1 General Information
The RAEGuard 2 PID is a fixed photoionization detector (PID) that
measures a broad range of volatile organic compounds (VOCs). It
operates on 10 to 28 VDC and provides an analog (4-20mA) three-
wire signal output, and RS-485 Modbus digital signal output.
RAEGuard 2 PID uses an intelligent processing platform and digital
sensor technology, supports multiple ranges and resolutions, and can
perform off-line calibration and environmental self-adaptation.
RAEGuard 2 PID has a graphic display and local sound alarm and
light status indicator. A magnetic key interface enables the detector to
be calibrated and operational parameters adjusted with the explosion-
proof enclosure in place. In addition, the PID module can be easily
removed in hazardous locations for calibration or maintenance.
Key features:
•Digital Smart Sensor Technology
•Three wires, supports 4-20mA analog output
•Operates in flow-through mode and can be used in most
environments
•RS-485 digital communication in ModBus protocol
•Explosion-proof stainless-steel enclosure for hazardous
environment applications
•Magnetic-key interface eliminates the need to open the explosion-
proof housing when adjusting parameters.
•Matrix LCD of 128x64 supports graphic display
•LED alarms when High or Low alarm point is reached
•Operation at 10 to 28 VDC
•Three dry contacts (<30V, 2A) normally open (or normally closed),
one for High and Low alarm, another for Fault alarm

2.2 Proper Product Disposal At End Of Life
The Waste Electrical and Electronic Equipment
(WEEE) directive (2012/19/EU) is intended to
promote recycling of electrical and electronic
equipment and their components at end of life. This
symbol (crossed-out wheeled bin) indicates
separate collection of waste electrical and electronic
equipment in the EU countries. This product may
contain one or more Nickel-metal hydride (NiMH),
Lithium-ion, or Alkaline batteries. Batteries must
be recycled or disposed of properly.
At the end of its life, this product must undergo separate
collection and recycling from general or household waste.
Please use the return and collection system available in your
country for the disposal of this product.

3 Operation
The calibration of all newly purchased Honeywell Analytics
instruments should be tested by exposing the sensor to a known
concentration calibration gas before the instrument is used or put into
service. Prior to factory shipment, the RAEGuard 2 PID is calibrated
and tested. However, the user should calibrate the instrument before
the first use.
Kit Accessories include: RAEGuard 2 Magnet Key, and User’s
Guide.

6 Installation and Access Instructions
6.1 Mounting
First, decide where the transmitter will be mounted. (Refer to
installation drawing, below.) Drill two holes in mounting surface,
with the center of the holes 5.25" (133mm) apart.
Besides directly mounting the RAEGuard 2 PID to a wall, it can be
mounted on a pipe.
WARNING
1. To prevent ignition of hazardous atmospheres, area must
be free of flammable vapors and supply circuit must be
disconnected before removing cover.
2. For European application, the installation must comply
with the requirements of EN 60079-14.

RAEGuard 2 PID User’s Guide
13
Note: When installing the RAEGuard 2 PID, make sure the sensor is
vertically oriented (pointing straight down). Also, make sure the
water-trap filter is connected to the gas inlet labeled “IN” (the longer
of the two inlets). Note: Only operate the RAEGuard 2 PID in a non-
condensing environment.

before unscrewing the
housing lid. Unscrew the
housing lid from the housing
body by rotating it counter-
clockwise. (As shipped, one
of the conduit holes is
covered by the provided hex-
head plug. The other conduit
is for wire connections.)
3.Tilt the instrument assembly
90˚.
4.
Unlock the 24-pin connector
on the ribbon cable.
5.
Lift the entire instrument
assembly out of the housing.
6.
Unscrew the sensor by
turning it counterclockwise.

To reassemble the instrument:
1Reconnect the 24-pin connector of the ribbon cable and lock it in
place.
2Fasten the cable to the board.
3Mate the board with the clip on the left side and tilt it over.
4Click the board into place.
5Screw on the sensor, making sure not to block the gas inlet hole
and connectors.
6Screw on the housing top.
7Screw down the fastening bolt.
6.3 Electrical Wiring
The detector connects to peripheral equipment via three terminal
blocks. These blocks accept 12AWG to 24AWG wire (0.2 to 4.0
mm2).

6.5 Earth Grounding Instructions
6.5.1 External Earth Grounding
Fasten the crimped ground wire with hardware as illustrated below.
The wire should have a minimum cross-section area of 4mm2for its
conductor.
6.5.2 Internal Earth Grounding
Use the same hardware as shown in the illustration of external earth
grounding. The wire should be no less than the size of the power lines.
Signal grounding can connect to a cable’s shielding layer if shielded
cable is used. If a separate wire is used for grounding, its cross section
should be greater than that of the power line.

6.5.3 Finished Grounding Wires
Internal and external grounding are shown here, as well as an
alternate external grounding point. Always follow local electrical
guidelines.
6.6 Alarm Contact Setup
The alarm contacts can drive external alarms such as a light or buzzer.
By default, the three relays are set for normally open (NO) operation,
meaning that contact is closed when in alarm.
You can separately change each relay from normally open to
normally closed (NC) operation by changing the position of the
jumpers on the internal printed circuit board.

Three jumper blocks are located below the three green terminal
blocks. They are labeled (from left to right): J4, J3, and J1. Here are
their functions:

Lift off the jumper for each one that you want to change and slide it
back on, either connecting the middle and top points or middle and
bottom points.
Important!
Once the system is operational, test the functionality of all three
relays.
Note: The relays may be disabled based on the sensor that is attached
to the RAEGuard 2 PID. Certain sensors, such as the 1-1000 ppm
DigiPID, disable the correction factor library and relays of the
RAEGuard 2 unit. Users who require these functions should use the
0.1-1000 ppm DigiPID sensor module.
