RELAY CONTACTS POWERED FROM THE WASHER

CONTROL CIRCUIT

Use of four dosing signals

The dosing signals from 1 to 4 originate from the board.

∙ Supply terminal COM from terminal X0-Aof A4 board. (cable not supplied) fig. 23.

∙ Supply common phase of the signal outputs from terminal X0-Bof A4board.

∙ Dosing outputs: connect in the order mentioned in the table

in section 3.6.2.
IMPORTANT
This connection allows for the maximum strength at
each of the 50mA outputs. Higher consumption can
prevent the washer from functioning correctly.
This connection can aggravate any problems produced	fig. 23
by a fault in the grounding connection, both of the	fig. 23
washer itself and of the external dosing equipment.

USE OF MORE THAN FOUR DOSING SIGNALS Applicable in both options, for dry contacts or relay contacts supplied from the machine itself.

The dosing signals from 5 to 12 are originated in A6 board (fig. 24)

∙Supply terminal COM of A6 board from terminal X0-Aof A4 board (cable not supplied).

∙Dosing outputs: connect in the order mentioned in the table in section 3.6.2.
