Banner DF-G3 Long Range Expert User Manual

3. If the
ber opc array is contaminated enough that the auto compensaon tracking algorithm cannot suciently adjust the
thresholds to ensure reliable detecon
4. If the
ber opc array is blocked for more than 2 seconds
Return the system to normal operaon by cleaning the ber opc array and performing a Window SET to reset the clear-state light level
(see Window SET on page 19).
Complementary Programming
When CH2 is selected for Comp (Complementary) operaon, its output always switches to the opposite state of CH1.
3.2.2 TEACH Selecon
The DF-G3 can be programmed for one of the following TEACH/SET methods:
•
Two-Point TEACH
• Dynamic TEACH
• Window SET
• Light SET
• Dark SET
• Calibraon SET
Note: A TEACH Selecon must be selected by programming before TEACH/SET methods can be used.
3.2.3 Response Speed
The DF-G3 can be programmed for one of the following Response Speeds:

3.2.4 Oset Percent
The
Oset Percent is used during the Window, Light, or Dark SET methods. The threshold(s) are posioned a programmable % oset
from the taught condion.
The allowable range is 5% minimum to 95% maximum for all response speeds.
The
oset percent can also be programmed to Minimum Oset. This allows the DF-G3 to set the threshold(s) as close
as possible to the presented condion, but sll provide for reliable sensing.
Note: Oset Percent MUST be programmed to Minimum Oset for Dark SET to accept condions of no signal (0 counts).
3.2.5 Auto Thresholds
Auto Thresholds can be programmed to be ON/OFF. The Auto Thresholds algorithm connuously tracks slow changes in the taught
condion(s), and opmizes the threshold(s) to provide for reliable sensing. For Two-Point and Dynamic TEACH, the algorithm opmizes
the threshold to be centered between the light and dark condions. For Window, Light, and Dark SET, the algorithm opmizes the
threshold(s) to maintain the programmed Oset Percent from the taught condion.
• Aer programming Auto Thresholds to ON, it is highly recommended to re-perform the TEACH/SET method
•
Manual Adjustments are disabled when Auto Thresholds are ON
• Auto Thresholds are automacally disabled in Calibraon SET (see Calibraon SET on page
23)
• Severe contaminaon/changes in the taught condion can prevent the Auto Thresholds algorithm from opmizing the
threshold(s). If this occurs, the
DF-G3 enters a Threshold Alert or Threshold Error state. See Troubleshoong on page 25 for
more explanaon.
