6.4 SYSTEM STARTUP Prior to starting your FMM force measurement system, ensure that you understand the operating and safety features of your system. Also, always verify operating controls prior to use. • Ensure that all cables are properly installed and securely connected. • Turn power to the FMM frame and L1 tablet to the ON position. • Allows your system to warm-up by allowing the system to stabilize after a 15 minute warm=up period. • Launch the L1 tablet software. • Create and perform your force measurement testing with exceptional ease and accuracy. • Contact your Starrett Representative for assistance if needed. 6.5 SETTING CROSSHEAD TRAVEL LIMITS Your FMM frame has two crosshead travel limits located on the center bar of the column. These limit switches are intended to protect the crosshead from traveling too far in either direction. NOTE Always set the crosshead travel limits at the desired location before starting a test. Failure to set these crosshead limits may result in injury due to unexpected crosshead motion and damage to your load cell sensor and testing fixture. Set the upper and lower crosshead travel limits after you have established the crosshead starting position for your test, but before you being testing. Each travel limit operates as an adjustable block. Each limit has a thumbscrew that you tighten and release by hand. Loosen the thumbscrew so that the limit moves freely up or down on the column. Slide the limit up/down on the column to the desired position. Both limits should be positioned just beyond the normal travel distances for your test. When the crosshead reaches the maximum pre-set travel, the limit switch actuator contacts one of these stops. This causes the crosshead to stop its motion. NOTE Your L1 software also contains travel protection for your crosshead. These should be used in addition to your mechanical crosshead travel limits. Within the L1 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 distance limit is reached. Should the crosshead contact either the upper or lower travel limit, the test will stop and the crosshead will stop moving. If this happens, use the jog switch on the your FMM frame base to move the crosshead off the limit stop. Press the DOWN direction on the jog switch to move the crosshead off the upper limit. Press the UP direction on the jog switch to move the crosshead off the lower limit. The crosshead motion arrows on your L1 tablet will display and animate when the crosshead is in motion.
