Preface IMPORTANT SAFETY PRECAUTIONS • The XM2 Series 2 Power Supply must only be serviced by qualified personnel. • Use proper lifting techniques whenever handling power supplies, or batteries. • The XM2 Series 2 Power Supply contains more than one live circuit. Even though AC voltage is not present at the input, voltage may be present at the output.
1. Introduction 1.1 USM2 Introduction This Operator’s and Technical Manual will cover the installation, signal definition, operation, and basic troubleshooting for the USM2 (Universal Status Monitor) when used with the popular Alpha XM2 Series 2 Power Supply. This manual also contains detailed information necessary for the successful implementation of the USM2. The USM2 card is a logic controller PCB which may be used to upgrade any XM2 Series 2 Power Supply for the purpose of remote status monitoring.
1. Introduction 1.2 Identification of ‘Old’ Vs. ‘New’ USM2s, continued The “new” USM2 may be easily be identified by the board markings. All new USM2s will have the p/n “704-587-70-00x” with their configuration marked in hand on the PCBA. e.g. “USM2-22”. This marking will be found on a yellow ‘square’ along the bottom right edge of the board. The “old” USM2s will have NO configuration markings on this yellow square and will have a p/n other than 704-587-7000x (e.g. 704-587-29-00x, 704-587-20-00x, etc.).
2. Installation 2.1 Inverter Module Removal and Installation, XM2 The XM2 Series 2 Power Supply comes with a field-replaceable Inverter Module, containing the inverter, battery charger and control logic circuitry. The Inverter Module is designed to accept USM2 plug-in logic upgrades to facilitate remote status monitoring. The Inverter Module can be removed while the power supply is running on line power. With the Inverter Module removed, the power supply will continue to operate in a non-standby mode.
2. Installation 2.2 USM2 Installation, XM2 The optional, USM2 status monitoring upgrade plugs into the XM2 Series 2 Inverter Module. The USM2 can be configured for various status monitoring interfaces by setting two DIP switches and two jumpers. Status monitoring interfaces are listed according to their manufacturer, along with the associated parts in Section 3.1. The USM2 also accommodates a tamper switch assembly to indicate unauthorized enclosure entries.
2. Installation 2.2 USM2 Installation, XM2, continued 3. Setup the USM2 for proper operation (see Section 3, Configuration): a) Before reinstalling the Inverter Module, set the two DIP switches, SW1 and SW2, and the two Jumpers, JP1 and JP2, to the proper configuration settings for the status monitoring interface, as per Table 3-1. Always verify USM2 configuration especially after upgrading or modifying the XM2 Series 2 Power Supply. 4.
2. Installation 2.3 Inverter Module Removal and Installation, XM2V The XM Series 2V power module comes with a field-replaceable, Inverter Module assembly containing the inverter and control logic. The Inverter Module is designed to accept USM (Universal Status Monitor) plug-in logic upgrades to facilitate remote status monitoring. The removable module is located on the front, right-hand side of the XM2V.
2. Installation 2.4 USM2 Installation, XM2V The optional, USM2 status monitoring upgrade plugs into the XM2V Inverter Module. The PCB can be configured for various status monitoring interfaces by setting two DIP switches and two jumpers. Status monitoring interfaces are listed according to their manufacturer, along with the associated parts. The USM2 also accommodates a tamper switch input to indicate unauthorized enclosure entries.

3. Configuration 3.1 USM2 Configuration, continued -3 -3 6: 6: Figure 3-1; USM2 Jumper and Switch Locations Always verify USM2 configuration especially after upgrading or modifying the XM2 Series 2 Power Supply. Function Switch SW1 Reference The following information describes each switch position (1–8) for the DIP switch SW1. SW1 is an eight switch component used primarily to select analog scaling and digital signal polarity for the USM2 card.
3. Configuration 3.1 USM2 Configuration, continued SW1 (4): Output Current #2 Scaling SW1, position 4 is used to select the appropriate scaling for the XM2 Series 2 AC OUTPUT CURRENT #2. SW1 (4) Output Current #2 OFF 0.4VDC/AAC for Output Current less than 20A. ON 0.4VDC/AAC for Output Current equal to or greater than 20A NOTE: • • • In order to represent the proper, 0.
3. Configuration 3.1 USM2 Configuration, continued Function Switch SW2 Reference The following information describes the each switch position (1–4) for the DIP switch SW2. This switch is a four switch component and is used primarily to select/deselect pull-ups to digital signals for the USM2 card. SW2 (1): Equipment Fail Alarm Pull-up Select SW2, position 1 is used to enable or disable the 10k Ohm pull-up to AUX DC on the system’s transponder “Equipment Fail Alarm” pin #6 of J3.
3. Configuration 3.1 USM2 Configuration, continued Jumper JP1 Reference: Auxiliary DC Voltage Select The jumper designated JP1 is used to select the voltage of AUX DC delivered to the system’s transponder. This jumper is configured by removing and placing the shorting connector on to one of the three positions (from the contact designated as “C” for center).
4. Signal Definitions 4.1 USM2 Input Signals and Controls Definition of what is acceptable for HIGH and LOW signal levels used throughout the USM2: HIGH is typically defined as AUX DC Voltage ± 10% (+5VDC, +15VDC, or +24VDC as set by configuration). Voltage exceeding AUX DC is abnormal, but will not likely damage the USM2. (90%AUX DC < HIGH < AUX DC) LOW is typically defined as 0VDC, however any nonnegative voltage between 0VDC and +1VDC will be accepted by the USM2 as LOW.
4. Signal Definitions 4.2 USM2 Output Scaling Voltage USM Output Scaling Results: Defines affect of XM2 operations on the USM2 output scalings. Auxiliary DC Out (J3, pin 2) Auxiliary DC output voltage is selected by JP1 and can provide: +5VDC, +15VDC, or +24VDC. This voltage is used to provide transponder power. Output Voltage level (J3, pin 4) The scaling for 60VAC level is selected by JP2 and SW1(5) which can provide: 0.5VAC, 0.25VDC, or 0.15VDC per VAC output.
4. Signal Definitions 4.3 USM2 Signal Definition This Section provides specific details of all signals (input and output) provided on the USM2’s XPDR and TMPR Connectors when set up as an USM2 (Default setting).

5. Operation 5.1 USM2 Operations USM2 Start up and Test Procedure The XM2 power supply should be fully tested before attempting any USM2 operations. Refer to the XM2 technical manual for details. Once the power supply has been verified as “GOOD” the USM2 can then be tested as follows: 1. Verify the USM2 installation by checking: • Configurations settings of switches and jumpers on the USM2.
6. Troubleshooting 6.1 Troubleshooting the Communications Link Occasionally the communications link between the XM2 power supply and the headend site may appear to break down; updates to and from the power supply may not take place, or data received may be faulty. When this happens isolate and correct the failed elements in a precise fashion to avoid extended troubleshooting times or possibly spreading a potential failure from site to site.
