3.0 Installation of the EX-6120, 6165 S

AUTION

Area must be declassified during installation.

The EX-6120, 6165 S

ERIES

IR gas sensor/transmitter (S/T) is a 3-wire, 24 VDC 4-20 mA S/T for the detection of

ERIES

combustible gas. The S/T is meant to be used in conjunction with an appropriate power supply and controller. The EX6120, 6165 S

ERIES

IR sensor/transmitter is in an enclosure rated for use in area listed below:

IECEx SIR08.0009X,Code EX d IIC SIRA 08atex1031x, Code EX d IIC IEC 60079-0 : 2004 (Edition 4) EN 60079-0 : 2006 IEC 60079-1 : 2007-4 (Edition 6) EN 60079-1 : 2007 T4 (Ta-20 to +60 deg C) 1 & 2 Class I, Division 1, Group A, B, D & D

Appropriate wiring, conduit and fittings are required for proper installation in an explosion proof rated environment.

AUTION

: Since the sensor/transmitter detects gas only at the sensor location, pay attention to the possible sources of gas,

the density of the gas, locations where the gas may be confined and locations where the gas may damage or injure property or personnel, when choosing locations of sensor/transmitters.

Take into consideration environmental factors when deciding on S/T location. Avoid locations where the S/T may be damaged by liquid immersion, excessive heat or other known hazards. Also, take precautions to insure condensation inside of the conduit does not enter the S/T.

3.1 Mounting the EX-6120, 6165 S

ERIES

IR Enclosure

Mount the enclosure, using the two mounting holes provided see Figure 2. Pay particular attention to the source and density of the gas being detected when choosing the location. Mount the S/T near the ceiling for lighter than air gases /vapors and near the floor for heavier then air gas/vapors. Contact ENMET if you have questions regarding your application.

AUTION

: Before connecting S/T to controller remove the power source to controller. Failure to do so may cause damage

to sensitive components.

ERIES

IR for Connection to a Control Unit

The cable entry threads are 20mm, ½” or ¾” NPT female. The EX-6120, 6165 S

ERIES

IR enclosure is manufactured from die cast aluminum*. Therefore, the use of glands,

conduit fittings and blanks made from brass should be avoided because if moisture is present, bi-metallic corrosion may occur due to the chemical reaction between the two materials.

Glands and fittings plated with nickel, tin or zinc will provide improved protection but in harsh environments the use of stainless steel is recommended.

A.1 Analog Output Calibration

The analogue output is that of a current source. In order to calibrate the output it is necessary to monitor the output signal. This can be performed in one of two ways:

Current measurement:

Connect an ammeter (or multimeter set to measure current in the mA range) in series with the analogue output.

FGD10 Analogue Output (4 – 20mA)

– +

Advantage: Direct measurement of output. Disadvantage: The analogue output has to be disconnected to allow the connection of the meter.

Voltage measurement:

Permanently connect a 10R resistor in series with the analogue output. When calibration is required, connect a voltmeter (or multimeter set to measure voltage in the mV range) across the 10R resistor.

FGD10 Analogue Output (4 – 20mA)

– +

10R

Advantage: No need to disturb wiring between EX-6120, 6165 S Disadvantage: Measurement accuracy dependent upon resistor tolerance.

A.1.1 Analogue Output Zero

• Monitor the current sourced from the analogue output of the EX-6120, 6165 S

• From the menu system select menu option: E: 4 and press ENTER.

• Using the INCREASE and DECREASE buttons; adjust the output to the required level (4mA or 40mV).

• Press ENTER.

OTE

: Pressing the MENU button rather than the ENTER button exits the zero feature without performing the

calibration.

A.3 Communications Protocol

The communications protocol used by the EX-6120, 6165 S connected via an RS232 connection at 19200 baud, 8 data bits 1 stop bit, no parity. This point-to-point, P2P, protocol is a frame-based protocol.

A.3.2 Control Byte Constants

The following control byte constants are used in the P2P protocol.

Read, RD = 0x13 (00010011)

Data Link Escape, DLE = 0x10 (00010000)

Write, WR = 0x15 (00010101)

Acknowledge, ACK = 0x16 (00010110)

Negative Acknowledge, NAK = 0x19 (00011001)

Single Data Frame, DAT = 0x1A (00011010)

End of Frame, EOF = 0x1F (00011111)

Write Password 1, WP1 = 0xE5 (11100101) Write Password 2, WP2 = 0xA2 (10100010)

A.4 Frame Structure

The start of a frame is indicated by a DLE byte followed by the type of frame to follow (RD, WR, ACK, NAK, DAT). The end of frame is indicated by a DLE byte followed by an EOF byte.

Note: Each of the constants has bit 4 set and so is slip-resistant (i.e. if shifted this bit will be out of position). The values have a Hamming Distance of 2 (each code is at least 2 bits different from every other code).

Any DLE bytes that occur between a frame’s start and end are prefixed with another DLE (byte-stuffing). Following the EOF is a 16-bit checksum of the entire frame, each byte is added to produce the checksum.

A.4.1 Variables

Each piece of accessible data on a device is referred to as a Variable. Each variable is referenced by a Variable ID. A variable ID may be any number of bytes long.

The available Variables and their corresponding Variable IDs depend on the type of device, but here are a few examples for the EX-6120, 6165 S

The structure of the data returned in each variable usually depends both on the type of device and the version of firmware running on the device.

Refer to device documentation for more information.
