CHAPTER 20 SENSORS AND MOTORS

SENSORS This section gives details of the various sensors used in the machine. All

sensors used on the machine fall within two categories, these are:

• Conventional Switch Sensors

• Solid State Switch Sensors

Conventional

Switches

The machine uses the following types of conventional switch sensors:

• Reed Switch

• Safety Switch

•Microswitch

• Pressure Switch

In all cases to initiate a logic 1 (on state) at the input, the sensor must connect

the signal input to 0V.

Figure 20-1 Typical Conventional Switch Schematic

Testing 1. Activate the sensor according to type and measure the voltage at the output

terminal with respect to 0V. The sensor signal output should change

between approximately 0V and 12V.

2. Remove switch from the circuit and measure continuity.

In all cases check digital inputs under diagnostics at the MMI.

NOTE

Full listing of digital inputs are listed in the Diagnostics Chapter of the User

manual.

Solid State

Switches

The machine uses the following types of solid state sensor switches:

• Hall Effect Sensors

• Opto Sensors

• Capacitive Proximity Sensor

In all cases to initiate a logic 1 (on state) at the input, the sensor must connect

the signal input to 0V.

Figure 20-2 Typical Solid State Schematic

Testing Solid state sensors can only be tested in circuit as they require a logic supply

voltage.

1. Check for the 12V logic supply to the sensor.

2. Activate the sensor according to type and measure the voltage at the output

terminal with respect to 0V. The sensor output signal should change

between approximately 0V and 12V (see individual sensor descriptions for

more details).

NOTE

Full listing of digital inputs are listed in the Diagnostics chapter of the User

manual.

Sensor Location Sensor locations are detailed in the Sensor Table of this chapter. Machine

location for individual sensors are detailed in the respective module chapter

overview sections, ie Solvent Low Sensor - can be found in the Under Screen

Cleaner chapter (Sensors section).
