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

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 [-].

RAEGuard 2 PID User’s Guid e
You have two options:
• Press [-] to exit without making a change.
• Press [+] to go back to change the value.
Meas. Gas (Advanced Mode)
PIDs can be calibrated to a reference gas, yet display the
concentration readings in equivalent units of the target gas.
Isobutylene is typically used as the calibration gas because it is
inexpensive, readily available, has immediate sensitivity, and has very
low toxicity. Th e RAEGuard 2 PID can display concentrations of
over 200 gases using the built-in library of correction factors. PIDs
use a correction factor (CF) that converts the span gas con cen trat ion
(typically, isobutylene) to the measurement gas concentration.
Note: The measurement gas option 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 factors and relays
of the RAEGuard 2 unit. Users who require these functions should
use the 0.1-1000 ppm DigiPID sensor module.
Measurement gases are organized in two lists:
• Last Ten is a list of the last ten gases used by your instrument.
The list is built automatically and is only updated if the gas
selected from the Gas Library is not already in the Last Ten. This
ensures that there is no repetition.

Pump Duty (%) (Advanced Mode)
The pump’s duty cycle is the ratio of its on time to off time. The duty
cycle ranges from 30% to 70% (always on), and the default period is
10 seconds. Therefore, a duty cycle of 60% means that the pump is on
for 6 seconds and off for four seconds. The patented duty cycling is
employed by the instrument to clean the PID. A lower duty cycle has
a greater effect on keeping the PID clean than a higher duty cycle.
Important! Pump duty cycling is interrupted when the instrument
senses a gas. The pump’s duty cycle is disabled when the
measurement is greater than the low-alarm threshold and is re-enabled
when the reading falls below the low-alarm threshold. The alarm
threshold can be set, following the instructions on page 35.

20 Operating the Sensor Module
20.1 Preparing The Sensor For U se
Make sure the 8-pole input of the external intrinsically safe
equipment matches the interface connector pinout configuration of
the DigiPID. Make sure the input power supply range is between
4.75V and 5.25V DC, and the input current is about 200mA when the
sensor module is operated. The following mechanical drawing
includes the sensor module interface connector’s pinout. The Ex
entity parameter of the equipment connected to the DigiPID must fit
the entity parameters of DigiPID according to intrinsically safe fitting
rules.

RAEGuard 2 PID User’s Guid e
21 Using The Sensor Module
21.1 Gas Flow Routing Connection
The DigiPID has an “IN” and “OUT” port for sampling gas. Make
sure that the in and out sample tubes are properly oriented.
After making all gas connections and ensuring connection to the 8-pin
connector, turn on the power supply and warm up the sensor module.
Note: A two-hour warm-up time is recommended before making
critical measurements.
Firmly affix the sensor module to external equipment and make sure
the 8-pole interface connector makes a reliable, tight connection with
other equipment.
When you begin measurement, the sensor provides data to external
equipment, showing the current concentration of the specified gas.
Data is output digitally via the UART port or as an analog signal
(0.5V to 2.5V) from pin 3 of the interface connector. The sensor
module can be calibrated for different operations and gases.
If the DigiPID sensor is connected to Honeywell Analytics
equipment, you can affix the sensor module directly to the equipment
and then turn on the instrument’s power supply. The sensor module
runs normally. If the other external equipment is not a Honeywell
Analytics product, additional firmware and software support is
necessary. Honeywell Analytics can provide essential information
such as the handshaking protocol, port setting, flow rating, etc.
66
RAEGuard 2 PID User’s Guid e
21.2 Sensor Module Calibration
The sensor module is calibrated before it leaves the factory. However,
you can also calibrate the sensor module. Allow it to warm up for two
hours before calibrating it. Calibration should be performed using
external equipment, using a two-point calibration for the 100 and
1000 ppm VOC sensor.
100 ppm and 1000 ppm range sensor module calibration. First
perform a zero gas calibration by applying fresh air to the sensor
module. If the module is configured for use with a pump, the fresh
air’s flow rate must be greater than the pump’s draw rate. A
calibration time of 1 minute is recommended. The other calibration
point requires exposure of the sensor to span gas. The span gas
concentration should be 10 ppm and 100 ppm (for 100 ppm range) or
100 ppm and 1000 ppm (for 1000 ppm range) isobutylene, and
calibration time is also 1 minute.
IMPORTANT!
When changing the DigiPID’s Sensor Module, you can leave the
main power connected to the RAEGuard 2 PID. However, you must
enter the “Change Sensor” mode, following this procedure:
1. Hold the key over the “+” symbol for 3 seconds.
This screen appears, indicating that power to the DigiPID has
been removed:
67
RAEGuard 2 PID User’s Guid e
2. Replace the DigiPID Sensor Module.
3. When the new DigiPID Sensor Module is in place, tap
the key on the “-” (“Go”).
This restarts the RAEGuard 2 PID.
Note: Replacing the DigiPID Sensor Module and then restarting
the instrument resets all settings, including alarm levels, to their
original factory default values.

21.3 Maintenance A nd Calibration
The sensor module should be calibrated if it does not pass a bump
test, but no less than every 6 months, depending on use and exposure
to gas and contamination.
21.4 Replacing the Lamp And Filter
The sensor module is shipped with the lamp, sensor, and stainlessfilter installed. Periodically check the filter for dirt and contaminatio n,
which can impact the reading and response time.
Note: Always turn off power to the DigiPID before checking and
servicing any parts. After inspection and/or replacement of parts,
recalibrate th e instrument.
The lamp and sensor are not interchangeable with parts from other
manufacturers; use only Honeywell Analytics replacements. Use of
non-Honeywell Analytics components will void the warranty and
can compromise the safe performance of this product.

8. Slide a new Teflon UV Shield over the contact “legs,” and gently
press it down until it is snug against the surface of the Sensor
Module.
9. Use your fingers to screw on the four contact “legs.”
10. Use a soft, clean cloth to wipe any finger oils from the surface of
the contact “legs,” and set the Sensor Module aside.
11. Inspect the surface of the PID lamp. Clean it with isopropanol on
a swab, as outlined in the next section.
12. After the surface of the PID lamp dries, reassemble the unit.
73
RAEGuard 2 PID User’s Guid e
23 Sensor & Lamp Cleaning/Replacement
Clean the PID sensor module, the lamp and housing only if:
1. The reading is inaccurate even after calibration.
2. The reading is very sensitive to air moisture.
3. A liquid has been sucked into the unit and damaged the unit.
Use of the external filter helps to prevent contamination of the sensor.
To access the sensor components and lamp, gently unscrew the sensor
cover. Then hold the PID sensor and pull it straight out. A slight,
gentle rocking motion helps release the sensor.
23.1 Cleaning The PID Sensor
Place the entire PID Sensor Module into isopropanol. It is highly
recommended that an ultrasound bath to be used to clean the sensor
for at least 15 minutes. Then dry the sensor thoroughly. Never touch
the electrodes of the sensor by hand.
Also use an isopropanol-soaked cotton swab to wipe off the lamp
housing where it contacts the sensor when the sensor is installed.
Turn over the sensor so that the pins point up and the sensor cavity is
visible. Examine the sensor electrodes for any corrosion, damage, or
bending out of alignment. The metal sensor electrode “fingers”
should be flat and straight. If necessary, carefully bend the sensor
fingers to ensure that they do not touch the Teflon portions and that
they are parallel to each other. Make sure that the nuts on the sensor
pins are snug but not overtight. If the sensor is corroded or otherwise
damaged, it should be replaced.
74
RAEGuard 2 PID User’s Guid e
23.2 Cleaning The Lamp Hou sing Or Changing The Lamp
If the lamp does not turn on, the instrument will display an error
message to indicate replacement of the lamp may be required.
1. If the lamp is operational, clean the lamp window surface and the
lamp housing by wiping it with isopropanol using a cotton swab
using moderate pressure. After cleaning, hold the lamp up to the
light at an angle to detect any remaining film. Repeat the process
until the lamp window is clean. Never use water solutions to
clean the lamp. Dry the lamp and the lamp housing thoroughly
after cleaning.
CAUTION: Never touch the window surface with the fingers
or anything else that may leave a film. Never use acetone or
aqueous solutions.
2. If the lamp does not turn on, remove the lamp from the lamp
housing. Place the lamp O-ring onto the new lamp. Insert the new
lamp, avoiding contact with the flat window surface.
3. Reinstall the PID sensor module.
4. Tighten the sensor cover.
