Function key F6 can be used to leaf to the I/O picture showing digital inputs "IN 4" to "IN 7".
IN 3 START COMPRESSSOR
If the compressor is set for the operating form REMOTE the start signal is applied to the compressor
via this input.
IN 2 PREVIOUS > MINUMUM
With master-slave operation, the slave sends a signal to the master compressor via this input - when
the slave is higher than its setpoint for minimum capacity.
IN 1 COMPRESSOR RUN
A signal from the star/delta starter of the compressor motor is applied at this input when the motor is
in delta position.
IN 0 OIL LEVEL
A signal at this input is a sign that the oil level in the oil separator is OK.

IN 7
EXTERNAL ERROR
If the safety pressure control KP7ABS stops the compressor due to a too high pressure in the oil
separator, or if the emergency stop is activated, an external fault will appear, as the connection to IN 7
then will be disconnected. In 7 can furthermore be used to stop the compressor due to an external
fault. See the electrical diagram how to connect emergency stop and safety pressure control or how
external fault reports can be made.
IN 6
CAPACITY DOWN
With the operating form SLAVE or REMOTE WITH EXTERNAL SETPOINT the signal arrives
from an external source when an increase or reduction in compressor capacity is required. If the
requirement is a reduction in capacity, the signal is applied at this input.
IN 5
CAPACITY UP
Whit the operating forms described under IN 6, a signal is applied at this input when compressor
capacity is to be increased.
IN 4 START SLAVE
If the compressor is set for the operation form SLAVE the start signal is applied to the compressor via
this input.
