A-IEF-IDSP-RM
The Series A-IEF Remote Display can be installed almost anywhere near a Series
IEF ow transmitter or IEFB thermal energy meter. Both the indicator display (A-IEFIDSP-RM) and the full functional display (A-IEF-FDSP-RM) have a maximum display
cable length of 100 ft (30 m) to permit easy viewing of ow readings. The full functional
display allows for convenient adjustment of conguration settings and allows the user
to save the IEF or IEFB conguration settings to a computer for printing.
FEATURES/BENEFITS
• Full functional display can be used to set up the IEF/IEFB and adjust the settings if
it is installed in a hard-to-reach location.
• Indicator display makes it convenient to read process values if the meter is
inaccessible.
• Varying cable lengths of up to 100 ft (30 m) allows for exible installation on a wall or
pipe mount.
• Easy to install and wire in the eld.
APPLICATIONS
• Mechanical rooms with a small footprint
• Hard-to-reach piping
• Boilers and chillers
• Chilled water
• Condenser water

INSTALLATION
The Series IEF/IEFB can support one display. If the IEF/IEFB has the local LCD display
option (-LCD), the display will need to be replaced by a blank cover (blank cover
offered separately, part number A-IEF-LID). The remote display must be connected
to the IEF/IEFB owmeter with an eight conductor shielded cable (maximum length of
100 ft (30 m)). The provided adapter PCBA board will need to be installed in the IEF/
IEFB owmeter to connect to the remote display cable. For installations where the
remote display is attached to a pipe, the included pipe clamps should be used.
Note: The power to the IEF/IEFB must be turned off before installation of the remote
display.
Mounting the Remote Display
Locate an appropriate location that allows for visibility of the remote display. The
remote display is suitable for mounting on a at surface or mounted to a pipe in any
orientation; clamps are supplied for pipe sizes 3˝ to 12˝ (76.2 to 304.8 mm).
Surface/Wall Mount
To mount the remote display to a at surface such as a wall, hold the remote display in
the desired location, mark hole locations on the at surface using the attached bracket
as a template, drill holes and mount the remote display with screws suitable for surface
and bracket slot dimensions.

WIRING
Remote Display Cable Installation and Wiring
The cable connecting the remote display to the Series IEF or IEFB will wire into two
removable terminal blocks located on the back of the remote display lid.
The cable will need to have a sufcient service loop inside the remote display for easy
access [9˝ (22 cm) is recommended]. Similar to the IEF/IEFB, the cable wires should
be stripped approximately 0.22 in (5.59 mm). A 1/8˝ slotted screwdriver can be used to
tighten the terminal block screws. For Dwyer Instruments plenum cable A-IEF-CBL-X,
the recommended colors codes are:

REMOTE DISPLAY LID
Note: Use the USB connector near the terminal blocks to connect the display to a
computer in order to to print out the conguration values for the IEF/IEFB (supported
on the full functional display only). See the IEF/IEFB manual F-IEF-F or F-IEFB-F for
details.
Note: For full functioning display A-IEF-FDSP-RM if the display lock out feature is

In order for the remote display to operate an adapter PCBA board, shown below, must
be installed in the display port of the Series IEF or IEFB.
Figure 7: Adapter PCBA board
The terminal block wire entries face the center of the cover. After connecting the cable
to the remote display, use a 3 mm Allen wrench to remove the tether-mounting screw
from the IEF/IEFB and install the remote display cover to the housing (The cover has
four screws).
Using the supplied 3mm Allen wrench, begin by unscrewing the (4) captured screws of
the Series IEF or Series IEFB to remove the lid from the enclosure.
Note: The lid is tethered to the IEF/IEFB enclosure to allow for convenient wiring. The
lid is only tethered in the base unit.
Mount the adapter board and afx to the Series IEF or IEFB by screwing in supplied
screw to the stand off as pictured below.

Feed the remote display wiring cable into the Series IEF/IEFB housing through the
grommet, as shown below. Connect to the removable terminal blocks located on the
adapter board.

IEF/IEFB Cable Installation (cable gland option):
If the IEF/IEFB has a cable gland option with a 2 hole grommet, insert the included
3 hole insert. First, disconnect the A and B cables from the IEF/IEFB terminal blocks.
Fully loosen the cable gland nut onto the A and B cables. Remove the cables from the
IEF/IEFB. Remove the two hole cable gland insert and install the included 3 hole cable
gland insert. This will allow each cable to be installed in the IEF/IEFB.
For easier installation, insert the remote display cable, the A cable, and the B cable at
the same time. Connect the A and B cables to the IEF/IEFB terminal blocks (See the
IEF/IEFB manual F-IEF-F or F-IEFB-F for details.) After connecting the A and B cables,
the IEF/IEFB PCBA adapter board can be installed.
Once the wiring of the remote display is complete, install a blank cover on the IEF unit
(not a LCD cover). Use a 3 mm hex key to tighten the four cover screws.

required. The display is not eld serviceable and it is not possible to repair the unit.
Field repair should not be attempted and may void warranty.
Power must be supplied to the IEF/IEFB prior to this unit being operational.
