During Active Maintenance, the voltage on the OD should decrease as the speed of the truck increases. With the truck at rest, the reading should remain steady and not fluctuate by more than 0.2V. The test is a success if the voltage displayed is within these limits: Test Setup This test displays the voltage produced by the TM based on input from JPS14-9 (Q1-C Sense). Diagnosis and Repair Test A10 – Display Q1-C Sense Voltage The Power Card’s current limit threshold is preset at the factory and is not adjustable. It is normal for the Power Card to go into current limit, particularly when accelerating. If it must be operated near power-lines, safe clearance limit must be maintained. The equipment must not be operated near power-lines. If these results are not observed, the test has failed. Below are 11 Essential Cherry Picker Safety Tips, follow the link to see all of them and do well to implement them for your safety. The voltage should increase 1V per 100A through the armature of the traction motor. During deceleration (REGEN), the voltage should decrease.During acceleration, the voltage should increase.The reading should remain steady, and should not fluctuate by more than 0.02V. The value displayed should be within 5.7 and 6.3V with the lift truck at rest. From wheels and tires to shop supplies and battery room equipment, our extensive catalog includes our own durable, precision-engineered. The Operator’s Display (OD) displays the voltage the TM reads from the current sensor. To help keep your trucks, equipment, and business running, Raymond offers a comprehensive range of top-quality partsin stock and available for rapid delivery from a location near you. This test can also be run from Active Maintenance. The Power Card’s current limit threshold is preset at the factory and is not adjustable.įor information on using Maintenance Mode, refer to page 3-19. The current sensor continuously monitors the current flowing through the drive motor adjusts its performance accordingly. This test displays the voltage the Tractor Manager (TM) reads from the current sensor (CT) on the Power Card (at JS3-4). Test A10 – Display Q1-C Sense Voltage (-124) If cycling the key switch OFF/ON does not clear this fault code, then follow the procedure below. Possible CausesĬode 23 – Open Detected In Main Transistor Circuitĭuring SelfTest, proper current levels were not sensed by CT1 (on the Power Card) from the Power Transistor (Q1). After replacement, there are additional tests that need to be ran to determine the cause of the Q1 failure. It is almost guaranteed that the Q1 transistor must be replaced. Error code 23 on a Raymond order or a Caterpillar order picker can be a tough code to solve.
