Configuration Adjustments
It is possible that the Legacy RTU had special settings. Certain settings will need
to be paged to the RTU from the web portal or by tech support, while others may
not be necessary with the enhanced electronics of the MyDro.
Configurable Settings Shown on the LCD
The following settings may be configured locally on the LCD screen with an
electric key programmed to access the “Config.” screens.
Digital Input Setup:
• Channel: alternate between digital input channels
• Mode:
◦ Dry Contact: no voltage on switched circuit, requires 1000 ohm EOL
resistor parallel to switch
◦ Dry contact NF: no voltage on switched circuit, no EOL resistor
◦ Load sensor: strap on current sensor, no EOL resistor, broken wire, or
failed sensor will show as wire fault
◦ Load Sensor NF: strap on current sensor, no EOL resistor, no wire
supervision
◦ Runtime: for items like pumps where statistics (runtimes, starts, etc.)
are desired. MyDro 150 allows runtime configuration on D1, D2, D3.
MyDro 850 allows runtime on all 8 onboard digital inputs. See main
manual for simultaneous runtime options on input 3 (M150) or input 8
(M850).
◦ Alarm: used for items like floats, where change of state should be sent
in real-time
◦ MyDro 150 configures simultaneous runtimes
• Disabled: No data is sent
• Debounce: Noise suppression feature for 10–90 seconds
Analog Input:
• Channel: alternate between analog input channels
• Mode: 0–5 V, or 4–20 mA
• Filter: consider high filter setting for volatile analog instruments like flow
meters. Filtering is implemented on firmware versions 14.2 and greater.
