  • Page 30: Bump-Testing

    Series D12 LEL Gas Transmitter with Catalytic Bead Sensor Bump-Testing “Bump-testing” refers to a test whereby the sensor is briefly exposed to gas in order to verify the reading moves upscale from zero. It is recommended that it be performed at least once a month, using a small amount of bottled span gas.

  • Page 31: Calibration

    Series D12 LEL Gas Transmitter with Catalytic Bead Sensor Calibration Calibration Frequency While the D12 transmitter requires no periodic calibration, Combustible sensors should be zero and span calibrated every 3-6 months. The frequency of calibration may depend on environment factors. Sensors frequently exposed to dirt, oil mist, vapors, or very dry air, may require more frequent calibration.

  • Page 32: Zero Calibration Procedure

    Series D12 LEL Gas Transmitter with Catalytic Bead Sensor Zero Calibration Procedure Performing a zero calibration requires a cylinder of Zero-Air with a 500 cc/min regulator, calibration adapter, and a convenient length of ¼” D12 GAS Transmitter tubing.

  • Page 34: Spanning For Otm Gases (Other Than Methane)

    Series D12 LEL Gas Transmitter with Catalytic Bead Sensor Spanning for OTM Gases (Other Than Methane) Because the combustible gas sensor is normally calibrated for Methane, differences in the LEL and oxidation rates of other gases may lead to reading errors. These errors may be corrected by recalibrating the sensor span.

  • Page 35: Sensor Calibration Records

    Series D12 LEL Gas Transmitter with Catalytic Bead Sensor Sensor Calibration Records A calibration record is written into the sensor memory each time a zero or span calibration is performed, and when a calibration Undo is performed. Enough memory is reserved for 63 zero calibrations and 63 span calibrations.

    Series D12 LEL Gas Transmitter with Catalytic Bead Sensor Alarm Relays The D12 transmitter provides three optional SPDT mechanical relays rated for 5 amps, non-inductive loads at 250VAC. These relays are suitable for switching small loads, such as horns and warning lights, but should not be used to switch motors or other high current, inductive loads.

  • Page 50: Relay Setup Page

    Series D12 LEL Gas Transmitter with Catalytic Bead Sensor Relay Setup Page Relays are configured in the Relays Setup page, which is accessed by selecting Menu, Setup, Alarms, and (Relays) Setup.

  • Page 51: Inhibiting Alarms

    Series D12 LEL Gas Transmitter with Catalytic Bead Sensor Inhibiting Alarms Alarms should be inhibited to prevent false activation, such as done just prior to “bump-testing” the sensor. The most convenient method for temporarily inhibiting alarms is from the Main Display. Hold the magnet over the ESC key for 2 seconds, and remove it.

  • Page 52: M A Output

    Series D12 LEL Gas Transmitter with Catalytic Bead Sensor 4-20mA Output The 4-20mA output normally sources positive current to a receiver, proportional to the main 4-20mA Output reading. The output is 4 mA at zero, and rises to 20mA at the full-scale range (see “Range” variable in Sensor Setup Page), and may go as high as 24mA (125%LEL) in case of gas flooding.

  • Page 62: Ascii

    Series D12 LEL Gas Transmitter with Catalytic Bead Sensor Protocol specific settings are configured on separate pages that are accessible from links on the Setup page, and are discussed below. ASCII ASCII is used for sending the data log to a serial printer, terminal, or terminal program, using RS232 (RS485 might be used under certain conditions).

  • Page 63: Figure 66. Hart A) Find-Me And B) Device Found

    Series D12 LEL Gas Transmitter with Catalytic Bead Sensor Poll_Addr The Poll_Addr variable sets the polling address of the transmitter. The default value is 0, which allows the transmitter to communicate digitally, while preserving the function of the 4-20mA output. The value may be set from 1 to 15, which fixes the output at 4mA, and disables analog signaling.

  • Page 64: Modbus

    Series D12 LEL Gas Transmitter with Catalytic Bead Sensor Modbus Modbus is a master/slave protocol that supports a single master, and up to 247 slave devices on a common bus. The RS485 interface physically limits this number to 32 (1 master, 31 slaves), and RS232 restricts communication to a master and a single slave.
