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.

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 system.
E11 Maintenance deadline reached
Carry out maintenance.
E14
Indicates that a valve in short circuit has
been excluded from the cycle.
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

Description Of Operation
The installed SW version and the symbol --- , meaning that coherence between settings stored in
E2Prom and the set jumpers is being checked, will appear on the display when the sequencer is
powered up. A corresponding error code will appear in case of discrepancies between settings (see
Alarms Table). Only editing functions will be allowed on the unit. The operator may switch off the unit
and configure the jumpers correctly.
Symbol 0_0 will appear on the display if the test is entirely successful. The following pages will then
appear:
•OFF if the enabling contact is open (14-15)
•-0- if the enabling contact (14-15) is closed and the fan is off
Operative Mode
The device works as a programmable cycle sequencer. The connected outputs will be activated at the
programmable frequencies. The firing and pausing times can be set on the configuration menu.
Cleaning F nction With Fan Off (PCC)
This function allows to carry out one or more cleaning cycles (the number of cycles is defined by F13)
when the fan is off. The on or off state of the fan is determined by the state of contacts 12-13 (contacts
open = fan off). The pulse time of the valves will always be that defined in F02, while the pause time
in this case is defined in F14.
The display alternately shows the number of the valve activated and the word PCC.
N mber Of O tp t Selection
The number of outputs (solenoid valves) on which the sequencer will run the cleaning cycle can be
selected. Cleaning will be carried out in order from the first to the last solenoid valve. The valves can
be adjusted by the F04 function.
F se
A fuse which can be reset in case of need is located near the power terminal board. Use a delayed
fuse 5x20mm as shown in the table on page 10.
