Visual Error Codes - Digital Display
The following malfunctions will be displayed directly on the digital display by a code and will be
followed by a system halt. Whenever any of these codes appear the system is stopped for approx.
60 seconds and then a restart is attempted. If for more than 30 minutes the same malfunction occurs,
the system will be stopped completely and the error code will become steady. No more restarts will be
attempted and the user will have to re-set the system by pushing the
key or by temporarily cutting
out the AC supply to the system.
Code A01 to A08:
Pressure safety cut-out of compressors 1 to 4. The HP and LP (if present) safety
controls are directly controlled by the micro-processor including the time-delays for restart, etc. See
note *) Standard TCC controller cards have only 1 outlet for 1 single compressor. However the
embedded micro-processor program can operate up to 4 SC units from 1 single controller card. This
special controller card can be obtained on special request but is not standard delivery.
ATTENTION
*) Models SC5 to 12 do not have a low pressure safety switch (LP); therefore if you see a A01 warning on such
model, it can only be an electrical connection problem on the 3 pole HP/LP connector on the TCC controller
card. Check that the connector is properly seated and that the LP strap is properly tightened.
If any of these error codes appear too frequently and no appropriate action can be taken with the available
means on board, it is necessary to call a specialist.
Do not insist with manual restarts in such case as this may cause major damage to the principal components
(compressors, pumps, etc.)
