1.2 ELECTRICAL INSTALLATION
The Ultra Advantage Sequential Servo Roll Feed has been designed to make electrical connections quickly and
easily. All that is required is a "clean" 220 VAC single-phase 15-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 process equipment (press, punching bench, etc,.) control (i.e. Emergency Stop, Feed
Cam Signal /Feed signal, Reset Cam Signal/Reset signal, Pilot Release Cam Signal,) must also be connected for proper
operation.
The motor connects by factory installed "Amphenol" (Military Specifications) Quick connectors.
For more detailed wiring information, refer to Electrical Schematic:
A-18164-06 – Ultra Advantage Sequential-US-standard.
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 Advantage Sequential
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 Advantage Sequential 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
