  • Page 7: General Warnings And Cautions

    1.2  General Warnings and Cautions You must read and understand the following warnings before installing the Alpha FXM and its components. Fail- ure to do so could result in personal injury or death. • Read and follow all instructions included in this manual. •...

  • Page 8: Certifications And Compliances

    • Never let live battery wires touch the Alpha FXM, the enclosure or any other metal objects. This can cause a fire or explosion. • Never dispose of batteries in a fire. The batteries may explode. Follow the manufacturer’s directions and check with your local jurisdictions for safe battery disposal.

  • Page 9: General Description

    2.1  Overview The Alpha FXM is available in 3 models – FXM 650, FXM 1100 and FXM 2000. The FXM 650 and the FXM 1100/2000 look different, but all of the front panel connectors and circuit breakers operate in the same way. How- ever the circuit breakers for each unit have different ratings.
  • Page 10 Clock” and “Alpha UPS Monitor, Operations, Relay and Load Shed”. For Contact C6, the default factory configuration is +48 VDC output (FXM 650-24 is +24 VDC), but it can be fac- tory configured as a dry contact. Figure 4 shows the contact’s layout while Figure 5 shows the +48 VDC or +24 VDC terminal block layout.

Normally Normally Closed (NC) Open (NO) Common (C) Figure 3 — Contact Layout (Standard for C1 to C5, Factory Option for C6) C1: The C1 contact is energized when line power is unqualified and the Alpha FXM provides backup battery power to the load(s).
  • Page 12 ATS (C8): When the Alpha FXM is in the Inverter mode, this normally open relay closes (Figure 6), sending 48 VDC (FXM 650-48, 1100, 2000) or 24 VDC (FXM 650-24) from the external batteries to this dry contact. If the optional Alpha Technologies’s Automatic Transfer Switch (ATS) is connected, it will cause the ATS to switch the load from line power to the Alpha FXM’s battery backup power.

  • Page 14: Electromagnetic Compatibility (Emc) Requirements

    • In the Generator mode, the Alpha FXM’s range of acceptable input frequency and voltage is expanded to accept the fluctuations created by a generator. See “Operating the Alpha FXM, Sense Type”. Use a generator with electronic speed and voltage controls which produces less than 10% voltage total harmonic distortion (THD).

To change parameters, either click on the On/Off buttons or choose an item from a drop down menu. To execute the changes, click on the Update Settings button. If you do not click this button, the changes will not happen. Unit Configuration Is used to set the name, input, output and how often the GUI polls the Alpha FXM.
  • Page 50 An accurate battery runtime estimation requires the following parameter to be adjusted: •  Peukert Number: Refer to the appendix for information about how to calculate the Peukert number to be entered here. •  Battery Capacity: This is the rated capacity (Ah) of the battery shown on the battery data sheet. Do not con- fuse the battery capacity with the Peukert capacity.
  • Page 51 Relay & Load Shed Is used to configure the front panel’s dry contact to provide a signal for turning off the load. Figure 25 — UPS Maintenance: Relay & Load Shed screen Controlling the external fan by temperature triggered dry contact The Alpha FXM has up to 6 dry contacts (C1 to C6) on the front panel which can be configured by the user to open or close based on the specific trigger conditions.
  • Page 52 Dry contact functions are not programmable through the LCD. Use the RS-232 GUI or the HyperTerminal instead. 2. RS-232 GUI – Figure 26a shows the Relay Configuration window under the UPS Maintenance > Relay & Load Shed screen. As an example, to assign C1 as the Temperature trigger, select Temperature from the drop down menu.
  • Page 53 3. RS-232 HyperTerminal – the Temperature trigger function can be assigned to any available dry contacts as described in "Programming the Dry Contacts" (e.g. c1=11, where 11 is the assigned index for the Temperature trigger function.) After establishing an RS-232 connection with the Alpha FXM at the HyperTerminal screen prompt, type Temp and press Enter to display the current temperature setting (Alpha FXM returns *temp=20).
  • Page 54 A typical application of this timer controlled dry contact function is to control a traffic light. When the grid power fails, the Alpha FXM goes into the Inverter mode and continues supplying backup power to the traffic light. Since the batteries supplying the backup power have limited capacity, a timer controlled dry contact is usually config- ured to switch the traffic light into the flashing amber or flashing red mode after a user-defined period to conserve battery power.
  • Page 55 Figure 31 — Time Of Day Action Status Once the Time of Day Action is configured, the Alpha FXM will automatically disable the timers during the Inverter mode at the defined peak periods. You can switch off the Time of Day Action by setting one or both time period(s) to OFF. The dry contact will be activated by the timer regardless of the peak period settings.

  • Page 73: Testing And Replacing The Batteries

    7.2  Testing and Replacing the Batteries 7.2.1  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, will reduce battery life. For example, an average operating temperature of 27°C will likely reduce the life of the battery by 25%.
  • Page 74 7.2.3  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. 7.2.4 ...
  • Page 75 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.

  • Page 76: Preventative Maintenance

    7.3  Preventative Maintenance Perform preventative maintenance on the Alpha FXM module every 6 to 12 months. For mission critical applica- tions such as backup 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.
