PROGRAMMING SWITCHES
These switches are located in the power supply
housing of the analog metal detector. They are
labeled SW1 and SW2. The functions controlled
by these switches are detailed in the section “Circuit
Board Switch Programming.” Note that these
switches are not present in the MPC metal detector
because the relevant functions are controlled by
user input at the front panel (or through the
computer interface).
FAULT INDICATOR
There are two conditions that can cause the FAULT
LED on the analog control panel to illuminate. These
two conditions are indicated on the output control
panel (in the power supply housing) as BALANCE
and REJECT and are explained below.
BALANCE LED
When the BALANCE LED is illuminated it
indicates that the coils in the search head are
out of balance and the sensitivity of the metal
detector may be in question. The coils must be
out of balance for approximately two minutes
before this is considered a fault condition and the
fault relay actuates. The BALANCE LED is reset
as soon as the coils are balanced.
REJECT LED
The REJECT LED indicates that there was not a
confirmation signal from the reject device when it
was to reject metal within the last two minutes. The
REJECT LED only indicates a fault condition when
SW1-1 is set to enable the reject confirmation.
RELAY STATUS LEDS
The five RELAY STATUS LED’s on the output
control panel in the power supply housing indicate
the state of the five relay outputs. The two solid
state relays are optional, but the status LED’s will
always indicate what their status is even if the solid
state relays are not installed.
DIRECT
The DIRECT LED is illuminated when the metal
detector is operating properly and no metal is
detected. As soon as the metal is detected the
DIRECT LED turns off to indicate that the direct
relay output has changed states. The DIRECT LED
illuminates as soon as there is no metal being
detected and direct relay output has returned to
its normal state.
TIMED
The TIMED LED is off when the timed relay output
is in a reject state.
ACSSR
The ACSSR LED is off when the AC solid state
relays output is off. The AC solid state relay
operates at the same time the TIMED RELAY
operates. The output of the AC solid state relay
may be on or off during reject depending on the
setting of SW2-4.
DCSSR
The DCSSR LED is off when the DC solid state
relays output is off. The DC solid state relay
operates at the same time the TIMED RELAY
operates. The output of the AC solid state relay
may be on or off during reject depending on the
setting of SW2-4.
FAULT
The FAULT LED indicates the status of the
FAULT RELAY output. The FAULT LED is
normally illuminated and turns off when a fault
condition occurs.
WINDOW LED
The Window LED on the analog output control
panel is illuminated to indicate the period of time
during which a reject can occur when switch SW2-
2 is set to enable INDEXED reject.
INDEX IN LED
When a proximity sensor is used to locate the
package to be rejected the INDEX IN LED
illuminates when a package is detected. If a
proximity sensor is not used this LED does not
illuminate.
CONFIRM LED
When reject confirmation is used to verify the
operation of the reject device, the CONFIRM LED
illuminates to indicate a signal from the reject
confirmation device was received. If reject
confirmation is not used the CONFIRM LED does
not illuminate.
