2.5 Safety Guards
Under no circumstance must a machine be operated with any guarding removed
or interlock switches defeated.
Guarding
For Loma Metal Detection Systems the use of guarding, including covers, panels, curtains and
other methods is extremely important in order to restrict operators from accessing areas of the
machine that are potentially hazardous whilst the machine is operating.
Interlock switches
On some machines, access hatches are incorporated into the guards to provide access to
some areas of the machine to, for example, clear obstructions and remove products when
required. These hatches are fitted with an interlock switch so that when a hatch is opened, the
machine will switch off and a fault condition generated.
Safety Relay and Circuits
As safety is paramount, at least one fail safe relay is fitted to ensure that if a contact of the
interlocks were to fail the safety relay will automatically detect the fault and therefore switch off
the system and generate a fault condition.
