1st approach
Hardware redesign
New feature: brake 20-Hz voltage while shortage or high
reverse voltage (> 73 V) from generator
Update housing to SIPROTEC 4 (same mechanical data)
New terminal (connector for SIPROTEC 4 with 12 pins);
Attention: The pin numbers have changed their function!
Changing binary input (problem: device version /DD can
produce a 20-Hz voltage temporarily while disable it with
activate binary input)
Increase 20-Hz voltage below load to 26 V
New fuses for operation with permanent auxiliary voltage
AC 230 V
Correction of legend for front and backside
Redesign of binary input (Problem: The binary input blocks
at the hardware versions /DE and /EE the 20-Hz output
voltage automatically if the ambient temperature is smaller
than 0 °C.)
