Basic Operation

Button Usage

Operation of the detector is driven by a single button located on the front of the instrument

DVGHVFULEHGEHORZ:

xTurn On/Off

xMenu Navigation (Status and Options)

xLatched and Pump Alarm acknowledgement

xBacklight activation

Turning On the Detector

To activate the detector, press and hold down the button. If the battery is too low for

activationthe detector will display “LOW BAT” and then turn off again. Once activated, the

unit will begin to display gas readings immediately. Each sensor will show a chasing “O” for

the sensor reading while it is stabilizing and being self-tested

“Chasing O” Fully operational

Once all sensors have completed the warm up sequencethe detector is ready to detect

all gases.

Turning Off the Detector

Press and hold the button to start the shutdown sequence. The LCD will display OFF along

with a countdown. Release the button after the countdown and the unit will turn off.

Display Details

When a gas is reading at, or aboveits alarm thresholds, the gas identifier icon will flash

and the associated alarm condition icon will display.

The pump VWDWXVicon will be turned on whenever the pump is operating. During a

pump alarm (pump blocked), the pump status icon will flash with the warning icon.

During calibration or bump test, the calibration bottle will be displayed when it is time to

apply gas.

The battery is displayed in 3 barsas well asa percentage. The percentage calculation

is approximate and can be used to provide a rough estimation of the time remaining.

Warning: Users must familiarize themselves with the icons in both non-alarm and

alarm states.

Warning: If the display is missing icons or cannot be clearly read, discontinue use

and contact GCT.

Detector Maintenance

Pump Testing

Anytime that the gas tubing has been changed or reconnected to the detector, the sampling

system should be tested by blocking the end of the tube. When the gas flow is blocked, the

detector will go into alarm and disable the pump. Press the button to reactivate the pump.

Warning: Perform a blocked flow test before each day’s use

Warning: Perform a blocked flow test any time the sampling system is changed

Warning: Do not use silicon tubing with the catalytic bead LEL sensor.

Warning: Failure to detect a block may indicate a leak in the sampling system

Filter Replacement

The detector includes both a hydrophobic membrane filter and a particulate filter to keep

the internal pump and sensor areas free of water and debris. If these filters become

blocked, then the detector will be unable to continue sampling and the pump will enter into

a pump blocked alarm. Looking at the filter window will typically indicate a clean (white) or

dirty (dark color) condition.

If the filters require replacement, then remove the gas inlet by loosening the two screws.

Replace the hydrophobic and/or particulate filters as required, then reassemble to continue

operating the detector.

1 2 3

Applying Gas from a Gas Cylinder

The detector contains an internal pump that is continually drawing in gas through the gas

inlet. The best way to apply gas from a cylinder is through the use of a demand flow

(vacuum-actuated) regulator. This type of regulator will supply the exact amount of gas that

the detector is drawing with the pump. Alternatively, a pressure-based regulator rated for at

least 300 mO/min can be used. In that case, a T (or Y) fitting should be placed between the

regulator and the detector to vent the excess gas that exceeds the flow rate being sampled

by the detector’s pump.

Bump Testing

The detector can be configured to keep track of regular bump testing intervals. When the

detector has exceeded the bump interval, it will display “BUMP DUE” until it has been

successfully bump tested. To bump test the unit, either insert the detector into the MGC

Pump Dock, or manually apply gas from the bump test screen described below.

Manual Bump Test Instructions

To activate the manual bump test press the button twice rapidly to enter the user menu.

When the screen displays “Show Status” press the button once more.

The detector will flash between “BUMP DUE” and “APPLY GAS”. Apply gas to the detector’s

gas inlet. Once all sensors have gone into alarm, the unit will return to normal operation (in

alarm) and the bump due date will be reset.

If a bump test interval has not been programmed into the unit, users may simply apply gas

to the instrument during normal operation. However this will not be recognized as a bump

test by the detector and therefore it will be recorded into the event log as an event.

Calibration

7KH detector can be configured to keep track of regular calibration intervals. When the

detector has exceeded the calibration interval, it will display “CAL DUE” until it has been

successfully calibrated. To calibrate the detector, either insert the detector into the MGC

Pump Dock, or manually calibrate the detector as described below.

Manual Calibration Instructions

To enter calibration mode, manually press and hold the button down as in the turn off

sequence. Continue holding the button down until the CAL screen appears and finishes the

countdown.

MGC Pump User’s Manual

v1.02Portable gas detectors you can count on. RI

Once the screen displays “APPLY GAS”, apply gas to the detector’s gas inlet. As the detector

detects gas, the sensor readings will be displayed and adjusted throughout the calibration.

Once calibration is completethe detector will display the next calibration date before

returning to normal (alarming) operation. If a sensor fails to calibrate, the detector will

display an error for the failed sensor. Check your gas connections and concentration before

attempting a second calibration. If a sensor fails to calibrate after a second attempt, contact

GCT for either warranty replacement or replacement sensor(s).

Battery

The battery is displayed as both a percentage and a 3-bar battery icon. The percentage

calculation is approximate and can be used to provide a rough estimation of the time

remaining.

When the detector determines that only 20 minutes of run time remains, it will beep, flash

and display “LOW BAT” on the screen. This will repeat with 10 minutes remaining, and then

continuously for the last 5 minutes of run time. When the battery has expired, the detector

will give 5 long beeps and flashes, display “OFF” and then shut down.

To charge the detector, connect it to the provided charging adapter and plug it into an AC

outlet. The detector will cycle the battery icons in a charging fashion until the battery is fully

charged.

DO NOT charge the instrument in a combustible atmosphere.

DO NOT charge the instrument in temperatures above or below the specified range of 0°C to 40°C

DO NOT substitute any other battery type than specified and supplied by Gas Clip Technologies.
