READ BEFORE OPERATING

• All individuals who have or will have the responsibility of using, maintaining, or servicing this product must carefully read this manual. The product will perform as designed only if it is used, maintained, and serviced in accordance with the manufacturer’s  instructions.
• The B6 is a state-of-the-art dual-sensor gas transmitter that can operate as an independent, stand-alone system or as part of an integrated system. Setup procedures are simplified with user friendly push buttons and LCD menus.
  The B6 is the Q6 gas transmitter with BACnet® MS/TP master protocol. B6 consists of B6M and Q6R.
• BACnet MS/TP protocol is a peer-to-peer, multiple master protocol based on token passing. Only master nodes are allowed to send and receive tokens on the MSTP network. Passive slave nodes on the other hand may only transmit data frames on the network  in response to a request from a master node. Passing the token represents overhead in the sense that the messages used for managing the token do not carry data that is useful to automation or monitoring.
• The B6 can be set to be a Master Node or a Slave Node in the field. Factory default is master node.
• B6M: B6 Main unit with smart sensor, relay, digital port, display and keypad
• Q6R: Q6 Remote unit with smart sensor only

NOTE: Mounting Heights

• Low = 9-18 inches (0.25-0.5 meters) from floor
• Mid = 4-6 feet (1.25-1.75 meters) from floor
• High = 9-18 inches (0.25-0.5 meters) from ceiling

Installation

Enclosures Physical Dimensions

The enclosure is a NEMA 4 rated enclosure and can be wall mounted with 4 screws. To maintain the NEMA rating, it is important that the conduit opening is sealed upon installation.

Location

• The transmitter should be mounted where the gas to be measured is most likely to be present. This location will be dependent on the source of the target gas and whether that gas is lighter or heavier than air. Air circulation and mixture should also be taken into account.
• CO gas is lighter than regular air, it can be mounted on the walls at least a couple of feet below the height of the ceiling. As the transmitter has a digital read-out, placing it at about eye level is strong recommended.
• The location should be accessible for the purposes of routine re-calibration and periodic sensor replacement. Sufficient room should be left to allow the enclosure cover to be removed and the connection of the calibration adapter to the sensor chamber. For sensor element replacement there will need to be enough room to remove enclosure cover and the sensor board assembly.
• NOTE: The transmitter can also be installed in limited outdoor environment – An ambient air environment that is not climate controlled and is not in direct contact with the elements of nature, such as wind, rain, sleet or snow. Examples of limited outdoor environments include parking garages, construction complexes, sports venues, boats and recreational vehicles.
• NOTE: Avoid mounting the transmitter near 600 VAC switchgear and other sources of radio frequency and/or electromagnetic interference. While RFI/EMI protection is built in to the transmitter, excessive levels of interference may cause instability in the output signal.

Terminals 

Q6R Terminals

Wire and Cable

• Terminal blocks TB1 to TB7 accept 12 AWG to 24 AWG wire. Use 16 AWG or 18 AWG wire for the power supply in long wiring runs, which can be up to 1km (1,000 meters) long.
• We recommend using BELDEN 9841 for communications. This wire has 120 ohm input impendence, which will eliminate RS-485 communication problems.

Power Requirements

• The B6M and Q6R power supply voltage requirements are nominally 24VAC or 24VDC.
• The B6M and Q6R both have full wave rectifier and half wave rectifier on board. You will damage devices if you mix half wave and full wave rectifiers on the same AC source. Use extreme caution when sharing a common AC source. Sharing a common DC source is less problematic.

RS-485 Terminator
The terminator on each end of the RS485 run is designed to match the electrical impedance characteristic of the twisted pair wire, and will prevent signal echoes from corrupting the data on the line. The terminator should be enabled on BOTH ends of the RS485 run. Short and medium length Modbus/485 runs can operate without the terminating resistor. Longer runs may require the terminating resistors. But adding terminator dramatically increases power consumption.

The factory default setting is disabled terminator.
The B6 supplies this resistor on the main board, and it is chosen using a jumper at J4.

• J4 1-2: Terminator Disabled / OFF (default)
• J4 2-3: Terminator Enabled / ON

RS-485 Driver Replacement
RS-485 lines in heavy industrial environments are sometimes subjected to magnetic disturbances causing sufficient inducted power surges to damage the driver integrated circuit (IC). This IC (U6) has a socket on the circuit card for ease of replacement in the field.

B6 Operation And Maintenance Manual

Relays Output

• The B6 has three onboard programmable Single-Pole Double-Throw (SPDT) relays. These relays can be used to control other equipment, such as fans, lights, horns, etc. eliminating the need for a separate controller.
• Three terminal blocks (TB1, TB2 and TB3) are located on the main board. Each relay can be programmed individually.

The switching capability of each relay is:

• 1.0 A maximum resistive load at 30 VDC
• 0.3A maximum resistive load at 125VAC

Note for B6:

• The B6 supports BACnet MS/TP protocol and can be networked to form a BACnet MS/TP network.
• The B6 default baud rate is 38400bps.
• Each B6 on the MS/TP network must have a unique BACnet MAC address and unique Device Instance Number (Object ID).
• B6 valid MAC addresses are 0-127 for master node, 0-254 for slave node.
• B6 default MAC address is 126.
• Default Device Instance Number (Object ID) is 4005.
• Avoid running communication wires or sensor input wires next to AC power wires or the relay output wires. These can be sources of noise that can affect signal quality.
• When the B6 input power is AC, make sure all devices on the network use same rectifier circuit. The B6M and Q6R both have full wave rectifier and half wave rectifier on board. You will damage devices if you mix half wave and full wave rectifiers on the same AC source.

Function and Configuration

Indicators
The indicators consist of five LED’s – two to indicate RS-485 digital communication, three to indicate the status of relays 1-3.

RS485-TX/RX:
When the B6 is connected to a controller system via RS-485, the traffic of the communication can be monitored visually through the two RS-485 indicators. One is RX LED, which indicates the data stream received in from the controller. The other is TX LED, which indicates the data stream out of the B6.

Note: If the TX LED or the RX LED is always ON, is indicative of a communication problem. See Troubleshooting for RS-485.

Relay 1-3 LED:
Indicate the status of each relay. When the relay is actuated/closed, the relay LED is ON. When the relay is de-actuated/open, the relay LED is OFF.

Note: If you set the relay to be Normally Energized (Fail Safe), the relay LED will turn ON at non-alarm state and turn OFF at alarm state, because the LED reflects the relay coil status.

Enabled:	Each relay may be individually set to be enabled or disabled. If it’s disabled, the relay will always de-actuate no matter what the current gas concentration.   Default is Enabled.
Normally   De- energized:	Each relay may be individually set to be normally energized or normally de-energized.   Default is normally de-energized.
Latching:	Each relay may be set to latch in actuate status until acknowledged by a front-panel action.   Default is Non-Latching.
ON Delay:	“Delay on Actuation” or “Delay on Make”. For each relay a separate time delay may be set from 0 to 990 seconds before an alarm condition will cause the relay to actuate.   Default is 5 seconds.
OFF Delay:	“Delay on De-Actuation” or “Delay on Break”. For each relay a separate time delay may be set from 0 to 990 seconds before a return to a non- alarming signal condition will cause the relay to de-actuate.   Default is 5 seconds.
Style:	Normal Relay Style: Work as normal relay.   Buzzer Style Relay: When the relay is used to control a buzzer or horn. Working as a buzzer style will make the relay have the same function as the buzzer. It will be switched off when performing the Hush Buzzer/Relay function in the Tool Menu.   Default is OFF.

Menu “8_BUZZER STYLE”
The buzzer style is almost identical to that of the relays, except the style that represents the buzzer tone options:

• Tone 1: Chirp once.
• Tone 2: Chirp twice.
• Tone 3: Intermittent 50% duty cycle.
• Tone 4: Continuous.

The menus are identical to those for the Relay Style.

Smart Sensor Assembly Replacement

Disassembling
Observe all safety and electrical codes and regulations before removing enclosure lid.

Important: Calibrate the transmitter whenever a component is replaced. But if you replace a smart sensor assembly with a sensor onboard from ACI, you don’t need to recalibrate the transmitter, as all the calibration information has been stored in the smart sensor board in the factory process.

Replacement Procedure
To replace the entire smart sensor assembly, complete the following steps:

1. Power down the transmitter.
2. Remove the four screws securing the enclosure lid assembly to the base enclosure and remove the enclosure lid assembly.
3. Remove the two screws securing the smart sensor board and remove the smart sensor board from the lid assembly
4. Feed the O-ring over the sensor on the new smart sensor assembly
5. Plug the new smart sensor assembly and secure with two screws. Ensure that the connectors are correctly matched. Incorrect installation may damage the sensor assembly and/or the display board.
