7.3 SETTING GRIP PROTECTION Grip protect is an L2 software feature. This allows you to set a maximum load that protects you from accidently overloading your testing fixture. With the grip protection feature, you specify a maximum load. If this load is achieved during a test, the test will abort and the crosshead will stop. NOTE Use the Grip Protection feature within your L2 Controller and software to protect your test fixture for inadvertent overloading.
7.4 LOAD CELL PROTECTION Your FLC load cell sensors have mechanical overload protection. The Economy and Sealed Series sensors have mechanical overload protection up to 150% of the sensor's rated capacity. The Premium Series have protection up to 1000% of the sensor's rated capacity. The L2 Controller's load bar graph and sensor symbol (on the header) will display a color to depict the amount of load being measured by the sensor relative to the sensor's rated capacity. When the color YELLOW is being displayed, you should use caution.When the color RED is being displayed, you should use extreme caution and be prepared to stop your test. When your sensor is measuring between 0 and 74% of its rated capacity, the bar graph will display GREEN. When your sensor is measuring between 75% and 90% of its rated capacity, the bar graph and sensor symbol will display YELLOW. When your sensor is measuring above 75% of its rated capacity, the bar graph and the sensor symbol will display RED. IMPORTANT • Observe the load bar graph indicator and sensor symbol when performing a test. If the bar graph and sensor symbol display RED, be prepared to stop the test to protect your load cell sensor from an overload condition. • Your L2 software also contains load protection for your load cell sensor. Within the L2 software, all Quick Test setups and your Tension and Compression stages, contain CONDITIONAL SETTINGS. Included in these settings is the ability to stop the crosshead when a load limit is reached. It is recommended that you use the Load Condition.
Use to assign a "sign" to either tension or compression. Normally, compression is a negative number.
The Grip Load is used to protect your gripping fixture from damage due to overloading. Set the Grip Load to a load capacity that is less than the capacity of the gripping fixture. If this load is achieved, the crosshead will stop and the test will abort.
Use to assign a particular FLC load cell sensor to the frame or to a test setup. Use the touch target to sequence through all of the available FLC load sensors.
When the L2 Controller is connected to the FMS Frame via the USB cable, the software automatically recognizes the frame and the frame's maximum load capacity.
Crosshead status arrows animate when the crosshead is moving and shows the direction of travel.
Shows the test mode (Tension) and the direction of crosshead travel.
The Load (L) and Distance (D) targets. Press to zero the measured value being displayed.
