Greenheck
Greenheck's new, fully programmable MSEM energy management starter motor adapts to users' needs. Available in a single phase (up to 15 HP) or in three phases (up to 300 HP) for industrial or commercial applications.
MSEM brings a Hand/Off/Auto keyboard with LCD display for easy adjustment of your settings. It also offers five different input controls including two separate autorun inputs, permissive input, emergency shutdown and firefighter override; two state outputs, under/over voltage and power protection.
For damper control, this model can be specified for 24 VAC or 120 VAC to open the damper when the fans are commanded to start. It also has a limiter switch input to make sure the fan doesn't start until the damper is fully open.
