Pre-alarm delay
The "Delay" parameter (default: 0.5s
) determines the amount of time that
the pre-warning level (1.15 x I
s
) must be constantly exceeded before
SIMOCODE pro executes the desired response. Otherwise there will be no
reaction.
In the case of phase failure or unbalance > 50 %, this pre-warning will
already be issued at approx. 0.85 x I
s
.
Reset
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:
• "Reset" button on the basic unit
• "Reset" button on the operator panel.
• Standard functions "Reset"
For this, the "Reset - Input" (plugs) must be connected to the corresponding
sockets, e.g. using reset via bus.
Warning
The "Auto-Reset" mode must not be used for applications where an
unexpected motor restart may cause personal injury or damage to property.
