Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. The basic models come in both ON/OFF and 2-10VDC options. 2 CAUTION EQUIPMENT DAMAGE! Actuators may be connected in parallel if not mechanically mounted to the same shaft. 5A inductive) @ 250 VAC March 2014 On/Off control Floating Point control WE MAKE IT EASY. 5 Control signal may be pulsed from either the Hot (source) or the Common (sink) 24 VAC line. NEW! ACTUATORS & DAMPERS FAST-ACTING FAIL SAFE ACTUATORS NKQ SERIES DESCRIPTION ACTUATORS & DAMPERS 1 The Belimo NKQ Series actuators are electronic, fail safe, fast acting actuators. They are designed to deliver 4 to 10 second (4 second is standard) fail safe return. March 2014 NEW! ACTUATORS & DAMPERS FAST-ACTING FAIL SAFE ACTUATORS NKQ SERIES WIRING NKQ SERIES Proportional / 4-20 mA INSTALLATION NOTES 1 Provide overload protection and disconnect as required. WARNING: LIVE ELECTRICAL COMPENENTS During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Auxillary switches and feedback options are available on the NKQB24-1 model.

They are not spring return, but rather they are driven by a super capacitor which allows a very fast return to the normal or fail safe position desired. For more customized control, the NKQx-MFT models can be custom ordered based on the options available. The actuator internal common reference is not compatible. 9 For triac sink the common connection from the actuator must be connected to the hot connection of the controller. The NKQB24-SR comes with a feedback of 2-10 VDC standard and the auxillary switch is an optional add-on. A & B should both be closed for triac source and open for triac sink. 4 Position feedback cannot be used with Triac sink controller
