CO 1
Compressor minimum ON time
Determines the length of time the compressor must remain active after
being switched on, even if the request ceases.
CO 2
Minimum compressor OFF time
Determines the length of time the compressor must remain deactivated
even if a request is transmitted for it to switch on again. During this stage,
the LED pertaining to the compressor will flash.
CO 3
Minimum time between one activation and another on the same
compressor
CO 4
Activation delay between 2 compressors/steps
With two compressors this establishes the start-up delay between the
two, to reduce absorption at peaks. During this stage, the LED pertaining
to the compressor will flash. (only for the compressor)
With units with partialised compressor. This determines switch-on time of
the unloader solenoid for start-up at minimum capacity (see
compressors start-up)
CO 5
Shut off delay between 2 compressors / steps
This establishes the shut off delay between the two compressors two
unloader steps
CO 6
Not used
CO 7
Compressor switch-on delay from power ON (power from the mains).
Delays activation of all the outputs in order to distribute the mains
consumption and protect the compressors from repeated activation in
case of frequent power failures
CO 8
Unloaders operation (see unloaders operation)
0 = ON/OFF step insertion
1 = continuous insertion with direct action steps
2 = continuous insertion with inverse action steps
3 = Insertion with continuous direct global steps
CO 9
Enabling upon operation of the minimum power of the compressor / idle
start-up management
0 = Enables minimum power only upon compressor start-up (start-up
upon minimum capacity/idle valve start-up in OFF with compressor off)
1 = Screw valves enable the minimum power at compressor start-up and
in temperature control (start-up with minimum capacity / idle start-up
valve in OFF with compressor off)
2 = Screw valves enable the minimum power at compressor start-up
(start-up with minimum capacity / idle start-up valve in ON with
compressor off)
3 = Screw valves enable the minimum power at compressor start-up and
in temperature control (start-up with minimum capacity / idle start-up
valve in ON with compressor off)
CO 10
Screw compressor intermittent valve control relay ON time
0 = function is disabled
CO 11
Screw compressor intermittent valve control relay OFF time
CO 12
Compressor start-up (see compressor start-up)
0 = direct
1 = part - winding
2 = star delta
CO 13
Start-up is part-winding or star-delta
If CO12 = 1 part - winding start-up time applies. This allows you to vary the
attachment of the two relays that supply the two motor coils.
If CO12 = 2 star triangle start-up time applies. This allows you to vary the
simultaneous operation time of the line 1 relay and the relay that closes the
star centre connection. (see start-up par.)
CO 14
Star - Delta start-up
If CO12 = 2 star triangle start-up time applies. This allows you to vary the time
from unhooking the star centre relay from the hook on the relay of line 2 (see
start-up par.)
CO 15
Switch-on time with gas bypass valve / idle compressor start-up valve
(see unloader mode)
CO 16
Selection criteria of compressors in the circuit
0 = Fixed sequence
1 = FIFO
2 = Balance
3 = Saturation
CO 17
Selection criteria of circuits
0 = Fixed sequence
1 = FIFO
2 = Balance
3 = Saturation
