XYCOM XVME-505 Analog input module

- Float, Equalize and/or High Voltage Alarm adjustments are affected. Refer to the adjustment procedures to reset 

- Control board failure: Verify the board condition, and replace if needed Low volts alarm 

- Charger/rectifier overload: Check if the charger/rectifier is in Current Limit mode. Check the load for problems. 

- Input voltage is beyond the limits: Check the input voltage. Under sizing the AC wires can be the cause - Float, Equalize and/or Low Voltage Alarm adjustments are affected. Refer to the adjustment procedures to reset 

- Control board failure: Verify the board condition, and replace if needed - Defective filter capacitor: disconnect the capacitor to observe if there is any change in the output voltage. If so, replace the capacitor

High ripple voltage

 - AC supply voltage is too high: Read the input voltage and rectify the situation 

- Defective filter capacitor: disconnect the capacitor to observe if there is any change in the output voltage. If so, replace the capacitor 

- SCR, Diode or Control board failure: check the components, and replace the defective ones if needed abnormal noise - Check the thyristor(s) and magnetics 

- Replace control board

TYPICAL POWER TRANSFORMER CONFIGURATION

 By default, all standard chargers with a multitap power transformer are configured for 240 Vac input, unless specified otherwise at the time of purchasing. Before you wire ac power to your charger, check the wiring of the main transformer T1, to be sure it is configured for your ac input voltage. Depending on the output power rating, the chargers can accept an input voltage of 120, 208, 230, 240 or 480 Vac. The factory wiring is for 240 Vac by default. By reconfiguring T1, the chargers can accept an input voltage of 120, 208, 230 or 240 Vac.
