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 Q5 is a state-of-the-art transmitter that can operate as an independent, stand-alone system
or as part of an integrated system. The Q5 connects with analog and digital signals to virtually
any controller, PLC, or DCS. Setup procedures are simplified with user friendly push buttons
and LCD menus.

The Q5 IR-Probe is a Q5 with a remote sensing probe that uses the technique of NDIR (Non
Dispersive Infrared) to monitor the presence of hydrocarbons and carbon dioxide. The distance
between the Q5 and the IR-Probe can up to 100 meters. A 5 meter cable is included in the
package.

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

Q5 Terminals

85950-001-000 RF August 7, 2015

Q5 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 Q5 Digital Connection

2.2.3 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

85950-001-000 RF August 7, 2015

Q5 Operation And Maintenance Manual

may require the terminating resistors. But adding terminator dramatically increases power
consumption.

Factory default setting is disabled terminator.

The Q5 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

2.2.4 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.

2.2.5 4-20mA and 1-5VDC / 2-10VDC Analog Output

The Q5 provides one-channel 4-20 milliamp analog outputs and programmable 1-5VDC / 2­10VDC analog output at the same time. The maximum output impedance is 600 ohms for the
4-20mA output. The maximum output current is 10 mA for the 1-5VDC/2-10VDC output.

Test point SIG+ and SIG- are used to measure the current inline when the Q5 is working in the
field.

The 1-5VDC/2-10VDC output can be selected through the menu. Default setting is 1-5VDC
output.

The analog output may be defined in complex ways allowing assignment of different values to
both 4 milliamps and 20 milliamps. You may even assign a gas concentration to 4 mA, which
is higher than the concentration assigned to 20 milliamps. The Q5 will draw a straight line
between them. There is no need to assign gas concentration to 1V-5VDC/2V-10VDC. When

85950-001-000 RF August 7, 2015

Q5 Operation And Maintenance Manual

9

the Q5 outputs 4mA, it also outputs 1VDC or 2VDC. When the Q5 outputs 20mA, it also
outputs 5VDC or 10VDC, which follows the 4-20mA output.

If there is any fault found in the Q5, it will output 2.5mA and 1VDC at 2-10V output or

0.5VDC at 1-5VDC output to indicate the fault.

2.2.6 Relays Output

The Q5 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

2.2.7 Note for Q5:

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 Q5 input power is AC, the 24VAC must not be grounded. A dedicated floating
24VAC may be needed if other nodes on the network are grounded, otherwise a DC power
supply is recommended.

2.2.8 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 Use-Part 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.
