Cold start
Description
The "cold start" function enables control of a motor without error messages. The motor
starter responds here as if the main power supply were connected to the system. Thus, in
the commissioning phase, for example, the relevant control commands are accepted from
the controller and the relevant messages are sent.
The "cold start" function enables activation of the motor starter without a main power supply.
The motor starter responds here as if the main power supply were connected to the system.
The error message "Residual current detection/tripping" is suppressed. Thus, in the
commissioning phase, for example, the relevant control commands are accepted from the
controller and the relevant messages are sent.
Note
The "cold start" function is not possible for the command "Motor on" in an ATEX
configuration.
Note
If the main power supply is nevertheless present (current flowing), an internal trip command
is generated.
Note
The "cold start" action is only permissible as an "input n level" (NO contact) and only as an
"input n signal" (non-retentive).
You can activate the "cold start" function as follows:
●
PIQ 0.7 "Cold start"
●
Via the 3DI/LC module
●
In manual bus mode via DS68
