System Grounding
On all metal detection systems, it is important for safety and performance to implement
good grounding techniques. This should be made at the appropriate point at the PSU
PCB. Care must also be taken to ensure that the head or frame does not carry earth
fault or operating currents from other systems. Earth ground connections should be
made at one point in the system, and this point is the PSU PCB.
Use waterproof cable glands at all cable entries. Recommended cable entries are listed
in this manual on page 288.
Caution
All wiring must be done in accordance with field wiring diagrams, the National Electrical
Code, and all local electrical codes. Do not route coil cables through the same conduit
with power cables or any large source of electrical noise.
Removing the Control Panel
Before removing the control panel, make sure the AC power supply is off. The control
panel is held in place with eight mounting bolts. Remove these bolts to gain access to
the search-head power supply unit (PSU) and relay printed circuit boards (PCBs).
Remote search heads have a separate control panel to access the PSU and relay PCBs.
Note: The control panel also has internal PCBs for the operator display, keypad, and
signal processing. If any of these items need replacing, disconnect the PSU and search-
head cables that connect to them.
Caution: When removing or working with the control panel be careful when tightening
the screws. Do not tighten them too tight or breakage will occur.
Caution: When removing the PSU PCB, ensure that star (crinkle) washers are used on
the two PCB-mounting pillars adjacent to J1 (mains AC power in) and J2. Additionally,
ensure that pillars between relay PCB and PSU PCB are properly tightened and secured.
AC Power Wiring
The detector power consumption is only 35 watts. It is recommended a lighting circuit
be used rather than a machinery power circuit. If this is not possible, and the line noise
triggers the detector, contact Thermo Fisher Scientific—as described in the “Contacting
Thermo Fisher Scientific” section at the end of the manual—for recommendations of a
suitable isolation transformer or power-line filter.
