Troubleshooting
11.1.1.21 Valve 2 Failed
The valve V2 could not be switched or is not working correctly.
Solution:
1. Switch to the manual pump mode.
2. Switch on pump P2, and check the function of the valve, switching it on and off.
3. If the valve does not work, check the fuse Q5. To do this open the upper rear panel
of the BMPC/2, the Q5 fuse is located on the upper left side of the BMPC/2 line con-
trol unit. The black Q5 switch must be in the up position.
4. Recheck if the valve works, if it still does not work call Bruker service for assistance.
11.1.1.22 Warning Commercial Power Failed
The input power to the external UPS has failed due to a commercial power failure.
Solution:
If the power failure was not due to a commercial power outage, check the
mains supply chain, perhaps one of the facility fuses has blown.
11.1.1.23 Alarm UPS Low Battery
The backup battery is low and will only supply power for a few more minutes.
Solution:
Reestablish power to the unit (e.g. emergency generator or similar if power is
not available).
11.1.1.24 Warning UPS on Bypass
The UPS is working in automatic bypass mode. This means that the UPS cannot switch
to battery backup mode in case of a power failure.
Solution:
Check the output load of the UPS. If this is too high (load on the NMR con-
sole), the UPS switches to the automatic bypass mode.
11.1.1.25 Warning UPS General Alarm
The warning message for the UPS may vary according to the make and model of the
unit. Read the UPS manual that was delivered with the UPS for information on the
meaning of the general alarm message.
11.1.1.26 Warning UPS Not Connected
The status interface between the BMPC/2 and the UPS is not connected. Therefore the
BMPC/2 will not receive any information about the UPS status. In the event of a longer
power failure no alarm procedure will be activated when the UPS battery fails. Addition-
ally it is not possible to enable the console output.
