Actuator sizing should be done in accordance with the damper manufacturer’s specifications. Control is On/Off from an auxiliary contact or a manual switch. The actuator is mounted directly to a damper shaft from 3/8” up to 1/2” in diameter by means of its universal clamp, 1/2” shaft centered at delivery. For shafts up to 3/4” use K6-1 accessory. A crank arm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft.OperationThe LF series actuators provide true spring return operation for reliable fail-safe application and positive close off on air tight dampers. The spring return system provides consistent torque to the damper with, and without, power applied to the actuator. The LF series provides 95° of rotation and is provided with a graduated position indicator showing 0° to 95°. The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches. Power consumption is reduced in holding mode. The actuator is double insulated so an electrical ground connection is not necessary. The LF120-S US version are provided with one built-in auxiliary switch. This SPDT switch is provided for safety interfacing or signaling, for example, for fan start-up. The switching function is adjustable between 0° and 95°.Dimensions (Inches[mm])2.74" [69.6]2.25" [57.1]0.73" [18.54]3.23" [82]0.25" [6.25]1.15" [29.3]2.3" [58.42]3.15" [80]7.66" [194.501] 0.2" [5.08]0.98" [25] 4.72" [120] 0.39" [10] 1.93" [49]0.26" [6.5] 1.69" [43] 3.66" [93] 6.1" [155] 3.86" [98]LF120-S US - Damper ActuatorOn/Off, Spring Return, 120 VAC, Auxiliary Switch800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 11/29/2017 - Subject to change. © Belimo Aircontrols (USA), Inc.AccessoriesAV6-206.7” shaft extension for 1/4” to 3/4” diameter shafts.IND-LFLF position indicator.K6 USStandard LF clamp (3/8” to 1/2”).K6-1LF clamp (1/2” to 3/4”).KG10ABall joint for 3/8” diameter rod, zinc plated.KG6Ball joint for 5/16” diameter rod, zinc plated.KG8Ball joint for 5/16” diameter rod, 90°, galvanized steel.KH12Univ. crankarm, slot 21/64” w, for 3/4” to 1” dia. shafts.KH6Univ. crankarm, slot 1/4” w, for 3/8” to 11/16” dia. shafts.KH8Univ. crankarm,slot 21/64” w,for 3/8” to 11/16” dia. shafts.KH-LFLF crankarm (with 1/2” diameter shaft pass through).KH-LFVV-bolt Kit for KH-LF.LF-PAnti-rotation bracket LF.SH10Push rod for KG10A ball joint (36” L, 3/8” diameter).SH8Push rod for KG6 & KG8 ball joints (36” L, 5/16” diameter).TOOL-068 mm and 10 mm wrench.ZDB-LFAngle of rotation Limiter for LF.ZF8-LF8x8 mm form fit adaptor for LF.ZG-109Right angle bracket for ZS-260.ZG-110Stand-off bracket for ZS-260.ZG-112LF right angle bracket (4-1/2” H x 5-1/2” W x 2-1/2” D).ZG-DC1Damper clip for damper blade, 3.5” width.ZG-DC2Damper clip for damper blade, 6” width.ZG-LF112LF crankarm adaptor kit (includes ZG-112).ZG-LF2LF crankarm adaptor kit (T bracket included).ZG-LMSA-1Shaft extension for 3/8” diameter shafts (4” L).ZG-LMSA-1/2-5Shaft extension for 1/2” diameter shafts (5” L).ZS-100Weather shield - galvaneal (13” L x 8” W x 6” D).ZS-101Base plate for ZS-100.ZS-150Weather shield - PC w/ foam seal (16” L x 8-3/8” W x 4” D).ZS-260Explosion proof housing.ZS-300NEMA 4X, 304 stainless steel enclosure.ZS-300-5NEMA 4X, 316L stainless steel enclosure.ZS-300-C11/2” shaft adaptor, standard wtih ZS-300(-5).ZS-300-C23/4” shaft adaptor for ZS-300(-5).ZS-300-C31” shaft adaptor for ZS-300(-5).PS-100Actuator power supply and control simulator.ZG-CBLSElectrical junction box for LF.Typical SpecificationOn/Off spring return damper actuators shall be direct coupled type which require no crank arm and linkage and be capable of direct mounting to a shaft up to a 3/4” diameter and center on a 1/2” shaft (default).
