Appears that they would not cycle due to setpoint being outside of Hmin/Hmax range. Reset those under direction of DC Power and this seems to have solve the issue

Performed a hard reboot of ioctsbhrp.

Ran several test scans for IHA5C11.

The test scans show the harp carriage leaving the "OUT" limit position and engaging the "IN" limit switch. The encoder read backs show the starting position of 11mm and a fully inserted position of 90mm. We turned the pre-amp test signal on and verified the response of the ADC read back.

The hard reboot cleared the "stuck" state the harp was in. 5C11 is fully operational.

All is well. Today, reviewing recent performance of the source.

The QE is fine (>0.5%) for the foreseeable future although lifetime (<50C) is low, let's discuss at this week's group meeting.

The Hall A and C laser powers are ~200 mW.
The Hall B and D laser powers are ~20 mW.

Gun HV chamber system looks good, note bias is on locally at +1kV.

Hall C requested slit current management, but could not make 1uA this way, so managing current with attenuator.

Replaced +Bulk and -Bulk fusing for channels 29-32. Turned rack on and ramped up bulk supplies. Check bulk voltages using an extender card. Inserted (4) new TC3. Setpoints taken and cycled with no issues. We will inspect the TC3 that were removed from the rack for any issues
