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.

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.
