Washer Signals
(North America Models)
The signal wires from each washer connect to their Multi-
Washer Communications Box using the row of connectors
at the lower edge of the circuit board, with the grounds
jumpered to have a common connection, as shown to the
right.
DIP Switch 5 - AFS Time
(NA Models)
On the DIP switch that identifies the Communications Box
(see above),
the fifth DIP switch is used to adjust the
time period
for Auto-Formula Select (AFS).
With switch 5 in the
Off position, 5 seconds
is the AFS
time, so an AFS signal of 15 seconds would select Formula
3. With switch 5 in the
On position, 3 seconds
is the AFS
time, so an AFS signal of 9 seconds would select Formula 3.
Level Probes Wiring:
An optional low level alarm (see section 5.0 Service Parts)
with up to 8 depletion wands can be connected to the
MW-3000 control cabinet.
The low level alarm is powered by an external power
source using a plug at 110-230 VAC. To wire the system,
connect the two wires from each depletion wand to the
appropriate contacts on the Level Board (see images at
right) and route the two-conductor cable from the Level
Board (A & B) through the opening in the bottom of the
cabinet and wire to the X2 terminal block at contact A2 and
B2 as shown.
(
* Note!
Although some of the X2 block connections are
labeled differently for the Metric and North America models,
the referenced
two bottom-row contacts of the X2
block are labeled A2 and B2
for both models.)
Internet Connection:
The controller cabinet has an
external Ethernet jack available for communication across
networks and over the Internet. In can be used as follows:
•
Cell Modem Connection
: If a strong enough signal is
available near the laundry room, you can connect the
controller to a cellular modem, to create a connection to
the Internet. A monthly data subscription is required.
