|Industrial-Duty Hoist/Jackshaft Operator with Internal Door Lock Sensor –|
Model DHJ is an industrial-duty hoist/jackshaft operator with an internal door lock sensor. It features a removable hinged electrical box cover, a continuous-duty high-starting torque motor, a universal-mount frame design, industrial ball bearings on the output shaft and an emergency chain hoist with electric interlock.
LOGIC 4.0 TECHNOLOGY (L4)
Reliability & Programming Simplicity
Available Plug-in Options for Logic 4.0 (L4)
Auxiliary Contact: Used to operate security, warning, heating or other 5V to 240V devices. Features both normally open and closed contacts that actuate in conjunction with limit switches.
TLS1CARD: Provides seven field-selectable modifications, including six door traffic control options. Combines with Logic 4.0’s standard Timer-to-Close feature to offer timed, sequenced activation of warning lights, sounders, and other devices (sold separately) that can be operated via dry contact closure.
CPS3 or CPS3-N4 Option: Enables the addition of a second set of photo-eyes.
Mechanical Reversing Contactor Circuit (M): (115V, 208/230V, 460V, 575V, 24V NEC Class 2 Circuit with 40VA transformer) Industrial linear contactor provides significantly longer control runs than conventional contactors.
Door Lock Sensor: Adjustable door lock sensor can detect if the door lock is engaged and will stop the operator, eliminating jamming and damage to the door or operator.
Drive Reduction: First-stage heavy-duty 5L V-belt; second and third stages #48 chain; #50 drive chain.
Emergency Disconnect: Easy emergency manual operation using an electrically interlocked floor level disconnect and hoist mechanism.
Wiring Type: All operators are factory preset to C2 wiring providing momentary contact to open and stop, with constant contact to close; D1 and E2 wiring are also available. Momentary contact to close (B2 wiring), T, TS, and FSTS wiring can be activated with the use of CPS-RPEN4, CPS-U, CPS-UN4, or CPS-EI safety edge interface. The operator is pre-wired to accept a sensing device, photoelectric sensors, radio controls and most types of access control equipment.
External Radio Control Terminal: Quick, convenient connections for retrofitting or adding radio controls on logic or mechanical operators.
Bearings: Industrial ball bearings on a 1″ output shaft; heavy-duty oil-filled iron bearings on reduction shafts.
Friction Clutch: Adjustable, helps protect against major damage to door and operator should the door meet an obstruction.
Construction: NEMA 1 type electrical box, heavy-duty 11-gauge steel frame with durable powdercoat finish, all reduction sprockets drilled and pinned to shafts.
Push Button Station: 2-button station for OPEN/CLOSE functions is standard with D or D1 wiring. 3-button station is standard with B2 or C2 wiring.
PosiLock® Mechanical Brake System: Self-locking mechanical reduction system that functions as a holding brake.
Warranty: 2-year warranty.
Ancillary Entrapment Protection: (optional) LiftMaster Retro-Reflective Commercial Protector System® photo sensors, 2-wire non-monitored sensing edges and pneumatic sensing edges are considered secondary entrapment protection and may be used to supplement primary entrapment protction or basic constant-pressure-to-close.
2-Position Keylock: (flush mount) Ideal for use with the DJ operator. Provides open/close operation with spring to center (Model 02-109).
