Installation Rules Notes and Warnings
Protect the device from direct exposure to sunlight.
Do not position the device near or directly in contact with sources of heat or
electromagnetic fields.
Fix the device of a height of at least 60 cm from the ground.
In a clearly visible place easily accessible.
Connect the device to power lines other than those for operating motors or other
large power devices which could generate network interference or instability.
The electrical supply of the unit must be protected by a differential switch 230Vac~
30mA and a bipolar magneto thermic 230Vac~ 10A, positioned in a place easily
accessible.
Before working on the equipment to perform any operation switch off the
magneto thermic differential switch.
For electric operations, always remove voltage, wait 30 seconds for the
inside capacitors to discharge before opening. At the end of the operations,
close the device to restore the correct degree of protection before powering up.
For the connection of the supply voltage, use anti-flame wires with a minimum
section of 0.75mm² certified and conform to the standard IEC60227 or IEC60245.

may cause damage to the device or to the devices connected to it.
Furthermore, incorrect use or tampering with the device may cause injury.
Waterproofness of the casing is guaranteed when the flap is closed.
Make sure that rigid or flexible ducts used for wiring, if any, do not fill up with water
or other liquids.
Do not make holes not protected on the container or protected by accessories with
protection degree lower than that of the housing of the control unit.
Cut off power supply immediately if water is found in the casing.
If the control unit is used in ways not specified by the manufacturer, the protection
provided by the device may be impaired.
The Control Unit does not release potentially toxic or harmful substances to the
health and the environment.
No part with dangerous voltage is normally accessible.
Do not use the control unit if you have not read or do not understand this manual.

Display / Keypad
There are four round buttons on the front panel for controlling the device on the front
panel. The display will appear similar to the following when it is turned on.
The SET button enables to enter and exit the
programming menu, and activate the manual test of
solenoid valve selected in function F06.
The + and – buttons enable to scroll functions from
F01 to Fxx. After entering one of the Fxx functions use
the OK button to select and then + and - increase or
decrease the values.
The OK button is used to confirm data and reset alarms.
If the + button is pressed during ordinary operation,
the activity hour meter is displayed.
The – Button pressed during the ordinary operation,
displays the counts partial hours of activity.

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 Function 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.
Number Of Output 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.
Fuse
A fuse which can be reset in case of need is located near the power terminal board. Use a
delayed fuse 5x20mm.
