DESCRIPTION: Use this screen to set the speci fi c Drive
safeties information for a constant speed electric drive
motor. These safeties are important for the safe operation
of the compressor and motor.
The information that appears on this screen will also be
repeated for most other types of motor drives. The fol-
lowing pull-down menus and setpoint boxes are shown
here. This information should be recorded from the motor
nameplate:
NAME PLATE
• [Motor Amps] – Enter the value from the
motor nameplate.
• [Volts] – Enter the value from the motor
nameplate.
• [Service Factor] - Not required if using
RAM DBS.
• [Horse Power] – Enter the value from the
motor nameplate.
• [CT Factor] - The Current Transformer Fac-
tor is printed on the current transformer in
the compressor motor starter. Note: Not re-
quired if using RAM DBS.
To verify that the CT has been sized
properly, use the following equation:
CTF = FLA (Full Load Amps) x Ser-
vice Factor x 1.1 = Recommended
CT (Round up to next highest 100
Amps)
EXAMPLE: FLA = 182 Amps
sF = 1.15
CTF = (182 x 1.15 x 1.1) = 230.23 >
Round up to 300 [use 300:5 CT]
• [Recycle Delay] - Each time the compres-
sor is started this value will be loaded into
the Recycle Delay timer. This time must
elapse prior to allowing the compressor to
restart. The timer will time out while the
compressor is running or stopped since the
Recycle Delay is a start-to-start protection.
The Recycle Delay time is intended to pre-
vent damage to the motor from successive
restarts.
NOTE: Consult Motor Manufacturer for the
recommended duration of the Recycle
Delay.
• [Clear Remaining Delay] – This selection
will clear the remaining delay time, allow-
ing the motor to be re-started immediately.
