A-434 Advanced Photoelectric Sensors
Precautions
Amplifier units
Design
Power ON
The sensor is ready to sense an object within 200 ms after turn-
ing the power ON. If the load and sensor are connected to differ-
ent power supplies, always turn on the sensor power first.
Mounting
Connection/removing of amplifier units
(Connection)
1. Install the units one by one to the DIN rail.
2. Slide one unit toward the other, match the clips at the front
ends, and then bring them together until they "click".
(Removing)
Slide one unit away from the other and remove them one by
one. (Do not remove the connected units together from the
DIN rail.)
Fitting of Mobile Console head
When fitting the Mobile Console head, a 20 mm or more clear-
ance is needed on the left side.
Use of Mobile Console
For the twin output type (E3X-DA##TW), up to 16 channels
(eight E3X-DA##TW units) can be set from the Mobile Con-
sole E3X-MC11. (Note that the operation mode and area de-
tection cannot be set.)
Adjustment
Mutual interference prevention function
The digital display value may vary due to the light from the
other sensor. In that case, low the sensitivity (raise the thresh-
old) to stabilize detection.
EEPROM Write Error
If a write error occurs (operation indicator starts flashing) due
to power-off, static electricity or other noise in the teaching
mode, perform teaching again.
Optical communication
When connecting the amplifier units, assemble them in close
contact. During operation, do not slide or dismantle the ampli-
fier units.
Hysteresis adjustment
The Mobile Console allows hysteresis adjustment, but note
that the unit may not operate properly if the hysteresis setting
is lower than the factory value.
Correct Use
Note:1 .When the amplifier units are connected to each other, the
operable ambient temperature changes depending on the
number of connected amplifier units. Check "Ratings/Per-
formance".
2 .Before connecting or removing the units, always switch
power off.
