Response at Pre-Warning Level (I>115%I
s
)
The response of SIMOCODE pro can be additionally adjusted in case of overload (disabled,
signaling, warning).
Delay pre-warning (CiR)
The "delay" parameter (default: 0.5 s) is used to determine the interval during which the pre-
warning level (1.15 x I
s
) must be constantly exceeded before SIMOCODE pro executes the
desired response. Otherwise, there is no reaction.
In case of phase failure or unbalance > 50 %, this pre-warning is already issued at approx.
0.85 x Ie.
Reset
If the "Reset" parameter is set to "Auto", the "Overload", "Ov unbalance" and
"Thermistor" faults are acknowledged automatically
●
if the cooling down period has expired
●
if the thermistor value has decreased to the resetting value according to specification.
If the "Reset" parameter is set to "Manual", the errors must be acknowledged by a reset
signal:
●
"Reset" button on the basic unit
●
"Reset" button on the operator panel
●
"Reset" standard functions. For this reason, the "Reset - input" inputs (plugs) must be
connected to the corresponding sockets, e.g. using reset via the bus.
Reset:
Manual, Auto
Note
The "Auto reset" mode of operation may not be used in applications in which an unexpected
restart of the motor can lead to damage to persons or objects.
