7.17 Protections
The Softstarter has a number of protection functions to
protect the Softstarter, motor and other equipment.
In addition to the type of operations mentioned below,
which are available for all protections, some protections
have more options.
Protections can be enabled or disabled by the user.
The protection parameters can only be changed if the
protection is in operation.
When a protection function senses a risk of damage, the
unit does these actions:
- Protection LED comes ON
- The unit shows the type of event
- The unit stores the type of event in the event list
Protections can be set to have automatic reset or manual
reset. For every protection, there is a parameter called
Operation, which can be set to:
• Stop-Automatic – The engine stops, and resets
automatic when the fault condition is inactive *.
• Stop-Manual – The engine stops, and must be reset
manually when the fault condition is inactive *.
• Off
• Indication
* You cannot reset a fault when the fault condition is
still active. Example: If you set EOL Operation (engine
is too warm) to stop-manual, you can only reset the
Softstarter when the engine to decrease to the correct
temperature.
Protections can be set to an Event group by the Out
parameter. The Event group can be set for relay output to
control other devices in an application
By default all parameters are set to the same Eventgroup.
