Safety placards should be posted along the fence and at each gate, alerting personnel to the haz-
ards within. At minimum, the size of lettering and distance between placards should be such that
anyone contemplating entering the fenced area will likely see and read the placard first. Wording
should be provided in each native language spoken by laundry personnel.

This document is to be used in conjunction with Milnor
®
document W6SYSSG “Micro 6 Systems
Schematic: Customer-Provided Safety Fence Gate Interlock”. You will find this schematic docu-
ment in the circuit guide for your machine. Together, these documents describe how to connect a
customer-provided gate switch or series of switches to any Milnor
®
shuttle, press, or centrifugal
extractor. Another Milnor
®
document—BNSUUI01 “Proximity Safeguarding for Automatic
Shuttle Conveyors”—discusses the general hazards that safety fencing addresses.
1.3.1 Precautions
BNSUUI02.C02 0000230275 A.4 D.2 A.3 1/2/20 2:04 PM Released
WARNING: Electrocution and Electrical Burn Hazards — Contact with electric
power can kill or seriously injure you. Electric power is present inside the
cabinetry unless the main machine power disconnect is off.
� Do not service the machine unless qualified and authorized. You must
clearly understand the hazards and how to avoid them.
� Perform all work with machine power locked out/tagged out.
WARNING: Strike and Crush Hazards — A traveling machine such as a shuttle can
strike, crush, or entrap you if you ride on it or enter its path. Traveling ma-
chines or their components can move automatically in any direction. Plac-
ing a system machine on line by energizing the machine control may
immediately summon a shuttle or other traveling machine.
� Lock out and tag out power to the traveling machine at the main ma-
chine disconnect if you must work in the path of the traveling machine.
1.3.2 Wiring Guidelines
BNSUUI02.C03 0000230274 A.4 D.2 B.2 12/11/20 2:30 PM Released
As explained in BNSUUI01, a gate interlock switch must have one pole per machine to be inter-
locked. Each pole on the switch must be electrically isolated from any other poles on that switch.
The gate interlock circuit for a given machine is a series circuit that includes one pole per switch
(per gate). This circuit is wired into, and becomes part of the machine's three-wire circuit (see
definition below).
