Shop Norton 5700 Series Automatic Door Parts for the Norton LEO® low energy power operator. Automatic Door and Hardware supplies replacement components for maintaining and repairing Norton 5700 Series automatic swing door operators used on commercial ADA-accessible openings.
The Norton 5700 Series combines an automatic power operator with the proven Norton 1601 / 1601BF Series mechanical door closer. Its design uses an inverter, motor and mechanical closer to provide powered automatic opening while retaining the controlled closing characteristics of a commercial hydraulic door closer.
Whether you are servicing the operator electronics, motor and drive system, mechanical closer, arm assembly or operator cover, use the diagrams and part descriptions on this page to help identify the correct Norton 5700 replacement part for your automatic door.
The 5700 Series contains both electronic and mechanical components. Common service components identified within the Norton 5700 operator include:
The Norton 5700 LEO operator contains a number of individual service components. Depending on the model and installation, replacement components may include:
The Norton 5700 Series is available in different configurations depending on which side of the door the automatic operator is mounted.
The Norton 5710 configuration is designed for hinge-side / pull-side mounting and uses a rigid arm and slide-track arrangement.
When ordering 5710 replacement parts, verify that the arm, track and related components correspond with your existing pull-side installation.
The Norton 5730 configuration is designed for stop-side / push-side mounting and uses a standard-duty double-lever arm arrangement.
Verify the existing operator model and mounting configuration before ordering replacement arm components.
Norton identifies several individual arm and track components for the 5700 Series. Always compare the existing operator configuration and part number before ordering.

The Norton parts documentation identifies the 5700COV operator cover. Verify your existing operator model, finish and application before ordering replacement cosmetic or enclosure components.
Understanding how the 5700 operates can make troubleshooting and replacement-part identification easier.
During automatic operation, the integrated motor and drive system powers the door open. During the normal closing cycle, however, the Norton 1601 mechanical door closer provides the spring force and hydraulic control that closes the door.
This design means that when the door is manually opened, there is little resistance from the powered drive system. It also allows the door to continue functioning as a mechanical door closer if electrical power is turned off.
The mechanical closer is an important component of the Norton 5700 operator system.
Depending on the operator configuration, the 5700 Series uses a Norton 1601 or 1601BF Series closer with hydraulic and spring adjustments that may include:
The 5700 operator includes electronic controls for powered opening and adjustment. The operator's controls provide adjustments and functions associated with:
The operator also incorporates an activation-switch terminal, relay terminal and circuit-breaker arrangement. Correct diagnosis is important before replacing electronic components, since an activation device, locking device, wiring issue or adjustment may sometimes produce symptoms that appear to be an operator component failure.
The Norton 5700 Series can be activated using compatible automatic door activation equipment. Depending on the installation, activation options can include:
Activation switches and sensors are application-dependent and may be ordered separately from the automatic door operator.
The Norton 5700 can also interface with compatible electric locking hardware. When the automatic door is activated, the operator's relay can be used as part of a properly designed system to coordinate release of compatible electric locking hardware before powered opening begins.
The operator provides an adjustable motor-start delay that can provide locking hardware time to release before the motor begins opening the door.
