Gibbons Engineering Group has installed and commissioned a 90kW hire variable speed drive at Northumbrian Water’s Hanningfield site. The project was completed on 16 October 2026 and left the equipment operating in automatic mode.
The existing soft starter and associated connections needed to be reconfigured to accommodate the hire drive. The work covered the motor power connections, mains supply and controls, together with checks of the emergency stop circuit and operational signals.
After isolating and disconnecting the original soft starter, engineers rerouted the motor cables to the hire panel. A new mains cable was installed from the existing motor control panel, supplied through the emergency stop relay.
The team transferred the control wiring to a multicore cable for the new drive controls, removed the existing BC control and mains cables and transferred the running signal from BC to relay RR1.
The drive was then programmed and commissioned. Gibbons checked the emergency stop circuit, running signals and fault signals before leaving the installation in automatic operation.
The case study demonstrates the work involved in integrating a hire drive with an existing motor-control installation. Gibbons provides variable speed drive installation, commissioning and hire support for water-industry and other industrial customers.
