3.1 USM2.5 Configuration (V Models)
The following information affects the use of the USM2.5 module on all V5 and VP versions of
the XM2 Power supply. It should be referenced in place of the information contained in the
relevant sections of this manual.
AC Output Current Monitoring On V5 And VP Models
• The AC current from output 1 of the Power supply is present on Pin 13 of
the USM2.5 transponder connector J3.
• The AC current from output 2 of the Power supply is present on Pin 8 of the
USM2.5 transponder connector J3.
This information overrides the following sections of this manual:
• 4.1 USM2.5 Signal Definition – Figure 4-1 USM2.5 Signal Connections (page
16)
• 4.3 USM2.5 Signal Definition – Name: Output Current #1 (page 18)
• 4.3 USM2.5 Signal Definition – Name: Output Current #2 (page 20)
• 5.1 USM2.5 Operations – USM2 Start Up and Test Procedure 3 (page 21)
Note: The output current pins are swapped on the V5 and VP models in relation to the basic
XM2 models. AC Outputs 3 and 4 are not monitored by the USM2.5 module or V5 and
VP Power Supplies.
AC Output Current Scaling on V5 and VP Models
When monitoring the AC Current of Output 1 and Output 2 on the USM2.5 module position 3
of the Function Switch (SW1) should be set to the ON position in order to gain the correct
output current scaling of 0.4VDC/AAC. This is the case for all V5 and VP models independent
of the issue of USM2.5 module used or the rating of the power supply.
This information overrides the following sections of this manual:
• 3.2 USM2.5 Configuration – Table 3-1 USM2.5 DIP Switch Set-up (page 12)
• 3.2 USM2.5 Configuration – SW1 (3): Output Current Scaling (page 13)
