This morning during the maintenance monitor cables were added to the output of the north and west heating belt power supplies to monitor the voltage sent to the actuators. The following channels are now available:

• LSC_NI_HB_moni
• LSC_WI_HB_moni

Also, the clipped voltages were measured by using the analog gauge on the front of the power supply. The north was clipped at 22 V (at 10 A) as expected. The West was clipped at 18 V instead of the expected 22 V. After the maintenance we then realized that the voltage was clipped by the PyALP process which was controlling the west etalon control (the north had already migrated to Acl control). It is anticpated that the clipping voltage will be 22 V when not clipped by PyALP.
