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.

The LED display and the Set "+ / - " buttons are not used during indirect testing mode.

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.
