Pressing ENTER key will take the interface down into a hierarchy of parameter
selection menus in the order listed above. Pressing ENTER key in any of the
parameter selection menus selects the currently displayed parameter and causes
the interface to descend into the next parameter selection menu. All parameter
selection menus alternate between a blank display and the current selection in
the right hand display.
Pressing CODE SELECT key in a selection menu cancels the current selection
activity and ascends back up to the next higher selection menu (or to Cd53 dis-
play mode if that is the next higher).
If the operator does not press any key for five seconds the interface reverts to
normal system display and the current selection menu is cancelled, but any previ-
ously committed changes are retained.
Available parameters and parameter ranges are a function of configuration op-
tions and previously selected parameters as indicated above.
Parameter with the exception of “ASC” may not be altered if Cd53 is re

entered if
“ASC” is “On”. When ASC has completed including reaching the last setpoint
“done” on the left display and the MONTH DAY of completion on the right display
will be displayed as the second entry in the menu. Turning ASC off clears this
entry. This action also resets Cd53 to initial time remaining. ASC must then be
turned on to view or modify the additional parameters.
Whenever any auto Pretrip test or Trip Start is initiated, ASC mode goes to OFF.
Display Only Functions
−
Cd55 through Cd58 are display only functions.
Cd55 Discharge
Superheat
Cd55 will display the discharge superheat values in
C /
F as calculated by the
discharge temperature minus the discharge saturation temperature as calculated
from discharge pressure. “
−−−−−
” will be displayed if selection is not valid.
Cd58
Water Pressure
Switch / Condenser
Fan Switch State
Override Logic State
Cd58 will display “CLOSE” if the WPS or CFS switch contacts are closed or if
these options are not installed. “OPEn” is displayed when the WPS or CFS switch
contacts are open. When the WPS/CFS Override Logic is “TRUE”, the right dis-
play will flash on all units.
1. This CLOSE/OPEn state displayed in this Code Select function only applies to
units that have the ability to detect the state of a WPS/CFS. This function should
not be relied upon to display the condition of the switch on units that don’t have a
WPS/CFS switch connected to ECG2 exclusively.
2. The right display will flash if the WPS/CFS Override Logic is TRUE on all units.
This is always the case, whether the unit has a WPS or CFS installed or not.
3. The ability of the WPS/CFS Override Logic to control the condenser fan is limited.
It is not possible for this logic to control the fan on units that have the WPS or CFS
wired in series with the fan contactor. Units wired in this configuration can indicate
that the WPS/CFS Override Logic is active by flashing the right display, however,
the wiring will not allow for control of the condenser fan.
Configurable Functions
−
Cd60 is a user-selectable function. The operator can change the value of this function to
meet the operational needs of the container.
Cd60
Evaporator Fan
Pulsing Temperature
Setting
Cd60 contains a selectable temperature range used to determine the engage-
ment point of the Evaporator Fan Pulsing logic. Default setting is

C. The
user may change the temperature by pressing enter, then scrolling to the desired
temperature using either arrow key. Press Enter to accept the change. The tem-
perature setting will be retained until either a Pretrip or Trip Start is initiated at
which time the temperature will set to the default setting.
