FKHFN, no checks are performed before manual closing. The following parameters are
then irrelevant.
Address 2SPRGHZLWK0& determines whether closing under asynchronous
system conditions is allowed. Set this parameter to ZLWK7&%FORVH, if
asynchronous closing shall be allowed; the relay will then consider the circuit breaker
closing time before determining the correct instant for the close command. Remember
that closing under asynchronous system conditions is allowed only if the circuit
breaker closing time is set correctly (see above under “Preconditions”)! If you wish to
only permit manual closing under synchronous system conditions, set this address to
ZR7&%FORVH.
The permissible magnitude difference of the voltages is set under address 0&
PD[9ROW'LII. Setting is in volts secondary. When operating the device from a
personal computer using DIGSI
®
4, setting may be in secondary or primary values.
Depending on the connection of the bus-bar voltage (phase–phase or phase–earth)
the phase–phase or the phase–earth voltage is decisive.
The permissible frequency difference between the voltages is set under address
0&PD[)UHT'LII, the permissible phase angle difference under address 0&
PD[$QJOH'LII.
The release conditions for manual closing are set under addresses $ to :
$ 0&6<1&+5 = synchronism check: the bus-bar (Ubus) and the
feeder (Uline) must both be live (/LYH9ROW
7KU, address ); the conditions for
synchronism 0&PD[9ROW'LII (address ),
0&PD[)UHT'LII (address ), and 0&
PD[$QJOH'LII (address ) are checked
before manual closure;
0&8V\Q!8OLQH dead-line check: the bus-bar (Ubus) must be live
(/LYH9ROW7KU, refer to address ), the
feeder (Uline) must be dead ('HDG9ROW7KU,
refer to address );
0&8V\Q8OLQH! dead-bus check: the bus-bar (Ubus) must be dead
('HDG9ROW7KU, refer to address ), the
feeder (Uline) must be live (/LYH9ROW7KU,
refer to address );
0&8V\Q8OLQH = dead-bus and dead-line check: the bus-bar (Ubus)
and the feeder (Uline) must both be dead ('HDG
9ROW7KU, refer to address );
0&25,'( = manual closing is released without any check.
The five possible release conditions are independent of each other and can be
combined.
