4.7 Power protection
The power protection feature is two-fold; it consists of both power fluctuation protection and power
surge protection. Special safety components built into the electronics of the machine make it more
reliable in situations where power supply can be of varying quality due to factors:
- Around the workplace, for example caused by switching on high power or unreliable
electrical devices, a broken circuit breaker or faulty wiring;
- Outside the workplace, for example caused by an instable power grid or lightning.
A machine with this feature is able to cope with standard rated voltage and frequency fluctuations
ranging from:
- 110 Volt to 130 Volt and 45 Hz to 65 Hz, or
- 220 Volt to 240 Volt and 45 Hz to 65 Hz
reducing the probability of breakdown and minimising down-time and repair cost.
Power fluctuation protection
When the frequency is too high (above 65 Hz) or too low (below 45 Hz), the motor will not start. If
the frequency of the power supply falls outside the range during your drilling job, the motor will shut
off automatically. The machine will work again normally when the normal frequency has been
restored.*
Power surge protection
Beyond the rated voltage, a machine with this feature is able to cope with voltage spikes up to 4,000
Volt (1-2μs)*. Depending on the height of the spike, it may be necessary to replace built-in fuses, the
control unit or the power switch, but other valuable parts like the motor and magnet will be
protected.
*Disclaimer: EUROBOOR is not liable for any damage caused to the machine due to electrical
problems in the workplace. Above mentioned protection is not guaranteed in all cases of voltage
spikes and/or frequency fluctuations. EUROBOOR accepts no liability when it comes to the power
protection not functioning or functioning poorly.
In the situation of the motor being shut off automatically as self-protection, you should:
- Shut off the magnet;
- Disconnect the machine from the power source;
- Fix the source of the problem, by either:
o
Making sure the issues with the power source is fixed;
o
Connect the machine to a different and reliable power source;
- Continue using the machine as described in this user manual.
4.8 Carbon brushes
This machine is equipped with carbon brushes with two protection features. The purpose of both
features is to schedule timely service and avoid additional costs by unexpected downtime or
unnecessary part replacement.
