The AquaVent 3500 SPX Wellhead contains a multicolour LED.
A properly addressed MODBUS command is acknowledged by a single Yellow flash. A normal MODBUS response is indicated by a single Yellow flash. A MODBUS Exception response is indicated by a single Red flash (see Section 4.5.3 for Exception response codes).
The following will occur during power up:
Tricolour spin (3 cycles) to indicate a power-on event.
Upon entering Field mode, a rapid 10 cycle alternation of Yellow/ Green colour indicates that communication has been established with the AquaVent logger, and is running with the Baud rate and MODBUS device address prescribed by the AquaVent settings (which can only be changed by Solinst Levelogger PC Software).
Upon entering Field mode, a rapid 10 cycle alternation of Yellow/ Red colour indicates that the Wellhead has come online WITHOUT establishing communication with the AquaVent logger, and is running with the default Baud rate and MODBUS device address. (Check the batteries and the connections to your AquaVent logger).
