General Warnings and Cautions
WARNING!
1. The SM5000 Sampling Module - DC Pump Model described in this manual must be installed, operated, and maintained in strict accordance with the labels, cautions, warnings, instructions, and within the lim­itations stated.
2. An SM5000 Sampling Module - DC Pump Model is designed to sample gases or vapors in air. It cannot sample the concentration of gases or vapors in steam or condensing streams or inert or oxygen defi­cient atmospheres.
3. The unit must not be painted. If painting in an area where this unit is located, ensure that paint is not deposited on the module inlet fitting. Such paint deposits interfere with the sampling process and can result in improper readings.
4. Sensors are sealed units containing a corrosive electrolyte. Should a sensor develop leakage, immedi­ately remove it from service; then, remove it from its housin g assembly and discard it properly. Ensure that the electrolyte does not contact skin, eyes, clothing or circuitry; otherwise, personal injury (burns) and/or equipment damage may result.
5. Use only genuine MSA replacement parts when performing any maintenance procedures provided in this manual. Failure to do so may seriously impair instrument performance. Repair or alteration of the SM5000 Sampling Module - DC Pump Model, beyond the scope of these maintenance instructions or by anyone other than an authorized MSA service person, could cause the product to fail to perform as designed, and persons who rely on this product for their safety could sustain severe personal injury or death.
6. Properly vent the exhaust of this unit to a safe area. Improper venting of the exhaust can cause per­sonal injury or death.
7. Extremely high concentrations of combustible gas or vapor between t he lower explosive limit (LEL) and the upper explosive limit (UEL) will cause the indication on the SM5000 Gas Monitor to indicate full scale or above full scale. If the concentration level is further increased and exceeds the UEL, the dis­play will continue to show an above scale indication. Gas or vapor concentrations above the UEL are extremely dangerous since the instrument cannot measure them accurately, and when reduced by the addition of air to a level below the UEL, they again constitute a violently explosive mixture. Therefore, every alarm causing condition or situation must be investigated to determine that the area being moni­tored does not contain a gas or vapor in air mixture that exceeds the LEL or UEL.
Failure to follow the above warning can result in serious personal injury or death.
CAUTION!
1. Perform periodic leak check on all of this unit's flow system components and fittings. Ensure the flow is within specifications.
2. As with all sensors, high levels of, or long exposure to, certain compounds in the tested atmosphere contaminate the sensors. In atmospheres where an SM5000 Sampling Module - DC Pump Model may be exposed to such materials, calibration should be perfor med freq uently to e nsure that chann el opera­tion is dependable and display indications are accurate. Ensure the flow is checked to be with in spec ifi­cations.
3. The only absolute method to ensure the proper overall operation of this unit is to check the associated sensor(s) with a known concentration of the gas for which it has been calibrated. Consequently, calibra­tion checks must be included as part of the routine inspection of the system along with ensuring flow to be within specifications.
Failure to follow the above caution can result in injury, product damage, and/or an unsafe condition.

2 Installation
2.1 General
Install the Pump Sampling Module in the correct area classified in your facility . NOTE: The explosion-proof model hazardous area classification is Class I, Division 1, Groups A, B, C
and D. It is important that all local and national codes be followed when installing this model in a classified area.
Double check the area classification of the Pump Sampling Module. Refer to Fig. 3 to find the area classification label on your unit. Ensur e that the gas monitor being use d with
the sample pump is rated properly by referring to the gas monitor instruction manual for more details.
WARNING!
Do not mix units with diff erent area classifications. All units used in a classi fied area must have the proper area classification. Otherwise, an explosion hazard will exist, resulting in a possible explosion, injury or death.
The Pump Sampling Module for a general-purpose (GP) monitor can be a source of ignition. Install, locate and operate only in a non-hazardous area and in accordance with applicable codes.
If sampling from or exhausting into a separate location, the installation requires flashback arrestors at the inlet from a hazardous location and at the outlet to a hazardous lo cation, to prevent the prop agation of igni­tion of hazardous gases. Routinely check for pump system leaks that could create an explosive environment inside the enclosure.
Read and follow all instructions, warnings and cautions pertaining to this gas monitor. Failure to follow this warning can cause ignition of explosive environments resulting in serious personal
injury or death.
2.2 Mounting the Pump Sampling Module Unit (All Models)
(1) Locate the Pump Sampling Module and the gas monitor(s) in a clean, accessible location.
NOTE: Since the unit enclosure is non-corrosive, it can be mounted to the outside of a building or in other wet environments. Note the temperature and RH requirements.
NOTE: Use of Teflon tape or non-hardening thread sealant for environmental reasons is acceptable. NOTE: When installing multiple gas monitors, ensure all monitors have co nduit seals placed within the
requisite distances as outlined in their respective user manuals.
CAUTION!
Ensure that Pump Sampling Module or the gas monitor(s) display(s) are not blocke d or obscured. A blocked display will obscure the gas reading indication and sampling module indications. The unit must be mounted with the electrical input facing down and the label clearly readable.
(2) Mount the Pump Sampling Module and gas monitor(s):

2.4 Sample Line Placement
The Pump Sampling Module draws a gas sample to the internally mounted Ultima X, Ultima X5000, or S5000 Gas Monitor sensor.
The Pump Sampling Module can be mounted up to 100 feet (3 0 meters) away from the monitored area.
It uses 1/4-inch (6.35 mm) OD tubing to connect the Pump Sampling Module sample inlet to the end of
the sample line in the monitored area.
Tubing must be compatible with the sampled gas.
It takes a maximum of 30 seconds for the sample gas to reach the Pump Samp ling Module when 50 feet
(15.25 meters) of tubing is used:
To decrease this time, shorten the sample line length.
It is generally good practice to make the sample line as short as possible.
Depending on the gas characteristics, the end of the sampling tubing and the sample inlet should be
mounted to best optimize sampling of that particular gas. Consult your architect, facility manager or safety engineer for guidance in proper placement of the sampling tube inlet.
T esting for ventilation p atterns is useful in establishing sample inlet location. Smoke tubes (P/N458481)
are useful in measuring the direction and rate of air flow to determine which areas to monitor.
The particulate filter provided should be used at the sample end of the sample line to help prevent dirt
and dust from clogging the sample line. This filter must be compatible with the gas being sampled.
Alternative end of line filters are available if sampling from wet areas. If sampling from a hot and moist
area, use in line filter PN 637921. If sampling from an out door a rea where the sample lin e end is at risk for submerging under water, use in line filter PN 10015787. Both filters are purchased separately.
If installing in an area that is hosed-down or sanitized, use the water deflector accessory PN 10087383
for end of line sample, available for purchase separately.
It is recommended that a stainless steel of Teflon (Trademark of the DuPont Company) sample line be
used for monitoring gases that are highly reactive such as:
Nitrogen dioxide
Sulfur dioxide
•Chlorine
Chlorine dioxide
Hydrogen chloride
•Ammonia
Fluorine
•Bromine.
With the above gases, use filter (P/N 637921). The filter and sample line should be inspected periodically
and replaced if dirty.
CAUTION!
Do not attempt to clean the sample line by applying compressed air. All gas monitors must be mounted in ambient, interference-free air; otherwise, erroneous readings may
result.

2.6 Electrical Connection
A flow detector within the Pump Sampling Module activate s a relay when sufficient flow exists for proper gas detection. Generally, the Ultima X5000 transmitter analog output signal can be routed through the sampling module relay. When the flow is insufficient, the relay opens and the (AO) analog output signal is interrupted. Equipment monitoring the AO can be configured to sound an alarm when the signal is inter­rupted. See Fig. 5, Fig. 6 and Fig. 7 for a typical wiring schematic of the Sampling Module and Ultima X5000 Gas Monitor.
Other devices that alert when the flow loss relay activates can be connected to relay contact with the Pump Sampling Module.
NOTE: The Pump Sampling Module utilizes a shielded four-conductor wiring harness. It is recommended to use the shielded wire harness if installing the system where portable two-way radio, welding or large machinery are located.

Do not allow lid to remain off of the explosion-proo f Pump Sampling Module. Flammable or combustible ga s in the atmosphere may ignite a spark; that, in turn, may cause an explosion and result in injury or death.
(4) Wire the other end of the wiring cable to your read-out instrumen t and power supply , ensuring the cable
from the Pump Sampling Module is wired to the proper connections on the instrument. Consult the instrument instruction manual for more wiring details.
Tab. 4 Wiring identification
2.7 Initial Start-Up
Before starting up the Pump Sampling Module: (1) Check wiring connections (see Fig. 5 and Tab. 4). (2) Ensure that power supplied to the controlling instrument is the proper voltage with sufficient current
capacity to operate the instrument. Refer to the gas mo nit or instr uc tio n ma nu a l for pr op e r pow e r set-up.
(3) Apply power to the instrument through a remote circuit breaker.
CAUTION!
If relays in the controlling instrument are wired to external devices (e.g. horns, exhaust fans, and fire suppression systems), these devices may activate while adjustments are performed during the following procedures. Consult equipment instruction manual for further details. All instruments must be returned to normal operation when Pump Sampling Module and gas monitor adjustments are completed.
(4) Ensure the exhaust is not restricted. (5) The front panel low flow indication, red LED, should NOT be ON.
NOTE: If front panel low flow indication is ON, see chapter 4.3 "Troubleshooting Guidelines".

3 Calibration and Operation
3.1 Introduction
Calibration of the sensor when used with the Pump Sampling Module should follow the operating instruc­tions for the gas monitor used.
If this calibration procedure cannot be performed at any step, consult chapter 4.3 "Troubleshooting Guide­lines", localize the problem and replace the inoperative component.
MSA offers periodic service that is available on a contract basis; for more information, please call MSA at 1-800-MSA-INST.
3.2 Calibration Procedures
Place the instrument receiving the signal from the gas monitor into calibration mode, if applicable.
WARNING!
It is necessary to put the receiving instrument in calibration mode. If the instrument is not in calibration mode, any alarm relays may energize and activate any safety devices which are connected to the alarm relays of the instrument.
Equipment needed:
Ultima X (calibration kit #42) X5000/S5000 (CALKIT2)
Appropriate zero and span gas cylinders (see gas monitor instruction manual).
If using an Ultima X, Controller (P/N 809086) or an Ultima X Calibrator (P/N 809997). NOTE: If unsure of which span gas to use or of the span gas value, co nsult your safety engineer or officer
or facility manager.
(1) Locate the zero gas cylinder and the appropriate regulator and tubing. Screw the regulator into the
cylinder and connect the tubing to the regulator outlet. Ensure that tubing is compatible with the gas within the cylinder.
(2) Before initiating the calibration procedure s on the gas monitor, connect the tubing from the zero gas
cylinder to the calibration inlet (see Fig. 1).
3.2.1 Zeroing with the
Pump Sampling Module
(3) Initiate the calibration procedure on the gas monitor (see gas monitor instruction manual). (4) When the gas monitor indicates "APPLY ZERO GAS", press and hold the button by the calibration
inlet. Turn the knob on the regulator to permit the zero gas to flow . Simu ltaneously, the gas monitor will make all corrections to the zero signal; there are no adjustments necessary.
(5) When the gas monitor is done zeroing, close the cylinder valve, release the button by the calibration
inlet, and quickly rotate the zero gas cylinder to remove the zero gas cylin der. Do not remove th e tubing from the flow controller .
(6) Locate and screw regulator into the cylinder.
NOTE: If unsure of which span gas to use or of the span gas value, consult your safety engineer or officer or facility manager.

3.2.2 Spanning with the Pump Sampling Module
(7) When calibrating, the span immediately follows the zero (see gas monitor instruction manual). (8) When the gas monitor displays "APPL Y SP AN GAS", press and hold the button by the calibration inlet.
Turn the regulator knob to permit the span gas to flow. The gas monitor will make all corrections to its calibration; there are no adjustments necessary.
(9) When the gas monitor calibration is complete, release the button by the calibration inlet, close the
cylinder valve and remove the span gas cylinder. (10) Unscrew the regulator from the gas cylinder and replace all calibration components in the kit. (11) Return instrument receiving the signal from the gas monitor to normal run mode operation.
3.3 Operation
There are only two indicators on the front cover of the Pump Sampling Module which af fect the operation of the unit.
The NORMAL indicator, the green LED, shows that there is power to the unit and the flow is greater than
.5 LPM.
The LOW FLOW indicator, the red LED, indicates that the flow detector has insufficient gas flow for
proper monitoring. See chapter 4.3 "Troubleshooting Guidelines" for corrective action.
WARNING!
The pressure switch can fail and the orifice can clog if water enters the system. Always use the proper in­line filter (P/N 10051406).

4 Maintenance and Troubleshooting Guidelines
4.1 Maintenance
The Pump Sampling Module requires minimal maintenance. However, the filters need routine inspection and possible replacement. It is good practice to have on hand replacement filters to minimize any down time of your unit (see Tab. 6).
4.2 Filter Maintenance
Filter maintenance consists of visual inspection of the two filters, end-of-line filter and in-line filter. When new, filters are white or slightly yellowed; when loaded with dust or dirt, they normally turn dark in color . V isu­ally inspect the two filters periodically. The frequency of this inspection depends on the environment; if your environment is extremely dirty or dusty , this inspection should be done often.The in-line filter is hydrophobic and will not pass liquids.
End-of-line filters must be located so that they are not exposed to liquids or steam. If liquids become entrapped within a filter, replace the filter as it will interfere with proper operation of the unit.
