RELAY
RUN RELAY (K1)
*--DELTA (K2)
UNLOAD/LOAD (K3)
COMMON FAULT (K4)
DRAIN VALVE (K5)
FULL LOAD/MODULATE (K6)
NOTE: All output relays will handle 8 amperes at 120/240 VAC.
6.8 MOTOR ROTATION CHECK
After the electrical installation has been done, it is
necessary to check the direction of motor rotation.
Pull out the EMERGENCY STOP button and press
once, quickly and in succession, the (START) "I"
and (STOP) "O" pads. This action will bump start the
motor for a very short time. When looking at the mo-
tor rear end, the driveline should be rotating in the
direction indicated by the "Direction of Rotation" de-
cal located on the top of the compressor/motor
adapter piece. If the reversed rotation is noted, dis-
connect the power to the starter and exchange any
two of the three power input leads, then re--check
rotation. A "Direction of Rotation" decal is located on
the top of the compressor/motor adaptor piece.
6.9 INITIAL START- -UP PROCEDURE
The following procedure should be used to make the
initial start--up of the compressor.
1. Read the preceding pages of this manual thor-
oughly.
2. Jog motor to check for correct rotation of fan.
3. Be sure that all preparations and checks de-
scribed in the Installation Section have been
made.
COMPRESSOR OPERATION
OPERATION
Contact closure energizes the compressor starter.
A timed contact used to provide Wye--delta transition
time.
Controls ON LOAD/OFF LOAD operation of the load
control solenoid valve.
May be used to provide remote indication of any pre--
alarm, maintenance or fault shutdown condition.
Deluxe only -- controls a solenoid valve to provide auto-
matic condensate removal.
Deluxe only -- used with sequencing feature.
4. Open the shut--off valve to the service line.
5. Check for possible leaks in piping.
6. Slowly close the shut--off valve to assure proper
nameplate pressure unload setting is correct.
The compressor will unload at nameplate pres-
sure. If adjustments are necessary, see Control
System Adjustments.
7. Observe the operating temperature. If the operat-
ing temperature exceeds 200_F (93_C), the
cooling system and installation environment
should be checked.
8. Open shut--off valve to the service line.
9. Reinspect the compressor for temperature and
leaks the following day.
6.10 SUBSEQUENT START- -UP PROCEDURE
On subsequent start--ups, check that the proper lev-
el is visible in the fluid level sight glass and simply
press "I" for manual or "
When the compressor is running, observe the vari-
ous parameter displays.
6.11 SHUTDOWN PROCEDURE
To shut the compressor down, push "O" pad.
