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) threewire 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 detecto r to
be calibrated and operational parameters adjusted with the explosionproof 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

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

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.
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.

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.

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.

7 Display And User Interface
7.1 User Interface
The RAEGuard 2 PID’s user interface consists of a status LED, an
LCD display, and three keys, [+], [MODE], and [-]. The three keys
are operated by using the Magnet Key.
RAEGuard 2 PID user interface.
7.2 Magnet Key
The RAEGuard 2 PID has no external switches, but instead uses the
magnetic end of the RAEGuard Magnet Key (p/n 033-3032-000) to
activate switches built into the unit.

7.3 Using The Magnet Key
Using the magnet end of the Magnet Key, briefly touch the glass
above the MODE circle or the triangles labeled [+] and [-]. Then
remove the key straight out and away from the RAEGuard 2 PID.

Important! Never drag the key sideways, or two functions may be
activated.
7.4 System Initialization
When the RAEGuard 2 PID’s system power is turned on, it initializes
and a Honeywell logo appears on the display. As the transmitter is
warming up, each component is checked. The countdown timer
appears on the screen for the warm-up.
7.5 Reading Display
As the transmitter enters the Reading Display, it automatically starts
testing for errors and goes through a cycle of checking each alarm
condition. If there are no errors or alarm conditions, the green “OK”
LED is lit and the gas concentration is displayed.

7.6 Instrument Status Display
After warm-up, the detector enters the Status Display. It automatically
starts testing for errors and goes through a cycle of checking each
alarm condition. If there is no error message or alarm condition, gas
concentration is displayed and LED flashes green.
If there is an error or alarm, a corresponding message shows on the
screen, and the LED indicates different statuses:

and perform a test of the Analog system without entering P rogramm ing
Mode.
At the main reading screen, hold the magnetic key over [-] for two
seconds. The RAEGuard 2 screen changes to show the current peak
value in memory:
• If you do not want to clear the peak value, press [-].
• To clear the peak value (reset it), press [+].

Press [-] to advance to the Analog Output Test screen.
The analog output test is primarily used when commissioning a
system. It ensures that the mA output at the sensor location is the
same as the input received on the system controller. Run the analog
test to make sure that the readings on the detector match the readings
on the controller.
26
RAEGuard 2 PID User’s Guid e
The analog test uses a timed step function to output specific mA
values in sequence. The test starts at 4 mA, which typic al ly
corresponds to 0 ppm output. The analog test then progresses in
increments of 2 mA (4, 6, 8, etc., all the way up to 20mA). The
corresponding sensor reading in ppm is shown on the unit’s LCD
display.
For example, if you have a sensor range of 0 to 1000 ppm, the
detector LCD displays in sequence 0, 125, 250, 375…all the way up
to 1000 ppm. These are the ppm equivalent values of 4,6, 8, 10, etc.,
all the way up to 20mA.
Note: You can stop the test and exit at any time by pressing [-].
