On-board thermistor temperatureThis register stores the on-board thermistor reading in tenths of degrees C, this is not a calibrated input: divide by10 to calculate the temperature in degrees C. For calibrated temperature inputs, define one of the universal inputsas a temperature input.Modbus Slave ID Modbus Register Description11 * 6081 Battery voltage (mV)6082 Battery charging current (mA)6083 Incoming supply voltage (mV) (solar or power supply)6084 On-board thermistor temperature (⁰C)* The Slave ID for the base board is set at the factory. This may be changed using the base board DIP switch settings.4.3 Working with Solar PowerA reliable solar system requires careful planning and monitoring to size the components correctly. The recommendationsprovided are for the DXM Slave system as an autonomous system.Adding extra components increases the power requirements and likely requires increasing the solar system components.Depending upon the geographical location, the size of the solar panel and battery may vary.4.3.1 Setting the DXM Slave for Solar PowerBy default, the DXM Slave is set from the factory to charge a backup battery from a line power source.4.3.2 Solar ComponentsThe components of a solar system include the battery and the solar panel.BatteryThe DXM solar controller is designed to use a 12 V lead acid battery. The characteristics of a solar system require thebattery to be of a certain type. There are basically two types of lead acid batteries:• SLI batteries (Starting Lights Ignition) designed for quick bursts of energy, like starting engines• Deep Cycle batteries - greater long-term energy delivery. This is the best choice for a solar battery.Since a solar system charges and discharges daily, a deep cycle battery is the best choice. There are different versions of alead acid battery: wet cell (flooded), gel cell, and an AGM (absorbed glass mat).Wet cell batteries are the original type of rechargeable battery and come in two styles, serviceable and maintenance free.Wet cell batteries typically require special attention to ventilation as well as periodic maintenance but are the lowest cost.The gel cell and AGM battery are sealed batteries that cost more but store very well and do not tend to sulfate or degradeas easily as a wet cell. Gel or AGM batteries are the safest lead acid batteries you can use.Battery CapacityDXM100-Sx Wireless Modbus Slavewww.bannerengineering.com - Tel: +1.763.544.3164 15
