9.3.2 System fault alarms
In occurrence of a HP Measuring Loop Error, condenser stages are unloaded when compressors are stationary
and loaded when compressors are running. Capacity stages are likewise loaded when compressors have been
started manually. Actuation takes place after the basic time has elapsed. No allowance is made for variable
times.
In occurrence of an LP Measuring Loop Error, compressor capacity stages are loaded or unloaded until about
50% of all available compressor capacity stages are working. Actuation takes place after the basic time has
elapsed. No allowance is made for variable times. In occurrence of all other Measuring Loop Errors, computa-
tion continues with the most recent valid value for the duration of the error.
EPROM and RAM errors are fatal errors and result in the controller going on HOLD, as correct running of the
program can then no longer be expected. Output signals are reset.
