Important Notes

To properly operate the Raindancer Beacon, it has to be connected to an adequate power supply via the POWER-IN field (12/24V DC is recommended). The USB port on the front casing is not suitable.
When a single power supply is used to power both, Raindancer Beacon and peripherals, the GND lines should be tied together.

Power down all systems (Raindancer Beacon, sensors/actuators) before connecting to the Raindancer Beacon via USB, internal components may irreparably take damage otherwise!

Analog Field Section

  • Analog Pins can be individually configured, according to the requirements of the devices to be connected: 0-10V or 4-20mA. By default, all Analog Pins are preconfigured to 4-20mA. An alternate configurations can be set using the web-portal.

Pin Assignment and Value Ranges when Used as Pump Control Unit:

  • The value ranges can be individually adjusted using the web-portal.
A OUT Assignment Default Range
CH 1 Target / Min. Pressure 0 – 16 bar
CH 2 Manually Set Pressure 0 – 16 bar
A IN Assignment Default Range
CH 1 Current Pressure 0 – 16 bar
CH 2 Current Power 0 – 100 kW
CH 3 Current Flow 0 – 100 m³/h
CH 4 Current Speed 0 – 3.600 rpm

Digital Field Section

  • Output can be configured as a permanent or pulsed signal (125ms – 256s). 
    Signal configuration can be adjusted using the web-portal.
  • Pulse counter (using level raise/fall, max. ca. 60Hz), e.g. for water meters on Digital Channel 8.
  • Please note that floating/pulsing input voltages may be transmitted as highly fluctuating input signals, triggering associated actions (e.g. error notification).

Default Pin Assignment and Value Ranges When Used as Pump Control Unit:

D CH Assignment Signal Interpret.
1 (OUT) Control ON Pulse, 125ms ON
2 (OUT) Control OFF Pulse, 125ms OFF
3 (IN) Confirmation Permanent ON/ OFF
4 (IN) Error Code 1 Permanent ON/ OFF
5 (IN) Error Code 2 Permanent ON/ OFF
6 (IN) Error Code 3 Permanent ON/ OFF
7 (OUT) Reset Error Pulse, 2s
8 (IN) Counter Pulse

Error Codes

  • By combining the three main Error Codes using Digital Channels 4 – 6, four additional states, up to a total of 7, can be transmitted.
  • • The textual interpretations of the Error Codes can be customized individually using the web-portal.

Default Error Codes Used by Pump Control/Monitoring:

Code 1
(CH 4)
Code 2
(CH 5)
Code 3
(CH 6)
Interpretation
0 0 0 no malfunction
1 0 0 Malfunction - Pressure, generic.
0 1 0 Malfunction - Motor Temperature
0 0 1 Malfunction - Frequency Inverter / Pump
1 1 0 Malfunction - Low Pressure
1 0 1 Malfunction - Excess Pressure
0 1 1 Restart after Interruption of Power Supply
1 1 1 Remote Control Disabled
