Senko Sgt Disposable Personal Monitor User Manual

SGT Disposable Personal Monitor
User Manual

Product Overview

SGT is a portable single gas detector designed to detect the presence of oxygen, toxic and combustible gases in the ambient environment. When activated, SGT continuously monitors ambient air for the presence of a specific gas and alerts the user to potentially unsafe exposure with LED, vibrating, and audible alarms in the event that gas concentration exceeds alarm set points. And the alarm set point, calibration range, and display configuration can be changed via SENKO-IR Link (Optional).

WARNING

Any unauthorized attempt to repair or modify the product, or any other cause of damage beyond the range of the intended use, including damage by fire, lightning, or another hazard, voids the liability of the manufacturer.
Activate this product only if a sensor, visual, detection, and audible cover are clear from contaminants such as dirt and debris that could block the area where gas is to be detected.
Do not clean and rub the LCD screen of the products with a dry cloth or hands in a hazardous environment to prevent static electricity.
Perform cleaning and maintenance of the products in the fresh air that is free of hazardous gases
Test the response of a sensor regularly by the gas concentration exceeding the alarm set point.
Test LED, audio and vibration manually.
Gas concentration measurements by the sensor can vary based on the environment (temperature, pressure, and humidity). Therefore, calibration of SGT should be performed in the same (or similar) environment of the device’s actual use.
If the temperature changes sharply during the use of the device (e.g., indoors vs outdoors), the value of the measured gas concentration can suddenly change. Please use the SGT after the gas concentration value has stabilized.
Severe vibration or shock to the device may cause a sudden reading change. Please use SGT after the value of gas concentration has stabilized. Excessive shock to SGT can cause the device and/or sensor to malfunction.
All alarm value is set based on the alarm standard that is required by international standard.
Therefore, alarm values should be changed only under the responsibility and approval of the administration of the worksite where the instrument is used.
Use IR communications in the safety zone which is free of hazardous gases.
Do not attempt to replace the battery and sensor as SGT is designed to be disposable. Changing the battery and sensor may impair intrinsic safety and the attempt will void the warranty.

CAUTION
Before operating this device, please read the manual carefully.
This device is not a measurement device, but a gas detector.
If calibration and self-test fail continuously, please do not use the device.
For the O2 detector, perform calibration every 30 days in the fresh air environment.
Before use, please check the activation date, and if the activation date is passed, please do not use the device.
Clean detectors with a soft cloth and do not use chemical substances for cleaning.
To maintain 24 months lifetime, avoid the below activities except the necessary cases to check events(Max/Min), lifetime/concentration, and alarm setpoints. Otherwise, the frequent use of the button will deplete the battery life of fewer than 24 months.

1. Push the button frequently without valid reasons.
2. Frequent alarm operations or alarms remain for a long time. *Normal Alarm Use: 1 time and 2 minutes per day.
3. Connect with SGT IR Link frequently except for the bump testing.

In a safe environment, when pressing the button for 3 seconds, gas type and firmware version (ex. v2.2) will be displayed. For 10 seconds countdown, the device will be stabilized. After stabilization is completed, “V” icon will appear on the display screen and the device will move to Measure mode.

In the event that stabilization of the device fails,will appear on the display, and Measuring mode will not be entered. In this case, contact the authorized reseller or SENKO service center at 82-31-492-0445 for repair/return information.

< CAUTION >
Appropriate calibration of the device is required prior to operation. Always ensure that the device makes the proper detection response to the pertinent gas. Verify that debris that could interfere with the detection of gas is not blocking the area where gas is to be detected.

Mode

Measuring mode

• When activated, in Measuring mode, gas concentration or remaining life (Option) appears on the screen.
• Oxygen concentration is displayed in percent by volume (%Vol) and toxic concentration is displayed in parts per million. (PPM)

Display mode
In Measuring Mode, by pressing the button for one second, the following ICONs will appear in order.
Min (only for oxygen) -> Max -> CLR -> Remaining Lifetime(,,) -> 1st alarm set point ->

2nd alarm set point -> Firmware version -> Calibration Concentration
At the last step, if you press a button or do not push any button for a second, the device will return to Measuring Mode.

Alarms / Battery / Test Failure Display
When the gas concentration exceeds alarm setpointsor will be displayed and the device will vibrate, flash (LED), and beep. To remove alarms, move to a clean air location. and then a gas concentration will decrease, and the alarm will stop.

Alarm SetPoint

< CAUTION >
All alarm values are set based on the alarm standard that is required by international standards. Therefore, alarm values must be changed only under the responsibility and approval of the administration of the worksite where the instrument is used.

Event Log

The last 30 events are stored on a device. Once more than 30 events are stored, the log events are removed automatically in the order starting at Event 1. And, the stored log events data can be transferred to SENKO-IR LINK. Each alarm event records followings:
– Types of alarms (1st or 2nd) / Alarm concentration in ppm or % / Peak concentration

Calibration

< CAUTION >
Initial calibration is performed on all devices prior to shipment. Once received, calibration should be performed monthly (or quarterly) depending on the frequency of use.

Fresh Air Calibration
When pressing and holding the button for 5 seconds in the calibration mode(), an icon and ‘CAL’ mark will appear on the LCD.
And, press the button to initiate calibration for three seconds. When calibration begins, a countdown (starting at 10) will appear on the screen.
