D12 Features

LCD Graphics Display: Gas concentrations are displayed in large, easy to read numbers. The display also provides alarm indication and complete menus for setting up operating parameters. A backlight is available when operating in 3-wire mode.

Internal Data Logger: Measured gas values are stored at user definable intervals and can be recalled when needed on the LCD display. Data can be downloaded using the MODBUS™ interface.

Non-Intrusive Operation: Operating functions such as calibration, alarm setup, alarm reset, data view, and setup options are all available using a magnetic tool. It is not necessary to open the enclosure when making adjustments.

Password Protection: Program settings stored in the transmitter may be protected by a user selectable 4-digit password. Operators may still review all functions, but changes may only be made by authorized personnel.

Modular Electronics: The D12 electronic assembly plugs easily into the power supply board in the base of the enclosure. Transmitters can be removed for wiring and quickly replaced in the event of a fault condition.

Explosion Proof Enclosure: Transmitters are designed for operation in hazardous areas. The cast aluminum housing for the D12 transmitter is rated for Class 1, Division 1, Group B, C, D locations and is UL, FM, and CSA certified.

Scalable 4-20 mA: The output range for a particular sensor is programmable within the range boundaries set in that sensor.

Three Internal Alarm Relays: Optional relay outputs can be used for local alarm functions. All relays are programmable for set point, hysteresis, on-delay, off-delay, and other variables. Even a remote reset feature is provided for in the transmitter design.

Analog Output Simulation: Transmitter analog output can be set to user definable values. This provides for complete loop testing without the need to apply gas to the sensor.

Relay Output Simulation: Alarm relays may be activated on command to allow testing of local alarm devices. Any combination of relays may be activated based on operator selection. Output and alarms may also be inhibited for maintenance and calibration.

Serial Communication Interface: The transmitter is available with either HART™ or MODBUS™ protocol. The HART™ protocol supports the HART™ Universal and Common Practice Commands at 1200 baud using the Bell 202 FSK modem standard. The MODBUS™ protocol supports 9600 baud access to concentration and status information, and supports alarm setup and many other functions on either RS485 or RS232 (software selectable).

The D12 offers easy to use push buttons to scroll through the menus on the display.  Simply remove the cover by unscrewing off the enclosure.

 

D12 Summary

For many toxic and combustible gases, ATI offers a unique sensor response testing system unmatched by any competitive transmitter. Even outdoors in high wind conditions, the Auto-Test system provides reliable response checks to insure system integrity.  Sensor response is verified with an actual gas sample, generated on demand.  Generators store run time information accessible to operators, and are automatically tested for compatibility with the installed sensor.

D12 transmitters provide useful features that simplify installation, operation, and maintenance. From clear menu-driven setup pages to large numerical display of gas values, you simply can’t find a more versatile transmitter.  Gas concentrations are displayed in large, easy to read numbers. The display also provides alarm indication and complete menus for setting up operating parameters.  Backlighting is available when operating in 3-wire mode.

Operating functions such as calibration, alarm setup, alarm reset, data view, and setup options are all available using a magnetic tool. It is not necessary to open the enclosure when making adjustments.

ATI Specific Calibration Information

 

Auto-test Generator

The Auto-test option verifies the serviceability of the transmitter on a prescribed schedule by exposing the sensor to a small amount of gas, and verifying a minimum response. Three attempts per test are made, and if the sensor does not respond on the third attempt, a fault alarm is triggered (may be optionally disabled). 

D12 Auto-test generator

The test is performed at a specific time of day, and may be scheduled to repeat every 1 to 14 days. The date and time of the next test is available for editing, and the test may be triggered manually at any time, without affecting the preset schedule.

 

D12 Sensor holder

The Auto-Test Generator can be easily added to the standard Integral Sensor Holder.

 

The Auto-test option requires an E18 gas generator, which must be compatible with the installed sensor’s gas type, and full-scale range. Table below lists gas compatible generators and sensors.
