FUNCTION

M2-8 is a Programmable fault Annunciator having features like programming input fault for window annunciating w.r.t NO or NC, output relay for either TRIP or ALARM function.

Terminals Details:

A1, A2 : Source voltage PGM ENABLE : Short -Program Enable Open- Program Disable COM : Common fault terminal MUTE, ACK, RST, TEST : For External push buttons, Remote operations and cascading facility. Connect WRT COM(No Volt) F1 to F8: Individual fault I/P terminals for respective window Connect WRT COM(No Volt)

Front Panel Switches.

SEL : To select the window for programming in PGM mode MUTE : To mute the relay during fault conditions in RUN mode NC/NO : Select NC or NO as input sensing in PGM Mode ACK : To Acknowledge the fault during fault conditions in RUN Mode RST : To reset the fault, once fault is rectified in RUN mode T/NT : Select Trip Relay or Alarm Relay in PGM mode TEST : To test healthy condition of all windows in RUN mode

Testing of windows for working condition

1) Apply source voltage between A1 & A2 2) Remove the short between P1 & P2 to operate in RUN mode. 3) Slide the RUN/PGM switch to PGM mode.

Press

4) Test Button - All windows starts flashing and relay switches on.(Trip / Alarm)

5) Mute Button - Relay switches OFF (Trip / Alarm)

6) ACK Button - Flashing window becomes steady to acknowledge the fault

7) RST Button - Window switches OFF indicating fault is rectified.

Sequence of operation:

PROGRAMMING

Short “PGM ENABLE” terminals at the rear using wire jumper. Slide the RUN / PGM switch to PGM Mode. Press SEL button, window 1 will glow. By pressing NC/NO button, the Red LED can be toggled from ON to OFF and vice versa. If the RED LED glows. Normally open is a healthy condition & fault sensing is closed type. If RED LED is OFF Normally closed is a healthy condition & fault sensing is open type. By pressing T/NT button, the GREEN LED can be toggled from ON to OFF and vice versa. If the GREEN LED glows the output is programmed for ALARM RELAY and if the GREEN LED is OFF the output programmed is for TRIP RELAY. Press SEL button, now the second window shall glow and by pressing the NC/NO and T/NT buttons required fault input sensing and relay output can be programmed. Follow the above procedure for the rest of the windows. Once the programming of all the windows is over, remove short at “PGM ENABLE” terminals, to save the program Slide the RUN / PROG switch to RUN Mode.

HINTS ON CORRECT USAGE

� Use proper gauge wires for connections. � Ensure all terminals are tightly screwed. � Source Voltage should not exceed specified limits. It will damage the

unit beyond repair.

CAUTION

� Applying power to “PGM ENABLE”, MUTE, ACK, RST, TEST & F1-F8 shall damage the product permanently.

� Blinking of unit indicates over

voltage. Switch off the unit for 20Sec to reset the resetable fuse & switch on.

Applicable for Aux supply 85 to 270V AC/DC only

DISPOSITION

� Once the product life is over, you may send back the unit to EAPL for disposition.

TROUBLE ANALYSIS

� Pilot LED not blinking. Check power supply (Rated supply should be applied).

� Fault not sensing. Check for proper connection between Common & fault terminals (F1-F8).
