    Failure to do so may be dangerous. Dispose of batteries per applicable local, state and federal regulations or contact Scott Health & Safety or your local Scott authorized distributor. NEMA-4X Wall Mounted Enclosure The enclosure measures 9.32 inches high x 9.19 inches wide x 5.38 inches deep (233 mm x 203 mm x 136 mm). It provides a watertight, dust tight and corrosion resistant enclosure for outdoor or indoor mounting.

  • Page 15: Display/Function Assembly

    Display/Function Assembly The individual visual display of absolute value of the gas concentrations, alarm status, and channel status for all active channels provides the status of the gas/flame detection system. Operator intervention and/or automatic alarm corrections can be made from the information displayed by this unit. Gas Concentration is displayed on a LCD in units of PPM, PPB, % and none (flame applications) in any combination of the four.

  • Page 25: System Operation

    System Operation General The QuadScan II allows up to 4 inputs of 0/4 - 20 mA and converts these inputs to digital displays on a LCD. An input current of 4 mA corresponds to a display of 0.00, and an input current of 20 mA corresponds to the programmed full- scale digital display.

  • Page 26: Current Loops

    Channel Status The channel status essentially provides a summary of the health of each active channel. Four LEDs are used, one for each of the 4 channels. Each LED provides 3 functions: Channel OK - Green Channel in Fail - Flashing yellow, (solid yellow when reset button is pressed) Channel Inhibited - Flashing yellow/green Alarm Status Each channel has 2 LEDs, warn (yellow), for low alarm status and alarm (red)

  • Page 27: Current Loop Outputs

    Flame detectors provided by Scott Health & Safety provide an increased output analog signal when a flame is detected. An alarm due to a decreasing concentration is activated (changes state) when the digital indication is at or below the set point and inactive when the digital indication is at or above the reset point.

  • Page 28: Figure 10 - Alarm Set For Increasing Or Decreasing Gas Concentrations

    This timed delay can prevent nuisance alarms that may occur due to such things as lightening storms, etc. The off time delay can be programmed for up to 10 seconds, and once activated the timer is decremented once a second until the time expires.

  • Page 29: Latching Alarms

    Latching Alarms Latching alarms describe the behavior of the software emulating a self latching relay. The coil is energized through one of its own contacts, thereby holding itself energized. This type of relay requires an interruption in the latching circuit for the relay to be de-energized. This is the function of the alarm reset button. This feature is implemented in software for alarms warn and alarms programmed with the latching option.

  • Page 30: Fail Relay

    However Scott Health & Safety has anticipated such situations and can provide an optional remote relay assembly, allowing alternative alarm combinations.

  • Page 31: Horn And Horn Relay

    By latching the existing alarm state, safety lights, horns and fans under control of the warn and alarm relays, they continue to operate, even if the current loop has shorted or opened, or the transmitter has ceased to operate. When an operator has determined that conditions are actually safe, the alarm reset may be pressed to de-activate alarm LEDs, and warn and alarm relays on that channel.

  • Page 32: Sensor Damping Constant

    Current Loop Input-A channel is inhibited when the current loop input is equal to the programmed inhibit level (factory default is 3.6mA). The channel inhibit is immediately removed when the current loop input is outside the tolerance of ±0.25mA. Sensor Damping Constant Provides a damping time constant which allows the program selection from 0 to 10 seconds.

  • Page 57: Optional Remote Relays

    Optional Remote Relays General The optional remote relay assembly offers a unique alarm system for all alarms generated from the QuadScan II, which include warn, alarm and fail. Warn refers to the first level of alarming while alarm refers to the second level (more serious) of alarming. The unit inputs the alarm signals, which can be programmed to provide a variety of relay configurations to change the state of the 8 relays, when an alarm condition exists.
