If the compressor is operating at a capacity below 50% when the limiting function is active, the limiting function will not actively begin to load stages.However, the following will take place:– In MANUAL the compressor will be stopped on the "total unloading timer" provided that the capacity stays below 50% for more than approx 4 mins.– In AUTO and REMOTE the compressor will be stopped on the "total unloading timer" provided the regulator is neutral and capacity remains below 50% for more than approx 4 mins.– If the regulator sends out a regulating down signal, the timer STOP DELAY willbe started.– If one of the other limiting functions is to unload capacity, the timer DELAY DOWN will stop at 50/66%.– If the regulator sends out a regulating up signal and the compressor is loading stages so that capacity rises to 50% or more, the situation will be the same as the one described in the previous section.In the WARNING picture the text LIMITING DISCHARGE TEMP. will appear if the compressor isto be stopped on the "total unloading timer" due to insufficient capacity or if the limiting function prevents the capacity from being reduced in MANUAL, AUTO or REMOTE.The limit curve (limiting zones 2/4) corresponds as standard to suction superheating of 10°C (factory value).Since the limit curve is directly dependent on the suction superheating of the plant, the actual superheating of the plant must be entered as set point 2 in picture: SUCTION SIDE I SUCTION SUPERHEAT. I SETPOINT 2 if it differs from the above factory value.Adjusting range: -10 - +30°CBy adjusting SET POINT 2 parameter for suction superheating upwards or downwards, the limit curve will be dislocated accordingly.If SET POINT 2 is set for -10°C, the limit curve will be dislocated so much upward - 20°C compared to normal - that the limiting fuction will be disconnected.Display indicationsThe following tables show the texts appearing in the display in connection with the various limiters
