• Calibration SET
NOTE: A TEACH Selection must be selected by programming before TEACH/SET methods can be used.
3.2.2 Response Speed
The DF-G2 can be programmed for one of the following Response Speeds:
Response Speed Display Range Crosstalk Avoidance Algorithm
10 µs (Super High Speed) 0 – 4000 Disabled
15 µs (High Speed) 0 – 4000 Disabled
50 µs (Fast) 0 – 4000 Disabled
250 µs (Standard) 0 – 4000 Enabled
500 µs (Medium Range) 0 – 9999 Enabled
1000 µs (Long Range) 0 – 9999 Enabled
2000 µs (Long Range with immunity to
Energy Efficient Lights)
0 – 9999 Enabled
3.2.3 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 %
10 µs 5 999
15 µs 5 999
50 µs 2 999
250 µs 2 999
500 µs 1 999
1000 µs 1 999
2000 µs 1 999
The offset percent can also be programmed to Minimum Offset. This allows the DF-G2 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).
3.2.4 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 threshold(s) to maintain the programmed Offset Percent from the taught condition.
• After 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 automatically disabled in Calibration SET (see Calibration SET on page 20)
