, 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.

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 as shown in the table on page 10.
