltage
(-IGN models)
The TTDJ-IGN models have an internal backup battery. When the
“Lowbatt” display appears (this message will alternate with other displays) the battery needs to be replaced, see page 3 for details.
Timer “O” Key
This key zeros the current displayed timer: Class “B1”, “B2”, Ignition
Ground Timer, or Test Timer. If the TTDJ is in the Test mode, it exits Test.
Test Key
Initiates the Test Timer with 5 minutes. Test mode is indicated by the “3” in
the first digit of the display. Faulted inputs are displayed as in normal operation, but the system is not shutdown and the Alarm Output is not turned on.
Press “Reset” to reset the fault and press the Timer “O” to exit. The following shutdowns override Test: Emergency Shutdown (32), Overspeed (50),
Manual Stop (52), Underspeed (51), Loss of Ignition (51) and Optional
Additional ESD if chosen as ESD. If Class “C” functions are used, they will
need to be bypassed to test other sensors. When exiting “Test” with Class
“C” functions, press “Reset” and “Timer 0” simultaneously.

Shutdown History
(TTDJ-DC / TTDJ-DC-T)
The RS485 serial port (MODBUS RTU slave) on the back of the module is
provided for communicating with micro-controllers, PC’s, PLC’s and
SCADA systems (see RS485 Typical Connections, below). It is recommended that a termination resistor** (customer supplied) be used on the
first and last device connected in a daisy-chain configuration.
The communication parameters are 9600 baud, no parity, 8 bits with 1 stop
bit (9600,N,8,1), half-duplex. The shield terminal on the TTDJ terminal
block should only be used if the drain wire on the shielded cable is not connected to ground anywhere else. Each device must have a unique RTU node
number. A retry delay of 0.3 second may be helpful (set up for 3 retries).
The TTDJ models store the last 4 shutdown codes and any alarm present

ignition for engine operation. Apply starting power to the engine.
Engine Speed (-T Models Only)
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.
Class “B1” Timer
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”.
Class “B2” Timer
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.
Elapsed Time
To display the run hours, press the “Display Hours” 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.
Alarm Only Condition
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 display and to turn OFF the Alarm output.
Overspeed (-T Models Only)
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.
Underspeed (-T Models Only)
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.
Manual Stop
To manually shutdown the engine, press the STOP/RUN key. The TTDJ will
shutdown the system and the display will indicate “52”. Manual Stop overrides the Test mode.
Ignition Ground Delay
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”.
Loss of Ignition
TTDJ-IGN models annunciate/display “51” when ignition input is lost.
The energy stored in the FV+ circuit will trip the fuel valve.
Resetting Shutdown Fault
After the shutdown condition is cleared on the equipment, press RESET key.
Test Timer
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 number 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”..
Test Mode Display
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
