3.1 Safety Features
The unit is manufactured with several built-in
features to promote safety and proper operating
procedures.
WARNING
Never bypass any of the
safety devices.
Serious Injury Could Result.
There are five general categories of safety
features:
Main Disconnect Switch
Safety Stop Buttons
Safety Sensors and Guards
Safety Interlock Switches
Safety Labels
Main Disconnect Switch
The main disconnect switch (Figure 3-2) is
located at the rear of the right endframe. When
turned to OFF, the main disconnect switch locks
out the incoming electrical power to the unit.
Unless otherwise indicated, turn the main
disconnect switch to OFF before performing any
maintenance or repair work.
For more information on operating the main
disconnect switch, refer to the INSTALLATION
chapter, Installation Procedures section,
Electrical Connection
subsection,
Standard
Electrical Wiring
procedure.
Safety STOP Buttons
Pressing any of the six red safety STOP buttons
(Figure 3-3, A) halts all moving parts, releases
internal air pressure, and locks out operation of
the machine. A fault message appears in the CHI
Panel display.
The preferred method to pause operation of the
machine is to press a red Stop button (Figure 3-3,
B) at the front of the unit near the center.

To completely power down the unit, press any
red stop button then twist to unlock it. However,
ChiLinc enabled machines require a different
technique. Instead, press the operator red Stop
button and hold it for 3 seconds. The machine will
completely power down and release internal air
pressure. To re-power the machine, press either
operator green Start button.
Safety Sensors and Guards
Two mass sensors at the bottom of the inlet
conveyor (Figure 3-3, C) help protect operators
and keep foreign objects out of the unit by
raising the upper inlet arm and shutting down the
unit. Crossbeam sensors (D) automatically shut
down the unit when triggered during machine
operation.
A windowed front access guard (Figure 3-3,
E) allows operators to see the internal parts of
the spreader/feeder when it is in operation while
providing protection from moving parts.
Each endframe is covered by a protective door.
These prevent fingers or hands from coming into
contact with moving parts. They also serve to
keep objects, other than flatwork, from entering
the unit and damaging components.
