  • Page 5: Control Inputs

    Connection and wiring Control inputs The control signals are input from the plant controller via floating contacts. The built-in power supply for the starter connects 24 volts DC via the con- tacts to the 3 inputs IN1 to IN3. Four input circuits are available for control. Inputs IN1 and IN2 are used to switch the 3RW22 on and off.

  • Page 19: Cleaning

    Service and maintenance Cleaning The electronic motor control units hardly require any maintenance. ➩ Occasionally the dust should be removed carefully from the circuit boards and the cooling ducts using dry pressurized air or a vacuum cleaner. In heavily contaminated atmospheres it is recommended that after a short operating time, the local pollution level is assessed to deter- mine the date of the next cleaning procedure.
