• Execute a RUN (start operation) operation command after
the power is turned ON.
• Set the Operation After Power ON parameter to Continue.
• Execute a RUN (start operation) operation command.
• Set the correct channel number.
• Set the correct control output assignments.
• Set the correct set point.
• Set the correct bank.
• Assign the bank of the channel for which the bank is to be
changed to an event input.
