INSTALLATION INSTRUCTIONS FOR (BAPI) OR (BELIMO)
SUPPLY DUCT STATIC PRESSURE TRANSDUCER (SDPC)
GENERAL:
SDPC IS USED TO CONTROL SUPPLY FAN SPEED BASED ON STATIC PRESSURE. DEFAULT FOR SDPC IS 0-2" WC TO
0-10VDC. ANY OTHER SETTING MUST BE RE-CONFIGURED WITHIN THE MAIN UNIT CONTROLLER.
IF A DUCT STATIC PRESSURE GREATER THAN 1.5"WC IS DESIRED, IT'S RECOMMENDED TO INCREASE THE RANGE OF THE
TRANSDUCER AND RE-CONFIGURE THE MAIN UNIT CONTROLLER.
INSTALLATION:
1. VERIFY DIP SWITCH AND DIAL SETTINGS ACCORDING TO CHART BELOW.
2. MOUNT TRANSDUCER ON THE EXTERIOR OF THE DUCT AT LEAST 4 FT FROM THE UNIT.
3. INSTALL SAMPLING TUBE ONTO THE DUCT AND CONNECT TUBING TO PORT "H" ON TRANSDUCER.
4. LEAVE PORT "L" ON TRANSDUCER OPEN.
5. RUN WIRING FROM THE TRANSDUCER TO THE FIELD WIRING TERMINAL (OAUTS) STRIP USING COPPER
CONDUCTORS ONLY.
6. LAND THE WIRING ON FIELD WIRING TERMINAL STRIP ACCORDING TO THE CHART BELOW.
