Which mechanical details should an interface schedule record?
Record reference coordinates, top-of-surface heights, horizontal and vertical gaps, product direction, usable width, guide transitions, support across the gap, frame and leg clearances, mounting method, adjustment range and who supplies the transfer components. Include the product state used to approve the detail.
A plan, side elevation and local detail may all be needed where one view cannot show the complete boundary.
Which electrical and control signals should be recorded?
Record power supply and isolation boundaries, signal names, direction, electrical format, normal state, fail state, ownership, terminal or network reference, timing and required response. Typical process signals may include ready, run permit, product present, blocked, fault and reset permission, but the actual schedule must follow the agreed line sequence.
Do not rely on identical signal names if the two machines interpret them differently.
How should responsibility for each interface be assigned?
Assign separate owners for design approval, component supply, mechanical installation, field wiring, software, guarding, validation and final acceptance. A single “by others” note is not enough when several parties are involved. The named organisation or role should be able to confirm the deliverable and its evidence.
Responsibility should be agreed before manufacture so missing work is not discovered during installation.
How should interface changes and test evidence be controlled?
Give the schedule a revision, date and approval status, and link each interface to the current drawing, I/O record and acceptance test. A change to product, height, gap, speed, signal or responsibility should create a visible revision and identify affected equipment. Test results and approved deviations should reference the same interface number.
Keep superseded records for traceability but make the current approved issue unambiguous.
