Cable/RTD/Signal Maps
NOTE: If you update a map below Click on a the previous hclog entry and either add a comment pointing to your new entry, or use the 'Follow-up' link on the old entry to make a new entry. That will make it easier to track when/why things change.
- Note: There is a dictionary of EPICS PVs with descriptions at
- ~coda/coda/scripts/EPICS_logging/polhe3-epics.txt
- Laser Fiber End RTDs:

Fiber RTD hardware trip points
- Fire Safety RTDs
- HcFiberTemp0, HcFiberTemp1
- max measured about 32C
- set trip to 36C
- Fiber Temperature RTDs
- HcFiberTemp4+ (except for 12, 14 below)
- Max measured of about 32C

- Max measured of 40C
- set trip to 46C
Reset instructions for RTD HW trip points • Expert only (Brad or Ethan) [click]
Address 0xF6 FiberTemp0-1: (and the unused 2, 3) Fire safety RTDs (max 36) Address 0xF5 FiberTemp4--7 * max 36 Address 0xF3 FiberTemp8--11 * max 36 Address 0xF4 FiberTemp12-15 * max 46 due to 12, 14
NOTE: power cycling the acromag controller below will trip the laser interlock!
- Set the hardware trip limits
% ssh pi@polhe3pi2 ('hccuser' password) % cd Documents % scls # select 'acromag' entry, then type Ctrl-C to kill the program # Set the limits % for f in 0xf3 0xf5 0xF6; do ./setupAcro -l 36 -a $f; done % for f in 0xf4; do ./setupAcro -l 46 -a $f; done # Reboot the acromag controller using hcreboot6 # Then restart the software by (for example) running bash again % bash
- Verify that the stripcharts are updating again and close the terminal window.
PolHe3 Alarm Handler defaults
These can be reset this way:
% ssh cvxwrks@cdaql1 % cd alarm_handler_polhe3 % ./set_polhe3_defaults
