moderate pressure, pressing squarely on the drill, and retracting the bit from time
to time to clear the chips and cool the bit. After drilling the holes, remove any
burrs that were formed and make sure the pipe is reasonably smooth in the area
around the holes. Apply the “Holes in Pipe” decal so that it will be hidden when
the meter is in place but will be revealed when it is removed.
Installing the Meter
First prepare the meter for the pipe orientation and the direction of flow. To
switch the 5400 between horizontal and vertical orientation, loosen the screws on
the back of the housing, rotate the display, then re-tighten the screws. Be careful
to loosen the screws no more than necessary, and then tighten them securely.
The flow arrow on the meter must be oriented to match the direction of flow in the
pipe. If doing so will cause the display to be upside-down, remove the cover of
the meter, lift out the display, rotate both 180° and re-install.
Now mount the meter on the pipe and tighten the cap screws evenly. The torque
should be sufficient to seal the gasket but not so great that it will crush the gasket
or distort or over-stress a thin-walled pipe.
Wiring the Meter
Wiring must be in accordance with applicable codes and standards. In areas
where electrical interference may be present, signal wiring should be shielded
with the shield grounded remote from the meter. Signal cables must not be run in
conduit or cable trays shared with power wiring. The main terminal block inside
the meter is accessed by removing the cover and lifting out the display circuit
board.

Either use the dc wall-plug supply furnished with the meter, or connect the
terminals marked “24V dc” to a distributed dc power supply and seal the unused
power opening with the plastic plug provided. The meter will draw a maximum of
250 mA. Unlike earlier 5200 and 5400 meters, the Rev. 3.0 meters do not
connect the dc- terminal to the pipe on which they are mounted. Please note that
18 Volt dc supplies furnished with some earlier CDI flowmeters do not provide
the voltage required for Rev. 3.0 meters.

If you are using the summing remote display (SRD), connect the three terminals
marked “display” to the corresponding terminals in the remote display. The meter
may be powered from the remote display if the cable is 22 gauge or heavier and
the distance is no greater than 200 feet.

The 4 - 20 milliamp output is optically isolated within the meter and it is provided
with a factory-installed jumper which allows it to source a milliamp signal
powered from the meter. The resistance of the loop connected to the output
should not exceed 600 Ohms.

The pulse output is open-collector, that is, a transistor switch to the meter’s
negative supply. To use it, connect it to the input of the receiving device; also
connect that input through a 10K Ohm resistor to a suitable positive supply and
connect the negative supply of the receiving device to the negative supply of the
meter. If an isolated relay contact is required, install the CDI 5200-IPO isolated
pulse output and wire it to the receiving device.

The RS-485 signal used with the Serial Communication option is wired to the
special Serial Communication display board. The two threaded openings in the
meter enclosure permit the signal to be wired from meter to meter without
external splices. Please refer to the data sheet for the Serial Communication
option.
