7.6 SUPERVISOR II OUTPUT RELAYS

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.

7.7 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
motor from the control panel side, view the cou-
pling by looking through the air inlet duct on the
lower side of the adapter fan housing. The cou-
pling should be turning clockwise. If the reversed
rotation is noted, disconnect the power to the start-
er and exchange any two of the three power input
leads, then recheck rotation. A "Direction of Rota-
tion" decal is located on the motor and cooler
shroud to show proper motor/compressor rotation.
7.8 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 (re-
fer to Section 7.7).

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 au-
tomatic condensate removal.
Deluxe only --- used with sequencing feature.
3. Be sure that all preparations and checks de-
scribed in the Installation Section have been
made.
4. Open the shut ---off valve to the service line.
5. Check for possible leaks in piping.
7. 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 oper-
ating 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.
7.9 SUBSEQUENT START-- UP PROCEDURE
On subsequent start ---ups, check that the proper
level is visible in the fluid level sight glass and sim-
ply press "I" for manual or "
eration. When the compressor is running, observe
the various parameter displays.

7.10 SHUTDOWN PROCEDURE

To shut the compressor down, push "O" pad.
