8.2 8.2.1 Testing and Replacing the Batteries Battery Life Batteries lose their ability to store power as they age. Regularly test the batteries to ensure that they can continue providing reliable service. Battery life is reduced by three major factors: • Temperature – higher ambient temperatures, especially above 25°C (77°F), will reduce battery life. For example, an average operating temperature of 27°C (81°F) will likely reduce the life of the battery by 25%.
PAGE 95
8.2.3 Battery Maintenance The batteries supplied with this unit are sealed and maintenance free. Regularly ensure that all connectors are tight and free of corrosion. The presence of corrosion, swelling of the battery case, or distortion in the shape of the case suggests that the batteries need to be replaced. 8.2.4 1. Battery Conductance Test (Optional) Place the conductance meter probes across Battery #1. 2. Record the voltage and Siemens values in a log book. 3. Repeat for batteries #2, #3 and #4.
PAGE 96
WARNING! Read and understand the battery safety instructions in “Product Safety Information”. CAUTION! Make sure all the replacement batteries are of the same type and rating. Failure to do so could result in improper charging and damage to the batteries. The Alpha FXM cannot provide backup battery power while the batteries are being replaced. If the line becomes unqualified while the batteries are being replaced, the Alpha FXM shuts down and no power is provided to the load. 8.2.5.2 1.
PAGE 97
8.3 Preventive Maintenance Perform preventive maintenance on the Alpha FXM module every 6 to 12 months. For mission critical applications such as backup for traffic intersections, more frequent maintenance should be done. Proper implementation of the following procedure will insure that your system continues to provide reliable backup power in the event of a utility power failure. 8.3.

Appendix A - Puekert Number and Battery Capacity A.1 Introduction The Alpha FXM series UPS units run on batteries when the AC utility power fails. In this mode, the user may want to estimate the remaining time that UPS batteries can supply power to the loads. The battery run time remaining is calculated based on the Peukert equation. Two critical parameters are required for the equation: • Peukert number. • Peukert capacity. The Peukert number and Peukert capacity depend on the battery characteristics.
PAGE 106
A.4 Example The following example shows how to calculate Peukert’s number and capacity from a configured battery string. Consider four Alpha 180GXL batteries connected and configured as shown in the figure below. Two of the four batteries are connected in series, and the two series strings are connected in parallel to the 24 V DC output.
PAGE 107
A.5 Using the Spreadsheet Download the spreadsheet “Peukert’s Parameters Calculator.xls” from www.alpha.ca website. Enter the Battery voltage and nominal load } From the data sheet of the batteries enter the 2 closest currents and discharge hours Enter the number of parallel strings CAUTION! The battery runtime is only an estimation and must not be relied on for critical applications. The battery runtime remaining is applicable only in inverter/backup mode.
PAGE 108
Appendix B - Types of Triggers There are 3 types of trigger: B.1 Edge trigger When the user input changes from one state to the other, the Alpha FXM is triggered to perform Action #1. If the level is set to High, the action will be triggered by a Low to High edge (leading edge). If the level is set to Low, the action will be triggered by the High to Low edge (falling edge).
PAGE 109
Level Alternative When the level is set to High, the Alpha FXM is triggered to perform the next action when the user input changes from Low to High. If the input then changes from High to Low, no action will be triggered because the level is set to High. In other words, only a Low to High user input level triggers an action when Level is set to High. Similarly, when Level is set to Low, the Alpha FXM will trigger an action only with a High to Low user input.
