OK, then SET, select the F05 function with “+”

and “-”, set a24, d24 or 115 (as jumper) and

press OK.

E06

Solenoid valve current lower than minimum

threshold or disconnected solenoid valve

Check correct connection of the solenoid valve

and respective data. The alarm is self-reset.

E07 Solenoid valve current higher than

maximum threshold

Check correct connection of the solenoid valve

and respective data. The alarm is self-reset.

E08

Output short circuit. Alarm

The signaling of the code E08 alternates

with the indication of the interested output

is shown as Uxx where xx is the number of

the output and the value of dP.

Switch the device off and back on after having

checked the solenoid valve s stem.

E09 dP maximum pressure exceeded (F10)

Detected for longer than 20 seconds. Check state of filtering elements.

E10 dP sensor hardware offset out of range.

The self-calibration of the dP sensor has

determined that a value is out of range.

Disconnect the air tubes and repeat the

function. Take the device to be serviced if the

alarm occurs again.

E11 Maintenance deadline reached Carr out maintenance.

E12 dP sensor full-scale value reached

Immediate reporting without an dela .

Check state of filtering elements.

IMPORTANT: Running in this condition ma

damage the device.

E13

Minimum dP alarm value ranging from F12

to F21 (warning: the alarm is generated

with a fixed dela of 60 seconds).

Check the status of the filtering elements.

E14

Indicates that a valve in short circuit has

been excluded from the c cle. The

signaling of the code E14 alternates with

the indication of the interested output is

shown as Uxx where xx is the number of

the output and the value of dP.

An output is considered a short circuit if

not responding for 3 following activations.

An activation without error resets the

counting.

Switch the device off and back on after having

checked the solenoid valve s stem.

Description Of Operation

The installed SW version and the s mbol ---, meaning that coherence between settings

stored in E2Prom and the set jumpers is being checked, will appear on the displa when

the economiser is powered up. A corresponding error code will appear in case of

discrepancies between settings (see Alarms Table). Onl editing functions will be allowed

on the unit. The operator ma switch off the unit and configure the jumpers correctl .

S mbol 0_0 will appear on the displa if the test is entirel successful. The following

pages will then appear:

•In automatic mode (F01=1):

odP value alternating with OFF if the enabling contact (14-15) is open

odP value alternating with -0- if the enabling contact (14-15) is closed and

the fan is off

odP value onl if the fan is enabled and active.

•In manual mode (F01=0):

oOFF if the enabling contact is open (14-15)

o-0- if the enabling contact (14-15) is closed and the fan is off

Manual Operating Mo e F01=0

The economiser will work as a programmable c cle sequencer in manual mode. The

connected outputs will be activated at the programmable frequencies. Manual mode can

be activated b accessing the configuration menu and setting F01 to 0. F02 and F03 will

set the activation time and the pause time, respectivel .

Automatic Operating Mo e F01=1

B selecting automatic mode (F01=1), the economiser will work autonomousl can carr

out the pneumatic washing c cle onl when needed. The device will start the washing c cle

if the obstruction is higher than Threshold_dP_Start (F08). Washing is suspended when

obstruction drops under Threshold_dP_Stop (F09) level until it reaches a value higher than

the Threshold_dP_Start threshold once again. When washing is active, the economiser

respects the times set in F02 (operating time) and F03 (pause time).

Automatic Mo e With Force Cycle F01 = 2

Identical to the automatic mode, except for the fact that it is possible to obtain a cleaning

c cle with the activation of the solenoid valves connected without reaching the

Threshold_dP_Start (F08). The forced cleaning interval ma range from 1 to 999 h and can

be selected through function F22 and F23.
