Mode Signal Measurement point Measuring equipment Adjustment page Adjustment address Specification value D 0E, 0F, 10, 11, 12 YYh = D8h ± 06h Power ON Any Displayed data on adj. remote commander
Connection: Referring to Fig. 2-2, connect the following equipment. (1) Connect the regulated power supply and a digital voltmeter to the battery terminal. (2) Connect the adjusting remote commander to the CN902 on YM-11 (G)/(H) board. Adjustment Procedure: (1) Adjust the output voltage of regulated power supply so that the battery terminal voltage is 7.2 Vdc. (2) Turn ON the POWER switch on the set. (3) Set data: 01 to page: 1, address: 00. (4) Set data: 01 to page: 2, address: 00. (5) Set data: 01 to page: 2, address: 2C. (6) Adjust the output voltage of regulated power supply so that the battery terminal voltage is 8.3 ± 0.02 Vdc. (7) Read data (YYh) on page: 2, address: 2D. (8) Confirm that the data (YYh) satisfies the specification value. (9) Using the following formulas (calculation of hexadecimal numbers), calculate the adjustment data and enter them to respective adjustment addresses. Address: 0E D0E = YYh + 04h Address: 0F D0F = YYh Address: 10 D10 = YYh � 5Ah Address: 11 D11 = YYh � 55h Address: 12 D12 = YYh + 09h
Note: After setting each data, be sure to press the PAUSE button on the adjusting remote commander.
(10) Set data: 00 to page: 1, address: 00. (11) Set data: 00 to page: 2, address: 00. (12) Set data: 00 to page: 2, address: 2C.
