Notes on the parameter file
The supplied parameter file containing defaults is intended for standard applications and can be
customized at any time. All the functions of the SIMOCODE-DP device can be exploited in full.
The following functions are pre-parameterized and are transferred via PROFIBUS-DP.
Switching the circuit-breaker ON/OFF using the motorized operating mechanism via
PROFIBUS-DP only
If the ON and OFF commands are issued simultaneously, only the OFF command is switched through.
Note: The 3VF circuit-breaker trips in the event of an overload or short-circuit and must be RESET by
issuing the OFF command. Only then can the circuit-breaker be switched on again.
Display of the actual phase current in the highest loaded phase
The default setting current values of 80 % and 120 % are set for the lower and upper current limits
respectively.
Display: 3VF has tripped due to overload or short-circuit
Display: 3VF ON/OFF
