XYCOM XVME-500/1 Gas monitor

The first higher row of the LCD displays the information such as the adjustable values, number of relays, alarm ON/OFF status and voltage level. The keys’ functions are displayed lower, depending of the menu context. When an alarm is activated, an exact failure message appears and the red LED starts blinking. In case of the multiple alarms, all the warning messages are shown sequentially and repeatedly. The green LED is the AC power ON indicator. All parameters can be saved individually. If the keypad has been inactive for 5 minutes, the LCD power save feature shuts down backlighting of the display unit. The charger/rectifier returns to the main menu upon wake-up. The display accuracy is ± 0.5%, ± 1 digit

Recommendation

AC breaker open: verify that the AC breaker is closed ("ON") 

- AC input failure: verify that the AC supply is there and the voltage and frequency are correct 

- DC fuse blown: check out the DC output fuse 

- Bad connection: verify the output and the input connections 

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

- SCR module burnt out: replace the thyristor module(s) 

- High Voltage Shutdown has happened if this option is activated: 1. Investigate the reason. 2. Turn off the AC and DC breakers for 5 minutes, and then restart

DC fuse or breaker blows/trips

- Free wheeling diode failure: check the diode for a short circuit, replace if needed 

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

- Overload: verify the load and the batteries
