WARNING:

NOTE: The DD-40NTV annun-ciator may also be used with the 691200-1 Power Supply to emulate the function of the DD-40NTS system. For more detail, refer to Form DD-40NTS II 5-02.

Features designated by an * in these Installation Instructions are NOT available if using the 691200-1 Power Supply.

4.0 ANNUNCIATOR CONFIGURATION

4. The DD-40NTV series unit MUST be configured prior to use. If re-placinganolderseriesDDseriesannunciator,modes1and4canbeusedtodirectlyemulatetheoldersystem’sperformance.Mode1duplicates theoperationof theDD-40seriesandmode4dupli-cates the DD-20 series units. To configure the unit, press the MENUkey to reach the configuration headings from the normal display mode.Afteraselectionhasbeenmade,presstheENTERkeytosavetheselection.PressMENUtomovetothenextstep.Af lowchart(REFER TO FIG. 6A or 6B)isprovidedthatshowsstep-by-steppro-gression through the annunciator configuration procedure.

CAUTION:A. SENSOR WIRING: SENSOR WIRES WITHIN THE PANEL ENCLOSURE

MUST BE kEPT AT LEAST TWO (2) INCHES FROM OTHER WIRING. USE A SEPARATE JUNCTION BOx FOR IGNITION AND FUEL VALVE WIRES. RUN SENSOR LEADS LEAVING THE PANEL IN A CONDUIT SEPARATE FROM ALL OTHER WIRING AND kEEP SEPARATE THROUGHOUT THE INSTALLATION. WIRING TO THE SENSORS MUST HAVE A GRADE OF INSULATION CAPABLE OF WITHSTANDING AN AC VOLTAGE OF 500 V. RMS. SENSOR LEADS MAY BE CONNECTED TO ANY PASSIVE DEVICE USING CONTACTS SUCH AS STANDARD SWITCH GAUGES OR LEVEL SWITCHES. DO NOT CONNECT SENSOR LEADS TO RELAY CONTACTS OR TO ANY VOLTAGE PRODUCING ELEMENT.

B. SENSORS WILL BE ExPOSED TO MUCH LOWER VOLTAGES AND CURRENT THAN WITH THE STANDARD MURPHY TATTLETALE OR SIMILAR TYPE SYSTEM. IN THE CASE OF A FIELD CONVERSION WHERE SENSORS HAVE PREVIOUSLY BEEN USED WITH MURPHY TATTLETALES, IT IS RECOM-MENDED THAT THE SENSORS BE CHECkED FREqUENTLY WHEN THE DD SYSTEM IS FIRST PUT INTO USE. SENSOR CONTACTS MAY BE BURNED OR PITTED FROM PAST ExPOSURE TO IGNITION SYSTEM PRIMARY VOLT-AGE. IT IS ADVISABLE TO REPLACE SUCH SENSORS.

C. IF IT BECOMES NECESSARY TO CHECk SENSOR TO PANEL WIRING WITH

AN OHMMETER OR OTHER CHECkER, FIRST DISCONNECT THE PLUG-IN TERMINAL STRIPS FROM THE BACk OF THE ANNUNCIATOR UNIT. APPLY-ING VOLTAGE TO THE ANNUNCIATOR THROUGH THE SENSOR LEADS MAY DAMAGE THE DEVICE. IN ADDITION, THE AREA SHOULD BE TESTED AS NON-HAzARDOUS BEFORE SUCH TESTING COMMENCES.

6.0 OPERATION Seechartonnextpage.

NOTE: Two fault occurrences will override the TEST mode: manual STOP function [60] and OVERSPEED [70].



NOTE:

a.) TEST cannot be used until the start-up timer interval ends – [01] on the display.

b.) A display reading of [09] means the system output will not activate unless the STOP button is pushed.

c.) Do not leave a sensor number on the display after the last test; push the TEST button to get [09] on the display; then wait two minutes until [01] displays or select the CANCEL TIMERS feature.

d.) For a complete system test, allow the test timer interval to expire – display changes from [09] to [01] – then cause one sensor to fault and allow the sys-tem output to activate. This will test the entire sys-tem for correct operation upon a fault with minimal downtime.

6. OPERATING SEqUENCE MACHINE DISPLAY FUNCTION DESCRIPTION Down [10-57] Shutdown Shutdown caused by the fault number

indicated. Number will remain until fault is corrected and RESET button depressed.

[60] Shutdown Shutdown caused by depressing STOP button.

[70] Shutdown Shutdown caused by overspeed.

[71] Shutdown Shutdown caused by loss of RPM signal.

[72]* Shutdown Shutdown caused by underspeed. This is a Class C function which is armed when the setpoint is exceeded by 100 RPM.

[80] Shutdown Push TEST button when down, indicates battery is Ok.

[00] Reset Before starting machine, momentarily push the RESET button. A display of [00] indicates all Class A sensors are ready for start-up. Any number 10-57 indcates a faulted sensor that must be cleared before start-up.

[60] Engine Purge To purge engine prior to start, depress the STOP button, roll the engine to purge, then push the RESET button. Engine can then be started provided display reads [00].

Running [00] Start-up Start-up timers have Class B1 and B2 points disarmed. All Class A points are being monitored. Pushing the RESET button re-cycles the start-up timers. To cancel the start-up timers, press the ENTER key, followed by the DOWN key while still depressing the ENTER key.

[01] Normal All points are being monitored. The transi- tion from [00] to [01] indicates the end of

the last start-up timer interval.

[89] Test From [01] display, press and hold TEST button; indicates adequate operating voltage.

[09] Test Press and release TEST button – a timed test period is initiated for approximately two

minutes. As a sensor is faulted, its number is latched on the display (but the output is not activated). To move to the next point, firstclearthesensor,thenpushtheTEST button again. The display reverts to [09] until the next sensor is faulted. After the last test, push the TEST button to get [09] on the display; wait two minutes until [01] displays.

[01] Normal Test period has ended; all points are being monitored. DO NOT LEAVE MACHINE UN- LESS DISPLAY READS [01].

tion and cannot send and receive data at the same time overthesametwowiresmakingitahalfduplexsystem.Whenthemasterisinthetransmitmode,theslaveisinthereceivemodeandvisa-versa.

• ELECTRICAL OPERATING RANGE: RS-485 is a communications standard to satisfy the need for

multi-dropped systems that can operate at high speeds overlong distances. RS-485 uses a balanced differential pair ofwiresswitchingfrom0to5voltstocommunicatedata.RS-485drivers can handle common mode voltages from −7 to +12 volts withoutlossofdata,makingthemanexcellentchoiceforindus-trialenvironments.

• LOADING: RS-485 uses a balanced differential pair of wires switching

from 0 to 5 volts to communicate data. In situations wheremany units (99 max.) are connected together on a long run,voltage drop on the communications leads becomes a majorproblem. Voltage drops on the RS-485 minus lead appear asacommonmodevoltagetothereceivers.Whilethereceiversare rated to a maximum voltage difference of ±7 volts, −7V to +12V, a practical system should not have a voltage difference exceeding ±3 volts under normal conditions.
