Honeywell MS4103 manual N34 Series MN6134 MN7234

Non-Spring Return Direct Coupled Actuator

N34 Series (MN6134; MN7234)

These direct coupled damper actuators provide adjustable modulating control for air dampers, VAV units, air handling units, ventilation flaps, louvers, and reliable control for air damper applications with up to 7.9 m2/85 sq ft (seal-less dampers; air friction-dependent).

FEATURES

•Control for air damper applications with up to 85 sq ft assuming 3.5 lb-in. per sq ft of damper area, velocity independent.

•Patented self-centering shaft adapter.

•Access cover to facilitate connectivity.

•Declutch for manual adjustment.

•Mechanical end limits.

•Field-installable auxiliary switches.

•Rotation direction selectable by switch.

•Mountable in any orientation (no IP54 if upside down).

•Mechanical position indicator.

•CE approved. UL approved.
