How the safety system works (continued)
➢
Do not tamper with any part of the Safety System. The
Haeger Hardware Insertion Machine will not operate properly
if any part of the Safety System is removed or d a m a g e d .
➢
The heavy-duty, retractable Safety Electrical Cord is very
durable, but caution should be taken when
working close to
the edges of deep cans. Operating with the Safety System
Electrical cord too close to sharp metal edges may cut or
shear the cord off.
➢
Test the Safety System every day before you use the machine.
See the Safety System Test in this section of this manual.
➢
Never test or demonstrate the Safety System by placing
any portion of your body between the Upper and Lower
Tools.
➢
When operating the machine in the Non-Conductive Mode,
be very careful. Do not press the Down
Footswitch a second
time with any portion of your body near the tooling.
➢
Always wear the proper eye protection when operating this
Machine.
When the Upper Tool Holder moves up .015 in/.4 mm to .02 in./.5 mm, the Safety Switch Actuation
Screw actuates the Safety Switch which is mounted in the end of the machine ’ s Cylinder Adapter,
opening its contacts. When the Safety Switch contacts are opened, the Upper Tool either returns to the
Up position if the machine is in Conductive mode, or it stops if it
is in Non-Conductive mode.
In operation, when the Safety Switch is actuated in Conductive Mode and a non-conductive material is
between the Upper and Lower Tools, the Upper Tool Holder ’ s downward motion is reversed
immediately and returns to its Up position. If the Safety Switch is actuated and a conductive material is
between the Upper and Lower Tools, the machine will continue the hardware insertion cycle. The
machine will
apply the set down force to the conductive material between the Upper and Lower Tools
and then return to its Up position.
When the Safety Switch is actuated in the Non- Conductive Mode and any material is between the
Upper and Lower Tools, the Upper Tool Holder stops. At this point, if the Down Footswitch is depressed
a second time, the machine will continue the hardware insertion cycle by applying the set down force
to the material between the Upper and Lower Tools and then return to its Up position.
