Function
An analog 4 to 20 mA signal will be output from amplifier terminals 2 and 8 according to the distance
measured to a target within the 30 to 70 mm measurement range. The output will be locked between 21.8 and
28 mA when the target is beyond the maximum measurement distance. Note: A 10-minute warm-up period is
required from power-up to allow the linear output to stabilize.
The high setpoint output operates according to the high setpoint distance. Rated 80 mA at 30 VDC maximum,
the output with indicator is energized when the target measurement distance is 0.2 mm greater than the high
setpoint distance.
The pass setpoint output operates according to the high setpoint distance and the low setpoint distance. Rated
80 mA at 30 VDC, the output with indicator is energized when the target measurement distance is less than
the high setpoint distance but greater than the low setpoint distance.
The low setpoint output operates according to the low setpoint distance. Rated 80 mA at 30 VDC maximum,
the output is energized when the target measurement distance is 0.2 mm less than the low setpoint distance.
The alarm output operates according to the 30 mm minimum measurement distance. Rated 80 mA at 30 VDC
maximum, the alarm output is energized when the target measurement distance is less than the 30 mm
The sensitivity indicator illuminates when the sensor's receiver is detecting a reflected sonic beam off the
target.
The alarm indicator illuminates when the target measurement distance is less than the 30 mm minimum
measurement distance but greater than the 26 mm uncertain operation measurement distance.
The high range indicator illuminates at the same time the high setpoint output is on.
The pass range indicator illuminates at the same time the pass setpoint output is on.
The low range indicator illuminates at the same time the low setpoint output is on.
The gate input, rated 15 mA at 24 VDC maximum, synchronizes the start of the sonic measurement with the
correct position of the target.
Used to adjust the high setpoint measurement distance and control output. The 4-turn potentiometer allows for

fine tuning of the distance setting. The reference scale above the dial is labeled 30 to 70 mm and marked in

Used to adjust the low setpoint measurement distance and control output. The 4-turn potentiometer allows for
fine tuning of the distance setting. The reference scale above the dial is labeled 30 to 70 mm and marked in
5 mm increments.
In the timer position, a 40 ms OFF-delay is added to the 2 ms response time for the pass setpoint output only.

The high and low setpoint outputs are disabled during the 40 ms OFF-delay.
Input hold switch The input hold function stabilizes target measurement by adding a time delay until the next stabilized sonic
input is received. This minimizes output signal chatter due to unstable input signals from rough surfaces of
changes in target position.
