Mounting Dimensions

Refer to Honeywell drawing number 50094836 for detailed electronic housing dimensions.
Refer to Honeywell drawing numbers 50095917 for detailed pipe mounting dimensions and
50095918 for detailed wall mounting dimensions. Abbreviated overall dimensions are also
shown on the Specification Sheets for the Remote Indicator models. This section assumes
that the mounting dimensions have already been taken into account and the mounting
area can accommodate the Remote Indicator.

Bracket Mounting

If you are using an optional bracket, start with Step 1.
1.
Align the two mounting holes in the Remote Indicator with the two slots in the
mounting bracket and assemble the (2) M8 hex cap screws, (2) lockwashers
and (2) flat washers provided. Rotate Remote Indicator assembly to the
desired position and torque the M8 hex cap screws to 27,0 Nm/20,0 Lb-ft
maximum.
Pipe Mount Option: Refer to Figure 2
2.
Position the bracket on a 2-inch (50.8 mm) horizontal or vertical pipe, and
install a "U" bolt around the pipe and through the holes in the bracket. Secure
the bracket with the nuts, flat washers and lock washers provided.
3.
Wall Mount Option: Position the bracket on the mounting surface at the
desired location and secure the bracket to the mounting surface using the
appropriate hardware (Wall mounting hardware requirements to be
determined and supplied by the end user)

ATTENTION
Wiring must comply with local codes, regulations and ordinances.
Grounding may be required to meet various approval body certifications,
for example CE conformity. Refer to Appendix A of this document for
details.

Wiring Procedure

1.
See
Figure
3, for parts locations. Loosen the end cap lock using a 1.5 mm Allen
wrench.
2.
Remove the end cap cover from the terminal block end of the electronics housing.
3.
Feed loop power leads through one end of the conduit entrances on either side of
the electronics housing. The Remote Indicator accepts up to 16 AWG wire.
4.
Plug the unused conduit entrance with a conduit plug appropriate for the
environment.
5.
Torque terminal screws to 0.6 Nm (5.3 lbf.in) to 0.8 Nm (7.0 lbf.in).
6.
Connect the Loop Power wiring shield to earth ground only at the power supply
side.
7.
Replace the end cap and secure it in place being careful not to damage the wires.

RMA805 Enraf FlexLine Remote Indicator Quick Start Guide

Wiring the RMA805 Enraf FlexLine Remote Indicator

Overview
The Remote Indicator must be connected to the local HART compatible bus of the Enraf
Smartradar FlexLine or the Enraf SmartServo 954.
The Remote Indicator has 3 terminals. Following table provides the connection details:
Terminal
Description
1
Loop +
2
Loop -
3
Not used
The screw terminals are suitable for wirings up to 16AWG (1.3 mm
pair cable such as Belden 9318 or equivalent must be used for all wiring.
The cable shield must be connected at only one end of the cable. Connect it to the
FlexLine Gauge side and leave the shield insulated at the Remote Indicator side.
Note: If solid core wire is used strip insulation 1/4 in (6 mm). Once inserted under the
square washer the stripped portion should be contained under the square washer. If
multi-stranded wire is used, a ferrule is to be used and the stripped wire should be in the
insulated portion of the ferrule. The ferrule can be also be used on the solid core wire.

Electrical Wiring

The Remote Indicator shall be connected to the Loop + and Loop - terminals of the
FlexLine Gauge. Typically, these are terminals 24 and 25. See the installation manual of
the FlexLine Gauge for more information.
It is possible that other devices such as a VITO temperature convertor and a pressure
transmitter must be connected to the same loop. All devices must be wired in parallel.
Ensure all devices are set to 4 mA digital multi-drop mode before connecting to
the FlexLine Gauge. See Figure 4 for a connection diagram.

Explosion-Proof Conduit Seal

WARNING
When installed as explosion proof in a Division 1 Hazardous
Location, keep covers tight while the Remote Indicator is
energized. Disconnect power to the Remote Indicator in the non-
hazardous area prior to removing end caps for service.
When installed as non-incendive equipment in a Division 2
hazardous location, disconnect power to the Remote Indicator in
the non-hazardous area, or determine that the location is non-
hazardous before disconnecting or connecting the Remote
Indicator wires.
Remote Indicator installed as explosion proof in Class I, Division 1, Group A Hazardous
(classified) locations in accordance with ANSI/NFPA 70, the US National Electrical Code,
with ½ inch conduit do not require an explosion-proof seal for installation. If ¾ inch
conduit is used, a LISTED explosion proof seal must be installed in the conduit, within 18
inches (457.2 mm) of the Remote Indicator.
