Features
Four protection stages, each of which can be
used for either overfrequency or underfrequency
protection. Any stage can be set out of opera-
tion.
Each protection stage incorporates a rate of
change of frequency function, which can be used
alone or together with the overfrequency/under-
frequency function. When required, the rate of
change of frequency function can be discon-
nected.
Each protection stage is provided with two
adjustable timers
Programmable recovery function
Programmable undervoltage blocking
Programmable rated frequency
Output relay matrix allowing any trip signal to
be linked to the desired output signal
Digital display of measured and set values and
data recorded at the instant of a fault
Reading and writing of setting values via dis-
play and front panel push-buttons, a PC with
setting software, or from higher system levels
over the serial bus
Continuous self-supervision of electronics and
microprocessor operation. On detection of a
permanent fault, the self-supervision system
delivers a control signal to the signal relay and
blocks the other outputs.
