6 LED LIGHTS: The RED LED on top of the unit illuminates showing that power is supplied to the unit. Models with monitor optional or TTL. signal have a GREEN LED in addition to the RED LED. The GREEN LED illuminates when the device is satisfied, output is within 1% of the set point. The unit may pulsate while settling in due to the compressibility of the media and the pneumatic circuit. This is normal under static conditions. TABLE 1. RATED INLET PRESSURE FOR STANDARD BB valves . For valves ordered with MAX. calibrated Max. inlet pressure is: pressure of: Vacuum up to 10 psig ( bar) Consult factory up to 30 psig ( up to 2 bar) 35 psig ( bar). 31 up to 100 psig ( up to 7 bar) 110 psig ( bar). 101 up to 175 psig (7 up to 12 bar) 190 psig (13 bar). 176 up to 300 psig ( up to bar) 330 psig ( bar). 301 up to 500 psig ( to bar) 550 psig ( bar).

7 NOTE: valves with options S67, S91, or S106 can handle higher inlet pressures. Inlet pressures are not the same for valves mounted to volume boosters. Consult factory for further information. 2 INBB1-BB2. 06/09/06 NK. ELECTRICAL CONNECTIONS. 1. Turn off all power to valve. 2. Identify the valve's command input and analog output using the calibration card included in the package and the order- ing information section on the last page of this sheet. 3. Proceed to the appropriate section corresponding to the type of valve being installed.
