CLOCK LED
The CLOCK LED is used to show the rate at which
the timer for the timed relay is operating. When the
internal clock is selected with SW2-3 the CLOCK
LED flashes at the rate at which the internal clock
is running. When SW2-2 is set to select the
tachometer input for the clock, the CLOCK LED
flashes at the rate at which the pulses from the
tachometer are occurring.
DETECT LED
The DETECT LED illuminates when the sensing
head sends a signal indicating metal has been
detected.
ANALOG CIRCUIT BOARD
SWITCH PROGRAMMING
Figure 17 shows the various switch locations on
the analog unit output control panel, PSOPT-1.
The user programmable switches are listed on
Page 23 along with a brief explanation of their
function. The discussion below provides a source
for quick reference.
SW1-1
When a reject confirmation device is connected to
the metal detector, SW1-1 must be set to the UP
position for the metal detector to process the signal.
If a reject confirmation device is not connected to
the metal detector, SW1-1 must be set to the DN
position or a fault condition will occur.
SW1-2
When this switch is set to the UP position the output
of the TIMED RELAY will not reset after a reject
until a signal is received at the REJ RESET input.
When SW1-2 is set to the DN position the TIMED
RELAY output will reset automatically. The time for
the relay to reset is determined by the STANDARD
REJECT TIME when SW2-2 is in the UP position
or by the INDEXED REJECT TIME when SW2-2 in
the DN position.
SW1-3 THROUGH SW1-8
These switches set the length of the shift register.
Refer to the SWITCH CHART for switch settings
and shift register length. Refer to Appendix B for a
discussion of the Shift Register function.
SW1-9
When this switch is set to the UP position the
DIRECT RELAY will not reset after a reject until a
signal is received at the REJ RESET input. When
SW1-9 is set to the DN position the DIRECT RELAY
output will automatically reset after a reject.
SW2-1
This switch selects MODE 1 or MODE 2 detection.
Refer to the DETECT MODE DESCRIPTION
section of this manual for an explanation of MODE
1 and MODE 2. MODE 1 is also referred to as
normal detection and is selected when SW2-1 is in
the UP position. MODE 2 is also referred to as
narrow zone detection and is selected when switch
SW2-1 is in the DN position.
SW2-2
This switch selects between INDEXED REJECT
and STANDARD REJECT for the TIMED RELAY
output. When SW2-2 is in the UP position,
INDEXED REJECT is selected and the reject time
is adjusted with the INDEXED REJECT TIME.
When SW2-2 is in the DN position, STANDARD
REJECT is selected and the reject time is adjusted
with the STANDARD REJECT TIME.
SW2-3
This switch is used to select an internal clock or a
tachometer input for the travel time on the TIMED
RELAY output. When the switch is in the UP position,
the source of the clock is from the tachometer input.
When the switch is in the DN position the source of
the clock is from an internal clock.
SW2-4
This switch is used to determine whether the
output of the solid state relays is to be ON
during reject or OFF during reject. When the
switch is in the UP position the output of the
solid state relays turns OFF when a reject
occurs. When the switch is in the DN position
the output of the solid state relays turns ON
when a reject occurs.
