Hi,
This may sound like a stupid question, but I have been asked to create some PLC logic to control a motor that is wired up on a DOL starter.
The current setup is that the motor is wired through a MCB and contactor, which can be stopped and started via a pair of push buttons.
Currently, the only input to the PLC is the MCB and contactor for that motor (The push buttons are wired directly to the contactor)
There will be two operating modes for this motor; AUTO and MANUAL
What is required is that in MANUAL, the motor will be run via the push buttons. In AUTO the motor will run for a particular set of conditions.
With the current setup, is this possible? (I cannot see how this would be at the minute)
Regards,
