DESCRIPTION
The EBR - 2 enables the user to fill up and drain wells and tanks.
INSTALLATION
WARNING: The installation and assembly of electrical appliances must
be carried out by an authorised fitter or wireman.
The apparatus is equipped with an internal safety circuit to protect it
against interference. However, some particularly strong electromagnetic
fields cause disturbance to operation.
Interference can be prevented if the following installation standards are
taken into account.
- The apparatus must not be installed close to inductive circuits
( motors, engines, transformers, contact units, etc. ).
- It is advisable to provide a separate line for power supply
( where necessary it should be equipped with a filter network ).
- The inductive charges must be provided with interference
suppressors, such as varistors and RC currents.
The cable used for the sensors must be as short as possible. Insulated
2
cabling at least 1.5 mm
. shall be used. If this distance has to be greater
than 100 m. for any reason, or if disturbance is envisaged, it is advisable
that the cable be metal clad, either using earthed, screened cable or a
dedicated metal conduit.
Wires have to be connected to the top part of the probes, assuring a good
connection with the screw.
ASSEMBLY:
It must be installed inside a switch cupboard, with a 35 mm. symmetrical
profile, in accordance with Standard EN 60715 ( Rail Din ).
CONNECTION:
It must be connected in accordance with the following diagram:

DESCRIPTION OF THE SENSORS
Sensor 1: Minimum tank level
Sensor 2: Maximum tank level.
Sensor 3: Located at the bottom of the well or, if metal,
connected to the casing.
Sensor 4: Minimum safety level in the well.
Sensor 5: Minimum service level in the well.
OPERATION
The EBR - 2 enables the user to drain a well until the water level lies
below Sensor 4 (opening circuit 9 - 10), and will not return to service until
the water level reaches sensor 5 (closing circuit 9 - 10). The EBR - 2 will
set the pump in operation (closing circuit 7 - 9), when the level in the tank
lies below sensor 1, and will stop the pump (opening circuit 7 - 9) when it
reaches sensor 2.
STATE OF THE APPARATUS
Tank full ( 9 - 7 open ) Tank led ON.
Tank empty ( 9 - 7 closed). Tank led OFF.
Well full ( 9 - 10 closed) Well led ON.
Well empty ( 9 - 10 open ). Well led OFF.
ADJUSTING THE CONDUCTIVITY
Although the apparatus is calibrated before it leaves the factory, if the
level in the well is above level 5 and the led fails to light up, adjust the
potentiometer in the well until it does light up. If the level in the tank
reaches sensor 2 and the led in the tank fails to light up, adjust the
potentiometer until it does.
If the user wishes to adjust the EBR - 2 more accurately the tank
terminals ( terminals 1 - 2 ) have to be disconnected when the
conductivity is being adjusted. The well terminals ( terminals 4 - 5 ) have
to be disconnected before adjusting the tank conductivity.
