Section 7: HELP-Functions / actual output assignment
The BR7000 features a context related help function.
For each menu item one or more help pages are available which can be accessed directly
with the HELP-button. Scrolling is done with "UP/DOWN" buttons, back retrace with
ESCape.
In automatic operation (= = =AUTO-MODE= = =) 9 help pages are available. The first
pages explain the general meaning of used symbols.
On the help pages 7…9 the actual assignment of the internal relay outputs
K01…K15 to the phases and to the capacitors are shown directly.
This table depends on the CONTROL-MODE that is set and will change
automatically.
The assignment shown here is not trivial, especially in CONTROL-MODE 2
(MIXED MODE) and must be obeyed without exeption!

Section 8: ALARM RELAY / ERROR MESSAGES
The contact of the alarm relay (K21) is closed during normal operation and opens in
case of failure. At the same time, the respective error is indicated in plain text in the
display:
UNDER COMPENSATED
- display and relay
missing reactive power
OVER COMPENSATED
- display and relay
OVER CURRENT
- display and relay
MEASURING VOLTAGE ???
- display and relay
OVER TEMPERATURE
- display and relay
OVER VOLTAGE
- display and relay
UNDER VOLTAGE
- display and relay
HARMONICS
- display and relay
Additionally, several messages for different operation states are generated. An individual
adjustment resp. masking of single messages is possible in EXPERT-MODE 2.
During masking, the display of message, the eventual output via alarm relay and possible
influcences on the control process are suppressed.
