Safety precautions for the SDT200 ATEX version

Please read carefully the safety precautions before using the SDT200 – ATEX version in a potentially explosive environment.

• Make sure your SDT200A protection class is suited regarding the environment it will be used.
• Under no circumstances, do not attempt to service or replace SDT200 ATEX version components. In case of malfunction, contact SDT  International or SDT local  representative.
• Maintenance must always be performed outside potentially explosive environments.
• Battery charge must exclusively be performed outside potentially explosive environments.
• FUBATTR270-02 is the only authorized power source for SDT200 ATEX version.
• The max. permissible room temperature is:
  • -15°C to 48°C for T3.
  • -15°C to 60°C for T2.
• Potential danger of static electricity for the display. Avoid electrostatic charge:
  • Avoid friction.
  • No dry cleaning.
• Do not use USB connectivity in dangerous area.
• Do not use SDT carrying case in dangerous area

Getting Started

4.1. Charging the battery
The SDT200 uses an internal NiMH battery. The battery charger outlet will connect to a socket on the bottom side of the SDT200.
Charging the battery of the SDT200 ATEX version must exclusively be performed outside potentially explosive environments.
Due to the typical self-discharge rate of NiMH batteries, it is recommended to charge the SDT200 battery at least every 3 months, even if it is not used.
It is recommended not to store the SDT200 with an uncharged battery for more than a few weeks. This would significantly reduce the battery life span.
Only use the charger provided by SDT.
The charging time will typically be 6 hours. When the LED of the charger is continuously green, the SDT200 battery is completely charged.
Like most batteries these days, leaving the SDT200 charging after the charger says it is charged does not hurt the battery – in fact it very slowly tops the charge up a little  more.
You can charge the SDT200 switched off. You can also trickle charge the SDT200 switched on, so you can be using it to load and unload data, for example, and charge it at the same time.

A fully charged battery will give you about 8 hours of continuous use. This will vary of course depending upon your need to use the backlight and the power drain of certain  external sensors that you might be using.
You can increase the autonomy by adjusting the Auto Power Down and the time before switching off the backlight.
For a device that has been discharged for several days/weeks or in case of a problem encountered during charging, follow the procedure below to force a full charge cycle:

1. Connect the device to the charger;
2. Do a “RESET” by pushing the switch with a paper clip in the small hole above the audio output (see red circle in the “rear side” picture above);
3. Wait at least 4 hours for a full charge before turning the device on again. The green LED should be lit continuously.

When a charge cycle is complete, the counter available in the System Info/Battery Info menu is incremented by +1.

Please note that the device must be turned off to charge the battery.
• When the device is turned on, the charger supplies power directly to the device without charging the battery.
Before storing the device for a long period of time, it is recommended to fully charge the battery.
• There is no specific battery for the “real time clock”, and it is powered by the battery pack.

4.2. Turning on & turning off the SDT200
To turn on:
Press the Power button on the bottom right of the keypad. The status LED will shine dark blue. Then, a few seconds later you will see on the screen the SDT logo and the  message “loading”. If you do not see this display your battery might be flat.
To turn off:
Push the Power button on the bottom right of the keypad. You will see the following display:

Confirm the device shut down by pressing the Enter button.

4.3. Plug & unplug an external sensor
The SDT200 is equipped with a LEMO connector, used to plug external sensors.
It is a commonly used industrial connector, considered for its reliability and robustness. It has a sprung-loaded knurled barrel and mechanical polarization to go only in one way round.

To plug a LEMO connector:

• Line up the red dot on the plug with the red mark on the connector.
• Insert the plug into the connector without any rotating movement.
  When an external sensor is connected to the SDT200, it is automatically selected. However, you can switch between available sensors using the F1 button.

To unplug the LEMO connector

• Move up, towards the cable, the ring located on the bottom of the plug.
• Only pull the connector without any rotation.
  Please, never pull on the cable itself.

Miscellaneous

7.1. Recommended calibration intervals
SDT recommends annual recalibration of SDT instruments and annual verification of sensors. This periodicity is coherent with the observed long-term stability of SDT  electronic equipment’s.
However

• For new equipment leaving the factory the initial period is extended to 15 months instead of 12 (to avoid any possible discrimination between users due to transportation time, customs clearance, etc.).
• SDT recognizes that each customer may have their own Quality Assurance Standards and internal requirements. If a customer has established a Quality Assurance  Program that includes a documented procedure for measurement deviations, and if an instrument and the relevant sensor show acceptable deviations and do not show  signs of physical damage, then calibration periodicity could be extended to two years.
• Third party organizations having more authority (Class, or State Administrations) may have defined their own regulations for example 6 months, or 2 years calibration  interval: by evidence, local legally applicable regulations supersede SDT rules.

For these reasons, SDT Calibration Certificates do no more mention a “calibration due date”, but simply the “last calibration date”.
For user convenience, the date of the last calibration of an SDT200 or 270 instruments can also be found in the menu screens.
This text refers to SDT document DC.QUAL.005.

7.2. EU directives and Standards
SDT200 Multifunction Detector (standard FUR200 and ATEX version FUR200A) has been designed and tested to meet the following directives and standards. The declaration of CE conformity is available on SDT website at https://sdtultrasound.com/support/downloads/certificates/
This product meets the following essential requirements of the applicable European Directives:

• 2014/30/EU; Electromagnetic Compatibility Directive (EMC);

• 2014/34/EU; Equipment and protective systems intended for use in potentially explosive atmospheres (ATEX) (applied to FUR200A).

EC type examination certificate nR ISSeP11ATEX008X delivered by ISSP, notified Body nR 0492
ATEX type examination certificate of conformity nR 20/BE/4608-0 in accordance with Annex IV-Module D “Quality Assurance of the Production Process” delivered by  APRAGAZ notified Body Nr 0029

The equipment hence displays the CE logo of being compliant to the current regulations.
