The ADB Sensor Tester (ADBT) has been designed to test 4B adjustable depth bearing (ADB) style
temperature sensors in the field. During planned maintenance or periodic testing, the ADBT can be
used as a diagnostic tool to verify the alarm and shutdown sequences of the control unit are functioning
as expected. The unit operates in two testing modes, direct (heated) and indirect (simulated).
In direct mode, an integrated heating block within the ADBT heats the ADB sensor probe to the desired
trip point, and allows quick and easy real life testing of the sensor and temperature monitoring system.
Using indirect mode allows simulated testing of NTC type sensors within the network of 4B’s T500
Hotbus control unit. By connecting the ADBT to a TN4 node, testing of the node and the network is
accomplished by simulating the temperature above the sensor’s trip point and monitoring the response
of the control unit.
• Do NOT use when hazardous dust is present
• Only use ADB Tester with 4B ADB bearing temperature sensors for direct (heated) testing
• Only use 4B HOTBUS-TN4 temperature nodes for indirect (simulated) testing

The ADB tester uses four AA and two 9-volt batteries (not included). In order to get the longest use,
rechargeable NiMH batteries are recommended. Alkaline batteries can also be used.
To access the AA battery compartment on the bottom of the unit, remove the two central screws holding
it in place. First, insert the four AA batteries (Image A). Be sure to match up the + and – indications
on the batteries with the + and – indications on the battery compartment. Then replace the battery
compartment lid and the two screws.
To access the 9-volt battery compartment inside the unit, remove the six other screws that hold the case
together. Once removed the case will split into two halves, carefully unplug the ribbon cable (Image
C) and then insert the two 9-volt batteries (Image B). Be sure to match the + and – indications on the
batteries with the + and - indications on the battery compartment. To reassemble the unit, carefully re-
connect the ribbon cable (Image C), and then bring the two halves back together (be careful not to trap
any cables between the screw holes on the two halves). Replace the six screws to secure the unit.
NOTE: Do not use an old battery with a new one, or mix different types of batteries together.

Batteries are not included with the ADBT. 4B recommends using rechargeable NiMH batteries.
The ADBT must be powered by batteries to perform direct (heated) testing. However, indirect
(simulated) testing does not require batteries as power will be drawn from the node.

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
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.
The temperature simulation control knob and output cable are not used during direct testing mode.

INDIRECT TESTING MODE -
Indirect mode simulates temperatures of NTC type sensors within the network of 4B’s T500 Hotbus
control unit. To test, connect the supplied output cable into the “Simulation Mode Output” plug on the
top of the ADBT (Image F). Then connect the three way female plug (Image G) into a TN4 input node
by first disconnecting the existing NTC sensor connection. Since the ADBT will be drawing power from
the node, battery power is not required for indirect mode testing. Once all connections have been made
(Image H), the user can now rotate the black temperature simulation control knob on the top of the
ADBT to simulate the following conditions:
1. NTC Sensor Open Circuit (No Sensor Installed / Plugged In)
2. NTC Sensor Temperature Range 77°F to 220°F (25°C to 105°C)
3. NTC Sensor Short Circuit (Sensor Wiring Issue)
To test for an open circuit, with the front of the ADBT facing toward you, turn the knob all the way
counter clockwise until it clicks (Image I). For temperature range testing, start in the open circuit position
and then slowly turn the knob clockwise until you hear a “click”. The “click” sets the temperature to a
simulated 77°F (25°C), as you continue to turn the knob clockwise the simulated temperature increases
until it reaches 220°F (105°C). To test for a short circuit, turn the knob completely clockwise.
After successful direct testing, ensure that the ADB Sensor is re-installed into the bearing housing as
outlined in the ADB Sensor installation instructions.
After successful indirect testing, ensure that the NTC sensor connection is re-installed on the TN4
node as outlined in the node/system installation instructions.
The LED display and the Set “+ / - “ buttons are not used during indirect testing mode.
