the network (see section 4.2).
Check if T-connections are made in the network. T-
connections are not allowed (see section 4.2).
Check the cables and terminating devices (see section
4.2).
Check manual of the display.

Investigate the cause of the blown fuse. Then replace the
fuse (see section 6.2).
Correct the battery capacity setting (see section 5.1.1,
Battery).
Check whether all load and charger connections are at the
load side of the MasterShunt 500 (see section 4.2).
Correct the battery capacity setting (see section 5.1.1,
Battery).
Recharge the batteries for at least 24 hours.
See section 3.1 for an overview of the conditions for a fully
charged battery.
Lower the setting of the float voltage of the MasterShunt
500 by 0.1V (see section 5.1.1, Battery).
Adjust the language setting (see section 5.1.1, General).
Each separate connected device can have its own
language setting. See the user manual of the connected
remote control.
Set the parameters correctly (see section 5.1.1, Alarm
levels).
Increase the delay time (see section 5.1.1, Alarm levels).
Look at your remote control to find out which failure needs
to be corrected.
