Control Voltage Monitoring
The control voltage is constantly monitored. If the allowed voltage range is
left, the control voltage for the connected KSM02/KMS02 devices is switched
off and LED H53 emits red light. Thereafter, the motors are coasting down
because a return movement is no longer possible.
Notes on Operation
Do not remove connectors when the component has been powered. Do not
plug in connectors when the component has been powered.
