REJECT RESET (REJ RESET)
The metal detector has two reject outputs, Direct
and Timed. Either or both can be set to reset
manually following a reject. The Reject Reset input
can be used to reset the rejects. Normally a
momentary close push-button switch is used. The
electrical specifications are as follows:
Voltage
5 VDC
Current
20 mA
Note the right terminal of this input is ground. Since
the metal detector is to be grounded only by the
input power supply ground, this terminal must not
be grounded by the switch.
HOST COMPUTER PORT (MPC ONLY)
The MPC version is capable of communicating with
one or more host computers (typically PCs) through
an RS232 or RS485 link. Please refer to the E-Z
Tec MPC Communication Manual MM-237 for
further information on the use of this port.
PRINTER PORT (MPC ONLY)
The MPC can drive a remote printer through an
RS232 link to print reject reports. This subject is
covered in detail in Appendix A, Printer Operation.
CONDUIT
It is always wise to run wiring to and from the metal
detector through metal conduit. High voltage wiring
for the power supply and reject devices should not
be installed in the same conduit as low power sensor
wiring (such as wiring for the tachometer and reset
switch). Always keep all metal detector wiring
separate from cables carrying heavy or switched
loads. This is especially true with variable speed
motor control wiring. If these guidelines are followed,
interference from electrical noise will be greatly
decreased.
The use of metal conduit will provide necessary
shielding for the wires within; however, metal conduit
also represents a potential ground path. Metallic
conduit or airlines must be electrically insulated
from the associated components of the metal
detector, such as conveyor, stand or any other
support structure. Metallic conduit fittings must
not be used to attach conduit to the metal detector
housing. Always use a plastic fitting for this
purpose. Conduit for "other" equipment must not
be run along the metal detector conveyor.
Although the conduit serves as shielding, possible
interference could occure.
NOTE: The power on/off switch located inside the
power supply enclosure is intended to be a service
convenience only. It is recommended that the unit
remain on continuously. This will provide best metal
detector performance and enhance the longevity
of the electronic components.
CAUTION:
Be careful to distinguish between the input voltage
selection switch and the power (off/on) switch. Both
are located in the lower left corner of the power
supply circuit board. THE VOLTAGE SELECTION
SWITCH IS RED, AND IS LABELED WITH THE
AVAILABLE VOLTAGES, 115V AND 230V. THE
POWER SUPPLY SWITCH IS BLACK, AND IS
LABELED WITH 0 AND 1, TO INDICATE OFF AND
ON, RESPECTIVELY. INADVERTENT USE OF
THE IMPROPER SWITCH COULD LEAD TO
CIRCUIT DAMAGE AND/OR PERSONAL INJURY.
See Figure 14 for the location of these two switches.
INITIAL TEST (ANALOG UNIT)
a. After all electrical connections are com-
pleted and checked, turn the power switch,
SW4, on. The two center green LED’s in
the bar graph of the metal detector control
panel (Figure 15) should light.
b. Pass a large piece of metal through the
metal detector aperture. The LED bar graph
should respond with positive and negative
excursions of the red LED’s.
c. If the above does not occur, check all in-
stallation instructions, fuses, and input
power. If the fault cannot be located, con-
tact Eriez Magnetics for assistance.
d. Close and latch the power supply enclo-
sure door.
