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 monitor Q6M has a digital read-out, placing it at about eye level is strong recommended. The Q6R is the remote unit, so it can be placed at any location according the target gas source.
  • 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 monitor 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 monitor near 600 VAC switchgear and other sources of radio frequency and/or electromagnetic interference. While RFI/EMI protection is built in to the monitor, excessive levels of interference may cause instability in the output signal.

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 Q6M and Q6R power supply voltage requirements are nominally 24VAC or 24VDC.
The Q6M and Q6R both have full wave rectifier and half wave rectifier on board. If the Q6 works alone, the 24VAC/DC can connect to either full wave rectifier or half wave rectifier connectors. If the Q6 connects to controllers, 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.

  • ACI Q-Controller uses half-wave rectifier only, M-Controller uses full-wave rectifier only, so the Q6 can work with both controllers
  • When the Q6 shares a common AC source with a Q-Controller, use the half wave rectifier connector Q6M TB5 and Q6R TB2
  • When the Q6 shares a common AC source with an M-Controller or Q4 Controller, use the full wave rectifier connector Q6M TB4 and Q6R TB1

Q6 works alone

Q6 Connection with Q-Controller

Q6 Connection with M-Controller

RS-485 Terminator
Factory default setting is disabled terminator.
The Q6M 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.

Relays Output
The Q6M 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

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 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. 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 Q6M.
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.

  • Apply the calibration gas.
  • Wait for about 3 minutes or until the reading is stable.
  • Press key [F3] to confirm SPAN CAL.
  • When the device is in span cal, it will take 10 seconds to 1 minute to complete.
  • When the span cal operation is over, the device will display “Accepted” and return to “3_SPAN CAL”.
  • Make sure there is no Cal Error displayed. If Cal Error is reported, repeat the procedures above. If the Cal Error is still showed up, the sensor maybe expired.
  • Remove the gas.
  • Exit menu to Monitoring Mode.

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 normally energized or not normally energized.
  • According to UL2075 standard for safety, the Q6 Endurance Test will automatically perform 6000 cycles of Relay/Buzzer On and Off operation at a rate of not more than 15 cpm.
    Note : The 4mA (1VDC/2VDC) and 20mA (5VDC/10VDC) outputs are not available for Q6.

Menu “5_VIEW SETTING”
This function is to verify the settings for the alarms, relays, buzzers and analog outputs.
Note : The View of A-Out Setup is not available for Q6.

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

Disabled or Enabled:

|

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.

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

Maintenance

Smart Sensor Assembly Replacement
Disassembling
Observe all safety and electrical codes and regulations before removing enclosure lid.

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.

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

  1. Power down the monitor.
  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.

Accessories

Note: For Duct Mount Installation, Q6 needs both the Pump-thru Kit and Duct Mount Kit.

Q-View is Windows based software running on a PC to used configure Q6 sensors through an RS-485 network. It supports the ACI controller protocol (OptoMux) and ModBus protocol.
