3.5.1.d. Dosing equipment connection. RELAY CONTACTS POWERED FROM THE WASHER CONTROL
CIRCUIT. (Fig. 3.14)
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 by
a fault in the grounding connection, both of the washer
itself and of the external dosing equipment.
The external dosing control board incorporates a connection point
(terminals identified as X0) allowing to generate dosing signals
from the washer control circuit.
Dosing signals connection (Fig. 3.14)
Follow the instructions on sections 3.5.1.a & b.
•
Supply X6-COM from terminal X0-A (wire not delivered).
•
Supply the common phase of the signal outputs from XO-B.
•
Dosing outputs: Connect in the order indicated in the following
•
chart.

IMPORTANT
Voltage between each dosing output signal X6 and X0-B, will be the same as electrical control circuit
(200...240V; 50/60Hz according to the washer).
INTELI CONTROL machines with optional auxiliary input and
output board I/O2 (identified on the electrical diagram as A6).
This option increases the number of external dosing signals by
eight (in total, the washer will feature twelve external dosing
signals).
The dosing signals of the auxiliary board are obtained via relay
contacts KA9...KA15.
The connection of these eight signals is made using the connector
X3. Common terminal: X3-1 (Fig. 3.15).
See the washer's electrical diagram for more information.
The connection options are the same as those described in
sections 3.5.1.c and 3.5.1.d.
