Attempt to arm the Astrella by arming local room interlock module on the Astrella enclosure before arming the room module. Astrella does not arm. #. With Hutch-1 unarmed, arm the room interlock module on the Astrella enclosure. #. The room interlock module only lights the LED for :orange:`ROOM ARMED`. #. The local interlock module only lights the LED for :green:`LOCAL CONTACT DISARMED`. #. The laser warning control module shows :red:`LASER ON`. #. Laser E-stops buttons should be on. - Outside enclosure south - Outside enclosure west - Experimental Chamber - Inside enclosure south - Inside enclosure east - Inside enclosure west #. Arm the local room interlock module on the Astrella enclosure. The local interlock module only lights the LED for :green:`LOCAL CONTACTS ARMED`. #. VIEWMARQ in Hutch-1 Control displays :green:`LASER SAFE - ASTRELLA ARMED`. #. Beacon stacks show green and white LEDs on. - Hutch-1 Control - Astrella LASER ENCLOSURE INTERLOCK protocase #. Go through all Astrella enclosure curtain doors and open them one at a time.

Rearm Hutch-1 as a laser lab and rearm the Astrella. All laser warning modules display :red:`DANGER LASER ON`. #. VIEWMARQ in Hutch-1 Control displays :red:`DANGER LASER HAZARD - ASTRELLA ARMED`. #. Beacon stacks show white LED on. - Hutch-1 Control - Astrella LASER ENCLOSURE INTERLOCK protocase .. figure:: /images/user_docs/Hutch-1_laser/Hutch-1_VIEWMARQ_laser_hazard_armed.jpg :align: center :scale: 20 % **Figure 10:** Hutch-1 Control VIEWMARQ showing DANGER LASER HAZARD - ASTRELLA ARMED. .. figure:: /images/user_docs/Hutch-1_laser/Astrella_enclosure_armed.jpg :align: center :scale: 20 % **Figure 11:** Astrella enclosure showing the room interlock module armed. ----- Administrative Override on the Astrella Enclosure ------------------------------------------------- #. Turn the Astrella LASER ENCLOSURE INTERLOCK protocase INTERLOCK OVERRIDE key from INTERLOCK to OVERRIDE. The STATUS lamp will not change. #. With Hutch and Astrella armed, turn the Astrella LASER ENCLOSURE INTERLOCK protocase INTERLOCK OVERRIDE key from INTERLOCK to OVERRIDE. The STATUS lamp turns :red:`red`. #. VIEWMARQ in Hutch-1 Control displays :red:`DANGER LASER HAZARD - ASTRELLA ARMED - ASTRELLA ADMIN OVERRIDE`. #. Beacon stacks show white and :orange:`orange` LEDs activated. - a. Hutch-1 Control - b. Astrella LASER ENCLOSURE INTERLOCK protocase #. Open the Astrella enclosure door. The laser warning module displays :red:`DANGER LASER ON`, and the Door/Curtain Monitor shows :green:`CLOSED`. #. Close the Astrella enclosure and arm CONTROL #1 local interlock module, it lights the LED for :orange:`LOCAL CONTACTS ARMED`. #. Open the Astrella enclosure. "MANUAL\_" is flashing on the shutter controller. .. figure:: /images/user_docs/Hutch-1_laser/Hutch-1_VIEWMARQ_override.jpg :align: center :scale: 20 % **Figure 12:** Hutch-1 Control VIEWMARQ showing DANGER LASER HAZARD - ASTRELLA ARMED - ASTRELLA ADMIN OVERRIDE. .. figure:: /images/user_docs/Hutch-1_laser/Astrella_override.jpg :align: center :scale: 20 % **Figure 13:** Astrella enclosure showing the INTERLOCK OVERRIDE panel set to OVERRIDE. ----- Safe Astrella E-Stop Test ------------------------- #. Put the Astrella into a powered down state. #. Arm the Astrella and Astrella enclosure. #. Press one of the Astrella enclosure e-stops. #. Verify that the Astrella power supply is cut off. ----- Crashing the Astrella --------------------- #. Once every 6 months, the Astrella laser emergency stop buttons are testing that they can successfully cut power to the Astrella from a functional state. Verify if the last testing date was 6 months ago. #. If 6 months have passed, arm the Astrella laser and use one the the Astrella laser e-stop to crash the laser and verify that power has been cut. ----- Return to Starting Conditions ----------------------------- #. Return the Hutch-1 laser interlock system back to starting conditions.
