Troubleshooting
Before analysing possible faults, please check
:
•
that the connectors are properly connected
•
that the operating parameters have the correct values (see the test check-sheet included at the end of
the manual).
There follow some indications regarding possible causes of malfunction and check procedures to be carried
out in order to restore the metal detector to its correct operational status.
Fault
Possible cause
Recommended action
Display off
PW = OFF
Electronics unit fault
Fault in the supply section
Set PW = ON
•
check all the power connections (mains cable, electronics unit - TX antenna
connecting cable, connector J2 on electronics unit)
•
If the power supply voltage is present at the electronics unit (Autotest
procedure or instrument check on connector
J2
, contacts
+/~
and
-/GND
),
replace the electronics unit
•
If the power supply voltage appears at connector
J2
only when it is
disconnected from the electronics unit, replace the electronics unit.
•
check all the power connections (mains cable, electronics unit - TX antenna
connecting cable, connector J2 on electronics unit) .
•
Check that the LED on the ALP card is on.
•
If the LED is off, replace the external
PSA
power adapter.
•
If the LED is on, replace the
ALP
card.
Model with emergency
batteries. Flat batteries
Connect the equipment to the mains supply and recharge the batteries.
Malfunction of ALP card
•
Check the battery voltages. Replace damaged batteries.
•
If batteries are flat, check the recharging section:
•
activate the on/off switch an check that the light on the card is on with
batteries connected and off with batteries disconnected.
•
replace card ALP

check transducer-electronics unit connections
Incorrect programming
· Check that the programming procedure works properly: if not, replace the
electronics unit.
· Buzzer off: set AV>0
If the Metal Detector still does not operate properly, please contact our Technical Department for advice.
