and if the output voltage of the potentiometer does not exceed the standard output voltage range, the potentiometer has no fault.
Further comprising:
and if the potentiometer fails, adjusting the offset of the potentiometer, and comparing the adjusted output voltage of the potentiometer with the standard output voltage range again until the output voltage of the potentiometer is within the standard output voltage range.
The adjusting the offset of the potentiometer specifically comprises:
loosening a fixing screw of the potentiometer through a spanner;
and adjusting the offset of the potentiometer through the potentiometer adjusting tool.
Specifically, the power supply shown is a 12V dc programmable power supply 6.
Specifically, as shown in fig. 2, it is a schematic structural diagram of a potentiometer, the potentiometer is provided with three connection points, which are a first connection piece 8, a second connection piece 9 and a third connection piece 10, respectively, and an arc-shaped resistor 11 is arranged between the first connection piece 8 and the third connection piece 10, wherein the first connection piece 8 and the third connection piece 10 are connected to the positive pole and the negative pole of the 12V dc program-controlled power supply 6, respectively, the positive and negative connection wires of the multimeter are connected to the first connection piece 8 and the second connection piece 9, respectively, and the second connection piece 9 is connected to the movable dial 12, so that the multimeter measures the output voltage of the resistor 11 between the first connection piece 8 and the movable dial 12, and rotates the rotating shaft 13, the contact point of the movable dial 12 and the resistor 11 changes, and the effective resistance of the resistor 11 between the first connection piece 8 and the movable dial 12 also changes, correspondingly, the output voltage of the resistor 11 between the first connecting piece 8 and the movable paddle 12 also changes. The rotating shaft 13 is associated with a main handle of the driver controller, the main handle rotates to generate cam action, the cam drives a large gear to act, the large gear drives a small gear on the potentiometer to act, the small gear drives the rotating shaft 13 to rotate after acting, the rotating angle of the rotating shaft 13 determines resistance change on the potentiometer, and finally voltage output change is achieved. When the potentiometer is shifted, a gap is formed between the large gear and the small gear, when the main handle drives the large gear to rotate, the gap is formed between the small gear and the large gear, the rotation angle of the small gear is insufficient, and finally the output voltage value is abnormal, so that the output voltage of the potentiometer needs to be detected and compared with the normal voltage to judge whether the gap between the small gear and the large gear influences the normal output voltage value, and the offset of the potentiometer is adjusted through the potentiometer adjusting tool.
Specifically, as shown in fig. 1, it is a potentiometer overhaul measurement circuit diagram. The second resistor 2 and the third resistor 3 are variable resistors, the resistance value of which is in the range of 0-500 omega, a first resistor 1 and a fourth resistor 4 are respectively connected in series between the positive electrode contact point of the second resistor 2 and the third resistor 3 and the 12V direct current program-controlled power supply 6, the resistance values of the first resistor 1 and the fourth resistor 4 are 55 omega, the second resistor 2 and the third resistor 3 are equivalent to a potentiometer PT1 and a potentiometer PT2, the contact points S1 and S4 correspond to the first connecting piece 8, the contact points S2 and S5 correspond to the second connecting piece 9, the contact points S3 and S6 correspond to the third connecting piece 10, a first universal meter 5 is connected in parallel between contact points S2 and S3, a second universal meter 6 is connected in parallel between contact points S5 and S6, the contact points S1 and S4 are connected in parallel and then connected with the positive pole of the 12V direct current programmable power supply 6, and the contact points S3 and S6 are connected in parallel and then connected with the negative pole of the 12V direct current programmable power supply 6.
Specifically, as shown in fig. 3, it is a schematic diagram of the measurement result of the potentiometer.
The driver has 13 total levels, for example, the standard output voltage range of the potentiometer of EB level is 0.18-0.58V, the output voltage of the potentiometer PT1 is 0.28V, the output voltage of the potentiometer PT2 is 0.29V, and the output voltages of the potentiometer PT1 and the potentiometer PT2 are both in the standard output voltage range, that is, the potentiometer PT1 and the potentiometer PT2 work normally under EB level; the standard output voltage range of the B7 level potentiometer is 0.10-1.50V, the output voltage of the potentiometer PT1 is 1.26V, the output voltage of the potentiometer PT2 is 1.28V, and the output voltages of the potentiometer PT1 and the potentiometer PT2 are both in the standard output voltage range, namely the potentiometer PT1 and the potentiometer PT2 in the B7 level normally work; the standard output voltage range of the B6 level potentiometer is 0.10-1.50V, the output voltage of the potentiometer PT1 is 1.26V, the output voltage of the potentiometer PT2 is 1.28V, and the output voltages of the potentiometer PT1 and the potentiometer PT2 are both in the standard output voltage range, namely the potentiometer PT1 and the potentiometer PT2 in the B6 level normally work, and similarly, the potentiometer PT1 and the potentiometer PT2 in the B1-B5 level, the OFF level and the P1 level normally work; the standard output voltage range of the potentiometer at the stage P2 is 7.73-8.13V, the output voltage of the potentiometer PT1 is 7.86V, and the output voltage of the potentiometer PT2 is 7.72V, so that the output voltage of the potentiometer PT1 is in the standard output voltage range, the output voltage of the potentiometer PT2 exceeds the standard output voltage range, the potentiometer PT2 has faults at the stage P2, and similarly, the potentiometer PT2 has faults at the stages P3 and P4. When other stages work, the output voltages of the potentiometer PT1 and the potentiometer PT2 are in a standard output voltage range, and after the output voltage of the potentiometer PT2 and the output voltage of the potentiometer PT2 are checked to be normal independently, the reason that the output voltage of the potentiometer PT2 exceeds the standard output voltage range is judged to be that the fixed position of the potentiometer PT2 generates deviation, and the angle of the rotating shaft 13 driven by the main handle of the driver controller is further influenced.
The driver controller is provided with a travel switch.
Further comprising:
closing the travel switch, and measuring the contact resistance of the travel switch through a low resistance tester;
and comparing the resistance value of the contact resistor of the travel switch with the resistance value of the standard contact resistor.
The resistance value of the standard contact resistor is 1-100m omega.
Specifically, the resistance value of the travel switch during closing is measured through the low resistance tester and compared with the resistance value range of the standard contact resistance of 0-100m omega, whether the travel switch is short-circuited or has other faults is further judged, and if the measured resistance value exceeds the resistance value range of the standard contact resistance, the travel switch is replaced.
