You can select whether SIMOCODE pro is to protect a 1-phase or a 3-phase load. For a 1-
phase type of load, the internal ground-fault monitoring and the unbalance protection must
be deactivated. Phase failure monitoring is deactivated automatically.
1-phase, 3-phase (default)
See also Table "Decoupling module requirements for star networks" in the SIMOCODE pro
system manual.
The "Delay" parameter (default: 0.5 s) defines the length of time for which the prewarning
level (1.15 x I
s
) must be permanently exceeded before SIMOCODE pro will execute the
desired response. If no setting is made, there will be no response. In the event of a loss of
phase or an unbalance > 50%, the prewarning level will be reached earlier, at approximately
0.85 x I
s
.
If the "Reset" parameter is set to "Auto," the "Overload," "Overload + Unbalance," and
"Thermistor" faults will be acknowledged automatically:
● If the cooling down period has expired.
● If the thermistor value has dropped back down to the specified resetting value.
If the "Reset" parameter is set to "Manual", the faults must be acknowledged by a reset
signal:
● "TEST/RESET" button on the basic unit
● "TEST/RESET" button on operator panel
● Standard functions "Reset."
For this, the "Reset - Input" (plugs) must be connected to the corresponding sockets, e.g.
using reset via bus.
Auto (default setting: manual).
Unexpected restart of the motor
The "Auto-Reset" mode must not be used for applications where an unexpected motor
restart may cause personal injury or damage to property.
