SET POINTS
Set point C
01-01-94 17:25:35
SETPOINT/SETP A-E/SETP. C/
F6 NEW (F6) :Startup capacity 0.0 %
F5 NEW (F5) :Minimum capacity 50.0 %
F4 NEW (F4) :Ampere normal 100.0 %
F3 NEW (F3) :P-disch. alarm 40.0 C
F2 NEW (F2) :P-disch. cutout 45.0 C
F1 STOP :
F6: STARTUP
CAPACITY
When starting up compressor will run capacity slide forcibly up to what is entered in % (Cpos %)
F5: MINIMUM
CAPACITY
When starting the compressor the capacity will always be adjusted upward to the minimum capacity
indicated here. If the compressor is running as slave it will always run up to minimum 25% no matter if
e.g. 20% has been entered here.
F4:
AMPERE CONSUMPTION NORMAL
This set point is set in %, and indicates the normal power consumption. If for example 100% is set here
it will correspond to the compressor motor having to run with full load current the whole time. When
the motor current reaches this value less 10% the signals for upwards adjusting of capacity will be
halved. When the motor current reaches this value less 3% the upwards adjusting is stopped, and if the
motor current exceeds this value anyhow, the slide valve for relief of the compressor will be adjusted
downwards. In the latter condition "AMPERE" is shown on the message line of the picture and a start
signal is sent to a slave if connected.
F3: P-DISCHARGE
ALARM
This outlet pressure (in degrees Celsius) triggers an alarm and at the same time the compressor capacity
begins to regulate down.
F2: P-DISCHARGE
CUTOUT
This discharge pressure (in °C) will stop the compressor.
Set point D

SETPOINT/SETP A-E/SETP. D/
F6 NEW (F6) :Cap. internal 15.0 Sec.
F5 NEW (F5) :Cap. up factor 25.0
F4 NEW (F4) :Cap dowm factor 50.0
F3 NEW (F3) :Liquid inj. off 40,0 C
F2 NEW (F2) :Liquid inj. on 45,0 C
F1 STOP :
F6: CAPACITY
INTERNAL
The interval time between regulating pulses for capacity can here be entered
F5:
CAPACITY UP FACTOR
The higher value (%) is set here, the faster upward adjustment, as this value is proportional with the
pulse duration for capacity up.
F4:
CAPACITY DOWN FACTOR
As F5, where it is a question of the signal for downward adjustment of capacity. The value here should
typically be higher than the above value. To both set points it applies that the greater difference between
discharge pressure and suction pressure the smaller has the regulating factor to be to avoid hunting of
the slide valve.
F3:
LIQUID INJECTION OFF
