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 B5 is a state-of-the-art 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 B5 and the B5 IR-Probe are the Q5 and Q5 IR-Probe with BACnet® MS/TP master
protocol. Therefore, the B5 and the B5 IR-Probe do not support the 4-20mA and VDC
analog output.

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 B5 and the B5 IR-Probe can be set to be a Master Node or a Slave Node in the field.
Factory default is slave node.

2. Installation

2.1 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.

2.2 Terminals

B5 Terminals

85950-101-000 RB August 7, 2015

B5 Operation And Maintenance Manual

7

2.2.1 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.

2.2.2 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.

Factory default setting is disabled terminator.

The B5 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

2.2.3 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.

2.2.4 Relays Output

The B5 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.

Switching capability of each relay is:

• 1.0 A maximum resistive load at 30 VDC

• 0.3A maximum resistive load at 125VAC

85950-101-000 RB August 7, 2015

B5 Operation And Maintenance Manual

2.2.5 Note for B5:

The B5 supports BACnet MS/TP protocol and can be networked to form a BACnet
MS/TP network.

The B5 default baud rate is 38400bps.

Each B5 on the MS/TP network must have a unique BACnet MAC address and unique
Device Instance Number (Object ID).

• B5 valid MAC addresses are 0-127 for master node, 0-254 for slave node.

• B5 default MAC address is 126.

• Default Device Instance Number (Object ID) is 4005.

The B5 power supply and RS-485 connection are similar to the Q5. The B5 doesn't have
terminal blocks TB4 and TB6.

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.

The B5 has a 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.

When the B5 input power is AC, the 24VAC can be either grounded or non-grounded.
Polarization is very important when the B5 is connected to a network. Make sure the
Neutral is connected to the GND of TB5.

2.2.6 Certification:

The Q5/B5 series have been certified to the following Standard:

Safety requirement for Electrical Equipment for Measurement, Control, and Laboratory Use­Part 1: General Requirements CAN/CSA-22.2 No. 61010-1 Third Edition, Dated May 11, 2012;
And
Safety Requirements for Electrical Equipment for measurement, Control, and Laboratory Use­Part 1: General Requirements UL 61010-1 Third Edition, Dated May 11, 2012.

Installation must be in accordance with ANSI/NFPA 70, National Electrical Code (NEC);
the
Canadian Electrical Code (CEC), Part I, CSA C22.1, and CSA C22.2 No. 0; and the
Manufacturers’ installation instructions

The Q5/B5 series have not been tested for Life Safety Applications and are not to be used in
Life Safety Applications in jurisdictions that require this certification

3. Function and Configuration

3.1 Indicators

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

3.1.1 RS485-TX/RX:

When the B5 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 B5.

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

3.1.2 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.

3.7 Menu “4_OUT TEST”

During system installation and testing, it may be necessary to force relays and buzzers on
and off.

The Relay Testing feature allows the user to force the actuation of each relay. This
function forces an Actuate vs. De-actuate action, not an energized vs. non-energized
action. Therefore the user must be aware of these relays, which have been defined as

3.9 Menu “6_ALARM SETUP”

The B5 supports alarm 1 to alarm 8.

Alarm is a programmable condition that can receive a selectable input and trigger relays
and buzzers.

Disabled or

Each alarm may be individually set to be enabled or disabled. If the alarm
is disabled, the alarm will not be used to calculate or trigger anything.

Enabled:

Default: Alarm 1 to Alarm 4 is enabled. Alarm 5 to Alarm 8 is
disabled.

Input: One of five inputs is selected to calculate the alarm condition status to

trigger the selected outputs:

• INSTANT: instantaneous gas reading.

• 15 MIN AVG

reading over 15 minutes.

• 8 HOURS AVG (TWA): 8-hour Time Weighted Average, average
reading over 8 hours.

• DAILY PEAK: daily peak reading.

• FAULT: If the unit reports any faults,

concentration, it will trigger the selected outputs.

Alarm On

If Alarm On is greater than or equal to Alarm Off:

and

Alarm Off

Alarm On: Sets the concentration at or above which the relay will actuate.

Alarm Off: Sets the concentration at or below which the relay will de­actuate.

Reading:

If Action On is less than Action Off:

Action On: Sets the concentration below that the relay will actuate.

Action Off: Sets the concentration above that the relay will de-actuate.

Trigger: Trigger Outputs: Relay 1, Relay 2, Relay 3, Buzzer 1, Buzzer 2, Buzzer 3

Enabled:

disabled, the relay will always de-actuate no matter what the current gas
concentration.

Default is Enabled.

Normally

Each relay may be individually set to be normally energized or normally
de-energized.

De­energized:

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 non­alarming 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.

3.11 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.

3.12 Menu “A_ALL DISABLE”

This function is for calibration, system testing etc. When All Disable is ON, the status of
the relay, buzzer and analog output, etc., will freeze in their current state.

Default is OFF.

3.13 Menu “B_SIMULATION”

Simulation mode is used to assist in testing the installation before commissioning. When
simulation is enabled, the unit will not detect gas concentrations; it will display the
simulated value and use it to calculate the status of relays and buzzers. This feature is
available for evaluating the user settings and testing the installation (e.g.: the activation of
the valve, fan speed, relay set points, etc. can be verified.)

Any concentration between 0ppm and 9999ppm can be simulated.

3.14 Menu “C_SITE SERVICE” and “D_FACTROY SET”

Factory service staff access only. The customer has no need to operate it.

B5 Operation And Maintenance Manual

22

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.

4.1.2 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.
