ZelixLow-torque, Spring-return Direct-coupled
Actuator (DCA)

• Direct Coupled Actuators
• March 2009

2
Zelix Major Benefits

• Smaller actuatorfits well on smaller dampers and
  in tighter installations
• Self-centering shaft adaptorreduces installation
  time
• Improved integral end cap
• Reduced material costsno need for J-box
• Very efficient for replacement businessno need
  to disconnect electrical to swap actuator
• Mode selectorreduced inventory by allowing
  control signal selection

Zelix Expands the Portfolio

• Launches during the Momentum ConferenceMarch 30,
  2009
• Expands portfolio to lower torque levels
• 3 Nm 5 Nm (27 44 lb-in)
• 44 lb-in DCA will replace existing, larger-sized
  DCA
• 88 and 175 lb-in DCA will still be available

Zelix Control Modes

• MS81XX 2-position, low voltage (24 Vac/dc)
• MS41XX 2-position, line voltage (120/230 Vac)
• MS75XX Floating/Modulating
• 0-10 Vdc, 10-0 Vdc, 2-10 Vdc, 10-2 Vdc, Floating
  (forward), Floating (reverse)
• MS74XX Floating/Modulating/Economizer
• 2-10 Vdc, 10-2 Vdc, Floating (forward), Floating
  (reverse), 3 kOhm NTC, 3-position

Zelix Economizer ControlMS74XX

• MS7403 and MS7405 actuators can control damper
  using 3-position or 3 kOhm NTC control
• 3-positon control can provide retrofit solution
  for M8504/W7459C system. Still requires use of
  W7459C economizer module
• Minimum position set on DCA using minimum
  position potentiometer
• Requires use of a foot-mount accessory kit
• 3 kOhm NTC control can provide retrofit solution
  for W7459A/M7415 economizer system
• The minimum position potentiometer is only
  enabled on the 3 kOhm NTC or 3-position
  modesdisabled for modulating and floating
  control modes to conform to energy codes
• No internal auxiliary end switch option on the
  MS74XX series of Zelix
