TROUBLESHOOTING GUIDE

Check that the load and the supply voltage are the same, and that the total

circuit current is less than 50mA. Slide a screwdriver blade across the face

of the sensor, the input LED should flicker. If not, contact 4B.

If the input LED does flicker, move the front face of the sensor closer to the

target and check the target size as specified under "INSTALLATION".

Either increase the gap between the target and the shaft, or between the

target and the sensor face.

PARTS & ACCESSORIES

The CDL1 and CDL4 devices add additional loads to PLC inputs. The CDL1

is for 110 VAC powered inputs, while the CDL4 (not pictured) is designed

for 24 VDC (NPN and PNP type) low power inputs. Both devices can be

used with the M100 Stopswitch.

Notte: This unit is only neceessary if the PLC input can detect 1mA of current

as a logic High. Please check the PLC input card techincal literature for this

value.
