CONTROLS AND ADJUSTMENTS
The timing range is switch selected according to the selection
chart printed on the label. Paste the label on the inside of the
control module's side cover for future reference. The length of
time delay may be varied, within the range selected, by
adjusting the pulse width potentiometer (clockwise = increase).
The selected timing range applies to both LT and DRK delay.

TIMING DIAGRAM:
Condition 1 - DRK delay prevents the output from changing at
the same moment the beam is blocked (DRK).
Condition 2 - LT delay prevents the output from changing at
the same moment the beam is completed (LT).

Slide the numbered switch upward for the "ON" position. In the
example below, 1 and 2 are set to "ON," and 3 is "OFF."
With the installation of a logic card, the control module's
output is governed by the settings of the logic card rather
than the status of the infrared light beam. For the following
timing diagrams, assume that the control module is set for LT
mode operation (beam complete = output on); DRK mode
operation is similar.
Condition 3 - LT and DRK delay can be used together to offset
the output action.
Condition 4 - An event which is shorter than the set delay
period will be ignored and the delay reset.
