The instrument can be installed, wired, and place directly into operation. 1.1 Probe Installation Insert the probe into the pipe or duct at the appropriate location. It is recommended that the sensor be located on the center line of the pipe and that the flow arrow be posi- tioned in the direction of flow. See Appendix 1 for recommended upstream and down- stream distances. 1.2 Wiring Warning: Explosion Hazard. Do not connect or disconnect equipment unless power has been switched off or the area is known to be non-hazardous. NOTE: Make sure the electrical wiring to the TA2 is complete and in compliance with all regulations and codes. For a maximum ambient temperature of 80° C use wiring rated up to 264 VAC and 105° C. For a maximum ambient temperature of 70° C use wiring rated up to 264 VAC and 95° C. 1. Remove the cover of the wiring compartment. 2. Pull power supply and control wiring through conduit connection. 3. Connect power leads to proper terminals. a. 100 to 260 VAC – Make connections to TB1. Connect the “hot” wire to L1 and the second wire to L2. b. 11.6 to 29 VDC – Make the connections to TB2. Connect the Positive wire to (+) and the negative lead to (–). NOTE: Ensure that the correct wiring is made to the appropriate ter- minals. Connecting the DC power to the AC terminals will cause the unit not to operate. Connecting the AC power to the DC terminals will blow the fuse and potentially cause damage to the electronics boards. NOTE: The green ground screw in the rear of the housing should be used for earth ground. 4. Connect the 4-20 mA signal wiring to TB3. Make connec- tions to A-, A+ for an active output signal (power supplied by TA2) or P-, P+ for a passive signal using an external power supply. |
