Interface Specifications and Signals, Single Stage
Press
An allied device that interfaces with the Milnor system machine equipped with Mark 5 or later
microprocessor controls must meet the electrical specifications and functional requirements given
in Section 1 “Electrical and Functional Specifications”.
The “Signals...” section(s) herein identify the allied interface signals and provide related
information (see Section 2 “How the Signals Tables Are Organized”).
This document also provides useful information for troubleshooting allied interfaces:
• The Display/code and Board/code values in the signals tables, are cross-references to the
output and input displays and to the output and input numbers on the I/O boards respectively.
Section 4 “Monitoring Allied Interface Outputs and Inputs”, explains how to use these cross-
references.
• As an aid in working with numeric signals , Section 5 “Decimal / Binary Conversion and
How It Applies to Allied Interfaces” explains how to determine, for any batch code, which
value (off or on) each signal in a group should pass.

Electrical and Functional Specifications
WARNING 1 : Electrocution and Electrical Burn Hazards
—Contact with high voltage
will electrocute or burn you. Power switches on the machine and the control box do not eliminate
these hazards. High voltage is present at the machine unless the main machine power disconnect
is off.
• Do not service machine unless qualified and authorized.
• Lock out and tag out power at the main machine disconnect before opening electric boxes
and accessing electrical components.
For inputs from Milnor (Milnor outputs), the allied device must limit circuit load to that specified
in Section 1.1, below. For outputs to Milnor (Milnor inputs), the allied device must supply
circuitry that meets the specifications in Section 1.2, below. The functional requirements stated in
Section 1.3 must be met for proper coordination and data exchange between the devices.
1.1.
Permissible Load for Milnor Outputs
—For signals from Milnor to allied (Milnor
outputs/allied inputs), Milnor supplies potential-free contacts located on board-mounted relays.
The signals are conducted by traces on the board having the following capacity:
• Maximum voltage: 240V
• Maximum current: 0.5 amps
• Maximum VA: 3
CAUTION 2 : Risk of Damage/Malfunction
—Traces on control boards may burn out,
requiring board replacement, if called upon to handle heavy currents. High voltages can cause
arcing across traces.
• Do not apply loads exceeding the specified capacity.
• Do not use allied interface outputs to operate motors or for any other unintended purpose.
These may, however, be used to operate relays that do not exceed the specified capacity.
