17. Error Displays and Corrective Actions
■ Error displays during normal operation
• No difference in sensitivity
(during 2 point tuning/AI
tuning/active tuning).
• There is an applied pressure
of ±5 % of F.S. during ambient
pressure compensation.
• There is no sensor head
connected.
• The connection to the sensor head
is broken.
• An excess current is flowing to the
control output.
• Reading is falling below
(exceeding) configuration/display
pressure range.
• Reading is exceeding (falling
below) configuration/display
pressure range.
• The count value exceeds 19999.
• Zero shift timing and threshold
settings are not optimum for
suction detection.
• There were not at least 2 shift
inputs received during AI
tuning/active tuning.
• The pressure for step 2) of the AI
tuning procedure is not higher
Adjust the air pressure device so that
there will be a difference in sensitivity.
Revert to ambient pressure and
readjust sensitivity.
Verify that a sensor head is connected
and turn the power on again.
Check whether the connection to the
sensor head is broken and turn the
power on again.
Check the load and return it to the
rated range.
Return the pressure to the rated
pressure range.
• Return the pressure to the rated
pressure range.
• Reset the count value.
The difference in pressures for a
target object being present and
absent for zero shift timing is too
large. Adjust the settings.
Repeat the active tuning procedure
so that at least 2 shift inputs are
received.
Check the pressure readings when the
target object is present and when it is
Display Cause Solution
* Contact KEYENCE for information about error displays other than those described
above.

*Press
button 5 times while holding down the button to
return the sensor to its default configuration.
Detection mode F-1 general-purpose mode
Operating mode Standard
N.O./N.C. switching N.O./N.O.
Analog/zero shift *1 Zero shift
Chatter prevention 2.5 msec
Power-save Standard
The sensor ships with the following configuration.
15. Default Mode Settings (Initialization)
Key lock disables operation of the sensor's keys.
When the
button is pressed for 3 seconds or more while the but-
ton is being held down, the display will flash and the key lock
feature will be engaged.
This feature disables changes to sensor settings but allows switching of
the display.
*The same key combination will deactivate the key lock feature.

■ Sensor head
■ Amplifier
*1 AP-V41AP/42AP are PNP output types.
*2 The amplifier type with the letter “A” attached on its tail has the count value dis-
play function. Also, the amplifier’s response toward the signals from the head is
faster.
*3 0.1% of F.S. when high-resolution mode is selected.
*4 Max. 20 mA when using expansion units.
