introduction Multi-Stroke Control Introduction The Multi-Stroke Control, when coupled with a Rapid-Air feed, increases the feed length by up to 9 times the original feed length capability. path to allow an external device to operate. The solid state relay will remain until the reset switch is tripped. The contact is rated at 0.5 AMPS/120 VAC. The control is completely self-contained and requires only 3 interface points, which are provided on the outside of the electrical enclosure.
b0ard components and troubleshooting There are two switches on the board for changing the operation of the cut-to-length. 1. The first switch is a bat or toggle switch. It is located just above the transformer on the board. When the switch position is to the left of the board, then the air feed will run at a normal speed.
maintenance The air feed needs very little maintenance. The most important part to watch is the air. Too much oil or water in the air can cause the air feed to start running erratic. Screws should be checked periodically to be sure they are tight. This includes the switch mounting brackets, if present, as they can loosen up over time due to the vibration and high impact movement of the air feed. A visual check of the air feed every morning before running it will help assure many hours of running time.
