2.O5 Electrical Connections (continued)
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:
The MW-3000 control cabinet can be used to power (24
VDC) a Hydro Low Level Alarm (Model # HYDLLA2000L8D)
connected to up to 8 product depletion wands.
To wire the Low Level Alarm (LLA), connect the two wires
from the probe 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.
