smaller allowable currents are used, the contacts may fuse due to surge cur-
rents.
When using a two-wire sensor with a 24-V DC input device, check that the fol-
lowing conditions have been met. Failure to meet these conditions may result
in operating errors.
1. Relation between the FQM1 ON voltage and the sensor residual voltage:
2. Relation between the FQM1 ON current and sensor control output (load
3. Relation between FQM1 OFF current and sensor leakage current:
4. Precautions on Sensor Surge Current
In this example, the sensor’s power supply voltage is used as the input to
CIO 0000.00 and a 100-ms timer delay (the time required for an OMRON
Proximity Sensor to stabilize) is created in the program. After the Completion
Flag for the timer turns ON, the sensor input on CIO 0000.01 will cause output
bit CIO 0001.00 to turn ON.

An incorrect input may occur if a sensor is turned ON after the FQM1 has
started up to the point where inputs are possible. Determine the time re-
quired for sensor operation to stabilize after the sensor is turned ON and
take appropriate measures, such as inserting into the program a timer de-
lay after turning ON the sensor.
