  1. ALS Hardware Safety Interlocks • The ALS Hardware safety interlocks is designed to disable power to all actuators in case of hardware or software failure, with any of the following conditions: • Net rotational force (= Sum of link forces), shall be within +/- 100Kg • Sum of 4 load bearing link forces, when compared against a gravity sensor, shall be within +/- 100Kg • Each of the 4 load bearing link forces, when compared against gravity sensor, shall be within +/- 100 Kg; this might have operational implications when moving the telescope through large elevation angles. • Each non-load bearing link force, shall be within +/- 100Kg • Watchdog timers will shut down system when software has lost communication for more than 1 second • Any ALS system power supply is out of range • External SOAR Panic Button is pressed
