F1 STOP :GSV Stop
F6: PowerKit
Time in seconds can here be entered. PowerKit solenoid valve opens before compressor stops.
F5:
Motor cut time
Through the feedback from the star-delta starter of the compressor (that the starter is in delta) the
control panel registers that the compressor is running. If this signal disappears the control panel will
give an alarm. In order to avoid the alarm message when starting up, where the starter has not yet
switched from star to delta position, a time delay of the alarm message is entered here with the F5 key.
The time delay is running from the moment the start signal has been given to the motor and is called
"Motor cut time". Can be set from 5 to 30 seconds.
F4: Stop
time
After STOP or CUTOUT has been set the time, according to which the compressor is to run, is set
with the F4 key. The value can be set between 0 and 120 seconds and is called STOP TIME. At
compressors running with a great difference between condensing pressure and suction pressure a
small stop time is set.
Note:
When stopping the compressor abnormal periodical noise might be observed if the stop time is
too long, and at the same time there is a high differential pressure. This appears in case of "oil
lapping" and should be avoided by reducing the stop time.
F3
:
Compressor type
Here the compressor type can be changed if after a cold start the wrong type has been entered. To
make the change, enter password "1.8". If the compressor type is changed, certain pictures and
setpoints will also be changed.
F2: Power
kit
With the F2 (under MENU 2) it can be indicated if the solenoid valve used for POWER KIT is
normally open NO or normally closed NC.
Power kit can be used if the suction/non-return valve needs help for closing when the compressor is
stopped. In case of a compressor stop Power kit has the function to send high-pressure gas into the
suction valve for 15 seconds in such a way that the valve is forced to close.
