Operation
Note : Always leave the system with the Condor (pressure) switch manual over-ride in the “1” (on) position!!
3.4 Battery Size
The HS40 Compact electronics consumes a quiescent of about 12mA and draws about 20A for 30 secs (black Thomas
pump) (30A for 6 secs – blue ARB pump) roughly every 6 hours when the rate at the test orifice is set to 26
bubbles/min delivered to 10m head of water. This averages to: 20A x 30secs / (6hr x 3600secs/hr) = approx 28mA.
The total average current is therefore:
HS40 Compact quiescent 12.0mA
HS40 Compressor average 28.0mA
WL3100 average 5.0mA
Total consumption 45.0mA
A 38Ah battery will run for approx. 38Ah / 45.0mA = 844 hrs = 35 days = 1 month
(without any solar or additional charging)
The battery endurance will be dependent on the following:
§
The consumption of other equipment connected to the battery.
§
The frequency that the system wakes up to take a measurement.
§
The length of time the system is awake for each measurement.
§
The selected bubble rate – the higher the bubble rate, the more often the compressor will be required to replenish
the tank.
§
The water depth – the deeper the water, the higher the pressure in each bubble, the more air in each bubble, the
more air consumed, the more often the compressor will be required to replenish the tank.
§
The battery Ah capacity – the minimum recommended battery capacity is 38Ah.
3.5 Battery Voltage
The battery voltage is monitored during all phases of operation. If the battery voltage falls below 10.0V then all
compressor operation will stop immediately. The battery voltage must then rise above 12.0V before clearing the
battery low condition and restarting the compressor.
