IAW ASME Y14.5M--1994
3. SPECIFICATIONS, INCLUDING THOSE PERTAINING
TO FORM, FIT, FUNCTION, FINISH, RELIABILITY
OR DURABILITY, SHALL BE EQUAL TO OR BETTER
THAN THOSE REQUIRED FOR THE ORIGINAL ITEM
APPROVED BY INGERSOLL--RAND COMPANY.
4. SPECIFICATIONS:
4.1 LOCATION OF CONTROLS AND COMPRESSOR INTERFACE
THE AUTOSTART/STOP CONTROLS (ASSC) SHOULD BE LOCATED NEXT TO THE
COMPRESSOR MAIN CONTROL PANEL, AND INTERFACE CONNECTIONS SHOULD BE
MADE BY UTILIZING THE EXISTING HARNESS CONNECTORS AS PICKUP POINTS.
ASSC MATING CONNECTORS OR TERMINALS MUST BE COMPATIBLE WITH EXISTING
COMPRESSOR CONNECTORS.
4.2 PHYSICAL AND ENVIRONMENTAL DESIGN
THE ASSC MUST BE SUITABLE FOR OPERATION IN A DIESEL ENGINE COMPARTMENT
FROM --20 F TO +140 F AMBIENT TEMPERATURE.
THE ASSC MUST BE HOUSED IN A NEMA 12 ENCLOSURE THAT CAN BE READILY
OPENED AND CLOSED. ANY CMOS, MOS, OR OTHER ELECTRONIC OR SENSITIVE
COMPONENTS MUST BE CONFORMALLY COATED OR OTHERWISE PROTECTED FROM
AIRBORNE CONTAMINANTS AND HUMIDITY.
REFER TO THE LAYOUT DRAWING FOR PHYSICAL DIMENSIONS, MOUNTING, AND
WIRING REQUIREMENTS.
4.3 CIRCUIT PROTECTION
THE ASSC MUST BE PROTECTED BY AN OVERCURRENT DEVICE.
4.4 OPERATION SEQUENCE -- AUTOMATIC MODE
WHEN THE SELECTOR SWITCH INSIDE THE ASSC BOX IS TURNED TO THE
”AUTOMATIC” POSITION AND THE SWITCH ON THE COMPRESSOR MAIN CONTROL
PANEL IS TURNED ON,THE AUTO MODE LIGHT WILL BE ACTIVATED AND THE UNIT
WILL OPERATE AS FOLLOWS:
A-- THE ASSC WILL REMAIN IN A STANDBY CONDITION WITH THE COMPRESSOR
OFF UNTIL THE PRESSURE OR OTHER TRANSFER SWITCH (INSTALLED BY THE
CUSTOMER) CONTACTS CLOSE. WHEN THE SWITCH CLOSES, THE ASSC WILL
PROCEED AS FOLLOWS:
B-- DURING AN INITIAL FIXED DELAY OF 10 SECONDS, A ”PULSED” ALARM WILL
SOUND AND THE UNLOADER COMPRESSOR MOTOR WILL BE ACTIVATED. THE
INITIAL DELAY ALSO PROTECTS AGAINST SHORT TERM RIPPLES IN THE MAIN
AIR SUPPLY.
C-- AFTER THE INITIAL ALARM DELAY, THE UNIT WILL BEGIN ITS NORMAL
CRANK CYCLE. CONCURRENT WITH THE START OF EACH CRANK, A 2 SECOND
PULSED OUTPUT MUST BE PROVIDED FOR ETHER INJECTION. IMMEDIATELY
PRIOR TO CRANK, THE START/RUN VALVE MUST BE ENERGIZED AND REMAIN
SO UNTIL THE COMPRESSOR IS LOADED (STEP G). THE UNLOADER COMPRES--
SOR MOTOR MUST REMAIN ACTIVATED DURING CRANK. AN ADDITIONAL
DRY CONTACT MUST BE INSERTED IN SERIES WITH THE HEATER SWITCH
(S11) AND CLOSE ONLY DURING UNIT STARTING AND RUN OPERATION. THE
DRY CONTACT WILL BE ENERGIZED TO AN OPEN STATE DURING STANDBY AND
DEFAULT TO CLOSED UPON LOSS OF POWER OR MANUAL MODE OPERATION.
D-- THE CRANK PERIOD SHOULD BE ADJUSTABLE FROM 4 -- 30 SECONDS
(FACTORY PRESET TO 10 SECONDS). THE REST PERIOD SHOULD BE ADJUSTABLE
FROM 10 -- 60 SECONDS (FACTORY PRESET TO 25 SECONDS). THE NUMBER OF CRANK
CYCLES SHOULD BE SETTABLE FOR 1 -- 5 CYCLES (FACTORY PRESET TO 3 CYCLES).
IF THE UNIT FAILS TO START AFTER THE SET NUMBER OF CYCLES, AN OVERCRANK
CONDITION SHOULD BE INDICATED AND A CONTINUOUS ALARM WILL SOUND.
THE ASSC WILL NOT ATTEMPT TO START AGAIN UNLESS POWER IS RECYCLED
OR A RESET BUTTON IS PUSHED.
