Menu misc.
In this menu option, setting of additional protective param-
eters is carried out.
misc. ZSI: enabling and disabling of the short-time grad-
ing control
misc. I 2 t : enabling and disabling of the I
d
characteristic of the short-time grading con-
trol
misc. I 2 t : enabling and disabling of the I
d
character of the earth-fault protection
misc. mem: enabling and disabling of the thermal memory
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.
The adjustable values are in the range of 5 to
50 % or "off". If the menu option relay opt is
enabled, on occurrence of the parameterized
unbalance, the output "optional signal" is set
and the circuit-breaker is tripped after 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
permissible voltage unbalance of the phases for the extended
protective functions. The adjustable values are in the range of
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.

misc. EF (only possible with measurement module and volt-
age transformer): here is set the operating value for the
permissible reversed energy flow direction for the extended
protective functions. The adjustable values are in the range of
-2000 kW to 2000 kW or "off". If the menu option relay opt is
enabled, on occurrence of the parameterized unbalance, the
output "optional signal" is set and the circuit-breaker is tripped
after elapse of the delay time set under relay tx.
misc. f< (only possible with measurement module and voltage
transformer): here is set the operating value for underfrequency
for the extended protective functions. The adjustable values are
in the range of 15 Hz to 500 Hz or "off". If the menu option relay
opt is enabled, on occurrence of the parameterized unbalance,
the output "optional signal" is set and the circuit-breaker is
tripped after elapse of the delay time set under relay tx.
misc. f> (only possible with measurement module and volt-
age transformer): here is set the operating value for overfrequency
for the extended protective functions. The adjustable values are
in the range of 15 Hz to 500 Hz or "off". If the menu option relay
opt is enabled, on occurrence of the parameterized unbalance,
the output "optional signal" is set and the circuit-breaker is tripped
after elapse of the delay time set under relay tx.
misc. U< (only possible with measurement module and volt-
age transformer): here is set the operating value for undervoltage
for the extended protective functions. The adjustable values are
in the range of off, 100 V to 1000 V or "off". If the menu option relay
opt is enabled, on occurrence of the parameterized unbalance,
the output "optional signal" is set and the circuit-breaker is tripped
after elapse of the delay time set under relay tx.
misc. U> (only possible with measurement module and volt-
age transformer): here is set the operating value for overvoltage
for the extended protective functions. The adjustable values
are in the range of 100 V to 1250 V or "off". If the menu option relay
opt is enabled, on occurrence of the parameterized unbalance,
the output "optional signal" is set and the circuit-breaker is tripped
after elapse of the delay time set under relay tx.
misc. I _off: here is set the operating value for load shedding.
The adjustable values are in the range of (50 % to 150 %) x l r
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.
misc. I _on: here is set the operate value for load restoring.
The adjustable values are in the range of (50 % to 150 %) x I r
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.
