1.2 ELECTRICAL INSTALLATION
The Ultra Edge Servo Roll Feed has been designed to make electrical connections quickly and easily. All that is
required is a "clean" 110 VAC single-phase 15-ampere source that must be connected to the corresponding terminal
blocks. 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 "ITT Industries, Cannon ®" (Twist Lock) Quick
connectors.
The optional PLS connects to the electrical control 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-18219-01 - UltraEdge-US-standard;
A-18219-02 - UltraEdge-CE-standard;
A-18219-14 - UltraEdge-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 Edge 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 Edge 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
