Sensitivity Adjustment - Omron E2C-CR5B Manual

E2C
Indicators
•
The operation indicator is lit when the sensing object is near the
sensing distance.
•
The stability indicator is lit when the sensing object position is
less than 95% or more than 107% of the sensing distance. The
stability indicator indicates the range in which each sensing
object is detected smoothly.

Sensitivity Adjustment

1. Initial Adjustment
After the E2C Amplifier Unit is turned on, adjust the following Sensor according to the status of each indicator without a sensing object.

Determine S so
that X will be
less than the
maximum
sensing
distance.
Note: If the E2C Amplifier Unit malfunctions due to radical ambient temperature changes, shorten the distance between the Sensor and
sensing object to 80% maximum of the set distance.

Adjustment
Sensitivity
Turn the sensitivity adjuster
counterclockwise so that the op-
eration indicator turns off and the
stability indicator is lit (i.e., the
E2C Amplifier Unit is in mode D).
No adjustment is required.
