WF30T Case Former Safety
1-3
1.4 Lock-out Compliance
The WF30T is lock-out / tag-out compliant on both
the electrical and pneumatic main shut-offs. Both
the main electrical disconnect and the Filter-
Regulator assembly can be locked out on our
WEXXAR Case Formers. Ensure that you lock out
the machine and adhere strictly to the safety
precautions listed in Section 6.2.1:
‘Preliminary
Checks’
prior to performing any repairs or
maintenance.
1.5 Compressed Air
Compressed air is used to power the movement of many machine motions. You must be sure
that the machine's main air solenoid valve is shut off before attempting to clear jams or make
minor adjustments which require you to get close to the moving parts of the machine. This air
valve shuts off when the guard doors are opened, or when the main power is switched off.
To safely carry out service or repair work on the machine, a lockable shutoff valve is located on
all WEXXAR machines upstream of the filter regulator unit. Padlock this valve in the
OFF
position for absolute safety during service work. Always follow local lock-out/tag-out regulations.
Always exercise caution when switching the compressed air back
ON
. Stay well clear of all
moving parts, as they may move quickly when the pressure is reapplied. Make sure that no other
people are in a dangerous position when switching the compressed air on.
1.6 Electrical Power
All WEXXAR machines use electrical power. Switch off the main power disconnect switch on the
control panel, and lock it out before attempting service work outside of the electrical enclosure.
Before performing service work inside of the electrical enclosure, disconnect all electrical power
to the machine (customer supplied disconnect).
The main supply voltage is typically 230V 60Hz 3-phase, but may range from 110V to 600V
depending on your specific requirement. Where possible, control voltages are 24V DC from a
built-in power supply.
1.7 Conveyor Drivebelts
Where used, the outfeed conveyor drivebelt systems used on WEXXAR packaging machines
operate at moderate speeds. Be sure to keep fingers well clear of all moving parts, as the
gearmotors develop substantial torque, and do not stop easily. Do not wear loose clothing or
accessories (e.g., neckties) when operating WEXXAR packaging machines.
1.8 Guard Doors
WEXXAR takes your safety seriously,
offering the added benefit of safety
guarding on all of our WF Series units,
which prevent operators from reaching into
the machine during routine operation and
maintenance.
