MICRO-ELECTRIC STARTER FOR A.H.U.

THE “MICRO-ELECTRIC CONTROLLER” IS A MICRO CONTROLLER BASED ELECTRICAL DEVICE. THIS DEVICE IS USED TO OPERATE AND CONTROL THE A.H.U. AND A.H.U. WITH O.D.U.

BASICALLY TWO TYPES OF THE CONTROLLERS ARE AVAILABLE WITH FOLLOWING FEATURES.

NORMAL MICRO-ELECTRIC CONTROLLER (FOR A.H.U. ONLY).

• THE CONTROLLER IS ASSEMBLED IN A POWDER COATED, WALL MOUNTING TYPE MATELLIC ENCLOSER. (L /Ht.:13, W:12 & D:4.25 INCHES).
• THE INCOMING 3 PHASE POWER SUPPLY (R,Y,B & NEU.) IS PROVIDING THROUGH THE IN–BUILT 4 POLE M.C.B.
• RED, YELLOW & BLUE L.E.D. (10mm) INDICATORS ARE USED TO DISPLAY 3 PHASES.
• “START” (PUSH TO ON) SWITCH WITH “UNIT–ON” (RED L.E.D.) INDICATOR.
• “STOP” (PUSH TO OFF) SWITCH WITH “UNIT–OFF” (GREEN L.E.D.) INDICATOR.
• FACILITY TO CONNECT THE DEVICE WITH FIRE CONTROLLER.
• IN-BUILT “PHASE MONITOR / PREVENTOR” TO PROTECT 3 PHASE INDUCTIVE LOAD DURING ABNORMAL POWER CONDITION. SEPARATE INDICATORS FOR HEALTHY POWER, PHASE LOSS / MISSING & REVERSE PHASE SEQUENCE ARE PROVIDED.
• FITTED WITH “MEMORY” ON / OFF SWITCH. WHEN SWITCH IS SET AT ON POSITION, AND POWER BECOMES CUT–OFF, THE CONTROLLER REMEMBERS THE LAST STATUS OF THE DEVICE TILL POWER RE–GAIN. IF SWITCH IS SET AT OFF POSITION, CONTROLLER DOES NOT REMEMBER ANY STATUS AND KEEPS THE DEVICE AT STAND–BY MODE AFTER POWER RE–GAIN. THE USER WILL HAVE TO PUSH THE START BUTTON TO SWITCH ON THE DEVICE AGAIN.
• THE A.H.U. CONNECTS WITH THE DEVICE THROUGH IN–BUILT 3 POLE CONTACTOR.
• THE TAFLON COATED WIRES ARE USED IN LOAD LINES, IN SIDE THE DEVICE.
• IN–BUILT SAFETY FOR THE COIL OF CONTACTOR, AGAINST BURNING CASES AT OVER VOLTAGE.
• DEVICE IS FITTED WITH DIGITAL CURRENT METER TO DISPLAY RUNNING CURRENT.
• AND DIGITAL VOLT METER TO DISPLAY SUPPLY VOLTAGE.
• REMOTE OPERATION FACILITY IS ALSO PROVIDED.

TEMPERATURE CONTROLLED MICRO-ELECTRIC CONTROLLER (FOR A.H.U.WITH O.D.U.).

• THE CONTROLLER IS ASSEMBLED IN A POWDER COATED, WALL MOUNTING TYPE MATELLIC ENCLOSER. (L /Ht.:13, W:12 & D:4.25 INCHES).
• THE INCOMING 3 PHASE POWER SUPPLY (R,Y,B & NEU.) IS PROVIDING THROUGH THE IN–BUILT 4 POLE M.C.B.
• RED, YELLOW & BLUE L.E.D. (10mm) INDICATORS ARE USED TO DISPLAY 3 PHASES.
• “START” (PUSH TO ON) SWITCH WITH “UNIT–ON” (RED L.E.D.) INDICATOR.
• “STOP” (PUSH TO OFF) SWITCH WITH “UNIT–OFF” (GREEN L.E.D.) INDICATOR.
• FACILITY TO CONNECT THE DEVICE WITH FIRE CONTROLLER.
• IN-BUILT “PHASE MONITOR / PREVENTOR” TO PROTECT 3 PHASE INDUCTIVE LOAD DURING ABNORMAL POWER CONDITION. SEPARATE INDICATORS FOR HEALTHY POWER, PHASE LOSS / MISSING & REVERSE PHASE SEQUENCE ARE PROVIDED.
• FITTED WITH “MEMORY” ON / OFF SWITCH. WHEN SWITCH IS SET AT ON POSITION, AND POWER BECOMES CUT–OFF, THE CONTROLLER REMEMBERS THE LAST STATUS OF THE DEVICE TILL POWER RE–GAIN. IF SWITCH IS SET AT OFF POSITION, CONTROLLER DOES NOT REMEMBER ANY STATUS AND KEEPS THE DEVICE AT STAND–BY MODE AFTER POWER RE–GAIN. THE USER WILL HAVE TO PUSH THE START BUTTON TO SWITCH ON THE DEVICE AGAIN.
• THE A.H.U. AND THE O.D.U. CONNECTS WITH THE DEVICE THROUGH IN–BUILT 3 POLE CONTACTORS.
• THE TAFLON COATED WIRES ARE USED IN LOAD LINES, IN SIDE THE DEVICE.
• IN–BUILT SAFETY FOR THE COIL OF CONTACTOR, AGAINST BURNING CASES AT OVER VOLTAGE.
• 2 DIGITS, DIGITAL TEMPERATURE MONITOR AND CONTROLLER IS USED TO PROGRAM THE O.D.U. AT DESIRE ROOM TEMPERATURE. USER CAN PROGRAM IN THE RANGE, FROM 16 TO 30 DEG. CELCIOUS.
• PROGRAM SWITCH (PUSH TO ON):- TO ENTER IN TO & EXIT FROM PROGRAMING MODE, TO SET DESIRE ROOM TEMPERATURE VALUE.
• VALUE SWITCH (PUSH TO ON):- TO SET THE DESIRE TEMPERATURE VALUE IN SCROLLING WAY. THIS SWITCH ALSO USE TO LOCK (AFTER DESIRE TEMPERATURE SETTING) & UN-LOCK (BEFORE DESIRE TEMPERATURE SETTING) THE KEY BOARD. THE SEVEN SEGMENT DISPLAY SHOWS “LO” WHEN LOCKED AND “UL” WHEN UN-LOCKED. KEEP PRESS THIS SWITCH TILL >5 SECONDS TO AVAIL THIS FEATURE.
• HP / LP PROTECTION FEATURE IS ALSO IN THE DEVICE WITH L.E.D. INDICATION. THIS L.E.D. FLASHES WHEN H.P. OR L.P. CONDITION OCCURS.
• COMPRESSOR STARS WITH APPROXIMATELY 3 MINUTES ON–DELAY.
• ALL SAFETIES ARE AUTO RE–SETABLE.
