Menu misc.
In this menu option, setting of additional protective param-
eters is carried out.

misc. mem: enablinganddisablingofthethermalmemory
misc. phasl: enabling and disabling of the phase-failure
sensitivity
misc. syml: here, the operate value for permissible cur-
rent unbalance of the phases is determined.
Theadjustable valuesarein the rangeof 5 to
50 % or "off". If the menu option relay opt is
enabled,onoccurrenceoftheparameterized
unbalance, the output "optional signal" is set
andthe circuit-breaker istrippedafter elapse
of the delay time set under relay tx.
misc. symU (only possible with measurement module and
voltage transformer): here is set the operating value for the
permissiblevoltageunbalanceofthephasesfortheextended
protectivefunctions.Theadjustablevaluesareintherangeof
5 to 50 % or "off". If the menu option relay opt is enabled, on
occurrence of the parameterized unbalance, the output "op-
tional signal" is set and the circuit-breaker is tripped after
elapse of the delay time set under relay tx.

_on: here is set the operate value for load restoring.
The adjustable values are in the range of (50 % to 150 %) x Ir
or "off". (only possible with additional functions 2)
Caution
The signal is only active after elapse of the
delay time set under menu option Relay tx.
Note:
If the signal "advance a_trip" is to be used, this
parameter must be set to off.
Caution
The signal is only active after elapse of the
delay time set under menu option Relay tx.
