Input WCI 9 2G WCI 6 JAP ** *** load allowed / press free (G2 Mentor only***)
Milnor sets all batch data (previous two tables and next six signals) before it enables the "transfer complete / start press" signal.
Output* WCIR 14 DD2 WCIR 30 DD1 ** o1/13 new formula
Output* WCIR 13 DD4 WCIR 29 DD3 ** o1/12 new customer
Output* WCIR 15 DD6 WCIR 31 DD5 ** o1/14 single cake
Output* WCIR 11 DDX WCIR 27 DDW ** o1/10 low pressure
Output* WCIR 10 DDV WCIR 26 DDU ** o1/9 third pressure
Output* WCIR 12 DDZ WCIR 28 DDY ** o1/11 no pressure / don't main press goods *****
Output* WCIR 16 DD8 WCIR 32 DD7 ** o1/15 transfer complete / start press
* For outputs from Milnor, Milnor does not normally assign either pin of the potential-free contact as the common. Hence, both pins
have unique pin and wire numbers.
** Not available for viewing on the Mentor screens.
*** On the G3 CBW, this input must be defined using an assignable input as explained elsewhere in this document.
**** Applies to G3 CBW (Mark 9) only. The 76032 CBW uses Mark 8 controls which do not provide boards with LED's.
***** An explicit "empty load" allied output is not provided with the CBW. However, the "don't main press goods" output may be
used for this purpose. For example, in a CBW-to-Milnor extractor allied interface, this output may be connected to the extractor
"empty load" input. In the "Post Wash Codes" zone of the Formula Programming Page, simply ensure that for the "pass-empty"
formula, Pressure = 00.

Defining Special Purpose Allied Interface Signals
—Detailed information on
programmable outputs and inputs is provided in the Mentor reference manual. You should have a
solid understanding of the sections on assigning functions, programming formulas, programming
Generation3 inputs and outputs (G3 CBW only), and assigning interpret relays (76032 CBW
only), before attempting to define outputs or inputs for allied interface use. The following
information supplements those explanations with regard to allied interface signals.
Mentor controllers are normally provided with a certain number of programmable outputs (and
inputs on the G3 CBW) in addition to those preprogrammed by the factory to meet the machine's
anticipated requirements. Any extra outputs and inputs are available for any use including
providing allied interface signals. Defining an output or input in the field involves wiring and
programming it.
3.2.1.
Wiring Programmable Outputs
—Connection points for programmable outputs are available
in every module electric box of the 76032 CBW and in the module section (right side) of the
main control box, on the front of the G3 CBW. Connection points are on the connectors
designated
WCA
. (Refer to the schematics to identify pins and wires.) However, programmable
outputs, by themselves, do not provide the potential-free contacts normally needed for allied
interface outputs. Normally, it is necessary to use the 120VAC signal provided by the
programmable output to control an
interpret relay
that in turn, provides potential free contacts.
(Refer to the interpret relay schematic page in the schematic manual.)
3.2.1.1.
Working With Interpret Relays
—Interpret relays are optional equipment. Generally, when a
CBW is ordered, the purchaser only buys the number of interpret relays he knows are needed.
Usually, these are for chemical supply pumps. If the need for special purpose allied interface
outputs was anticipated, interpret relays should be available. Otherwise, it will be necessary to
purchase and install an interpret relay for each allied interface output to be defined. (Contact
