NOTES:

1. Battery backup time depends on run mode and frequency of transmission.

2. Limited by lithium iron phosphate charging temperature. Lower temperature operation will require

external or internal heating to maintain sufcient battery temperature for charge acceptance. Contact

the manufacturer for more information.

3. Requires SIM card and suitable data plan on AT&T or T-mobile.

4. Cloud based analytics can be developed with additional contract.

5. Solar panels used with the SPOD must be NRTL certied to UL121201, Class I, Division 2, Groups A,

B, C, and D T3C, and must be wired in using a method that is acceptable for use in a Class I, Div. 2

area per the NEC (National Electrical Code) and CEC (Canadian Electrical Code). The recommended

panel is SENSIT Part Number 360-00769 (Solarland SLP-030-12C1D2 – CSA File Number 2721637).

6. SPOD can be plugged into an alternative power supply; the power supply must be suitably limited to

ensure the peak open circuit voltage cannot exceed 24 volts and the peak short circuit current cannot

exceed 620mA.

CONNECTION INFORMATION

The SPOD C1D2 only has a single connection port, located at the bottom of the unit, next to the sensor.

This connection is for charging and direct data communications to the SPOD C1D2 unit. The port only

takes connectors in the Phoenix Contact SAC-HZ-5P family of products (UL File E359524). When the port

is in use, the retained locking clip must be used with the connection to prevent accidental disconnection.

All connections must be wired using a method that is acceptable for use in a Class I, Div. 2 area per the

NEC (National Electrical Code) and CEC (Canadian Electrical Code).

SENSOR INFORMATION

⚠EXPLOSION HAZARD – ONLY SENSOR PART NUMBER 375-PID1BIXF-01

(ION SCIENCE MP3SBLBXBU2) AND 375-PID1BIHS-01 (ION SCIENCE

MP3SHLHSBU2) CAN BE USED WITH 937-00000-20 AND 937-00000-21,

RESPECTIVELY.

OVERVIEW PARAMETER

Default PID Detection Range 0.1– 30 ppm1for normal version (937-00000-20)

10 ppb – 2 ppm1for high sensitivity (937-00000-21)

Default PID Lamp Energy 10.6 eV2

Target PID Accuracy +/- 20 ppb min or 10%3,4

Response Time 5-10 seconds5,6

Expected Lamp Life 1 year+

NOTES:

1. VOC range reference to isobutylene.

2. Factory calibration conducted with 1ppm isobutylene and ultra zero air. This value is a target and

cannot be guaranteed for all environments.

3. PID Sensors are sensitive to high amounts of humidity and may rail at the upper output if humidity is

excessive. The SPOD contains an internal sensor heater to minimize humidity interference.

4. If the unit has been off for an extended period, it could take several minutes to an hour for the PID

readings to drop to normal operating condition depending on storage conditions. This stabilization

may temporarily interfere with VOC detection.

5. Exposure to very high levels of VOCs may saturate the detector for several minutes to an hour.

DEPLOYMENT GUIDE

Unpack the sensor unit and check for any physical damage or obstructions at the sensor openings.

1). Power on unit. The illuminated switch should turn on and begin ashing blue. After initialization the

LED will turn green and periodically ash blue or red once per second indicating normal operation.

This is to perform a check of the unit before mounting and deployment.

2). Verify the absence of sensor errors with illuminated switch. If the switch is ashing only red or yellow

an error occurs. For more information on the errors indicated by the illuminated switch, see “SPOD

Firmware and Troubleshooting Guide”

3). Turn off the unit.

4). (OPTIONAL) Connect the solar panel to the power port on the SPOD, left and down of the sensor

opening when the SPOD is placed with the front face (containing the serial number) facing up to-

wards the sky.

⚠ EXPLOSION HAZARD – DO NOT CONNECT OR DISCONNECT THE CABLES

TO THE SPOD C1D2 UNLESS IN A NON-FLAMMABLE AREA, AND WHEN

THE INSTRUMENT IS SHUT OFF (I.E., NO LIGHT CAN BE SEEN FROM THE LED

ON THE SWITCH)

5). Move the unit to the location to be deployed, and mount to hardware present at the location or a

tripod. Make sure the unit after mounting can withstand the environmental conditions at the location

(i.e., heavy winds).

⚠ EXPLOSION HAZARD – MUST BE DEPLOYED IN AN UPRIGHT

CONFIGURATION (SENSOR POINTING TO THE GROUND)

6). Power on unit. The illuminated switch should turn on and begin ashing blue during initialization.

After initialization the LED will turn green and periodically ash blue or red once per second indicat-

ing normal operation.

SENSOR REPLACEMENT

⚠EXPLOSION HAZARD – PID SENSOR REPLACEMENT SHOULD BE COMPLETED

IN A NON-FLAMMABLE, CLEAN, AND DRY ENVIRONMENT.

1). Make sure the SPOD is not powered on (i.e., there is no light coming from the LED on the switch)

2). Loosen the sensor cap retaining set screw ½ turn counterclockwise using a 3/32” hex key wrench.

3). Unscrew the sensor cap assembly counterclockwise by hand until it can be removed from aluminum

sensor holder base.

4). Grasp the protective sensor membrane holder and pull out to remove.

NOTE: The PID sensor may come out with the protective sensor membrane holder, or it may remain

in the PID socket

5). Remove the sensor from the 3 pin PID socket or remove it from the sensor membrane holder.

6). Install new PID of type 375-PID1BIXF-01 (ION SCIENCE MP3SBLBXBU2) OR 375-PID1BIHS-01 (ION

SCIENCE MP3SHLHSBU2) only into the 3-pin socket. The sensor can only be installed in one orien-

tation.

7). Reinstall the protective sensor membrane holder on the aluminum sensor holder making certain the

PID goes inside the closed cell foam tube. Securely press the membrane holder into the conical taper

of the aluminum sensor holder. It may not seat completely but that is okay.

NOTE: Prior to reinstalling protective sensor membrane holder, ensure that foam tube seal is pressed

securely against the sensor membrane. This minimizes any excess head space above the sensor that

will slow the sensor response and recovery time.

8). Reinstall the sensor cap assembly making certain the stainless-steel mesh is fully seated into the sen-

sor cap. The sensor cap should be tightened by hand until it stops rotating. At that point it should be

backed off ¼ turn and retightened again until it stops rotating. This retightening step will fully seat

the membrane holder and ensure the cap is fully tightened.

9). Tighten the sensor cap retaining screw to 0.5 Nm using a 3/32” heck key wrench. Ensure that the

sensor cap is secure and cannot be loosened by hand.

10). Turn the SPOD on and verify PID operation and calibration. Ideally, a bump test would be performed

on the PID to ensure sensitivity.
