Special Conditions for Safe Use

In potentially hazardous areas the G400 MP-2 pump must be used properly with a G450 gas detector, it must be carried with you and must not be laid down unattended (to prevent electrostatic charge).

The pump must be attached to the G450 gas detector before entering a potentially hazardous area. It must not be disconnected from the detector in the hazardous area. The G400 MP-2 pump is only approved when attached to the model G450 multi-gas detector.

The G400 MP-2 pump utilizes a magnet for on/off operation of the pump.

Use caution when operating the pump around magnets or in areas of high magnetic fields, as this may affect the operation of the pump. Do not operate in close proximity to magnets.

Always pay attention to the ignition protection and the temperature class of the gas detector.

1. MSHA approved for use with any of the following battery packs:

P/N 1450-202, P/N 1450-211, or P/N 1450-212. These battery packs may only be changed in fresh air only.

2. Battery packs P/N 1450-211 and P/N 1450-212 may only be charged in fresh-air locations.

3. Battery pack P/N 1450-202 cells may only be replaced with two

Duracell MN1500 LR6 “AA” batteries. Both cells are to be replaced at the same time with identical part number cells. P/N

1450-202 must include the alkaline battery cover plate (P/N 1403-

202).

4. The Model G400 MP-2 is only approved for use when attached to the Model G450 Multi-Gas Detector.

5. The Model G400 MP-2 is not to be operated in close proximity to magnets.

General Description and Design

The G400 MP-2 pump is a very small and convenient supplemental module for the G450 gas detector. It allows gas sampling from a safe distance, without exposing the user to hazardous atmospheres. The pump has its own power supply, which works independently from that of the G450 monitor.

Sampling Inlet

The sampling inlet is on the bottom of the pump body.

Here you can attach accessories for taking gas samples (hose adapter with sampling line, probe, GfG telescopic probe).

Connecting the Pump

Sampling inlet

Connection for gas sampling accessories

Attach the G400 MP-2 pump to the G450 gas detector and secure it with the thumbscrews.

For permanent attachment to the G450 gas detector you can attach the pump with 2 additional screws (included). You will find the mounting holes for the additional screws under the blue sensor cover. To access the holes, remove the Phillips screws from the side, slide the sensor cover upwards – push the lock smoothly with a screw driver – and remove it.

Once the screws are in place, replace the sensor cover, slide it downwards and replace side screws.

To remove the pump from the G450 monitor, remove all attached screws.

Operational Hints

NOTE!

If the blue sensor cover is slid upwards forcefully with the two

Phillips screws removed, it may slip over its lock and the diffusion inlets will not be properly covered. This may result in false detection, since ambient air could dilute the concentration of the gas sample. Make sure, therefore, that the diffusion inlets are closed properly if the screws have been removed.

Turning the Pump On

Slide the blue sensor cover upwards to turn the pump on. With sufficient battery capacity the pump motor starts after a short delay (approximately

1 second). The battery capacity is indicated on the instruments display.

The proper operation of the pump is indicated by an icon on the display.

Turning the Pump Off

Slide the blue sensor cover downwards to turn the pump off. The pump should be turned off after detection to prevent unnecessary use of the batteries.

Remote Sampling

The pump is designed to draw at a rate of 1 foot per second (1 meter per

3 seconds). Allow enough time for the sample to be drawn through the entire length of sample tubing and probe, plus enough time for the readings to stabilize (at least another 20 seconds). Always test the space at different levels as gases may stratify depending on weight. It is recommended that the space be tested at incremental levels of 3 feet or 1 meter.

Each time a new level is to be tested, allow enough time for the sample to propagate through the entire length of the sampling system, plus enough time for the sensors to stabilize (at least another 20 seconds).

Pump Fault

If the sampled gas amount is too low (<0.25 l / min) or if the power supply to the pump motor is interrupted, the instrument’s display flashes an alarm.

A pump fault may be caused by a restricted flow in the tubing or sample probe. Make sure that any restriction is eliminated from the tubing and sample probe; this may include a need to replace the in-line filter.

ATTENTION: During a low flow alarm, proper detection in connection with the G450 monitor cannot be assured.

Power Supply

The G400 MP-2 pump is powered by an alkaline or NiMH battery module.

The power supply module allows continuous operation for up to 10 hours.

The operational time may be reduced, however, by a high load on the pump motor (e.g. bent sampling line / blocked filter). The Pump is only approved with P/N’s: 1450-202, 1450-211, or 1450-212 battery packs.

The G400 MP-2 pump turns off automatically if the battery voltage falls below the minimum level needed for proper functioning. At least 15 minutes before automatic deactivation, the display icon flashes once per minute to indicate insufficient battery voltage.

Battery Replacement

WARNING: The pump must not be opened in explosion endangered areas. Replace the battery module in fresh air only, and is

MSHA approved for use with any of the following battery packs: P/N 1450-202, P/N 1450-211, or P/N 1450-212. These battery packs may only be changed in fresh air only.

Always turn the pump off before replacing the battery module.

Check for the correct polarity of the new 1.5 V AA alkaline batteries (as shown below). With incorrect polarity the pump will not turn on.

Battery pack P/N 1450-202 cells may only be replaced with two

DURACELL MN1500 LR6 “AA” batteries .

WARNING: Both cells are to be replaced at the same time with identical part number cells. P/N 1450-202 must include the alkaline battery cover plate (P/N 1403-202), to prevent power interruption if the detector is dropped or jarred.

• Battery can only be replaced in fresh-air locations

Tighten all screws after inserting the battery tray.

Test Battery Capacity

Once the pump is turned on, the battery capacity is automatically indicated on the instruments display. To activate the battery test, turn the pump on (slide the blue sensor cover upwards).

System Fault

The circuitry of the G400 MP-2 pump is continuously monitored. If a fault is recognized, an instrument alarm is triggered.

To correct this problem, replace the batteries. If the fault still exists, return the unit to the manufacturer.

Charging

CAUTION : Battery packs: P/N 1450-211 and P/N 1450-212 may only

be charged in fresh-air locations, using the G450 cradle

charger.

Appendix

Cleaning

Give the G400 MP-2 pump a short visual check after use. Use a damp cloth to remove stains or dirt from the casing. Never use solvents or cleaning agents!

Changing the Filter

To change the filter, separate the pump from the G450 monitor and slide the blue cover down. Use tweezers to remove the filter and replace it with a new one.

Inspection Filter

In addition to regular maintenance, the user has to do the following checks at least before every shift:

• Visual check for damage

• Check battery capacity

• Check sampling performance

Maintenance and Regular Function Check

Depending on application conditions and technical requirements, maintenance should be done in intervals required by the application. Maintenance includes measures which retain the operational status of the G400 MP-2 pump.

• Visual check for damages

• Check filter condition

• Check pump battery capacity

• Check sampling performance

• Check low flow alarm

In addition to the above, we recommend getting the pump checked for proper functioning by an expert in combination with the (at least) annual inspection of the G450 monitor.
