Installation
Grounding
1.Ground the flow meter by connecting a grounded cable to the sensor.
Have a qualified electrician check the electrical grounding continuity between the flow meter sensor and a true earth ground; remove the cable connec- tor from the sensor and measure the resistance from the cable connector Pin B to true earth ground. Refer to FIG. 2.
If the resistance is greater than 25 ohms, check the cable ground connection. Refer to FIG. 2. Reconnect the ground sheath or replace the cable. Do not oper- ate the system until the problem is corrected.
2.Always ground the fluid supply unit, using one of the following options:
a.Mount the meter to a grounded conductive sur- face, or
b.Connect the conductive fluid hose to the meter inlet and outlet, or
c.Connect a ground wire to the meter's M6 mounting holes.
3.Never use the flow meter with an electrostatic gun isolation stand.
