Introduction
This guide will allow you to program the show and service positions of your projector lift.
To program the projector lift, you will need to know:
1.
The Show position
2.
The Service position
or fully lowered position
The following information is needed to calculate the rate at which the lift lowers (e.g.
mm/sec). If the information below is absent, the rate can be calculated by timing the projector
travel from the home position to the service position (fully lowered)
3.
Motor tube diameter
4.
Motor rpm or turns/min
A few calculations will enable you to calculate the
Show position
as a percentage of the total
drop. It will also let you work out the equivalent time (in seconds) for the lift to get to the
Service position
(ie. Fully lowered). See illustration below.
