[. . . ] Instructions-Parts Coriolis Meter Kit 313599C ENG For use with Graco ProMix 2KS Proportioners. Uses vibration to measure fluid flow in low flow applications or with light viscosity, shear sensitive, or acid catalyzed materials. Bare meter is approved for use in explosive atmospheres [Class I, Div I, Group C and D, or Class I, Zone I, EExd(ia) IIC T1-T6] if all installation requirements are met. (3 mm) diameter metering tube 2300 psi (16 MPa, 160 bar) Maximum Working Pressure Part No. [. . . ] Install the strain relief (12). See Hazardous Location Intrinsically Safe Installation Requirements on page 5 and FIG. Install the power cable according to all local electrical codes. Do not operate proportioner with equipment enclosure doors/covers open. Disconnect power source before servicing or doing electrical wiring. Turn proportioner power off and disconnect power source. Bring the user-provided power cable (PC) from the hazardous area into the non-hazardous area. Power Supply Circuit Requirements 24 Vdc at 1 Amp is required to power the meter, which is more power than an intrinsically safe circuit can provide. The 24 Vdc can be supplied from the EasyKey. · Installation of the power input circuit (PC) in the hazardous location must comply with all local and national electrical code requirements relating to flameproof or explosion proof methods of protection. · Required electrical components to complete a compliant hazardous location installation of the power input circuit to the meter are not provided with the meter kit. * For P/N 15T633 order Coriolis Meter Kit 15V806. For P/N 15T634 order Coriolis Meter Kit 258151. FIG. System Layout for Coriolis Meter (B Side Meter Installation Shown) 313599C 9 Installation Meter Signal Cable 1. Route the 20 ft (6. 1 m) signal cable (4) into the fluid panel and through a strain relief (SR) on the left side of the fluid panel enclosure. Connect the signal cable's green ground wire to the ground terminal bar (GT). Connect the white and black wires to J3 on the fluid panel control board (CB). Use pins 2-3 for Flow Meter A and pins 5-6 for Flow Meter B. The signal cable (4) must be connected to the Coriolis meter with a Zone I Ex d IIA or Class I Div I cable gland. 5.

Signal Cable Connections at Fluid Panel Board 10 313599C Installation Power and Signal Cable Connections at Meter The signal cable (4) is factory assembled to the meter. If cables need servicing or replacement, see FIG. 7 to connect to meter. Grounding Your system must be grounded. Never use the flow meter with an electrostatic gun isolation system. -27 +26 -25 +24 -23 +22 -21 +20 4 Flow Meter Sensor Ground the flow meter sensor by connecting the signal cable ground wire as shown in FIG. Have a qualified electrician check resistance between the flow meter sensor and a true earth ground.
