Macros

Motion –

If System Power is On - The system off countdown timer is stopped and reset.

If System On is Off - The lights go on.

No Motion –

If System Power is On - The system off countdown timer runs. If this timer reaches zero, a system off Macro

is called, shutting down the system.

If System Power is Off - The lights go off.

A 2K ¼ watt resistor is used to create an off state for the occupancy detector. When the occupancy detector

is off, its output floats causing the TEK 1 to think it is on. Placing this resistor between the input and ground

creates an off state for the occupancy detector.

If the TekControl software is running on the room’s PC, a message can be displayed that the system is

about ready to shut down. This allows the user to reset the system timer from the PC. Lights can also be

controlled by the user from the PC.

This method of controlling the lights from the TEK 1 solves the problem with the lights automatically shutting

off when there are only a few people in the room. Also, the TEK 1 can power off other devices when no one

is in the room, thereby saving energy and extending the bulb life of a video projector

Note that when using a Digital Output to control a lighting power pack, the logic is reversed. This means

when power is first applied to the TEK 1 the Digital Output is in an open state, causing the pull-up resistor to

supply current to turn on the power pack. Once the TEK 1 is running, a command is issued to turn on this

output causing the power pack to go off. Using a relay solves this problem.
