Operating voltage d5 V DC
The display goes on when voltage is supplied to the control electron-
ics.
Alarm displays 1 and 2
The displays indicate the switching status of the signal outputs:
- display 1 goes on when signal output 1 is set.
- display 2 flashes as soon as output 1 is set and remains illumi-
nated when signal output 2 is set (only when signal output 2 is
configured).
Both displays flash during system adjustment.
LED illuminated bar
The LED illuminated bar indicates the signal level. In normal opera-
tion, one or several green LEDs are always illuminated. If the web
moves a foreign metal object across the probe, the yellow and red
LEDs go on. The larger the size of the metal particle, the greater the
number of LEDs that light up.
The maximum signal value is temporarily stored so that even fast
signals may be stored, i.e. once the metal particle has passed over,
the LED that had indicated the maximum value, remains illuminated.
Then the LEDs to the left go on one after the other until only the
green LEDs are illuminated.
All LEDs light up (approx. 60 sec.) during a system adjustment. Once
this has been completed successfully, only one or several green
LEDs are illuminated.
Alarm indicators on the side frame
The alarm indicators on the side frames of the metal detector shine
when signal output 1 is set.
Increase/decrease value keys
In normal operation these keys are used to increase or decrease the
sensitivity of the metal detector.
In setup mode, the parameter numbers or values are increased or
decreased.
RESET key
Use this key to reset signal output 1 provided that the metal detector
is configured accordingly. The key has the same function as the in-
puts of the same name.
SETUP key
On its own, the setup key has no function.
In conjunction with the increase/decrease value keys, setup mode
may be called up and the metal detector parameter values displayed
and changed.
