Enter the desired number of resets in this
field.
Proof Adv Type
The Proof Advisory Type allows you to set
the kind of advisory generated when a compres-
sor proof has failed. Choose
Alarm
if you want
to generate an alarm, or
Notice
if you want to
generate a notice.
7.3.10.5. Phase Fail Shutdown
If a phase loss detection device is available,
the CUB can shut down all systems when a
phase loss is detected.
Phase Fail Act
The Phase Fail Active State tells the CUB
what digital state from the phase loss checking
device signifies a phase failure. Set this field to
CLOSED
if the phase loss device closes its con-
tacts on a phase failure, or
OPEN
if it opens
contacts.
Phase Adv Type
When a phase loss occurs, the CUB will gen-
erate either an alarm or a notice, depending on
the value of this field.
7.3.10.6. Door Switch Alarms
If a door switch is available, the CUB can be
programmed to generate alarms to indicate an
open freezer door.
Door Sw State
The Door Switch Active State specifies
whether an open door causes the door switch to
be OPEN or CLOSED. Choose the door switch
state that corresponds to “door open” in this
field.
Door Sw Time
After the door has been opened, the CUB
records how long the door remains open. If it
remains open longer than the Door Switch Time,
the CUB will assume the door is stuck open and
will restart refrigeration to prevent food loss.
Enter the desired fail-safe time in hours:minutes
(H:MM) format.
Door Sw Alm Tm
After the door has been opened, the CUB
records how long the door remains open. If it
remains open longer than the Door Switch
Alarm Time, the CUB will generate a door open
alarm. Enter the desired alarm setpoint in
hours:minutes (H:MM) format.
7.3.10.7. Wash Active Alarms
If a clean switch is present on the condensing
unit’s case circuit, you can program the CUB to
generate an alarm if the system has been in Wash
mode for too long.
Wash Sw State
The Wash Switch Active State specifies
whether an OPEN or a CLOSED contact on the
clean switch indicates “enter wash mode.”
Choose either
OPEN
or
CLOSED
in this field.
Wash Sw Time
The Wash Switch Fail-Safe Time allows you
to suspend Wash mode and resume refrigeration
if Wash mode lasts longer than a fixed amount of
time. Enter the desired Wash Fail-Safe time in
hours:minutes (H:MM) format, or 0:00 if you do
not wish to use this feature.
7.3.10.8. Case Temperature Alarms
The CUB will generate alarms when the case
temperature is too high or too low.
Case Temp High
The Case Temp High Setpoint is the temper-
ature at which a high case temperature alarm
will be generated.
Case Tmp Dly
The Case Temp High Setpoint Delay is the
amount of time the case temperature must be
above the high case temp setpoint before an
alarm will be generated.
