Sonar-BERO K65
Operating Instructions
Application (Fig. I)
The Sonar-Beros of compact range K65 are supplied ready for use. They are designed for DC voltage. Their housing design and functionality
means that they are suitable for level detection applications in small containers or tanks. The devices have 2 switching outputs (S
S ). One distance can be assigned to each of them. for example, the minimum and maximum levels in a tank can be evaluated and
max
displayed. The parameters can be programmed with SONPROG or with an automatic setup (Teach-In). They cannot be combined with
the evaluation units of modular range 2 (3RX2110).
Mounting and Connection (Fig. I / III)
All parts are accommodated in a fully enclosed housing. The ultrasonic transducer is set back approx. 10mm in the housing, so it is
protected. Because of the built-in sealing the BERO can be used as a closure with integrated level detection. The opening of the
tank must have a diameter of 26mm. The BERO is fixed by means of two M5 screws.
The BERO has a 5 pole M12 connector. Standard 5 pole plugs, such as 3RX1584 (with terminal compartment) or 3RX1630 (with 5 m
PUR cable), can be used. The BERO has built-in polarity reversal as well as short-circuit and overload protection. Where there is
electrical interference, shielded cables are recommended.

Setup (Fig. I / II)
The two ranges, the associated hysteresis and the average value are preset at the factory (see technical data). The parameters can
be programmed with SONPROG or with an automatic setup (teach-in). Teach-in can be done by means of the keys of the interface
3RX4000 or via the teach-in pin XI (pin 2) of the connector.
a.) Automatic Setup (teach-in)
With this function the minimum level S
• Fill the tank up to the required minimum level or place an object at the required distance.
• Apply "low" signal (0 to 3 V) to the pin XI (pin 2) of the M12 connector.
(e.g. connect pin 2 via a key to 0 V, or connect it via a PLC to "LOW")
The LED "S " is blinking. The BERO is disabled; it's learning the distance;
min
• The signal duration must be at least 150 ms.
• Remove signal from XI.
(e.g. disconnect it from pin XI, connect it to U
Important! As long as the signal XI is "low", the BERO is disabled.
