FUNCTION
DESCRIPTION
1
V
DIF
Analog Output
This is the difference between the reference voltage and HSU
voltage times a specified gain value. (Range +/-12V, <3mA)
2
GND
Ground for all supplies (system common)
3
V
REF
Analog Input
Reference voltage input (Range +/-10V, <1mA)
Used in calculating V
DIF
.
4
GND
Ground for all supplies (system common)
5
V
HSU
(Standoff)
Analog Output
This is a linearized or optimized voltage representing the
measured tip-to-part standoff distance in millimeters. (<3mA)
Voltage range: -10 to 10V.
This signal will become -10V when a fault occurs with the HSU.
(1mm=1V, or optimized response)
Normal output range: 0 to 10V
6
GND
Ground for all supplies (system common)
7
CAL +
Digital Input
Customer supplied 18 to 30VDC. The CAL input is a request for
sensor calibration. The calibration should take place with the tip
about 12mm away from a grounded metallic surface at least
100mm in diameter. The calibration must be performed at power-
up and preferably every cycle.
When used with “sourcing” output signal, connect:
CAL – to Ground and;
CAL + to Output (18 to 30VDC)
When used with “sinking” output signal, connect:
CAL + to Power (18 to 30VDC) and;
CAL – to Output signal

Output
Common
Connect to customer-supplied GND for sinking outputs or
connect to customer-supplied 5-30VDC sourcing outputs.
