Description of the Modbus Parameters/Addresses
210 – P3 Status - Error
214 – Status P4 - Error
Adjustable
Range:
Properties:
Stuck contact (error = 1), it is reported when the contacts are already closed when the contactor is turned on, or
when the contacts remain closed when the contactor is turned off. If a contactor coil is de-energized, and within
the "Contactor Timeout" the contact does not open, this error is also generated.
Burnt coil (error = 2), it is indicated when the contactor coil is energized, and the contactor contacts do not close
after the timeout.
Contactor opened (error = 3), it is indicated if the contactor contacts open with the coil still energized.
In transparent mode (error = 4), this error is generated in case of writing in the forward or reverse start commands,
but the respective starter is in transparent mode (see Operating Modes).
Example:
(= 0) No error.
(= 1) Stuck contact.
(= 2) Burnt coil.
(= 3) Contactor opened.
(= 4) In transparent mode.
Modbus addresses 203, 207, 211 and 215 indicate whether there are any alarms in the starter:
203 – P1 Status - Alarm
207 – P2 Status - Alarm
211 – P3 Status - Alarm
215 – P4 Status - Alarm
Adjustable
Range:
5
Properties:
Starter already connected (alarm = 1), alarm generated in case of trying to start a starter that is already on.
Circuit breaker open (alarm = 2), this alarm occurs if a start command is given and the SCW100 identifies that
the circuit breaker remains open. If there is no circuit breaker in the relevant starter, ignore this alarm.
CPU overtemperature (alarm = 3), alarm generated if the microcontroller junction temperature is greater than or
equal to 90 °C (194 ºF).
Example:
(=0) No alarm.
(=1) Starter already turned on.
(=2) Circuit breaker open.
(=3) CPU overtemperature.
