1. Consult your Emerson Process Management sales office about gauges in other units.
2. Control and stability may be impaired if this pressure is exceeded (except 2503 or 2503R controller without proportional valve).
3. Except 2503 or 2503R controller, which bleeds only when relay is open at exhaust position.
