Description C 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. Modbus Integer Holding Registers 40001= RPM 40002= ETM (elapsed Time Meter 0-65535 Hrs.) 40003= Class B1 (in seconds) 40004= Shutdown Numbers (0=OK) (1-32, 50-52 =SD shutdown) 40005= Output Status (Bit 0= IGN, Bit 1= FV, Bit 2= ALR) 40006= Inputs 1-16 (Bit 0 = TB1..., Bit 15= TB16) (True 1= Inactive) 40007= Inputs 17-32 (Bit 0= TB17.., Bit 15= TB32) (True 1= Inactive) If 40006 and 40007 both contain “FF” there are no active shutdowns. RS485 typical connections TTDJ #N+1 RTU Node #N+1 A** B SHD TTDJ #2 RTU Node #3 A** B SHD 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).

TTDJ-99062N page 7 of 8 †Alarm Before Shutdown is a function that causes annunciation and the alarm output, but will not cause a shutdown. SEQUENCE OF OPERATIONS System Start Up Press the RESET key to clear any faulted sensor input and unground/enable 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.
