Correct installation of the product is important for safety and performance. If you have not asked 4B to perform the installation of the unit on your behalf, it is critical for the safety of your operation and those who may perform work on your operation that you select a qualified and competent electrical installer to undertake the installation.
• Only use 4B HOTBUS-TN4 temperature nodes for indirect (simulated) testing PRODUCT OVERVIEW 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.
SPECIFICATIONS Supply 1 (Heater Block) Four - AA Batteries (Rechargeable NiMH Recommended) Supply 2 (Display & Heater Relay) Two - 9 Volt Batteries (Rechargeable NiMH Recommended) Direct Testing Mode: 140°F to 190°F (60°C to 90°C) Temperature Control Range Indirect Testing Mode: 77°F to 220°F (25°C to 105°C) Temperature Set Control Adjustable by 10°F or 5°C Increments Display...
Magnified View - Ribbon Cable Connections (Orange) NOTE 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.

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.
