User Interface

The VelociTach motor control board’s on-board user 
interface is easy to use and supports:

Verification/auditing of on-board parameter settings 
(read-only)

Adjustment of the on-board settings (write)

The user interface has three input buttons (see 

Figure 79

), 

from left to right:

“Menu/Set”

“Decrement”

“Increment”

Each button has several different actuation levels 
depending on length of press, and what the UI is currently 
displaying.

Indicates the status being calculated or Fan Motor 1. If “off,” 
this indicates that either:

1) No fan speed is being requested or

2) The fan performance is failing to meet the request; refer 
to 

“ECM Motors,” page 148

 for additional troubleshooting 

information.

If “on,” this indicates that the fan is performing correctly and 
will be used to report fan status correctly, depending on
