Proof Failure
ProofFail Alarm
OilFailStpt: 9
OilFailDly: 120S
AutoRestarts: 0
Proof Fail
The ProofFail field determines whether the
E2 or Einstein will generate an alarm or notice
when a compressor proof failure occurs. Choose
either Alarm or Notice in this field.
Oil Failure Setpoint
If you chose Pressure as the Oil Failure
Type, the Oil Failure Setpoint is the pressure that
indicates a low oil condition in the compressor.
When the oil pressure falls below this setpoint, a
compressor oil failure alarm will be generated.
Oil Failure Delay
The Oil Failure Delay is the amount of time
an analog oil pressure transducer must be below
the setpoint, or a digital pressure switch must be
in the fail state before the CUB will shut off the
compressor.
Auto Restarts
If you chose Pressure as the Oil Failure
Type, the Auto Resets field sets the number of
times the CUB will attempt to reset the oil fail-
ure by turning the compressor OFF and then ON.
If the oil sensor still registers a failure after all
retries have occurred, the CUB will consider the
compressor failed and will not attempt another
reset.
Enter a number of retries per hour from 0-2.

Oil Restart Delay
OilRestDly: 0 M
OilFailRun: NO
OilFailType
: None
Oil Reset Delay
The Restart Delay is the amount of time the
CUB will wait between retry attempts. Enter the
desired restart delay in minutes:seconds (M:SS)
format.

Oil Failure Run
This field determines whether the CUB will
continue to attempt to control the compressor as
normal even after an oil failure has occurred. If
this field is set to Yes, the CUB will turn the
compressor output ON and OFF as normal dur-
ing an oil failure. If set to No, the CUB will turn
the compressor OFF and will not reactivate it
until the oil failure has been reset.
Oil Failure Type
Choose the type of input device used to
check oil pressure on the condensing unit.
Choose Pressure if using an analog pressure
transducer, Digital if using a digital pressure
switch, or None if you do not wish to generate
oil failure alarms.
8.2.5.6.
Digital Oil Failure
DigitalOilFail
Fail State: CLSD
AutoRestarts: 0
Digital Oil Fail State
If you chose Digital as the Oil Failure Type,
the Oil Fail State is the state of the digital pres-
sure switch that indicates a low oil condition.
When the digital input transitions to this state, a
compressor oil failure alarm will be generated.
Dig. Auto Restarts
If you chose Digital as the Oil Failure Type,
the AutoRestarts field sets the number of times
the CUB will attempt to reset the oil failure by
turning the compressor OFF and then ON. If the
oil switch still registers a failure after all retries
have occurred, the CUB will consider the com-
pressor failed and will not attempt another
restart.
Enter a number of retries per hour from 0-2.
