AC Charging System Test
If your system setup includes an AC Charger connected to the XRC Board, and it is not
supplying the required voltage to the unit, you may need to test the AC Charger. The
following instructions contain the steps required to do so.
Instructions
Step
Procedure
1.
Check DC wiring to
XRC termination block connector J17 (see
Figure 5–5). Be certain wiring is correct.
Correct and retest as necessary.
2.
Check input AC power supply voltage to external AC charging
unit. Be certain primary AC voltage is correct.
Correct and retest as necessary.
3.
If primary AC voltage input level is correct, wiring to
XRC-195
Board terminal is correct and there is no DC output from the
charger, replace charger fuse (see Figure 5–5).
Correct and retest as necessary.
4.
If fuse is not faulty or there is no charger DC output voltage after
replacing fuse, replace AC charging unit.
Correct and retest as necessary.
5.
If a issue still exists, return to the Power Troubleshooting
flowchart and continue testing.
