LAMINATOR_NIP_CTRL
Laminator nip pressure and roll-temperature control with nip-open interlocks, over-temperature cutout and a laminate-ready permissive.
When to use it
Use LAMINATOR_NIP_CTRL when a heated laminating or sealing nip has to hold a loading pressure and a roll temperature while product runs, and the nip must open and the heat must fail off whenever the web stops or a measurement is lost.

Supervised control write
LAMINATOR_NIP_CTRL commands a real actuator. It is written to sit underneath your own interlock, permissive and protection logic — not to replace it. Commission it as you would any control block you wrote yourself.
