Figure 84: Change of rotation
Example for accessories required:
S3 = M22-WRK... selector switch with three switch positions
Q31 = DILA-22(...) contactor + DILA... auxiliary contact module
When in the R position (FWD), S3 will use contact 23/24 to apply the enable
signal ① to the DS7 soft starter (+A1 control signal terminal). The rotation is
reversed with S3 via the zero position (off) to position L (REV).
The contactor Q31 is activated and switches the enable signal ① via the
auxiliary contact 53/54 to the DS7 soft starter (control terminal +A1).
