4 Laser emission stop input
Disconnecting this terminal from the GND terminal (5, 8, 0) stops
laser emission. Use this terminal in an emergency to stop laser
emission.

6 Synchronous (timing) input
Connecting this terminal to the GND terminal (5, 8, 0) retains the
analog output value just prior to the synchronous input, and stops
laser emission.

7 AUTO ZERO input
Connecting this terminal to the GND terminal (5, 8, 0) resets the
analog output to 0 V (12 mA). The input is a one-shot input.

9 Alarm output (N.C.)
The output contact opens when measurement is impossible due to
an insufficient or excessive light quantity, or due to the target being
out of the measuring range. The output is normally closed.
AA

A NEAR alarm output (N.C.)
The output contact opens when a target is positioned closer than the
measuring range. The output is normally closed.
BB
BB
B FAR alarm output (N.C.)
The output contact opens when a target is positioned further than
the measuring range. The output is normally closed.

E Analog current output
A current of 4 to 20 mA relative to the measuring range of the analog
voltage output of -10 to +10 V is output. A current of 21.6 mA is
output when measurement is impossible.
