## succbone
|
|
succbone is our "automation" system for the vacuum system of the SEM.
|
|
|
|
|
|
|
|
### Features
|
|
- Read a TPR280 pirani gauge (0-10V analog input)
|
|
- 8x relay outputs for
|
|
- Roughing pump interlock
|
|
- Diffusion pump interlock
|
|
- Emulate _Pump-Down_ push button
|
|
- Emulate _Vent_ push button
|
|
- Signal two different vacuum levels to the original evacuation controller
|
|
* Rough vacuum reached
|
|
* High vacuum reached
|
|
- Diffusion pump temperature monitoring via three PT100 sensors
|
|
- Environmental temperature & humidity monitoring (external sensor)
|
|
|
|
### Device Overview
|
|
These are the main devices powering the succbone control system. For details,
|
|
please check the wiring diagrams in [`panel.pdf`](./panel.pdf).
|
|
|
|
- `-KEB1`: BeagleBone as main control system with addonboard for PSU & analog 0-10V readout
|
|
- `-KED1`: MikroTik RB450G router as gateway to the outside and network switch
|
|
- `-KED2`: MODBUS-TCP to MODBUS-RTU bridge
|
|
- `-KEC1`: MODBUS-RTU 8x relay output and 8x digital input board
|
|
- `-KEC2`: MODBUS-RTU 8x PT100 500°C transmitter
|
|
- `-BTA1`: MODBUS-RTU environmental temperature & humidity sensor
|
|
- `-QAA1`: Contactor for the roughing pump interlock
|
|
- `-QAA2`: Contactor for the diffusion pump interlock
