Switch (Normally Open): A switch that will close at a specified point (temp, press, etc.). The circle indicates that the component has screw terminals and a wire can be disconnected from it. Switch (Normally Closed): A switch that will open at a specified point (temp, press, etc.).

No circle indicates that the wire cannot be disconnected from the component. Ground (Wired): This indicates that the component is connected to a grounded wire. The grounded wire is fastened to the machine. CONN TO PLATFORM HARNESS (RH-C15) Ground (Case): This indicates that the component does not have a wire connected to ground. It is grounded by being fastened to the machine. CONN TO PLATFORM HARNESS (RH-C13) Reed Switch: A switch whose contacts are controlled by a magnet. A magnet closes the contacts of a normally open reed switch; it opens the contacts of a normally closed reed switch. 422E & 428E Backhoe Loader Electrical System T Sender:

A component that is used with a temperature or pressure gauge. The sender measures the temperature or pressure. Its resistance changes to give an indication to the gauge of the temperature or pressure. NOT USED ON MECHANICAL MACHINE Relay (Magnetic Switch): A relay is an electrical component that is activated by electricity. It has a coil that makes an electromagnet when current flows through it. The electromagnet can open or close the switch part of the relay. Solenoid: A solenoid is an electrical component that is activated by electricity. It has a coil that makes an electromagnet when current flows through it.

The electromagnet can open or close a valve or move a piece of metal that can do work. HBE 1600-UP SNL 2200-UP MAGNETIC LATCH SOLENOID - A magnetic latch solenoid is an electrical component that is activated by electricity and held latched by a permanent magnet. It has two coils (latch and unlatch) that make electromagnet when current flows through them. It also has an internal switch that places the latch coil circuit open at the time the coil latches. CONN TO PLATFORM HARNESS (RH-C12) Machine locations are repeated for components located close together. Harness and Wire Symbols A = Located inside of side console. B = Located on fuse and PRM bracket. 1 2 Deutsch connector:

Typical representation of a Deutsch connector. The plug contains all sockets and the receptacle contains all pins. Sure-Seal connector: Typical representation of a Sure-Seal connector. The plug and receptacle contain both pins and sockets. CONN TO REAR WORK LAMP Harness Identification Letter(s): (A, B, C, ..., AA, AB, AC, ...) CONN TO FRONT WORK LAMP Wire, Cable, or Harness Assembly Identification: Includes Harness Identification Letters and Harness Connector Serialization Codes Harness Connector Serialization Code: The "C" stands for "Connector" and the number indicates which connector in the harness.

KENR8231 July 2007 Harness And Wire Electrical Schematic Symbols Symbols Pressure Symbol Temperature Symbol Level Symbol Flow Symbol Circuit Breaker Symbol T Symbols and Definitions Fuse - A component in an electrical circuit that will open the circuit if too much current flows through it. Switch (Normally Open): A switch that will close at a specified point (temp, press, etc.). The circle indicates that the component has screw terminals and a wire can be disconnected from it. Switch (Normally Closed): A switch that will open at a specified point (temp, press, etc.). No circle indicates that the wire cannot be disconnected from the component. Ground (Wired):

This indicates that the component is connected to a grounded wire. The grounded wire is fastened to the machine. Ground (Case): This indicates that the component does not have a wire connected to ground. It is grounded by being fastened to the machine. Reed Switch: A switch whose contacts are controlled by a magnet. A magnet closes the contacts of a normally open reed switch; it opens the contacts of a normally closed reed switch. 422E & 428E Backhoe Loader Electrical System № At room temperature unless otherwise noted. Sender: A component that is used with a temperature or pressure gauge. The sender measures the temperature or pressure.

Its resistance changes to give an indication to the gauge of the temperature or pressure. T Relay (Magnetic Switch): A relay is an electrical component that is activated by electricity. It has a coil that makes an electromagnet when current flows through it. The electromagnet can open or close the switch part of the relay. HBE 1600-UP SNL 2200-UP Solenoid: A solenoid is an electrical component that is activated by electricity. It has a coil that makes an electromagnet when current flows through it. The electromagnet can open or close a valve or move a piece of metal that can do work.

MAGNETIC LATCH SOLENOID - A magnetic latch solenoid is an electrical component that is activated by electricity and held latched by a permanent magnet. It has two coils (latch and unlatch) that make electromagnet when current flows through them. It also has an internal switch that places the latch coil circuit open at the time the coil latches. Harness and Wire Symbols 1 2 Deutsch connector: Typical representation of a Deutsch connector. The plug contains all sockets and the receptacle contains all pins. Sure-Seal connector: Typical representation of a Sure-Seal connector. The plug and receptacle contain both pins and sockets.

¹ With increasing pressure the closed condition can be maintained up to 2800 kpa (405 psi), with decreasing pressure the closed condition can be maintained down to 170 kpa (25psi). Wire, Cable, or Harness Assembly Identification: Includes Harness Identification Letters and Harness Connector Serialization Codes Harness Connector Serialization Code: The "C" stands for "Connector" and the number indicates which connector in the harness. (C1, C2, C3, .....) Harness Identification Letter(s): (A, B, C, ..., AA, AB, AC, ...) І Contact position at the contacts of the harness connector.
