GPT ARGUS
Video Level Adjustment (VLA)
The Video-Level-Adjustment (VLA) is used to opti-
mize performance of the Validator. During the VLA
process, the Main Optical Sensors and the Side-
Looking Sensors are adjusted. A VLA is required
• After a Firmware update, which needs hard boot
• Whenever bank note acceptance is degraded
• After the unit is re-configurated to accept
a different size currency
• After preventive maintenance
• After the Validator is disassembled for repair
Note
: The VLA card for the ARGUS G3 is a blank
sheet of coated paper (GPT PN 300E0005 / 70mm
or GPT PN 300E0019 / 85mm). Do not use VLA
cards for the GPT G2 unit (with short instuction printed
on the card) or other cards.
Note
: Do not use damaged or soiled VLA cards for
this test. Please ask Atronic Technical Service to get a
new matching VLA card.
VLA procedure
Note
: If a software update needs a hard boot, per-
form this procedure
directly
after software upload.
1. Power down the Validator.
2. Set DIP-switch 8 & 9 to the "ON" (down) position.
3. Power up the Validator.
4. Wait approx. 5 seconds for Side-Looking Sensors
(SLS) to readjust. The Status LED will illuminate
and remain on when SLS adjustment is completed.
5. Insert the VLA card. The unit will draw the paper
into the currency channel and step it back out.
6. Power down the Validator while leaving the DIP-
switches to "ON" position.
7. Set DIP-switch 8 & 9 to the "OFF" (up) position.
8. Power up the Validator. The Validator now per-
forms a hard boot. VLA procedure is now com-
pleted and the acceptor is ready for use.
Note
: Should a problem occur during the adjustment,
the Status LED will blink 3 times repeatedly.
