WARNING – EQUIPMENT SHALL BE CONNECTED TO AN APPROVED POWER SOURCE OR BARRIER THAT DOES NOT PROVIDE MORE THAN 24VDC AND 8A.

  • Page 7: Background

    2.1 Power The Sasquatch requires a DC power source with a voltage of 5 V to 24 V. Power must be supplied while waiting for an arrival and during any time the interface will be accessed as there is no internal battery.

  • Page 8: Dry Contact Input

    Most magnetic sensors available on the market are designed to act as a dry contact, so the Sasquatch can easily be used as a replacement sensor for any system. A dry contact input on a controller features an internal pull up resistor.

  • Page 9: Communications Port

    COM – An additional ground connection to be used with an RS-485 connection. 2.3.1 Communications Settings The settings for the communications port are fully configurable so that the Sasquatch can be used with any other RS-485 compatible communication device. The following outlines the parameters that can be configured.

  • Page 10: Modbus Slave

    Figure 4 – RS-485 Connection 2.3.3 Program Mode When the sensitivity dial is set to 0, Sasquatch enters a mode where it listens for external commands on the RS-485 COM port. Using ETC Vision, you can program new firmware, change the operating mode, and adjust the sensitivity levels.
  • Page 11 2.3.4.2 Using the Link Device Connection Adapter Use the Sasquatch device cable that came with Link to connect to the device. Before connecting Link to Sasquatch, ensure that the switch on Link is set to position 1 (the leftmost position).

  • Page 12: Sensitivity

    4, which is the middle of the range. The higher the number, the more sensitivity or lower the threshold. When set to 0, the Sasquatch enters the program mode, does not take magnetic readings, and does not operate the switch.

  • Page 13: Adjusting The Default Sensitivities

    4.2 Capture - Full Debug This mode will run just like the normal mode, except the RS-485 port is used to stream live data to ETC Vision. This data includes the current readings, baseline, current switch position and velocity. Run a capture in ETC Vision to see the real time stream of these values.

  • Page 14: Configurable Options

    5 Configurable Options The following parameters can be used to modify the way that the Sasquatch operates. This allows for maximum flexibility for a variety of different applications. 5.1 Output Switch Parameters These parameters are used for one or more of the modes of operation in the following section.

  • Page 15: Velocity Scaled

    5.2.2 Velocity Scaled This allows for the velocity information to be transmitted along with the switch closure. The switch will always close for the Minimum Output Hold Time as above, but will be held closed for an additional time that is calculated based on the Output Hold Scale parameter. In the example below, the Output Hold Scale is set to 10 ms per m/min of velocity, which is the default.

  • Page 16: Detection Algorithm Timers

    The mass of the plunger in thousandths of a pound (x1000 lbs) or grams. This is required in order for the Sasquatch to calculate accurate kinetic energy of the arriving plunger as it hits the lubricator. If this information is not provided, the velocity-based lubricator / spring alarms will still operate.

  • Page 17: Hard Arrival Kinetic Energy Threshold

    Associated Alarm: Consecutive Hard Arrival Alarm 5.4.7 Cumulative Hard Arrival Threshold The Sasquatch counts the number of arrivals above the Hard Arrival threshold. If this count exceeds the Cumulative Hard Arrival Threshold, and alarm flag is set. These do not need to be consecutive hard arrivals to trip the alarm.

  • Page 18: Date And Time

    The date/time defaults to January 1, 2000. This is non-persistent and should be set after powering up the Sasquatch. The Date/Time Set flag can be queried to see if this has been done. The logs will use this information to timestamp each log entry. If the date/time is changed, all new log entries will use the new date/time.

  • Page 19: Table 2 - Lubricator / Spring Wear Settings

    The Sasquatch allows you to specify alarm thresholds in either velocity or kinetic energy units. It is up to the user to decide which to use. Velocity thresholds may be more familiar to some users but requires a manual calculation to check that it is within the lubricator specifications.

    This means that even if the case comes in contact with a surface that has a stray voltage; it will not be transmitted back through the wiring to the controller. Please do keep in mind that any shielding on the cable that is connected to the case of the Sasquatch will act as a path for any stray voltage to travel.
