SRVO-009: Pneumatic pressure alarm
The controller's pneumatic pressure input (PPABN) says air pressure is abnormal.
What it means
The controller's pneumatic pressure input (PPABN) says air pressure is abnormal. On cells that monitor air supply this usually means exactly that - low or lost air. If the air is fine, the PPABN signal wire is sitting at 0V.
Common causes
Ranked by what technicians most often find, most likely first.
- Actual low or lost pneumatic pressure to the cell.
- PPABN signal wire in the robot connection cable faulted to 0V.
- Signal enabled in config on a system that doesn't monitor air.
How to fix it
- Check air supply, regulator, and any dump valve; restore pressure and press RESET.
- With good air, check the PPABN wiring in the connection cable.
- If the system genuinely doesn't use the pneumatic monitor, disable the PPABN setting in SYSTEM > Config instead of tolerating a nuisance alarm.
