The TRM1033 cannot directly control a two-stage KKB because its fixed control algorithm does not provide that function.
Control Limitation
The restriction is in the TRM1033 application logic, not merely its available output count. The controller is programmed for defined functions, and two-stage KKB sequencing is not included in its algorithm.
| Option | Logic model | Two-stage KKB decision |
|---|---|---|
| TRM1033 alone | Fixed application logic | Not supported |
| PR200 | User-defined logic created in OwenLogic | Use when custom two-stage control is required |
Recommended Control Architecture
Implement the application with a PR200 and define the required operating sequence in OwenLogic. The evidence does not specify stage thresholds, delays, interlocks, feedback signals, or fault behavior, so establish those requirements from the KKB documentation and the mechanical control specification before programming.
Implementation and Verification
- Document the commands, permissives, interlocks, feedback signals, and fault responses required by both KKB stages.
- Implement that sequence in the PR200 using OwenLogic.
- Verify each stage command independently, then confirm the complete staging and shutdown sequence under all specified permissive and fault conditions.
FAQ
Can a TRM1033 control a two-stage KKB?
No. Two-stage KKB control is not provided by the TRM1033 fixed algorithm.
No.
What controller can implement custom two-stage KKB logic?
Use a PR200 and create the required logic in OwenLogic. Define the staging conditions, interlocks, feedback handling, and fault response before commissioning.
