7. Testing the AL05 Ex leakage sensor
WARNING
If the sensor has been or is to be incorporated in an
explosion-proof product, you must not carry out the tests
described below. The intrinsically safe sensor (EN
60079-11) loses the explosions-proof aspect if it is
connected to non-intrinsically safe devices.
The AL05 Ex leakage sensor is integrated in a submerged agitator
and connected to the ALR 20/A Ex leakage sensor relay via two
wires. The relay supplies the sensor with power and receives a
current signal from the sensor. The signal depends on the amount
of water in the gear oil.
The current signal decreases as the amount of water in the oil
increases and is compared to a manually adjustable switching
point. If the switching point is exceeded, the relay switches to fault
mode.
In case of a short circuit or a cable breakage the relay also
automatically switches to fault mode.
Leakage sensor with relay
In order to test the sensor and the relay, measure the current
flowing through the sensor and compare it to the values in the table
below.

TM064366

the relay.
> 11 Too high current

circuited.
Fault
Leakage sensor without relay
If no relay is available or the sensor is to be tested separately, you
can replace the relay by a direct-current supply of 12 V. In this case
a 330 Ω resistor must be added to the circuit.
Now, the measured current is comparable to the table above.
