GUIDED SPECIFICATION
Use a short engineering path to expose compatibility issues before quotations are compared.
Record generator controller function, digital and analog point counts, scan-sensitive operations, local versus remote load, and expected expansion. This prevents a CPU choice based only on the initial bill of material.
Identify Modbus TCP, remote telemetry, Modbus TCP, serial links, topology, switch ownership, addressing policy, and the devices that must exchange status or commands.
Check 120/240 V AC supply capacity, concrete service pad width, terminal access, cable bend space, heat sources, ambient limits, and enclosure ingress protection before release.
Align the requested part references with datasheets, wiring guidance, applicable declarations, accessories, and agreed substitution boundaries for procurement.
“Need an Kohler Generator” leaves supply voltage, load mix, protocol, expansion, approvals, and enclosure constraints unresolved. Quotes can appear comparable while describing incompatible scopes.
A dated load schedule, one-line diagram, electrical conditions, panel envelope, destination market, and substitution rules give engineering and purchasing the same decision record.
Include known constraints. If a parameter is unknown, state that explicitly so the response can identify the remaining engineering decision instead of assuming a value.
The review does not replace facility risk assessment, functional safety validation, protection coordination, or commissioning. Published limits must be checked for the precise CPU, genset component, accessory, controller firmware, orientation, and ambient condition.
