The digital sensor information for each is displayed on a separate screen. Refer to Illustration 4. Refer to Table 2 for an explanation of related parameters for the digital sensor.
| Configuration and Status Information for the Digital Sensor | |
|---|---|
| Digital Sensor | Description |
| Digital Sensor Input #1, 2, 3, 4 Type Configuration | Configuration Type parameter defines whether a sensor is attached. If attached, the state of the switch contacts under normal operating conditions (Normally Open or Normally Closed). |
| Digital Sensor Input #1, 2, 3, 4 Monitoring Condition | Defines the monitoring condition for the digital input. If the digital input is in the alarm state (opposite the normal state), an event is recorded and sent to the VisionLink application. Alarm state is as specified in digital sensor input type configuration. delay time is specified in digital sensor input delay time, while the digital input monitoring condition is true. |
| Digital Sensor Input #1, 2, 3, 4 Description | The digital sensor input description parameter is a 24 character field used to describe what the sensor is monitoring. This value is used in the office software to display the sensor status. |
| Digital Sensor Input #1, 2, 3, 4 Delay Time | Defines the delay time before an alarm condition is recorded. If the digital input is in the alarm state (opposite the normal state), an event is recorded and sent to the VisionLink application. Alarm state is as specified in digital sensor input type configuration. Delay time is specified in digital sensor input delay time, while the digital input monitoring condition is true. Set this time correctly so spurious alarms are not set or alarms are missed. |

Machine Security (Available in China Only)
Derate - Some machines can have the machine engine derated remotely by the owner of the machine. The action causes the machine to operate much slower than normal. A warning is given before this action occurs on the display with the machine lock icon and "security pending". When engine derate has happened, the machine display shows the machine lock icon and "Security Enabled". The operator should move the machine to a safe location, apply the parking brake, power the machine down, notify the site supervisor, and your Cat dealer.
Disable - Some machines can be prevented from starting remotely by the owner of the machine. When disabling has happened, the machine display shows the machine lock icon and "security enabled". The operator should notify the site supervisor.
Tampering - Tampering with the Product Link can also result in engine "derating"or "disabling" of the machine. To avoid "derating"or "disabling", prevent tampering with the Product Link. If, machine diagnostics occur due to Product Link notify your site supervisor immediately to prevent derating or disabling. An example of this situation is an antenna becoming damaged.
Note: The appropriate Monitor, Engine and Product Link software must be flashed to enable this functionality. Not all machines support this function. Contact your Technical Service Representative for additional details.
