BOOSTER
Start the Booster compressor. When the compressor is in mode “Ready to Run”, Yes/No can be chosen.
F5:
CAP. MIN. REG.FREE
In case of master/slave operation this set point is important. When a slave is moving downward at a
time it will reach its minimum entered for capacity (entered under set point C/F5). When minimum has
been reached the master will receive a message and further downward adjusting is now taking place at
the master, see description of master/slave operation under types of duty. If the slave should go under its
minimum it will receive a capacity up signal. To avoid hunting at this set point "MIN REG.FREE" it is
possible to indicate by how many per cent over the minimum of the slave you will give a signal to the
master that the slave has reached its minimum.
F4:
P-SUCTION SETP 2
As mentioned under set point A it is possible to run according to an alternative set point for suction
pressure; "SUCTION PRESSURE 2" (in °C) which is entered here. It is adjusted according to set point
for suction pressure 2, when resistance input R IN 4 is ON.
F3: BOOSTER
START
When the suction pressure has reached this pressure signal is given for start of booster (= low-pressure
compressor). This signal is sent to digital output 18 (OUT18).
F2: BOOSTER
STOP
The booster compressor is stopped when the suction pressure of the high-pressure compressor reaches
this pressure that is OUT 18 goes "OFF". In case of stop of the high-pressure compressor the booster
compressor will be stopped too.
