Trouble Shooting; General Notices/Maintenance - Elwa ENS 2230 Manual

GETTING STARTED/FUNCTION TEST
After mounting the Water Level Switch WPS 3000 and the sensor, a function
test needs to be made.
Plug the Water Level Switch into a power socket (220....240V/AC) that is
mounted according to VDE. The "power LED" should now be on and green,
showing that the device is ready for use. Now check the function of the sensor
(without attached devices) and the function of the relay. To do this, bridge the
two metal sensors with water or conductive metal. You should be able to hear
the relay switch and the LED "Level" and "Relay ON" should light up. When the
contacts of the relay are free again, the device will reset. Connect the pump
only after the test to avoid "dry" use of the pump while testing,
OPEN/CLOSE RELAY
The relay of the 230 V output can be configured as "open" or "closed":
"Relay ON" (Default)
The basic status of the relay is "open". The output socket has no current. The relay
will switch the output socket "ON" when the water sensor comes into contact
with water. This will then activate connected devices such as pumps or alarms.
The yellow LED "relay" and the red LED "level" will come on. Once the sensor
is not activated any more, the power output will be maintained depending on
the adjusted after-run time and then switch off. Both LEDs will switch off again.
"Relay OFF" (Rel. aus)
The basic status of the relay is "closed". The output socket has a current. The relay will
switch the socket "OFF" (the relay switches and interrupts the contacts), when
the water sensor comes into contact with water. E.g. a container fills with water
and the water flow needs to be switched off when a defined level is reached.
The yellow LED "relay" will switch off and the red LED "level" will switch on.
When the water level falls, the red LED will switch off and the power output will
be switched on again, depending on the adjusted after-run time.
If you are not sure, how to handle the configuration safely, please consult a
specialist for your own safety.

4. TROUBLE SHOOTING

16 | Operation
The device should immediately be disconnected from the mains under the
following circumstances:
– if the device shows any signs of damage
– if the device is not working correctly
– if parts of the device are loose or not assembled correctly
– if any of the wires show signs of damage
In the case that the device needs to be repaired, only original parts may be
used. The use of different components can lead to serious damages. A repair
may only be done by a qualified person.

5. GENERAL NOTICES/MAINTENANCE

H-TRONIC cannot be made liable for consequential damages of any kind,
resulting out of the use of the Water Level Switch. For your own safety and the
safety of your monitored appliances the function needs to be checked regularly.
The Water Level Switch does not need maintenance. When constantly used it
could happen that the sensor tips may become dirty. Therefore it is necessary
to check and clean the sensor on a regular basis (monthly).
MAINTENANCE AND HANDLING
The Water Level Switch is a maintenance free device. Only the electrodes of the
sensor should be checked and cleaned occasionally if the sensor is in constant
use. To ensure a reliable monitoring the function should be tested approx. once
a month, as usually done with all safety devices. To do this, short circuit the pins
at the tip of the sensor with a piece of metal or a drop of water. The switching
of the relay should be heard and the red „LED Rel. Ein" should light up.
CLEANING
Clean the device with a dry cloth only. If it is very dirty use a slightly dampened
cloth. Do not use any solvent based cleaners. Detach the device from the mains
before cleaning it.

We grant warranty of 2 year for this product. The warranty includes the re-
