7. Prox sensor: The prox sensor communicates the position of the sampler assembly to the
external controller for automatic cycling functions. Adjust sensor to 3/8 to 1/2" (9-14 mm)
gap. Cycle unit manually to insure that this gap is maintained throughout cycling range.
Red LED light should light whenever prox sensor is near metal and not light when away
from metal. To view LED light, shade ambient light from prox sensor and cycle sampler
assembly manually. Be careful to not strike or damage prox sensor face. NOTE: in manual
mode, hydraulic cylinder opens and closes completely; in automatic mode cylinder stops as
soon as prox sensor clears upper and lower plate. In order for cylinder to set electrode-
shoe clearance properly (step 2 above), adjust prox sensor height with sampler shoe
completely raised. Adjust the prox sensor so it barely clears the lower part of the sensor
plate when sampler is completely raised. It may be necessary to reposition the electrode
holder after adjusting prox sensor; see step 2 above.
