NOTE: Depending on installation layout, it may be
possible that in one of the 5 pole plugs, the power wires
(red/black) must be left unconnected.
1. Attach the cable to the housing (951893), screw the
retaining plate (1) and close the housing.
2. Loosen the screwss (2) and remove the connections
plastic cover (3).
3. Plug in the 5 pole connector (4) in either of the 5 pole
female connectors (5) of the unit.
4. Mount again the plastic cover (3) and fix it with the
screws (2).
SETTING THE LOCAL PARAMETERS OF THE UNIT
Before the unit can operate, a few configuration steps
must be accomplished:
1. Connect the power to the unit. It will appear briefly on
the display the current firmware installed and then the
hose reel address is shown (by default "001" ).
2. Press and hold F1 and F2 buttons until it is shown "SET"
in the display.
3. The display shows the message "A" (address) followed by
a number that increases progressively from 001. This
number is the hose reel number linked to the unit. Once
that the desired number is shown, press briefly F2 button.
NOTE: If it is needed to restart the hose reel number to
"001" , press briefly F1 button.
4. Now the unit shows the message "EoL" (end of line),
followed by "0" or "1". This parameter allows to indicate
whether the unit is end of line in the CAN BUS (1) or it is
an intermediate unit (0). Change the adjustment pressing
the F1 button briefly and press F2 button to confirm.

NOTE: If the unit is configured as end of line, the end
of line blue led lights up in order to ease the
identification of bus endings.
5. In the next screen the display shows the message "Dir."
followed by an animated bars graphic. This parameter
allows to set the fluid flow direction through the unit.
Press F1 button to set flow direction so that the
animated bars movement matches the fluid flow in the
unit. Press F2 button to confirm.
6. Having reached this point, the unit stores in its memory
all the parameters introduced and it is restarted with
these new parameters.
NOTE: In the case that the unit is restarted before
reaching this last step (due to a power loss or whatever
reason), the parameters introduced will not be stored in
the unit.
