Common faults of electronic universal tester power supply for pipe ring stiffness

Pipe ring stiffnessElectronic universal testing machineCommon power failures
1. The main power supply of the ring stiffness electronic universal tester is not illuminated and cannot move up and down
a. Check whether the power line connected to the test machine is normally connected;
b. Check whether the emergency stop switch is in a screw-up state;
c. Check whether the power supply voltage connected to the test machine is normal;
d. Check whether the safety on the machine socket is blown, please remove the spare fuse and install it.
2. The main power supply of the ring stiffness electronic universal tester is powered but the equipment cannot move up and down.
a. Check whether the device cannot move after 15S (time), because the host needs self-check, which takes about 15S time;
b. Check whether the upper and lower limits are in the right position and have a certain operating space;
c. Check whether the power supply voltage connected to the test machine is normal
d.Whether the emergency stop button is pressed
