A511 User Manual, Rev. 1.1 - 7 - 08/2007
Figure 4: Load settings screen at startup sequence of A511
The A511 has two operating modes:
• The Analog Measurement Mode
• The SDI-12 Sensor Address Changer Mode.
4.1. Analog Measurement Mode
This mode is for measuring analog sensors, which are connected to Ports 1 and 2, and for
solar panels connected to Port 3. By default the A511 will start up in this mode.
In order to see the readings of all three ports you need to toggle between the various
screens as described below.
The way measurements are being taken is corresponding to the settings in the Analog
Measurement Menu as described in section 4.1. By default the device is set to
• no permanent supply – auto-shutdown function of A511 activated
• permanent measurement of sensors
• no Averaging
Caution:
This is the right setting for most sensors, which are capable of continuously updating and
outputting their readings, like temperature or wind speed settings. Since ADCON RTU’s do
not use such a setting, we have also implemented the Adcon measurement procedure,
which can be activated through the Analog Measurement Menu. Certain sensors, like the
Watermark sensor and the WindMAX device, need to be triggered to output a value.
Using the Keypad to toggle between functions and screens
The A511 has a 6-key keypad due to limited space. Thus most keys support at least two
functions. To toggle between functions just press again.
• “F1”: Function 1: shows “Cabling 1 to Cabling 3” (Figure 5)
Function 2: shows “Solar panel measurement” ( 8)
• “F2”: Function 1: shows “Cabling 4 to Cabling 6” (Figure 6)
Function 2: shows “Battery Status & Current Sensing” (Figure 9)
• “F3”: Function 1: shows “Counter and digital input 1 & 2” (Figure 7)
Function 2: will reset counters 1 and 2 (hold key down for two seconds!)
• “SDI Mode”: Switches to “SDI-12 Address Changer Mode”
• “Menu ON”: Function 1: Enters or Exits the Configuration Menu.
Function 2: Shuts the device OFF. Hold key down for two seconds!
