Table 6 Controller Function Codes (Sheet 4 of 4)
Display Only Functions -- Continued
Cd38 Secondary Supply
Temperature Sensor
Code Cd38 will display the current secondary supply temperature sensor reading
for units configured for four probes. If the unit is configured with a DataCORDER,
Cd38 will display “
-- -- -- -- --
.” If the DataCORDER suffers a failure, (AL55) Cd38
will display the supply recorder sensor reading.
Cd39 Secondary Return
Temperature Sensor
Code Cd39 will display the current secondary return temperature sensor reading
for units configured for four probes. If the unit is configured with a DataCORDER,
Cd39 will display “
-- -- -- -- --
.” If the DataCORDER suffers a failure, (AL55) Cd39
will display the return recorder sensor reading.
Cd40 Container Identifica-
tion Number
Code Cd40 is configured at commissioning to read a valid container identification
number. The reading will not display alpha characters, only the numeric portion of
the number will display.
Cd41
Cd42 Not Applicable
Scroll Units Only
The following Configuration Codes (Cd43--45) highlighted in gray apply to Software Revisions
5123 and 5124 ONLY.
Cd43 Air Slide Mode
This code is only applicable to units with Auto Fresh. If not configured, the mode
is permanently deactivated and CD 43 will display “-- -- -- -- --”. When mode is
available, it can be set to “OFF”, “AUTO”, “USER”, or “TEST”. After “AUTO” or
“USER” mode has been selected and entered, the user may use function code 45
and 46 to make desired changes.
Cd44 Air Slide Opening
This code is only applicable to units with Auto Fresh. If not configured, the per-
cent opening is permanently deactivated and Cd44 will display
”-- -- -- -- -- “. When percent opening is available, it can be set to 0% to 100%.
Cd45 Air Slide Timer
This code is enabled only if Air Slide Mode is “AUTO” or “USER”. If not, Cd45 will
display “-- -- -- -- --”.
In software revision 5125, Codes Cd43--Cd45 were consolidated into Code Cd43,
and Codes Cd44--Cd45 were reassigned.
Cd43 AutoFresh Mode
Code Cd43 is a user selectable mode of operation that allows the opening and
closing of a mechanical air vent door via a stepper motor. These selection modes
are as follows:
OFF -- Air makeup vent will remain closed.
User -- Allows for manual selection of the setting.
Delay --The opening of the door is based on selected time, return temperature
and flow rate (percent opened).
gASLM -- The opening is based percent open and CO2 and O2 selectable limits
(LM). This selection is only active if the unit has a CO2 sensor.
TEST/ CAL (CO2 sensor option units only) --
The door will fully open and
close to allow the user to
inspect its operation. If CAL is
selected the controller will zero
calibrate the CO2 sensor input.
If the unit is not configured with AutoFresh the CD43 will display “--------”.
Cd44 AutoFresh Values
Code Cd44 will display CO2 and O2 concentrations and limits. If the unit is not
configured for AutoFresh or a CO2 sensor is not installed , CD44 will dis-
play“--------” .
Cd45 Vent Position Sensor
(VPS)
Code Cd45 will display whenever the control detects movement via the sensor
unless alarm 50 is active. The code will display for 30 seconds, then time out and
return to the normal display mode. If the Temperature unit is
_
F, the VPS units will
be CFM and in
_
C the VPS units shall be CMH.
Cd46 Not Used
--
Cd47 Variable Economy
Temperature Setting
The variable temperature “
_
C or
_
F” setting is used with economy mode. Func-
tion code is “--------“ when unit is not configured for economy mode.
Cd48
Dehumidification/
Bulb Mode
Parameter Selection
Code CD48 is used to determine limits (between 60%--95%) for dehumidification
and/or bulb mode (CNF28) when active.
Cd49 Days Since Last
Successful Pre--Trip
Code CD49 will display the number of days since the last successful Auto1,
Auto2 or Auto3 pre--trip sequence.
