The new BSC-ISI model (isi2stagemaster.mdl) includes a DAQKill part. This part is used when one of the following condition is met:
- Rogue excitation (Voltage on the coil drivers readbacks when the masterswicth is turned off or the ISI watchdogs are tripped)
- Excessive motion on stage 1 CPS
- ISI ST1 watchdog tripped (If SUS watchdogs trip, ISI watchdogs trip too)
More details of the changes.
In the ISI models, there are 2 channels that cannot be turned off by the ISI watchdogs.
For the test I drove offsets on:
- HEPI outputs (valve drivers turned off)
- ISI outputs channels (cables unpplugged)
- The test channels of the ISI (not connected)
I tripped the stage 1 watchdog:
- The test channels of the ISI went to zero (DAQ_KILL part)
- The output of the ISI went to zero (Watchdogs + DAQKILL)
- The HEPI channels kept driving
The DAQKILL is working fine in the BSC-ISI model.
