Precautions
!CAUTION
Power supply
Do not impose an excessive voltage on the E2Q2, otherwise it
may explode or burn.
Do not impose AC voltage on any E2Q2 DC model, otherwise it
may explode or burn.
Brown
Sensor
Blue
Black Incorrect
Load
Do not connect the AC types without load to the power supply.
The sensor will be damaged.
Sensor
JINSTALLATION
Power Reset Time
The Proximity Sensor is ready to operate within 300 ms after
power is supplied. If power supplies are connected to the
Proximity Sensor and load respectively, be sure to supply power
to the Proximity Sensor before supplying power to the load.
Power OFF
The Proximity Sensor may output a pulse signal when it is turned
off. Therefore, it is recommended to turn off the load before
turning off the Proximity Sensor.
Power Supply Transformer
When using a DC power supply, make sure that the DC power
supply has an insulated transformer. Do not use a DC power
supply with an auto-- transformer.
Sensing Object
Metal coating: The sensing distance of the proximity sensor will
vary with the metal coating on sensing objects.
JWIRING
High--Tension Lines
Wiring through Metal Conduit
If there is a power or high--tension line near the cable of the
Proximity Sensor, wire the cable through an independent metal
conduit to prevent against Proximity Sensor damage or
malfunctioning.
JMOUNTING
The Proximity Sensor must not be subjected to excessive shock
with a hammer when it is installed, otherwise the Proximity
Sensor may be damaged or lose its water resistance.
JENVIRONMENT
Water Resistance
Do not use the proximity sensor underwater, outdoors or in the
rain.
Operating Environment
Be sure to use the Proximity Sensor with operating ambient
temperature range and do not use the Proximity Sensor outdoors
so that its reliability and life expectancy can be maintained.
Although the Proximity Sensor is water resistant, a cover to
protect he proximity sensor from water or soluble machining oil is
recommended so that its reliability and life expectancy can be
maintained. Do not use the Proximity Sensor in an environment
with chemical gas (e.g., strong alkaline or acid gases including
nitric, chromic, and concentrated sulfuric acid gases).
