Phase Template: set-jacket

Set the reactor jacket heating/cooling output (0-100 %). It is a single-action building block that writes the output and completes. Write 0 to turn the jacket off.

Where to find it

System endpoint → Equipment Library → Phases → select set-jacket.

How it works

The phase has a single execute step. It writes output to jacket_controller.CMD and the phase completes. The jacket stays at that output after the phase ends, until a later step changes it. The holding, stopping, aborting, and resetting charts zero the jacket (heater off on any interruption). The restarting chart re-applies output.

This is a single-action phase. There is no temperature endpoint. A jacket left at a fixed output is an open-loop heat source. Pair with a high-temperature alarm on the vessel, and use react (which adds a maxTemp interlock) or cip-heat-and-hold (which waits on a temperature target) when the recipe needs closed supervision.

Used in recipes

No shipped reference recipe uses this template. It is a building block for composing your own.

Try it

1. System endpoint → Recipes → create a draft recipe with a set-jacket step on reactor-1 (the jacket_controller role binds to r1-jacket)
2. Approve and start it from HMI endpoint → Batch Execution
3. Open Data endpoint → Trends on the reactor temperature sensor and watch it rise while the jacket holds the commanded output
