Photocell test
(if photocells
are installed)
The display of the electronics unit shows the signal: PI- PO- (see
right) without any object or person passing through the passageway:
the photocells do not "see" anything.
If the test is being carried out on a metal detector that is not fitted
with photocells, press
to pass to the next phase.
PI - PO-
Cover the first photocell relative to the direction of passage (see the
GD
function, Programming section). The display should indicate the
passage of an object through the entrance photocell (PI*).
PI * PO-
Cover the second photocell relative to the direction of passage.
The display should indicate the passage of an object through the exit
photocell (PO*).
Press the
key of the electronics unit.
PI - PO*
Voltage
The electronics unit display shows the DC voltage of the electronics
unit, updating the data continuously (in the example to the right,
31.8Vdc). The correct voltage levels are between 22 and 35 Vdc.
VIN=31.8
