Programming The CUB Using the E2 or Einstein Front Panel
The MultiFlex CUB E2/ Einstein Interface • 27
To begin programming a CUB, navigate to
the CUB Status Screen for the board you wish to
program (see
Section 7.2.
). For Einstein, press
followed by
to enter the Setup Editor.
For E2, press
.
7.3.1. Screen 1: General
Name
Enter a name for this CUB in the
Name
field.
Long Name
If desired, enter a 40-character description of
the CUB in the
Long Name
field.
Case Type
The
Case Type
field is used to assign default
setpoints for your circuit based on the case type.
There are 64 case types to choose from, each
with its own default temperature setpoint,
defrost type, and defrost times. A complete list
of case types is provided in
Appendix B: Case
Type Defaults on page 68
. Use the Look-Up
Table (
for Einstein,
for E2) to select a
case type.
Cntrl Strategy
Control Strategy determines whether the
compressor will be controlled by suction pres-
sure or suction temperature. Use the Look-Up
Table (
for Einstein,
for E2) to select
Pressure
or
Temperature
.
Cond Strategy
The Condenser Strategy determines whether
the condenser will be controlled by discharge
pressure (
Pressure
) or by temperature differen-
tial strategy (
TD
). Use the Look-Up Table (
for Einstein,
for E2) to select a strategy.
Refr Type
The
Refrigerant Type
field is where the
type of refrigerant being used in the condensing
unit system must be specified. The CUB uses the
Refrigerant Type
field to automatically calcu-
late saturation suction temperature. Use the
Look-Up Table (
for Einstein,
for E2)
to select a refrigerant type.
Oil Protection
If set to
ENABLE
, the
Oil Protection
field
specifies whether an oil failure sensing device is
present for the condensing unit. If an oil pressure
transducer is available, set this field to
ENABLE
. If oil pressure checking will not be
used for this CUB, set this field to
DISABLE
.
Comp Proof
The
Comp Proof
field specifies whether a
compressor proof checking device is present for
the condensing unit. If a compressor proof input
is available, set this field to
ENABLE
. If com-
pressor proof checking will not be used for this
CUB, set this field to
DISABLE
.
Phase Protect
The
Phase Protect
field specifies whether a
phase loss detection device is present for the
condensing unit. If a phase loss input is present,
set this field to
ENABLE
. If not, set this field to
DISABLE
.
Door Switch
The
Door Switch
field specifies whether a
door switch is present on the condensing unit’s
case circuit. If a door switch input is available,
set this field to
ENABLE
.
