TESTER OPERATION

ADB bearing temperature sensors are designed to report real-time bearing temperatures to a control

unit (PLC, 4B Hazard Monitor, etc.). The control unit should be able to alarm and shut down machinery

when a hazardous operating temperature has been detected by any ADB sensor.

The ADB Sensor Tester verifies that the ADB sensor is functioning properly, and that the control unit

and associated wiring are operating correctly. During planned maintenance or periodic testing, the

ADB Sensor Tester can be used as a diagnostic tool to verify the alarm and shutdown sequences of the

control unit are functioning as expected. The ADBT functions in two testing modes:

DIRECT TESTING MODE -

The LED display of the ADBT shows the actual heater block temperature in degrees Fahrenheit or

Celsius. When the ADBT is turned on it will display the last selected temperature units on the LED

display, users can select the required temperature units within two seconds after powering up the ADBT.

To select °C press the "+" button, or press the "-" button to select °F (Image D). If no button is pressed

within two seconds after powering up, the ADBT will default to the previously selected temperature

setting.

Direct mode uses the integrated heating block within the ADBT to heat the ADB probe. To test, remove

the ADB bearing sensor probe from the housing and insert it into the ADB probe input (Image E). The

heater block target temperature should be set above the control units alarm operating temperature. To

set the target temperature press the "+" or "-" buttons to increase or decrease the target temperature

by 10°F or 5°C increments. The LED display will flash between the target temperature and the heating

blocks current state (heating or cooling). When the target temperature is reached, the display will stop

flashing and show the target temperature.

When the heater block reaches the alarm temperature, the ADB sensor will relay this data to the control

unit, allowing you to verify that the alarm and shutdown sequences run as expected.
