The RW pumps do not have E-Stop buttons but have HAND / OFF / AUTO switches at the existing MARCO RTU. For remote shutdown, the plant can be shut down by the operator switching to OFF mode on the Master Plant Control screen. This will stop the RW pumps in operation.
If utility power is lost, the PCS will coordinate restart of the RW pumps when power is restored or switched to standby generator power. The RW pump station has an existing backup diesel generator. Startups of plant equipment are staggered to avoid high amperage draws to the generator. All equipment will restart with the settings at the time of power loss.
