Pre-commissioning Checklist

General

Check that time schedules enable the intended operation at the correct times.

Check the correct operation of the interlocks by individually switching interlocked items of plant.

Check all safety interlocks, e.g electro-thermal links and emergency knocks off buttons etc.

Control Systems

Check the specified interlocking between different control systems, for example any interlocking between a fire detection system

Check that the specified temperature interlocks operate correctly, e.g low temperature frost protection.

Check for the correct sequencing control in response to varying inputs operates in the correct order and at the desired set points

Check for the correct control and operation on start-up and shutdown. Check that the defined restart routine operates correctly when power is reinstated

Check that controllers maintain settings information of the control approach for a defined duration when the energy of the mains is wasted.

Check that the condition of any volatile data protection system is regularly and automatically monitored.

Check that an alarm is raised on loss of data by any controller or other device and/or failure of the monitoring system.

Check that the control system operates correctly under generator standby and UPS power if applicable

Check that the control system will automatically return to normal action without operator intervention restoration of the mains electrical power supply

Check that any specified load shedding procedures operate correctly.

Checks on powered control machinery and circuits, including modifications for the proper functioning of security systems.

Function

The lamp test facility, if specified

Wiring interlocks by progressively energising or de-energising relay contacts, switches, timers etc in each circuit. Switches must be used to test that the system operates correctly in response to input signals.

All indicators and signals out of the panel, Safety interlocks must be checked in ‘manual’, ‘off’ and ‘auto’ switch modes

Frame size fuse or circuit breaker, sort of device journey and drawing configurations.

Correct labelling has been provided.

Trip the engine and make sure it de-energizes and lights up the travel sign.

Energize the starter / contactor by ' creating ' the control loop and guarantee that the driver is operating properly and that the outgoing terminals receive authority.

If the control panel is left on site for a long period then undertake adequate steps to ensure that it is protected from dirt, damage and moisture

Repeat the flash experiment before closing the primary isolator when the field wiring is full to the energy segment.

Check all fresh links in the board before the electricity is turned on and the interlocks are re-checked

Perform a complete panel test on-site if the panel has not been tested in the factory

Wiring

Check that time schedules enable the intended operation at the correct times.

Cable type as specified

Cable identified at both ends

Cable cores identified at both ends if not self numbered or colour coded

Cable management in accordance with the specification

Cable carrier/container in accordance with the specification (tray, basket, conduit/trunking etc)

Cables not damaged

Secure termination of wires (using ferrules)

Screening continuity

Correct polarity where applicable

Correct and secure termination

No short circuits line-to-line and line-to-earth

Separation of mains and signals cables

Site Communications Network

All network devices such as routers and bridges are installed correctly.

All control devices can be addressed over the communication network.

IT manager permission acquired?

All network data routing is correctly set up by the IT department including allocation of the appropriate TCP/IP addresses and default router addresses.

Sensors

Check that time schedules enable the intended operation at the correct times.

Correct location and orientation of the sensor

Type of sensor as specified

Sensor wired correctly

Confirm the sensor output indicated by the control system with the reading on the test instrument.

If a sensor is not linear over its working range, check the sensor at its normal working range at the upper, middle and lower points

Field Control Devices

Type as specified

Size as specified

Enclosures as specified

Number and location (height, access) as specified

Identification by mnemonic labelling

Continuous power available and of an appropriate quality

Fuse correct type/spares if specified

Hardware configuration agrees with the specification

All printed circuit boards in place

All connection cables plugged in

Document wallet containing wiring diagram where appropriate, i.e when located in a control panel

Completion

Pre-commissioning Checklist

Created by: SafetyCulture Staff | Industry: General | Downloads: 1

A pre-commissioning checklist aims to prepare a manufacturing plant for start-up, or when all new or modified systems are going live. Use this checklist to easily inspect control systems, wiring, sensors, field control devices, and the site communications network.
