The GESTER Mattress Spring Fatigue Tester may encounter some abnormal situations during use. Correctly identifying problems and taking appropriate measures to resolve them will help maintain the stable operation of the Mattress Spring Fatigue Tester and extend its service life. This article will discuss abnormal problem handling to ensure the safe and efficient operation of the equipment.
What is the Mattress Spring Fatigue Tester
Mattress Spring Fatigue Tester/ Cornell Tester is applied to test the endurance capacity under the long-term repetitive load and the compression deformation for the mattress. Accord with the standard ASTM F 1566.
With sofa Cornell fatigue life test method, motor drive eccentric wheel, adjust the impacting height of the impact block, then impact the testing mattress by 120-160 times / min, counter measures the impacting times, shut down automatically when reaches the setting times.
Handling of Abnormal Issues
Fault 1: The machine cannot be turned on.
Reason: The fuse is blown.
Solution: Check and replace the fuse with a new one.
Fault 2: The impact pad cannot return to the highest or lowest point.

Solution: Check if the position and distance of thesensor are too far to
trigger properly. If the position is appropriate but does not trigger, or if
the light stays on, a new sensor needs to be replaced.
Fault 3: The impact pad cannot move.
Reason: Servo motor malfunction.
Solution: Check the status of the servo drive and solve the problem based on the fault code on the drive.
Fault 4: HMI screen cannot communicate with PLC.
Reason: Communication cable failure between HMI screen and PLC.
Solution: Check and reinstall the communication cable.
Fault 5: The software shows that it cannot connect to the machine.
Reason: Communication cable malfunction between motherboard and computer.
Solution: Check and reinstall communication cables and connectors.
