Mounting Remote Indicator

Summary

Remote Indicator models can be attached to a two-inch (50 millimeter) vertical or horizontal pipe using Honeywell’s optional pipe mounting bracket. Honeywell’s optional wall mounting bracket is also shown below. Figure 1 shows typical bracket-mounted installations.

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 the 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

1. 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.
2. 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).

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. The following table provides the connection details:

• The screw terminals are suitable for wiring up to 16AWG (1.3 mm2). Shielded twisted 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 a 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 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 converter 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.

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.

Explosion-Proof Conduit Seal

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, does 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.

Jumper Settings

On the Remote Indicator, there is a failsafe jumper and a write-protect jumper behind the display on the Communication Module. The top jumper is the failsafe jumper. It is highly recommended to put the failsafe jumper to DOWN (Downscale). The bottom jumper sets the write protect.

Configuration Guide

The Remote Indicator 3-button interface provides user interface and operation capability without opening the Remote Indicator. The user must pressthe button to call up the Main Menu. To exit the Main Menu and return to the PV display screen, select <EXIT>. Use the button to scroll through the list of menu items. Press the button to select an item for data entry or activation. When an item is selected for data entry or activation, the cursor is positioned over the left-most digit to allow editing of the value. No action is taken against a menu item until the button is pressed.

• Consult the manufacturer for dimensional information on the flameproof joints for repair.
• The painted surface of the RMA 800 series may store electrostatic charge and become a source of ignition in applications with a low relative humidity of less than approximately 30% relative humidity, where the painted surface is relatively free of surface contamination such as dirt, dust, or oil. Cleaning of the painted surface should only be done with a damp cloth.
• The ambient temperature range and applicable temperature class of the equipment are as follows: RMA805 series: T4 for -50˚C < Ta < 70˚C
• The RMA800 series enclosure contains aluminum and is considered to present a potential risk of ignition by impact or friction. Care must be considered during installation and use to prevent impact or friction to avoid impact.
• If a charge-generating mechanism is present, the exposed metallic part on the enclosure is capable of storing a level of electrostatic charge that could become incendiary for IIC gases. Therefore, the user/installer shall implement precautions to prevent the buildup of electrostatic charge, e.g,. earthing the metallic part. This is particularly important if the equipment is installed in a zone 0 location.
• On installation, the RMA800 series shall be provided with supply transient protection external to the apparatus such that the voltage at the supply terminals of the RMA800 series does not exceed 140% of the voltage rating of the equipment. However, when an RMA805 is connected to a SmartRadar FlexLine or to a SmartServo 954, the supply transient protection is included in the SmartRadar FlexLine or SmartServo 954.
