TITLE
DESCRIPTION
Configurable Functions
−
Cd43 is a user-selectable function. The operator can change the value of this function to
meet the operational needs of the container.
Cd43 AutoFresh Mode
Cd43 is a user selectable mode of operation that allows opening and closing of a
mechanical air vent door via a stepper motor. 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 CO
2
and O
2
selectable limits
(LM). This selection is only active if the unit has a CO
2
sensor.
TEST / CAL (CO
2
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 CO
2
sensor input.
If the unit is not configured with AutoFresh, the CD43 will display “
−−−−
”
Display Only Function
−
Cd44 is a display only function.
Cd44 eAutoFresh Values /
CO
2
Sensor Status
Code Cd44 displays the eAutoFresh CO
2
and O
2
values (CO
2
and O
2
) and CO
2
and O
2
limits (CO
2
LIM
and O
2
LIM), respectively.
This function code will be dashed out if not configured for eAutofresh.
This function code will be dashed if CO
2
sensor is not detected, and a sensor is
not expected (didn’t have one previously).
This function code will display “ChECK” if a CO
2
sensor has not been auto
−
detec-
ted at the most recent power
−
up and was detected at a previous power
−
up. If
“ChECK” is displayed and the ENTER key is pressed, “SEnSr” is displayed with
the choices of “YES” and “no”:
“YES” – sensor should be remembered as detected (present)
“no” – sensor should not be remembered as being detected (not present)
Configurable Functions
−
Cd45 through Cd48 are user-selectable functions. The operator can change the value of
these functions to meet the operational needs of the container.
Cd45 Vent Position Sensor
(VPS) Position
Values: 0 to 240 for UPPER / 0 to 225 for LOWER
This function code will be dashed out if not configured for VPS.
When configured for VPS, Cd45 displays the current vent position in units of 5
CMH (units displayed as “CM”) or CFM (units displayed as “CF”) depending on
the selection of Cd46 (Airflow display units), Cd28 (Metric/Imperial) or the press-
ing of the deg C/F key.
Cd45 will display whenever the control detects movement via the sensor unless
AL50 is active. Cd45 will display for 30 seconds, then time out and return to the
normal display mode.
Cd46 Airflow Display Units
Selects the airflow units to be displayed by Cd45 if configured for Vent Position
Sensor or displayed by “USER/FLO” under Cd43 if configured for Autoslide.
CF= Cubic Feet per Minute
CM=Cubic Meters per Hour
bOth=Displays CF or CM depending on the setting of Cd28 (Metric/Imperial) or
the pressing of the degree C/F key.
Cd47 Variable Economy
Temperature Setting
The variable temperature “degrees C or degrees F” setting is used with economy
mode. Function code is “
−−−−
” when unit is not configured for economy mode.
