| | ===== Guide Box Y Axis as of December 2022 ===== |
| | |
| | A new type of error has started showing its ugly head in mid-November. It usually starts with the Y axis of the |
| | guider camera's 3-axis translation stage. For example, the command is to move from 0 to +65. Motion stops at +35. |
| | |
| | **Solution.** Cycle power on the MOXA serial-to-ethernet media converter: In the Dome, pull the power-over-ethernet cable (orange) out of the Moxa unit and plug it back in. In Control room, run ''Initialize'' and ''Reference'' from the user Secondary-and-Guider GUI. |

| The ''Air Temp'', ''Strut Temp'', ''Mirror Temp'', and ''Mirror Air Temp'' (the ''Thermal'' tab in ''TCSglue'') may again be regarded as **reliable**. | The ''Air Temp'', ''Strut Temp'', ''Mirror Temp'', and ''Mirror Air Temp'' (the ''Thermal'' tab in ''TCSglue'') must be regarded as **unreliable**. |

| 8-) First, run the thermal control system ([[vatt:vatt_neslab|NESLAB]] [in the silo] + cell fans [GUI] + TCSglue [GUI]) to bring the M1 temperature down at the beginning of the night, using the ''Set point'' mode. Then, during the night, leave the system running in the ''On'' mode. | 8-) First, run the thermal control system ([[vatt:vatt_neslab|NESLAB]] [in the silo] + cell fans [GUI] + TCSglue [GUI]) to bring the M1 temperature down at the beginning of the night, using the ''Set point'' mode. Then, during the night, leave the system running in the ''On'' mode. |
| |
| Example. Sunset is at 19:30. At 17:00 TCSglue sees the ''Air Temp'' as 20°C, and the ''Mirror Temp'' as 14°C. The actual ambient temperature at 19:30 will be around 12°C. At 17:00 open the dome slit, and start the large dome fan to evacuate the accumulated hot air. Turn on [[vatt:vatt_neslab|NESLAB]] (in the silo) and the cell fans (control room with ''TCSglue''). At 18:00, activate the thermal control code, using a set point of 12°C. After about an hour, mirror temperature ought to be approaching the set point, bringing the temperature difference with respect to ambient within the safety limit (ΔT<5°C). For the remainder of the night, switch to the ''On'' mode (TCSglue [GUI], ''Thermal'' tab, ''On'' radio button). | Example. Sunset is at 17:30. At 16:30 TCSglue sees the ''Air Temp'' as 0°C, and the ''Mirror Temp'' as 1°C. The actual ambient temperature at 18:00 will be around -4°C. At 16:30 open the dome slit, and start the large dome fan to evacuate the accumulated warm air. Turn on [[vatt:vatt_neslab|NESLAB]] (in the silo) and the cell fans (control room with ''TCSglue''). Activate the thermal control code, using a set point of -4°C. After about an hour, mirror temperature ought to be approaching the set point, bringing the temperature difference with respect to ambient within the safety limit (ΔT<5°C). For the remainder of the night, turn off the thermal control system (TCSglue [GUI], ''Thermal'' tab, ''Off'' radio button; turn off [[vatt:vatt_neslab|NESLAB]] (in the silo) and the cell fans using ''TCSglue''). |
| | |
| | Note that about 5-10 minutes after you turn off the thermal control system, there will be a significant jump in the ''Air Temp'' and ''Strut Temp'' values and a slightly smaller jump in the ''Mirror Temp'' and ''Mirror Air Temp''. A few cycles later the values will stabilize and become realistic. |

| You may use a new ''Watchman'' wifi device for independent measurements of temperature and humidity in the dome. It is plugged in (it needs 5V power) by the flood lamp and the dome cameras (legacy and HikVision). This is "dirty" power, which means that the device is available during lightning shutdowns. | You may use a new ''Watchman'' wifi device for independent measurements of temperature and humidity in the dome.

| | |
| | Note that the ''Input Select'' in the monitor's main menu must be set to ''Auto'' (see p. 21 of the manual). When this is the case, the monitor reliably finds the source (HP Thin Client or a laptop attached to the ''HDMI 2'' port). :!: Make sure that the ''Input Select'' is set to ''Auto'' :!: |
| | Also note that the multipurpose button can be used (pushing it upwards) to activate a simple source selection menu (see p. 12 of the manual). When you do use the simple source selection menu to select a source, however, go back to the main menu and make sure that the ''Input Select'' is set to ''Auto'' because selecting a source with the small menu changes the settings in the main menu. |
| | |
| | Note that there is a power switch at the bottom of the monitor next to the socket for the power cord. |
