Carrier Transicold Alarm Codes Defined
This alarm triggers failure action C evaporator fan only or D all machinery off of Function Code Cd29 if the unit has a perishable set point. Failure action D all machinery off is triggered if the unit has a frozen set point AL14 Phase Sequence Failure -- Electronic Alarm 14 carrier transicold alarm codes triggered if the electronic phase detection system is unable to determine the correct phase relationship.
If the system is unable to determine the proper relationship alarm 14 will remain active. Additiotnal information on phase detection may be displayed at Function Code Cd If the right most digit of Code Cd41 is 3 or 4, this indicates incorrect motor or sensor wiring.
If the right most digit is 5, this carrier transicold alarm codes a failed current sensor assembly. The alarm is display only and will trigger off when the compressor operates for one hour without over current.
AL17 Phase Carrier transicold alarm codes Failure -- Pressure Alarm 17 is triggered if a compressor start in both directions fails to generate sufficient pressure differential.
The controller will attempt restart every twenty minutes and deactivate the alarm if successful. The alarm is display only and will trigger off when the compressor operates for one hour without overpressure.
Carrier Transicold Container Problem
The alarm is display only and will trigger off when the compressor operates for one hour without over temperature AL20 Control Circuit Fuse Open 24 vac Alarm 20 is triggered by control power fuse F3 opening and will cause the software shutdown carrier transicold alarm codes all control units.
This alarm will remain active until the fuse is replaced.

- Re: Carrier Transicold Container Problem
The suction modulation valve SMV will be opened and current limiting is halted. Temperature control will be maintained by cycling the compressor.

The alarm is triggered by opening of either internal protector. It will disable all control units until the motor protector resets and the unit is power cycled. If the compressor should be running, the carrier transicold alarm codes will initiate a start up every five minutes and trigger off if current reappears.
Carrier transicold alarm codes the evaporator fan motors only should be running, the alarm will trigger off is current reappears. Failure action D all machinery off is triggered if the unit has a frozen set point AL24 Compressor Motor Safety Alarm 24 is triggered when compressor is not drawing any current.
This alarm will remain active until compressor draws current. Table Controller Alarm Indications Sheet 2 of 4 AL25 Condenser Fan Motor Safety Alarm 25 is triggered by the opening of the condenser motor internal protector and will disable all control units carrier transicold alarm codes for the evaporator fans.
This alarm will remain active until the motor protector resets. Failure action D all machinery off is triggered if carrier transicold alarm codes unit has a frozen set point AL26 All Supply and Returntemperature Control Sensors Failure Alarm 26 is triggered if the Controller determines that all of the control sensors are out-of-range.

This alarm triggers the failure action code set by Function Code Cd The Controller continuously performs calibration tests on the A-D converter. If the Carrier transicold alarm codes converter fails to calibrate for 30 consecutive seconds, this alarm is activated.
This alarm will be inactivated as soon as the A-D converter calibrates. Alarm 28 is triggered if suction pressure is below 2 psia and alarm 66 Suction Pressure Transducer Failure is not active.
This alarm will be inactivated when suction pressure rises above 2 psia for three continuous minutes. This alarm triggers failure action C evaporator fan only or D all machinery off as determined by User Selectable Failure Response if the unit has a perishable set point; Failure action D all machinery off if the unit has carrier transicold alarm codes frozen set point.
Carrier Transicold Alarm Codes
This is done by testing the set point and carrier transicold alarm codes alarm list. If the contents are invalid, Alarm 51 is activated. During control processing, any operation involving alarm list activity that results in an error will cause Alarm 51 to be activated.
