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. - Page 4 Q5 Operation And Maintenance Manual 3 Relays SPDT, Dry contacts Relays: • 1.0A maximum at 30 VDC (resistive load) • 0.3A maximum at 125VAC (resistive load) 80 db at 10 cm, 2700 Hz Buzzer: Buzzer 1, 2, 3: Programmable tone...

10VDC 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. -
Page 10: Relays Output
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. -

1-3. 3.1.1 RS485-TX/RX When the Q5 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 Q5. -

M-Controllers support RS-485 addressing from 0 to 31 for digital sensors. Address: Q4 Controllers support RS-485 addressing from 0 to 3 for digital sensors. The Q5 RS-485 address can be defined from 0 to 255. Default is 3. Note: In ModBus protocol, the address 0 is for broadcast. Baud rate: Define baud rate for RS-485 communication with QEL controller protocol, ModBus protocol or BACnet protocol. - Page 15 Q5 Operation And Maintenance Manual When Q5 is connected to an M-Controller or a Q4-Controller, the protocol Protocol: should be set to OptoMux. The Q5 Default protocol is OptoMux. The Q5 also supports ModBus protocol, responds as a ModBus Slave using RTU protocol.

Page 26: Smart Sensor Assembly Replacement
Important: Calibrate the transmitter whenever a component is replaced. But if you replace a smart sensor assembly with a sensor onboard from QEL, 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. -
