Other Wiring During Installation
For more information, see page 284.
Electro-Magnetic Environment
Loss of sensitivity and false rejecting can occur under the following conditions.
Your metal detector is located close to equipment using variable speed controllers or
high frequency heating equipment.
Your metal detector is located close to another metal detector operating at similar
frequencies.
Walkie-talkie, hand-held or radio frequency devices are operated close to the metal
detector.
Loss of sensitivity may go unnoticed due to radio-frequency (RF) signal "swamping" the
input circuits. If there is any doubt, check calibration of the search head under these
circumstances. For assistance in finding solutions to your EM problems, contact Thermo
Fisher Scientific—as described in the "Contacting Thermo Fisher Scientific" section at the
end of the manual.
Low Voltage Directives
All of the recommendations for EMC apply to the prevention of electrical shock.
If access to the PSU area is required, the incoming AC power supply should be isolated
remotely and locked-off. Access to the PSU area by untrained personnel is not
recommended.
Circuit Breaker
The APEX should be permanently connected to its AC supply. Please ensure that when
installing the APEX, a switch or circuit breaker is used and is positioned close to the
metal detector in easy reach of the operator. The switch or circuit breaker shall be
marked as the disconnecting device for the metal detector.
DO NOT install the APEX in a position that makes it hard to use the AC mains isolator.
