Cause: The energy storage motor fails to store energy, preventing the circuit breaker from closing automatically. Analysis and Handling: If the energy storage indicator light is off before closing, check the control power supply of the energy storage motor.
[pdf] A faulty Y1 solenoid or improperly actuated S2 microswitch can interrupt the closing circuit. Measure Y1 coil resistance. If abnormal (shorted or open), replace the Y1 module. If resistance is normal, check S2 actuation.
[pdf] The first accumulators for 's hydraulic dock machinery were simple raised . Water was pumped to a tank at the top of these towers by steam pumps. When dock machinery required hydraulic power, the of the water's height above ground provided the necessary pressure. These simple accumulators were extremely tall. For instance, , b. Advantage: Virtually no nitrogen escapes so they will not have to be recharged. Disadvantage: A bit heavier, and less efficient than the bladder model.
