Error 3/9

Error detection for errors "3" and "9" can be activated/deactivated in the "Error 3/9" menu. The
following settings are possible:
Configuration
"Errors 3+9 off"
(factory setting)
"Both on"
"Error 3 off"
Fig. 47: Current output in the event of an alarm
1 Current output without errors "3" and "9",
output: 20.5 mA (NAMUR NE43)
2 Current output with errors "3" and "9", the
output switches to alarm status (21 ... 23
mA, configurable)

Function
If the set measuring range is overshot by more than 3.125 %, the current
output will maintain the 20.5 mA it will have reached by this point until the
flow returns to a level below the upper range value set for the measuring
range.
If the set measuring range is overshot by more than 3.125 %, the current
output will switch to the set fault current (factory setting 22.4 mA). If
QmaxDN is overshot by more than 20 %, error "9" will also be output as a
warning before the device is overloaded.
If the set measuring range is overshot by more than 3.125 %, the current
output will maintain the 20.5 mA it will have reached by this point. If
QmaxDN is overshot by more than 20 %, error "9" will also be output and
the current output will switch to the set fault current.
