1.2 ELECTRICAL INSTALLATION
The Ultra Magnum Servo Roll Feed has been designed to make electrical connections quickly and easily. All that is
required is a "clean" 220 VAC single-phase 20-ampere source that must be connected to the main disconnect switch. It is
recommended that #12 MTW (Machine Tool Wire) be used for the primary power supply input.
The inputs and outputs to your press control (i.e. Emergency Stop, Feed Cam Signal, Pilot Release Cam Signal, Reset Cam
Signal) must also be connected for proper operation.
Note, that if your feed is supplied with P/A PLS (Programmable Limit Switch) you don’t have to wire Feed and Reset Cam
signals.
The motor connects to the electrical control by factory installed "Amphenol" (Military Specifications) Quick connectors.
The optional PLS connects to the electrical controls by factory installed Military Quick connector.
The optional Strip Encoder connects to the electrical control by factory installed Military Quick connectors.
For more detailed wiring information, refer to Electrical Schematic:
A-18335-01 – UltraMagnum-US-standard;
A-18335-02 – UltraMagnum-CE-standard;
A-18335-03 – UltraMagnum-US-with step-down transformer;
A-18335-03 – UltraMagnum-CE-with step-down transformer ;
A-18335-14 – UltraMagnum-US-with Strip Encoder .
IMPORTANT!
A #12 MTW GROUNDING CONDUCTOR MUST BE INSTALLED FOR PROPER MACHINE GROUNDING.
NOTE:
All connections should be made in accordance with National Electrical Code (NEC) requirements and must comply
with all local ordinances.
NOTE:
A word about electrical “noise” - Most pressroom environments contain considerable electrical noise. It is emitted
from electro-mechanical press relays, contacts, and solenoids. While the Ultra Magnum Servo Roll Feed has been
designed to minimize “self generated” electrical noise, it is difficult to provide protection for all applications. If erratic
system behavior is experienced, then the source of the "noise" must be suppressed with either a resistive/capacitive
type of suppressor on AC coils, or “Avalanche” type diodes on DC coils.
NOTE:
The Ultra Magnum Servo Roll Feed is fully protected by line circuit breakers.
NOTE:
The electrical control enclosure is supplied with a stand/support, which may be placed in any convenient location. The
enclosure may also be mounted in any fixed location as long as the cabling is adequate to reach the feed. It is not
recommended that the electrical enclosure be mounted directly to the press. The vibrations caused by the punch press
can result in damage to the control system
