How does the control box function?
Many clever procedures, checks and measurements are performed in the control box. Here is a brief
description of what the control box is trying to accomplish while it is activating an application:
• Safe activation of the application
* Parallel, even movement of all columns in the application is critical.
- The control box does not directly know the position of each column. Instead, the position of
each column is constantly calculated via Hall pulses from each motor.
- Motor cable disconnections are also detected as errors.
* If PIEZO technology is present in the column, the control box monitors for PIEZO “collision”
signals from each channel. When a PIEZO signal is sensed, movement is immediately stopped
and, if there is room, the system is ran in the opposite direction a small distance.
* Anytime the control sees an incomplete signal, or more than one signal (multiple keys pressed,
multiple desk panels activated at the same time), an error is determined and no movement is
allowed at that moment. This is to prevent an action of movement that is not intended by the
user.
• Protection from equipment damage
* Internal temperature of the control box is monitored.
* Maximum current draw for each motor channel, as well as the system as a whole, is measured.
When the current exceeds an allowable limit, an error is presented.
