Shutter Overlap:         0.0625 In. minimum at all times. This is normally set to 0.125 In.
Shutter Deadband:     +/- .04 In. to +/- .1 In. (factory set approx. .06 In.)
Shutter Speed:         240 or 375 In. per minute for 60 HZ Power Frequency
200 or 312 In. per minute for 50 HZ Power Frequency
(Factory set to lower speed. Field changeable as required.)

Strip weave speed MUST be less than shutter speed

Typical speed-overlap relationships:

Shutter speed:         240 In. per minute to 375 In. per Min
Normal Overlap:         .125 In. to .185 In.
Minimum Deadband:     +/- .05 +/- .08 In.

Outputs
Relay Contact:     DPDT 2 amp at 115 VAC resistive protection required for other loads.
Derate for incandescent lamp loads with high in-rush (1/10 rating).

Closure Delay:          Approximately 10 milliseconds after detection.
Closure Duration:     Adjustable, approximately 10 to 60 Milliseconds.
Single Pulse:    No holes = 0.0V to -0.6V
Pinhole = +9V

Output Impedance:                       Approximately 100 OHMS
Minimum load Impedance:         Approximately 10K OHMS
Pulse Duration                              Approximately 0.8 Milliseconds
Pulse frequency                            Approximately 500 HZ

Duration of Output Equal to time Pinhole is in inspection zone.
