Digital display of measured and set values and
sets of data recorded at the moment when a fault
occurs
All settings may be keyed in using the push-
buttons of the front panel or they may be set
using a personal computer
Continuous self-supervision including both
hardware and software. At a permanent fault
the alarm output relay operates and the other
outputs are blocked
