START-UP AND OPERATION

Stoppage procedure:

- Press the 

STOP button (O)

 to activate the stoppage

procedure. The load solenoid valve is deactivated and the

no load cycle starts for the time set in the parameter

“Stoppage time” (

“NO LOAD ”

 and then “

STATUS

 -

OFF”

 are displayed)

Remote pressure

- By enabling remote pressure control using the parameter

“Enable remote”

, the remote pressure digital input is is 

enabled. The control unit in this configuration keeps the 

remote input under control like an external pressure switch. 

Furthermore, it is also controlled that this acts within the range 

of the values set (load set, no load set or working and delta 

pressure in the event of an inverter). If the set pressure is 

surpassed due to an anomaly on the remote pressure control, 
the control unit will take command of the compressor cycle by working with the internal set values, signalling a 

“Remote press. 

err.”

.

If the anomaly is solved, pressure control is again entrusted to the remote pressure input, (at this point the alarm can be reset).

ON/OFF remote

Using the 

“ON/OFF from remote”

 the compressor can be activated remotely, by pressing the 

Start (I) key.

 Provided no alarms 

are on, remote start-up takes place. The remote command has less priority over the 

Start (I)

 and 

Stop (O)

 keys on the panel.

Compressor Functioning with an Inverter

Start-up procedure:

Press the 

START (I)

 button. If no alarms are on, the start-up cycle activates:

-Stand-by for start-up:

 the control unit is waiting to verify the following conditions before starting the compressor:

-If the machine was switched off or a previous stoppage was executed, the control unit waits 15 seconds before starting the 

compressor.

-The control unit waits for pressure to go under the value set in the “Working Pressure-Working Delta/2” set before starting the 

compressor. 

(“STAND-BY”

 is displayed)

-Compressor start-up:

 the line remote control switch is powered

-Fully operational compressor start-up: the line relay is maintained active and also the delta relay is activated; this phase lasts 

for the time set in the parameter “Load delay”. (“NO LOAD ” is displayed)

-Compressor loading phase:

 the solenoid valve relay of the load is active. This phase lasts until the pressure measured

reaches that set in the parameter “Working Press. + Working Delta/2”.

(“LOADED ”

 is displayed)

-Compressor no load phase:

 the solenoid valve relay of the load is deactivated; this phase lasts as long as set in the parameter 

“No load time”. After this, the cycle re-starts from the Start-up stand-by phase

(

“NO LOAD ”

 is displayed)

In this phase, the control unit executes a control algorithm to keep the pressure as close as possible to the working pressure 

by adapting the speed of the motor based on air consumption.

Dryer Functioning

For machines supplied with a dryer, the control unit can control the drying cycle.

Using the 

“Dryer ON”

 parameter, if its functioning is enabled, which can be continuous or linked to compressor motor functioning, 

by setting the parameter “Functioning mode” 

The dryer motor is activated if the temperature is over the total of the temperatures defined in the parameters

“Temperature OFF” and “Thermic drift” 

and deactivated if lower than the parameter 

“Temperature OFF”

.

If the temperature remains outside the aforementioned limits for a time over that set in the parameter “Alarms delay”,

an alarm sounds (see ALARMS and WARNINGS paragraph)

To avoid damaging the motor due to over-frequent start-ups you can moderate re-starts for the time defined in the parameter 

“Minimum time”. (see DRYER MENU paragraph)

Condensate Drainage Functioning

For machines requiring the condensate drainage function using the parameter 

“Condensate drainage ON”

, the function 

can be enabled and defined by setting the parameter 

“Functioning mode”

The drainage solenoid valve stays on for the time set in the “Interval” parameter and remains deactivated for the time defined 

in the parameter “Opening time” (

see the CONDENSATE DRAINAGE MENU paragraph).
