SAFETY PRECAUTIONS AND WARNINGS
These operating instructions must be read, understood, and implemented by all personnel
responsible for this system.
All mechanical and electrical work must be performed by qualified personnel only.
Always disconnect power before servicing.
Refer to the machine serial number nameplate and drawings supplied with this system for
actual power requirements.
Be sure to install the equipment with the proper electrical connections according to all national
and local regulations.
Electric power supply should be through a separate disconnect switch with properly sized
overload/fuse protection.
The customer is required to operate the equipment with all safety features in proper working
condition.
NOVATEC shall provide no further guarantee for function and safety in the event of
unauthorized modifications.
2.1 Safe Access to Guarded Blade Area
It is safe to access the guarded blade area when the power is on.
NOVATEC Cutters use
a servo that has built in safety. It can execute a Safe Stop on E-Stop and has a Safe Torque
Off which is executed within 0.5 seconds of E-Stop. It also is monitoring itself for Safe
Standstill which is interlocked to the guard lock. With the addition of redundant safety relays,
motor contactor and guard interlock, the system can exceed SIL-3, PL-d safety requirements
for a Cat3 safety hazard.
NOTE:
Additional guarding may be required where the product enters and exits the
bushing.
NOTE: The Safety Circuit Must Be Tested on 90 Hour Intervals
To meet the requirements for a Cat3 safety system, the safety circuit must be tested at regular
intervals to insure that it is functioning properly. When the system is first powered on, the
power must be engaged and then the E-Stop activated to ensure that it is functioning. After
90 hours of continuous operation a Warning Message will appear instructing the operator to
perform the safety verification test which involves pressing the E-Stop and the resetting the
circuit. Production can continue while the message is present but arrangements should be
made to perform the test as soon as possible.
Even though there is no power to the blade when the system is E-Stopped, there is still the
hazard of the sharp blade. Care should always be taken when working in this area.
Please contact Novatec if there are any questions or concerns.
