Program Mode
Program (PRG) mode allows the following settings to be programmed in the DF-G1 (refer to diagrams on pages 6-7 for programming).
TEACH Selection
The DF-G1 can be programmed for one of the following TEACH/SET methods:
• Two-Point TEACH
• Dynamic TEACH
• Window SET
• Light SET
• Dark SET
• Calibration SET
NOTE: A TEACH Selection must be selected by programming before TEACH/SET methods can be used.
Response Speed
The DF-G1 can be programmed for one of the following Response Speeds:
Response Speed Display Range Crosstalk Avoidance Algorithm
200 us (High Speed) 0 - 4000 Disabled
500 us (Standard) 0 - 4000 Enabled
2000 us (Long Range) 0 - 9999 Enabled
5000 us (Extra Long Range) 0 - 9999 Enabled
Offset Percent
The Offset Percent is used during the Window, Light, or Dark SET methods. The threshold(s) are positioned a programmable % offset
from the taught condition. The allowable range depends upon the Response Speed Mode, as shown below:
Response Speed MIN % MAX %
200 us (High Speed) 10 999
500 us (Standard) 10 999
2000 us (Long Range) 2 999
5000 us (Extra Long Range) 2 999
The offset percent can also be programmed to Minimum Offset. This allows the DF-G1 to set the threshold(s) as close
as possible to the presented condition, but still provide for reliable sensing.
NOTE: Offset Percent MUST be programmed to Minimum Offset for Dark SET to accept conditions of no
signal (0 counts).
Auto Thresholds
Auto Thresholds can be programmed to be ON/OFF. The Auto Thresholds algorithm continuously tracks slow changes in the taught
condition(s), and optimizes the threshold(s) to provide for reliable sensing. For Two-Point and Dynamic TEACH, the algorithm optimizes
the threshold to be centered between the light and dark conditions. For Window, Light, and Dark SET, the algorithm optimizes the thresh-
old(s) to maintain the programmed Offset Percent from the taught condition.
