Low Speed Pulse Config  The low speed pulse output defaults to outputting pulse according to the Low 

Speed Pulse Rate set in the standard Configuration Tab. The pulse output can 
be configured to output gauge status if the low speed pulse output is not 
needed. The choices are shown in the table. 

 

 

Indicates when the current length has exceeded the Length Threshold 
A set point.  This output is reset when the Index Pulse resets.  See the 

Index Pulse/Length Thresholds

 section for details about length 

thresholds.

 

Indicates when the current length has exceeded the Length Threshold 
B set point.  This output is reset when the Index Pulse resets.  See the 

Index Pulse/Length Thresholds

 section for details about length 

thresholds.

 

 

Changes the function of the Direction Digital input. 

When set to Normal, a low voltage on the Direction Input (or leaving it 
disconnected) will cause the gauge to measure a positive velocity and the 
length to count up, and a high (5-24V) voltage on the Direction Input will cause 
the gauge to measure a negative velocity and the length to count down. 

When set to Reverse, the polarity of the digital input is reversed, so a low will 
cause the gauge to measure a negative velocity, and a high (5-24V) will cause 
the gauge to measure a positive velocity. 

Changing the direction will also change the phase of the pulse outputs, 
causing a connected quadrature counter to count in the opposite direction.
