Check mains supply voltage is within
operating range of 207 – 253V.
Isolate mains supply from TM TCM, reset
6A ACU MCB and power up TM TCM.
Is the ACU functioning correctly now?
Is fault indication still present?
Contact an Engineer
Use TM TCM CCT DWG 226671 as reference for further
fault finding.
Use TM TCM CCT DWG 226671 as reference for

Check temperature of the processed air entering the
printer.
See Temperature sensitive label located on the TM TCM
Exhaust Air deflector. Green coloured block indicates
temperature. With heaters off a correctly functioning ACU
reading is 10 –15°C.
Is temperature higher or lower than SV (Set Value)?
