Carrier Supra Unit.

Could I please get some help on this Carrier truck unit that I'm working on. It came to me with the fans going slow and then they totally stopped and now I have no fans and an Alarm 15 error. Any Ideas or manuals. Many thanks

Hey Fredy have a look at these.
I don't do transport but these were passed on to me a while ago for Supra and Nordic units may be of use to you.
At least that's what i think they are for:D

l0= engoil = low oil pressure
al1= eng hot= high coolant tempreture
al2= hipress= high pressure
al3= startfail= start failure
al4= low batt= low battery
al5= hibatt= high battery voltage
al6= defrail= defrost overide
al7= alt aux= alternator auxillary
al8= starter= starter motor
al9= ra sensor = return air sensor
al10= sa sensor= supply air sensor
al11= wt sensor= coolant tempreture sensor
al12= highcdt= high discharge tempreture
al13= cd sensor= discharge temerature densor
al14= sbymotor= stnd by motor overload
al15= fusebad= fuse open
al16= system ck= system check
al17= display= display
al18= sevice1= maintenance hour meter 1
al19= service2= maintenance hour meter 2
al20= rasout= main compartment out of range
al21= 2ra out= remote compartment 2 out of range
al22= 3raout= remote compartment 3 out of range
al23= no power = no power for standby
Cheers

Thanks Stu, is there any other info you have on this unit. Unfortunatley I'm unable to get the model no. its not anywhere on the unit.

unclip lh panel there is a id plate inside giving model number if missing what gas is it on that gives a rough age

[fredyR717]

The unit runs on R404A, and is on a 8 ton truck with two blowers.

Sorry Fredy that's it , it was sent on to me and if I'm honest means absolutely nothing to me .
I'M sure one of the transport lads will be able to help you out when they get out of the pub;)
Cheers

check the brushes in the motors access thru the black knurled caps they are about an inch long when new then check the fuses.

Open the Engine door,(passenger side) serial plate there to the left of the electrical posts, but you say there are two fans...my guess its a Gensis R90 if so it has a gen under the electric motor that powers the fans. check the Alt belt is there and tight, check out put from the Gen (AC)..

If it does have a monophase 220v gennie under the standby motor you could also check the condensors (electrical) in the electrics box. If you open the door they should be attatched to the door itself (2 off). they show up on the wiring diagram as C4 & C5. Use the same capacity items as the voltage is dependant on this.

If it is an R90, there are capacitors in the evaps also, I have seen them go bad before. Make sure the engine speed is correct.
