- AL66Error codeSuction Pressure Transducer (SPT) out of range
- AL67Error codeHumidity Sensor (HS) reading out of range
- AL68Error codeCondenser Pressure Transducer (CPC) out of range
- AL69Error codeSuction Temperature Sensor (CPSS) out of range
- AL70Error codeSecondary Supply Sensor (SRS) is out of range
- AL71Error codeSecondary Return Sensor (RRS) is out of range
- AL72Error codeAfter the unit goes in- range for 30 minutes then out of range for a continuous 120 min- utes
- Cd01Error codeDisplays the SMV percent open. The right display reads 100% when the valve is fully open and 0% when the valve is fully closed. The valve will usually be at 21% on start up of the unit except in very high ambient temperatures
- Cd02Error code
- Cd03Error code
- Cd04Error codeThe current sensor measures current on two legs. The third unmeasured leg is calcu- lated based on a current algorithm. The current measured is used for control and diag- nostic purposes. For control processing, the highest of the Phase A and B current values is used for cur- rent limiting purposes. For diagnostic processing, the current draws are used to mon- itor component energization. Whenever a heater or a motor is turned ON or OFF, the current draw increase/reduc- tion for that activity is measured. The current draw is then tested to determine if it falls within the expected range of values for the component. Failure of this test will result in a pretrip failure or a control alarm indication
- Cd07Error codeThe main supply voltage is displayed
- Cd08Error codeThe value of the main power frequency is displayed in Hertz. The frequency displayed will be halved if either fuse F1 or F2 is bad (see alarm code AL21)
- Cd09Error codeThe Ambient Temperature Sensor reading is displayed
- Cd10Error codeThe Compressor Suction Temperature Sensor reading is displayed
- Cd11Error codeThe Compressor Discharge Temperature Sensor reading is displayed
- Cd12Error codeThe Compressor Suction Pressure Transducer reading is displayed
- Cd13Error codeThe Condenser Pressure Control Sensor reading is displayed
- Cd14Error codeThe Compressor Discharge Pressure Transducer reading is displayed
- Cd17Error codeHumidity sensor reading is displayed. This code displays the relative humidity, as a percent value
- Cd19Error codeThis code checks the Controller/DataCORDER battery pack. While the test is running, “btest” will flash on the right display, followed by the result. PASS will be displayed for battery voltages greater than 7.0 volts. FAIL will be displayed for battery voltages be- tween 4.5 and 7.0 volts, and ----- will be displayed for battery voltages less than 4.5 volts. After the result is displayed for four seconds, “btest” will again be displayed, and the user may continue to scroll through the various codes
- Cd21Error codeThis code displays the status of the humidity water pump (-----, FWD, REV or OFF). If not configured, the mode is permanently deactivated and will display -----
- Cd23Error codeDisplays the current evaporator fan state (high, low or off)
- Cd26Error codeDefrost Temperature Sensor (DTS) reading is displayed
- Cd27Error codeThere are two modes for defrost initiation, either user-selected timed intervals or auto- matic control. The user-selected values are (OFF), 3, 6, 9, 12, 24 hours, AUTO, or PuLS. Factory default is 3 hours. Automatic defrost starts with an initial defrost at three hours and then adjusts the inter- val to the next defrost based on the accumulation of ice on the evaporator coil. Follow- ing a startup or after termination of a defrost, the time will not begin counting down until the defrost temperature sensor (DTS) reading falls below set point. If the reading of DTS rises above set point any time during the timer count down, the interval is reset and the countdown begins over. If the DTS fails, alarm code AL60 is activated and control switches over to the return temperature sensor. The controller will act in the same manner as with the DTS except the return temperature sensor reading will be used. If CnF23 is configured to “SAv” (save), then the value of the defrost interval timer will be saved at power down and restored at power up. NOTE The
- Cd28ParameterThis code determines the temperature units (C or F) which will be used for all tem- perature displays. The user selects C or F by selecting function code Cd28 and push- ing the ENTER key. The factory default value is Celsius units. This function code will display “-----” if CnF34 is set to F
- Cd29Error codeThis is the desired action to be taken if an alarm occurs that severely limits the capa- bility of the control system. Depending upon what alarm has occurred, the actual action taken may not be the same as the desired failure action. The user selects one of four possible actions as follows: A - Full Cooling (stepper motor SMV at maximum allowed opening) B - Partial Cooling (stepper motor SMV 11% open) C - Evaporator Fan Only D - Full System Shutdown - Factory Default
- Cd30Error codeThe in-range tolerance will determine the band of temperatures around the set point which will be designated as in-range. For normal temperature control, control temperature is considered in range if it is within setpoint In-Range Tolerance. There are four possible values: 1 = +/- 0.5C (+/-0.9F) 2 = +/- 1.0C (+/-1.8F) 3 = +/- 1.5C (+/-2.7F) 4 = +/- 2.0C (+/-3.6F) - Factory Default If the control temperature is in-range, the IN-RANGE light will be illuminated. In-Range tolerance shall be set to +/- 2.0C upon activation of dehumidification or bulb mode (Cd33, Cd35, Cd48). When CCPC is actively controlling, IN-RANGE TOLERANCE is not considered. “-----” will be displayed whenever Dehumidification or Bulb mode is enabled or when CCPC with six hour re-activation is actively controlling. “-----” will be displayed whenever Frozen Economy Mode is operating
- Cd32Error codeThe current limit is the maximum current draw allowed on any phase at any time. Lim- iting the unit's current reduces the load on the main power supply. This is accom- plished by reducing the SMV position until current draw is reduced to the set point. When desirable, the limit can be lowered; however, capacity is also reduced. The five values for 460VAC operation are 15, 17, 19, 21 (Factory Default), 23
- Cd34Error codeThe current state of the economy mode option, “-----”, On, or Off. CnF22 determines whether economy mode offered. Economy mode is a user selectable mode of opera- tion provided for power saving purposes
- Cd35Error codeThe current state of the bulb mode option, “-----”, nOr, or bULb. (Replaced by Cd48 if CnF50, Enhanced Bulb Mode, is active.) Bulb mode is an extension of dehumidification control (Cd33). If dehumidification (CnF04) is set to “Off”, Cd35 will display “Nor” and the user will be unable to change it. CnF28 determines whether the bulb mode selection is offered. After a dehumidification set point has been selected and entered for code Cd33, the user may then change Cd35 to bulb. After Bulb Mode has been selected and entered, the user may then utilize function codes Cd36 and Cd37 to make the desired changes
- Cd36Error codeThis is the desired evaporator fan speed for use during the bulb Dehumidification and Humidification mode option. (Replaced by Cd48 if CnF50, Enhanced Bulb Mode, is active.) This code is enabled only if in the dehumidification mode (Cd33) and bulb mode (Cd35) has been set to “bulb”. If these conditions are not met, “alt” will be displayed (indicating that the evaporator fans will alternate their speed) and the display cannot be changed. If a dehumidification set point has been selected along with bulb mode then alt may be selected for alternating speed, “Lo” for low speed evaporator fan only, or “Hi” for high speed evaporator fan only. If a setting other than “alt” has been selected and bulb mode is deactivated in any man- ner, then selection reverts back to “alt”
- Cd38Error codeCode Cd38 will display the current supply recorder sensor (SRS) reading for units con- figured 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 re- corder sensor reading
- Cd39Error codeCode Cd39 will display the current return recorder sensor (RRS) reading for units con- figured 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 record- er sensor reading
- Cd43Error codeCd43 is a user selectable mode of operation that allows opening and closing of a me- chanical 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 and O selectable limits (LM). 2 2 This selection is only active if the unit has a CO sensor. If CAL is selected, the controller will zero calibrate the CO sensor input. 2 If the unit is not configured with AutoFresh, the CD43 will display “----”
- Cd44Error codeCode Cd44 displays the eAutoFresh CO and O values (CO and O ) and CO and 2 2 2 2 2 O limits (CO LIMand O LIM), respectively. 2 2 2 This function code will be dashed out if not configured for eAutofresh. This function code will be dashed if CO sensor is not detected, and a sensor is not 2 expected (didn't have one previously). This function code will display ChECK if a CO sensor has not been auto-detected at 2 the most recent power-up and was detected at a previous power-up.
- Cd45Error codeWhen 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 pressing 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 dis- play mode
- Cd46Error codeSelects 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
- Cd47Error codeThe variable temperature “degrees C or degrees F” setting is used with economy mode. Function code is ---- when unit is not configured for economy mode
- Cd48Error codeInitially Cd48 will display current dehumidification-mode; bUlb - bulb cargo mode, dE- hUM - normal dehumidification, or OFF - off. This display is steady. Pressing ENTER key will take the interface down into a hierarchy of parameter selec- tion menus (mode, setpoint, evaporator speed, DTT setting). Pressing ENTER key in any parameter selection menu commits to selection of the currently displayed param- eter and causes the interface to descend into the next parameter selection menu. All parameter selection menus alternate between a blank display and the current selec- tion 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 Cd48 display mode if that is the next higher). Available parameters and parameter ranges are a function of configuration options and previously selected parameters as indicated above. Whenever any pretrip test is initiated, dehumidification-mode g

- Cd55Error codeCd55 will display the discharge superheat values in °C / °F as calculated by the dis- charge temperature minus the discharge saturation temperature as calculated from discharge pressure. “-----” will be displayed if selection is not valid
- Cd58Error codeCd58 will display “CLOSE” if the WPS or CFS switch contacts are closed or if these options are not installed. When the WPS/CFS Override Logic is “TRUE”, the right display 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 lim- ited. 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 configu- ration 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
- Cd60Error codeCd60 contains a selectable temperature range used to determine the engagement point of the Evaporator Fan Pulsing logic. Default setting is -18.1°C. The user may change the temperature by pressing enter, then scrolling to the desired temperature using either arrow key. The temperature setting will be retained until either a Pretrip or Trip Start is initiated at which time the temperature will set to the default setting
- dAL70Error codeThe supply recorder sensor reading is outside of the range of -50 to 70C (-58F to +158F) or, the probe check logic has determined there is a fault with this sensor.
- dAL71Error codeThe return recorder sensor reading is outside of the range of -50 to 70C (-58F to +158F) or, the probe check logic has determined there is a fault with this sensor.
