#### 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 |
