True Safety for both the Operator and the Machine
02 True Safety for both the Operator and the Machine
Protects Operators from Debris
Highly transparent, impact-resistant polycarbonate safety covers are provided as standard for the front and rear of the test space. This prevents samples from flying out when they break. An interlock function is provided, so that if the safety cover is not closed, testing and the return operation are prevented, reducing the risk of accidents.
• Using optional accessories, all movement including the jog operation can be prohibited.
Prevents Jig Impacts
The intelligent crosshead always recognizes its current position. If the jigs get too close due to an operational error, an impact warning is issued, and the crosshead is stopped automatically.
Contact Detection and Instantaneous Emergency Stop
The machine status is diligently monitored even when the crosshead is moved with the safety cover open, such as when adjusting the position of test jigs or attaching samples. If the machine detects the test force changes due to contact with jigs or hands, the crosshead performs an emergency stop.
Overload Detection Function
If the machine detects a test force exceeding the load cell capacity, the crosshead stops automatically. This reduces the risk of load cell damage from overloads during the jog operation and during testing. (Note that the possibility of damage cannot be completely eliminated.)
Stroke Limit Switch
Pinch, Position, and Release Grips
A stroke limit switch, which sets the limits of crosshead movement, prevents crosshead and jig impacts. A spring mechanism within the switch reliably sets the position when the hand is released, preventing configuration errors due to procedural mistakes such as insufficient tightening.
Self Check Function
Machine’s Self-Diagnostic Function
The function constantly monitors sensor amplifler calibration information, the operational status of the testing machine, the power supply voltage, and the communications status. The user is immediately notifled when a problem occurs. Additionally, the usage time and number of uses of the machine are checked, and a notification is issued when prescribed values are reached. This assists with the assessment of maintenance periods and helps reduce downtime. (It does not detect offsets in measurement values from load cells and extensometers due to age-related changes. Periodic maintenance and inspections by a field engineer are recommended.)
