Installation - Dwyer Instruments IEF Series Specifications-Installation And Operating Instructions

2. Select a location that will minimize flow distortion with adequate upstream and
downstream pipe diameters as displayed. Ideal installation will have a minimum
of 10 pipe diameters upstream relative to the instrument and a minimum distance
of 5 pipe diameters downstream.

INSTALLATION

1. To prepare the meter for installation, mount the provided alignment scale to the
side of the meter with the two provided thumbscrews. The thumbscrews are to be
inserted through the alignment scale slots and into the holes in the side of the lid
as shown in Figure 4, finger tighten only. Be sure to orient the alignment scale as
shown in figure below. Actual scale setting determined in next step.
For Custom Configured Models (-CC Option)
2. Locate the configuration tag attached to the Series IEF to identify the value of
the alignment scale setting. Position the alignment scale such that the scale
setting is lined-up with the seam of the enclosure as shown in Figure 4. Minor
scale marks are in 1/20ths Securely tighten the thumbscrews.
3. Refer to Preparing the Unit for Installation section.

For Field Configurable Models
2. For field configuration, a display is required (-LCD option or accessory A-IEF-
DSP) and needs to be powered via normal field wiring or with the AC wall adapter
accessory A-IEF-PA ( A-IEF-DSP and A-IEF-PA are also available in the
accessory setup kit A-IEF-KIT).
3. When using the AC wall adapter and the cable is supplied, connect the red
(positive +) and black (common -) wires of the cable bundle marked "A" to the
open terminals of the AC wall adapter. This will provide temporary power to the
meter to complete the installation set up.
4. For field wiring, refer to the wiring chart tag attached to the Series IEF to identify
the terminal block pins for positive (+) and common (-) connection.

5. Unscrew the four captured cover screws using the supplied 3 mm Allen wrench
to remove and set aside enclosure cover.
6. Insert one connector of the ribbon cable supplied in the setup kit into the
connector labeled "Display" in the middle of the unit. Be sure to orient the keying
feature/tab. See Figure 5 below:

7. Plug the other end of the cable into the bottom of the supplied portable display
being sure to orient the keying feature/tab as shown:
8. Apply power to the unit and the display will turn-on automatically. Follow the on
screen directions for entering the necessary parameters to setup the unit and
obtain the alignment scale setting value.
