Special Load Interface Requirements for the Milnor

Centrifugal

Extractor

Regardless of what device loads a Milnor centrifugal extractor or what type of system the
extractor is in, communication between the extractor and the loading device requires one or more

allied interface

connections (see Note 1). This document explains how to establish these

connections when:

• the centrifugal extractor is loaded by a Milnor CBW

or Milnor COBUC (wet goods shuttle)

and both devices communicate with Miltrac

™

(either the older Miltrac controller or PC

Miltrac software running on a MultiTrac PC),

• the centrifugal extractor is loaded by a Milnor CBW controlled by a Mentor

or Mark 8

Miltron

™

controller, but one or both of the devices

do not

communicate with Miltrac.

Unlikely and/or nonspecific loading devices (e.g., COBUC in a non-Miltrac system, CBW with
non-serial controls, allied tunnel) are not covered in this document. For such conditions, consult
with Milnor Technical Support.

Allied interface signals are referred to in this document by their common names only. Connection
points (terminal and pin number) are not provided. See the allied interface signals tables for this
information. These tables can be found both in manual MTPALI01 (see Note 1) and in the
schematic manuals for the individual machines.

Note 1:

For a detailed explanation of allied interfaces, refer to manual MTPALR01 “Allied Interfaces for

Milnor Automated Laundering System Machines (Mark 5 Controls and Later).”

When the Devices Communicate Via Miltrac

If the CBW or COBUC and the centrifugal extractor communicate with Miltrac, all batch data
and most operational data are handled by the Miltrac controller. Only the

start cycle

allied input

to the extractor need be used in addition. This signal ensures proper distribution by causing the
extractor to begin the cycle, and hence, to go from loading speed to distribution speed, as soon as
the goods transfer, and before too much water has drained out. This timing cannot be reliably
achieved by Miltrac.

If the centrifugal extractor is loaded by a CBW, this extractor input must be triggered by a CBW
programmable output, as explained in Section 2.6 “The

Start Cycle

Signal”. If loaded by a

Milnor COBUC, use the COBUC

finished unloading to Milnor

output to close the extractor

input (see Note 2). The COBUC is used where two or more extraction devices receive batches
from the same tunnel. Wire this COBUC output to each centrifugal extractor that receives goods
from the COBUC. Only the extractor that is currently receiving from the COBUC will respond to
this signal.

Note 2:

Two COBUC outputs perform similar functions:

finished unloading to Milnor

(TBC-1 and

TBC-2) and

finished unloading

(WCO-03 and WCO-04). The first is specifically for the Milnor

centrifugal extractor and closes when the bucket, tilting up to dump the goods, reaches its upper limit. The
second is for use by any other allied device.

When Devices Do Not Communicate Via Miltrac

If the CBW or the centrifugal extractor or both

do not

communicate with Miltrac, all

communication between the CBW and the centrifugal extractor is via an allied interface. This
requires that

data passing

is enabled on the Mentor or Miltron controller (Section 2.1). Batch data

passed from the CBW to the extractor includes the

extract code

(Section 2.3), the

empty load

signal (Section 2.4), and may include other batch data, if available (Section 2.2). Operational
signals from the CBW to the extractor include the optional

end extract (early call)

signal and the
