PROTECTION SYSTEMS
6.5.1
COMPRESSOR DELAY PROTECTION
The compressor delay time is adjustable (F21) and set to 5 minutes by default. The regulator
uses this time setting to prevent continuous ON/OFF cycles. When the compressor has been
running and then stops, the next time it is started up, the regulator will check that the period of
time has passed before starting it up again; if not, it will wait for 5 minutes until the compressor
starts again. If the machine has just been started up, there will be a 5-minute wait before the
compressor starts.
6.5.2
PHASE CONTROL
When the 3 phases of the machine are connected incorrectly or a fault is detected in any of the
phases, the machine will stop and the error code "A91" will be displayed.
6.5.3
OVER CURRENT PROTECTION (If 23=0, disable)
Consumption is checked three seconds after the compressor starts up; if the current > F23 for 5
seconds, the machine will stop and error "A93" will be displayed.
