Programming The CUB Using the E2 or Einstein Front Panel
The MultiFlex CUB E2/ Einstein Interface • 35
Fan ON Dly
This parameter delays the amount of time the
CUB will wait after a defrost has ended before
turning on the evaporator fans. This delay is
designed to keep the fans from blowing moisture
off the coil and onto the case doors or walls.
Enter the desired delay in hours:minutes:seconds
(H:MM:SS).
Defrost Dur.
The Defrost Duration is the maximum
amount of time a defrost cycle will last. Unless it
is prematurely terminated by temperature or suc-
tion pressure, a defrost cycle will end when it
has been in defrost for an amount of time equal
to this field (not including any pump down or
drip delays).
Enter the desired Defrost Duration in hours
and minutes (HH:MM).
Min Defr Time
The Minimum Defrost Time sets the mini-
mum amount of time a defrost cycle will last. A
defrost cycle will always last at least as long as
this time, and will ignore all calls for defrost to
terminate until the Minimum Defrost Time has
elapsed.
Enter the desired Defrost Duration in hours
and minutes (HH:MM).
Drip Time
The Drip Time is a delay between the end of
defrost and the resuming of refrigeration to
allow excess moisture to drain from the evapora-
tor coil.
During the drip time, both the refrigeration
and defrost outputs will be OFF. When the drip
time has elapsed, refrigeration will resume in the
case circuit.
Enter the desired drip time, in minutes, in
this field.
Number of Defrost Schedules and Defrost Time
The Number of Defrost Schedules sets the
number of daily defrosts for this circuit. This
field is automatically filled in for you when you
select a case type in the
Case Type
field.
Enter a number from 1 through 12 in this
field. When you enter a number, the appropriate
number of Defrost Time fields will appear under
this field. Use these fields to enter the start times
for each daily defrost cycle.
Defr Temp Setpt
If you selected
Term Temp
,
Min Case
Temp
,
or
Case Temp 1-6
as the Termination
Type, the
Defr Temp Setpt
field will appear on
this screen. Enter the case temperature that,
when exceeded by the value of the termination
sensor, will cause defrost to terminate.
7.3.7. Screen 7: Outputs
Because the CUB has limited memory to log
inputs and outputs, and because it has no ability
to do customized advanced controls that may be
required by certain sites, the E2 or Einstein
makes all CUB input, output, and state values
available as outputs. This allows you to log CUB
inputs or outputs, to set up alarms for the CUB
outside of its own alarm control capabilities, and
to share CUB values with other E2 or Einstein
applications.
You will not need to use this screen at all
unless you are setting up advanced-level log-
ging, alarming, or controls that involve the CUB
inputs and outputs.
