QUICK BENCH TEST:
Connect Sensor as shown below, then apply Power. When properly connected a soft clicking can be
heard from the sensor and figures will show on the LCD display. Test operation of the LIT25 by holding
the sensor steadily and aiming at a flat, stable target 12 to 28" (305 to 711 mm) away from the end of the
sensor. Allow a few seconds for the LIT25 to lock onto the target before displaying its distance. The
LIT25 will now display range in inches or cm.
Note: The LIT25 will not detect targets beyond the user entered maximum range.
CONNECTIONS:
POWER INPUT: The standard model requires AC power input between 100 to 130VAC 50/60Hz (1
amp fuse is recommended). No adjustments are necessary for any voltage in this range. Option EI rating
is 100-240VAC 50/60Hz. (See OPTIONS section of this manual for connection of optional 24VDC
power input).
IMPORTANT NOTE: To comply with CSA/NRTL standards, AC power input and relay connection
wires must have a water tight fitting conduit entry to the instrument enclosure.
