Screen save Human sensor
You can select whether the screen saver is deactivated or not when the Human sensor
has detected a man's motion. (Available for the A985GOT only, factory-set to Invalid)
•
Human sensor detection sensitivity
You can select the detection sensitivity of the Human sensor in any of 11 steps, levels 0
to 10, so that the sensor will not detect a motion such as a man passing before the GOT.
(Available for the A985GOT only, factory-set to 10)

•
Human sensor OFF delay
The Human sensor can be turned off when it does not detect a man's motion
after it has turned on. You can set that period between "00 min. 10 sec." and "60
min. 00 sec.".(Available for the A985GOT only, factory-set to 00 min. 10 sec.)
•
Grip switch
You can set whether the grip switch will be used or not.
When the setting is USE, hold down the grip switch and perform operation.
Setup and self-diagnostic operations can be performed independently of the grip switch.
(May be set only for the A950 handy GOT, factory-set to USE)
•
If it is released
You can set whether the touch key pressed on the GOT display will be turned off
or not at the time of grip switch cancel.
At the setting of "NO ACTION", the pressed touch key is turned off when it is
released.(May be set only for the A950 handy GOT, factory-set to KEY OFF)
POINT
•
If the touch panel is not touched within the specified time, the screen saver function switches off the
display to prevent "burn-in" of the display device.
Especially for the display screen type of EL, it is recommended to use this function.
•
Dedicated to the A985GOT, the Human sensor function automatically deactivates the screen saver,
without any touch on the touch panel, by means of a signal detected by the Human sensor.
Using the system information function of the GOT, the signal detected by the Human sensor may also
be controlled by the PLC CPU. For full information on the system information function, refer to the
SW4D5C-GOTR-PACKE HELP function.
Signal detection timings are shown below.

System signal 2
(Human sensor
detection signal)
1) Motion that the Human sensor cannot detect (outside the range or too low moving speed)
2) Detection error of Human sensor (approx. 0.5 sec) + delay due to Human sensor detection sensitivity
3) Human sensor OFF delay time + communication processing time
4) Time when screen saver is being deactivated
5) Human sensor OFF delay setting is required since the Human sensor outputs Detection and No detection
alternately.
6) Human sensor OFF delay + screen save time
