Procedure Steps#
First step is to check if the E-stop is engaged. If it is engaged, release it using the procedure linked in step 2 and attempt to enable ATCS again.
The only way to check if the E-stop is engaged is from the ATMCS EUI. The ATMCS EUI can be opened from a remote desktop connection or from the control computer at the first floor of the AuxTel dome. More detailed instruction in the access ATMCS EUI procedure.
Open the LSST Auxiliary Telescope MCS & Pneumatics window and under Mount tab, the Emergency Stop indicator will be red and reading E-stop, if the E-stop is engaged.
