# DEMO DOCUMENT — NOT A CONTROLLED DOCUMENT — DO NOT USE ON PLANT

Document number: WRPS-DEMO-001
Title: Temporary Bypass of Pump Motor Protection Interlock
Revision: 0
Effective: 2026-01-01
Authorising role: Station Maintenance Supervisor

## 1. Purpose

This fabricated document exists so that the Procedural branch of the plant
assistant has a procedure-shaped thing to locate during a no-LLM demonstration.
It describes, in invented terms, the temporary bypass of the motor protection
interlock on pump PU-302 at the Waterloo Road Pump Station.

Nothing in this document is a real instruction. It has not been reviewed, it
has not been approved, and no hazard assessment sits behind it.

## 2. Prerequisites

The following must all be confirmed before this fabricated procedure begins.

- A permit to work has been issued and is held by the person carrying out the work.
- PU-302 has been electrically isolated at MCC-501 and the isolation proven dead.
- The duty selection has been transferred so that PU-301 and PU-303 can meet inflow.
- The wet well WW-101 level is below the start-duty level and falling.
- The Station Maintenance Supervisor has authorised the bypass in writing.

## 3. Procedure

1. Confirm every prerequisite in section 2 is satisfied and recorded.
2. Log in to the station HMI with a maintenance-level account.
3. Navigate to the PU-302 faceplate and select the protection tab.
4. Set the motor protection bypass to ENABLED and confirm the prompt.
5. Record the bypass in the station log with the time and the permit number.
6. Carry out the authorised work.
7. Set the motor protection bypass to DISABLED before returning PU-302 to service.

## 4. Restoration

Restore the duty selection and confirm PU-302 responds to a test start. Close
the permit. Record the restoration time in the station log.
