The Q6 is a state-of-the-art dual-sensor gas monitor that can operate as an independent, stand- alone system or as part of an integrated system. The Q6 connects with digital interface to ACI Q-Controller or M-Controller, or any PLC/DCS through Modbus RTU protocol. Setup procedures are simplified with user friendly touchable buttons and LCD menus.

Q6 Operation And Maintenance Manual 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 Location The transmitter should be mounted where the gas to be measured is most likely to be present.
AC source. Use extreme caution when sharing a common AC source. Sharing a common DC source is less problematic. • ACI Q-Controller uses half-wave rectifier only, M-Controller uses full-wave rectifier only, so the Q6 can work with both controllers •...

Q6 Operation And Maintenance Manual 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 Q6M is connected to a controller system via RS-485, the traffic of the communication can be monitored visually through the two RS-485 indicators.
3.2.4 Reset MENU Password If you forgot the main menu password, you can reset the menu password to default password “4321” by entering a correct active code. For the active code, contact ACI. 3.2.5 Exit Tool Mode Press key [F3] to return to monitoring mode.
Q6 Operation And Maintenance Manual 3.3 Main Menu Tree The main menu is password protected. Once the password is accepted, you are allowed into the main menu tree. Factory default password is 4321. Note: While in the menu tree, all normal monitoring operations stop. The alarm status does not change.
Q6R address would be address + 1 Note: In Modbus protocol, the address 0 is for broadcast. Baud rate: Define baud rate for RS-485 communication with ACI controllers OptoMux protocol or other SCDA system with Modbus protocol. Q6 default baud rate is 4800 bps Scroll Rate: In normal operation, the sensor and relay status information scrolls automatically.

Q6 Operation And Maintenance Manual Adjust real time clock. ADJ Clock: Adjust the LCD contrast. Valid values are between 10 (light) and 50 (dark). Contrast: Default is 21. Q6 Sensors: If the smart sensor in Q6M unit is not installed, it can be disabled here, so the Q6M will not detect the smart sensor board and will not report any fault on the sensor offline If the smart sensor in Q6R is not installed, it can be disabled too.
Q6 Operation And Maintenance Manual 3.5 Menu “2_ZERO CAL” First to select which sensor is going to be calibrated, Q6M or Q6R? The subsequent zero calibration will be performed on that sensor. The calibration is using a two-point calibration process. First, use a “Zero Gas”, then use a “CAL Gas”...

Q6 Operation And Maintenance Manual 3.9 Menu “6_ALARM SETUP” First to select which sensor’s alarm is going to be set, Q6M or Q6R? The subsequent alarm settings will be performed on that sensor. The Q6M supports alarm 1 to alarm 8 on its sensor. The Q6R supports alarm 1 to alarm 8 on its sensor too.
Q6 Operation And Maintenance Manual 3.10 Menu “7_RELAY STYLE” Each relay may be individually set to be enabled or disabled. If it’s Enabled: disabled, the relay will always de-actuate no matter what the current gas concentration. Default is Enabled. Each relay may be individually set to be normally energized or normally Normally de-energized.
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. 4. MODBUS Protocol Supported By Q6 For Modbus protocol, please contact ACI. 86650-001-000 RB Feb 22, 2019...
Important: Calibrate the monitor 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 monitor, as all the calibration information has been stored in the smart sensor board in the factory process.
