How to check the open circuit in the electric pallet jack?

As we all know, the circuit system is very important for the electric pallet jack. However, some minor faults are unavoidable. Common circuit faults include open circuit, short circuit and poor contact. Previously, we said how to judge whether there is a short circuit in the electric pallet jack. Today, the manufacturer which has forklift for sale will tell you how to check whether there is an open circuit in the electric pallet jack.

There are two ways to check whether the circuit of the electric pallet jack is faulty. The first method is lamp test. We need to make a test lamp with the instrument bulb. During the inspection, clamp the fishtail clamp at the reliable place of the grounding, turn on the switch, and then test the test rod head from the positive pole of the battery to the direction of the electrical equipment section by section according to the wiring sequence. The manufacturer which has forklift for sale told everyone that if the test light is on, the circuit between the battery and the ammeter is normal. If it is not on, the circuit is open. The open circuit is in the circuit between the test lamp on and the test lamp off.

The second method to check whether the electric pallet jack is faulty is the instrument inspection method. We need to use a DC voltmeter or multimeter, adjust it to the 20V gear, use a black test rod to ground, and the red test rod starts from the positive pole of the battery, and contact the electrical equipment in the direction of the wiring sequence in order to check the voltage. If the pointer of the voltmeter can swing and display voltage, the circuit is normal. If the pointer of the voltmeter cannot swing, it indicates that there is an open circuit. The open circuit occurs in the circuit between the indication and no indication of the voltmeter pointer. The manufacturer which has forklift for sale reminds that if the voltage indication value is too small, there is a poor contact in the circuit.

This is the way to check whether there is an open circuit in the electric pallet jack. The electric pallet jack is a kind of logistics storage equipment that relies on electric power to walk and lift, so the circuit system is very important for it. The poor operation of the circuit system will affect the working efficiency of the whole forklift. When the open circuit problem occurs, you can use the method taught by the manufacturer who sells the forklift to check, repair or replace it in time. If you are not familiar with the structure of the electric pallet jack, it is recommended to contact the maintenance personnel directly or contact the manufacturer which has forklift for sale for solution.
