These units require a flow switch to monitor motors. If either the duty or standby motor were to fail, volt free contacts would close and an indicator light on the front panel would simultaneously change colour from green to red. The front panel features an ON/Off switch and two dual colour lights to indicate system status.
These three phase auto changeover are built to order. Please phone 01794 874227 and speak to our customer service team for more information.
