WARNING!!! This may cause damage to the
compressor motor.
POWER OUTAGE RESTART
Restart Delay
- Will stagger the starting of
compressors after power is restored to prevent
multiple compressors from starting at the same
time.
• Disabled
• Enabled
• Time
Restart Lockout
- Prevents compressor from
starting after a power outage that lasts longer
than the setpoint.

MOTOR SAFETIES
High Motor Amps
(Considering a 1.15 SF)
:
•
[Load Inhibit]
- The compressor slide
valve will be prevented from loading
until the Motor Amps is less than this
setpoint.
TYPICAL SETTING: Motor Amps
Stop Load = FLA x 100%
•
[Force Unload]
- When the Motor
Amps is greater than or equal to this
setpoint, the compressor Slide Valve
will be forced to unload.
TYPICAL SETTING: Motor Amps
Force UnLoad = FLA x 105%
•
[Warning]
- If the Motor Amps is
greater than or equal to this setpoint,
for the warning time delay, a warning
occurs.
•
[Warning Delay]
- The minimum
time in seconds that the Motor
Amps is greater than or equal to
the High Motor Amps Warning
setpoint before noti
fi
cation of the
warning.
•
[Shutdown]
- If the Motor Amps is
greater than or equal to this setpoint,
for the shutdown time delay, the com-
pressor will shut down.
•
[Shutdown Delay]
- The minimum
time in seconds that the Motor
Amps is greater than or equal to
the High Motor Amps Shutdown
setpoint before the compressor
will shut down.
Low Motor Amps:
•
[Low Motor Amps Shutdown]
– This
setpoint is used to determine if the
coupling has broken. If the Motor Amps
is less than or equal to this setpoint, for
the shutdown time delay, the compres-
sor will shut down.
•
[Low Motor Amps Shutdown Delay]
–
The minimum time in seconds that the
Motor Amps is less than or equal to the
Low Motor Amps] Shutdown setpoint
before the compressor will shut down.
• [Con
fi
rmed Running Motor Amps]
–
The measured Motor Amps must be
greater than or equal to this setpoint
before the compressor will transition
from Starting to Running.
•
[Starting Motor Amps Ignore Period]
– After the compressor is commanded
to start, this setpoint indicates the pe-
riod during which the High Motor Amps
Load Inhibit and Force Unload checks
are not performed.
The following selection will allow the technician to manu-
ally energize, or bump, the compressor motor for the pur-
pose of determining motor rotation.
The following setpoint box has been provided:
•
Motor Bump Time
– Set this value to the
length of time that you wish to have the
compressor motor energized, or “bumped”.
The range is 0.0 to 15.0 seconds.
The following user selectable buttons are provided:
•
[Bump Motor]
– When this button is select-
ed, the compressor motor will be energized,
or “bumped” for the period of time as set in
the Motor Bump Time setpoint box.
