v x3 is the threshold for rear path and rollers closed v x4 is the threshold for rear path and rollers open v x1, x2, x3, x4 are numbers in hexadecimal format, which correspond to the measured voltages, resolution of 20 mV. Press any key to go to step 8. 8. The following displays: T&D21 Sensor Test SENSOR LEVEL ? YES ... NO This part of the test is intended for use by Product Engineering, and allows the user to examine sensor output voltages. 9. Press the Start key to skip to step 10 on page 227. Press the Line Feed key to enter. The current sensor measurements display: T&D21 Sensor Test C:x1 F:x2 R:x3 PRESS A KEY where: v x1 is manual path measurement v x2 is front path measurement v x3 is rear path measurement v x1, x2, x3 are numbers in hexadecimal format, which correspond to the measured voltages, resolution of 20 mV. The display continuously updates to track sensor output changes. Press any key to go to step 10 on page 227. Chapter 2. Diagnostics 226
