[Dsg-hallb_magnets] Readout of the status of the guard vacuum pump

[George Biallas]

Pablo, 
Thank you very much for the follow-up. 

With regard to Item 3, I thought that I was just not knowledgeable enough to read the literature - that you instrument folks would know right away. I was wrong. 

So, indeed the MOOG Controller folk just don't compose good product descriptions. Yes, please contact them.

| Hello Ruben,

| See my answers in blue:

| 1. I understand from Renuka that PT8677 is already being monitored by the PLC -
| is this correct?

| Yes, the readout signal for the PT8677 (Guard Vacuum) pressure is already
| monitored by the PLC and also appears in the Solenoid wiring drawing
| B00000-900-0626.

| 2. Which screen is PT8677 presently being displayed on? We will need it
| displayed on the Cryo screen.

| The PT8677 is currently displayed on the EPICS Helium-SST screen.

| 3. We will also need an 'indicator' located next to the PT8677 to provide 'pump
| motor status'

| I shall look through the information George has sent round to determine what
| form this status will take and will let you know.

| Is there a spare PLC channel to allow inclusion of this status?

| I already looked into the information sent by George Biallas and I cannot found
| any useful information to determinate the type of the output signals of the
| guard vacuum pump controller (MOOG- BDO-Q2-50-40). To my understanding
| typically these outputs signals: S1 (Hall Switch #1) and GND (GND for hall
| sensors #9) used to be aware of the status of the guard pump; gives pulse train
| signals (Discrete Signals), but there is nothing in the manual to confirm that.

| So maybe I can contact to the vendor of the controller and confirm this aspect,
| and then I can determinate if we have any spare available in the PLC input
| modules to be used to monitor this signal.

| Best Regard

| Pablo

| Scot

| Could you please work with Mark to get the relevant cables made?

| Pablo

| Can you implement this in the PLC and work with Wesley to get the EPICS screen
| updated? Also remember to update the relevant spreadsheets and then work with
| Renuka to get the docs updated.

| Also speak to Joe Matalevich to see what alarms and/or controls he needs setting
| up.

| Regards

| Ruben
