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.
5.1.1
Minimum Output Hold Time
This sets the minimum time that the output switch is closed when the plunger arrives. In some modes,
this will be extended based on the behaviour of the plunger or its velocity. The default is 1000 ms or 1 s.
5.1.2
Output Hold Scale
This is a scaling parameter used to extend the close time of the switch in relation to the velocity of the
plunger. The default is 10 ms per m/min of velocity.
5.2
Output Switch - Modes of Operation
The behavior of the switch can be modified to operate in one of 3 modes to integrate better with
different systems.
5.2.1
Static Time
This mode ensures that the output signal is held for a specified amount of time each time that the
plunger arrives. The default Minimum Output Hold Time is 1 seconds. The length of the output switch
closure does not get extended while the plunger is moving in front of the sensor. Another switch
closure will not occur until after the plunger has departed (5 Departure Detection Periods have passed
without seeing the plunger; typically 5 s) and arrived again.
