Controller task definition
Prepare pressure task description for the controller task definition review. Identify each intended instrument and its pressure requirement separately in the request. Ask which equipment configuration addresses that requirement, and request the corresponding specification rather than combining different instrument requirements into an unspecified pressure equipment description. Ask which control requirements should the buyer submit for review?
Request or submit instrument requirements, according to the proposed purchase scope. Describe the information being requested and identify the equipment concerned. Request the corresponding technical document for the proposed item, and ask which specific parts of the buyer requirement are addressed so the response can be compared with the intended purchase scope.
Controller specification questions
Prepare version specific data sheet for the controller specification questions review. Provide an example of the buyer record format or describe the required information fields. Ask which records the proposed configuration can provide and in which form, and request clarification of any additional item needed to address the stated document requirement. Ask which stated functions belong to the proposed controller?
Request or submit configuration description, according to the proposed purchase scope. Describe the intended task and request a written description of the proposed configuration. Ask the supplier to identify the included functions and any separately quoted items, then compare that scope with the buyer task requirements before closing the equipment enquiry.
Controller interface review
Prepare connection drawings for the controller interface review review. Identify each interface and the item connected to it in the buyer drawing. Request the corresponding interface information for the proposed equipment, and ask for any separately required component to be identified before comparing the proposed configuration with the existing installation. Ask which interfaces should be checked before integrating the controller?
Request or submit system interface requirements, according to the proposed purchase scope. Identify each interface and the item connected to it in the buyer drawing. Request the corresponding interface information for the proposed equipment, and ask for any separately required component to be identified before comparing the proposed configuration with the existing installation.
Controller proposal comparison
Prepare supplier response sheet for the controller proposal comparison review. Name the requirement that needs a written answer and identify the proposed item concerned. Request clarification against the buyer document rather than a general category description, and compare the response with the same requirement when considering an alternative equipment configuration. Ask which configuration differences require written clarification?
Request or submit included item list, according to the proposed purchase scope. Name the requested item and distinguish the main equipment from separately requested components. Ask the supplier to identify the corresponding items in the proposal, and confirm minimum order quantity and lead time before ordering against the agreed configuration and receiving requirements.
