How to Do a Test of Emergency Stop Mechanisms

BNWUUH01.C05 0000335566 A.7 B.21 A.4 2/23/21 11:58 AM Released

This test applies to machines that have one or more stop mechanisms in addition to the Stop but-

ton (

). Do this test at the intervals given in the maintenance summary.

Definitions:

3-wire circuit

a series electrical circuit on a Milnor

machine that must close before the ma-

chine can operate. If a switch in the circuit opens, machine movement stops and the operator

alarm (a buzzer and a display message) comes on. When you push the start button (

), this

closes the 3-wire circuit, which stops the operator alarm and lets the machine operate.
