8282A Retriggerable One-Shot Logic Card

INTRODUCTION

The 8282A is an optional logic card for the 80 Series Control

Modules. The 8282A provides a nonretrig-gerable, one-shot

timer pulse, adjustable in three ranges.

By themselves, the control modules allow only a simple on-off

control action through either a triac output or NPN transistor.

Control actions take many forms; start up and shut down

sequences, counting, sorting, or jam detection are some of the

possibilities. The on-off state of the control module's output

depends on the status of the infrared light beam established by

a sensor head. The light beam is either complete (LT) or

blocked (DRK).

The addition of a one-shot timer pulse to a control module's

operation allows a control action to be carried on for a preset

period of time. A nonretriggerable one-shot pulse, once started

by a LT/DRK change, will run through its preset time period

regardless of any further LT/DRK changes.

INSTALLATION

1. Remove the sensor head if installed.

2. Remove the pin guide.

3. Set the appropriate switches for the timing range and

triggering mode desired (see Controls and Adjustments).

4. Orient the logic card so that the adjustment

potentiometer(s) face out.

5. Slide the logic card all the way into the control module and

replace or install the sensor head. Be sure that the sensor

head's bayonet pins line up properly with the logic card's

receptacles. The logic card is connected to the control

module's circuit only when the sensor head is plugged in.

6. Adjustment within the timing range selected can now be

made via the potentiometer(s) on the logic card.
