Danfoss Cables and Followers Installation guide

Cables and Followers

BLN-95-8975-4 Issued: May 1996

DESCRIPTION

The Cables and Followers described in this instruction literature are designed for use with Danfoss controllers and sensors such as the R7232A Proportional Indicating Controller, SB104A Microsyn Rotary Position Sensor W895A Proportional Grade/Steering Controller, MCW100A,B Time Proportional Rotary Position Controller, MCW100C,E Time Proportional Rotary Position Controller and MCW102B Proportional Rotary Position Controller. Followers are used to run along a stringline for grade or steering applications or along a hard reference surface to match the existing grade. Cables are provided to make electrical connections between components of the control system and come in a variety of lengths and connector types.

FEATURES

• Number of followers meets almost any grade application

• Right-angle followers give way when they strike a fixed object, preventing follower damage. See Figure 3.

• Environmentally sealed cables and connectors resist moisture.

• No tools required to fasten—only turning one thumbscrew is necessary

• Cables simplify installation of control components, making wiring easy

INSTALLATION

STEERING FOLLOWERS

The Steering Wand is pictured in the Ordering Information KG07002 photograph. The device attaches to either the left or right hub of a steering controller, such as the SB104A or W895A. When the system is steering on course, the shaft of the Wand will be vertical.

RIGHT ANGLE GRADE FOLLOWERS

The grade followers shown in the Ordering Information KG04003 and KG04004 photographs are used to follow a grade stringline. The two followers are identical, except that one has a longer contact tube. They may be used on either side of the controller in any of four orientations: 45 degrees downtrailing, 45 degrees down preceding, level trailing or level preceding.

SKATE AND SKI ASSEMBLIES

The Skate assembly, shown in Ordering Information KG06001 photograph, attaches to the Grid Arm by slipping the Skate’s pin through the retaining hole in the Grid Arm (in place of the tube) and fastening it with the retaining pin.

The Skate assembly always trails the controller at 45 degrees, following over a hard, pre-formed surface.

The Ski runner, shown in Ordering Information KG02001 photograph, snaps into the Skate assembly to follow a rigid surface. As with the Ski assembly alone, it always trails the controller at 45 degrees down.

CABLES

Cables and connectors are sealed against moisture when mated with Danfoss devices: the connector insert faces are rubber, so that a face-to-face moisture seal is made. The cable termination into the connector is likewise moisture sealed.
