Under/Over Voltage Protection Enable
This screen does not appear if the Line Voltage
Sensing Option is not installed or Compressor Power
Source is Engine/Generator.
Line voltage above + 10% of nominal. (Must hold = +
10 % of nominal. Must trip = + 15 % of nominal.
Reset differential = min. of 2% and max. of 4%. Time
to trip = minimum of 1 min. 10 sec. and maximum of
5 min. 20 seconds).
Possible values of [d/e] are: Disable (Factory
Default) and Enable.
Note: Under/Over Voltage Protection is activated
only if Under/Over Voltage Protection is enable and
Line Voltage Sensing Option is Installed.
Phase Reversal Protection Enable
This screen does not appear if the starter type is
“Adaptive Frequency” or “AFDB.”
Possible values of [d/e] are: Disable and Enable
(Factory Default).
A phase reversal is detected on the incoming current.
On a compressor startup, the phase reversal logic
must detect and trip in 0.7 seconds.
Phase Unbalance Limit Enable
Possible values of [d/e] are: Disable and Enable
(Factory Default).
The RLA of the motor is derated by resetting the
active current limit. The trip point is a 30% phase
unbalance for 90 seconds.
Momentary Power Loss (MPL) Protection
Enable
This screen does not appear if the starter type is
“Adaptive Frequency” or “AFDB.” or Compressor
Power Source is Engine/Generator.
Possible values of [d/e] are: Disable and Enable
(Factory Default).
For MPL, on every power down, the reset inhibit
timer is reset to 30 seconds if the motor temperature
is <165°F and 15 minutes if the motor temperature is
> or = to 165°F.
Enhanced Oil Temp. Protection
This screen does not appear if the starter type is
“Adaptive Frequency” or “AFDB.
When enhanced oil protection is enabled, the oil
heater relay is energized at 140.5ºF (60.3ºC) and de-
energized at 145.5ºF (63.1ºC). The low oil
temperature cutout “setpoint” is equal to the
saturated evaporator refrigerant temperature plus
30ºF (16.6ºC) or 100 ºF (37.8ºC) which ever is
larger.”
Possible options are: Disable and Enable (Factory
Default).
Oil Temp Setpoint
This screen does not appear when Enhanced Oil
Temperature Protection is enabled.
The range of values is 100°F to 160°F (37.8 to
71.1°C) in increments of 1 or 0.1°F or °C, depending
