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 "optional 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 voltage
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 voltage
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 voltage
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 voltage
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.

relay g:
on - exceeding the operate value of the earth-fault protection leads
to trip
off - exceeding the operate value of the earth-fault protection
activates the earth-fault LED. Indication can only be reset by
pressing the CLEAR button after the operate value has been
undershot
This is possible only on overcurrent releases E/F, J/K and P.
relay temp:
on - exceeding the temperature limit in the release enclosure
activates the optional signal and the temperature LED (the
optional signal must be enabled by the relay opt. menu option)
off - exceeding the temperature limit in the release enclosure
activates the temperature LED
relay opt.
on - the optional signal is activated if at least one of the enabled
causes is present (I.E. misc. syml or relay temp) and the
circuit-breaker is tripped after elapse of the delay time set
under relay tx.
off - optional signal and optional tripping are disabled
