To determine if your product should use high or low field strength,
observe the calibration indicators as the product passes through the metal
detector. If the lights brighten as the product passes, then the field
strength should probably be set on low.
Use the keypad and Menus 49 and 51 to change field strength.
3 - DETECT - Indicates that the metal detector has detected metal.
The indicator will come on immediately upon detection of metal and will
remain on until the detector resets. The length of time the indicator
remains lit is directly proportional to the size of the metal that was
detected.
The DETECT indicator also shows the status of Output 4. The Output is
active whenever the detect indicator is on.
4 - Output 1 - Indicates whether Output 1 is normally closed (on) or
normally open (off).
Upon detection of metal, the indicator will change temporarily to show the
condition of the
Output 1 relay.
Use the keypad and Menus 68 and 69 to choose "open" or "closed."
5 - Outputs 2 & 3 - Indicates whether Outputs 2 and 3 are normally closed
(on) or normally open (off).
Upon detection of metal, the indicator will change temporarily to show the
condition of the Output 2 & 3 relays.
Use the keypad and Menus 68 and 70 to choose "open" or "closed."
6 - CALIBRATION - Indicates the condition of the metal detector coil
assembly.
Metal detectors operate at peak sensitivity when the sensing coils are
tuned, or balanced.
In normal operation, indicator "A" should be on, "B" should be on but
dim, and "C" "D" "E" should be out.
If the detector loses calibration, indicators "C" "D" "E" will light,
in that order, and the balance adjustment should be attempted. See
"Balance Adjust" on page 15. When indicator "C" becomes as bright as
indicator "A," there has been a significant loss of detection sensitivity
and the balance adjustment should be completed.
7 - LCD DISPLAY - A 20-character, four-line, backlit liquid crystal
display used to show menu items and current metal detector operation.
8 - PUSH-BUTTON KEYPAD - A 12-key fully waterproof keypad used to enter
menu selections and to change metal detector settings.
The Series 1200E keypad is mounted externally.
have been retrofit, the keypad may be mounted on the inside of the door.
9 - BALANCE ADJUST ACCESS - This allows access to the balance adjustment
screw.
