Sweep

sweepscreen.pngThe Sweep Cycle is use to automatically ramp up and down through analog values.  This cycle can be entered in any of the three analog modes:  Current 2-Wire, Current Source, or Voltage Source, by pressing the OK button while in one of these modes.

Once the OK button is pressed, the menu to the top right will appear.  Select the first option of "Sweep Cycle".

Then you will see the menu on the bottom right.  There are three parameters associated with the Sweep Cycle.

  • Full Sweep Time - This is the time from that the device will ramp from the Start Value to the Final Value.
  • Start Value - This is the initial value that the Sweep Cycle will begin at.
  • Final Value - This is the value that the Sweep Cycle should end at.

Once you have the above parameters configured, select "Run Cycle" and press the OK button.  The simulator will go from the start value to the final value over the full sweep time then back to the start value of the same full sweep time then repeat.

While running the Sweep Cycle, pressing the OK button will pause the sweep Cycle, holding the output at it's current value.  Pressing the OK button again will resume the Sweep Cycle.



 


Step

stepscreen.pngThe Step Cycle is use to automatically increment the step size up and down through analog values.  This cycle can be entered in any of the three analog modes:  Current 2-Wire, Current Source, or Voltage Source, by pressing the OK button while in one of these modes.

Once the OK button is pressed, the menu to the top right will appear.  Select the second option of "Step Cycle".

Then you will see the menu on the bottom right.  There are four parameters associated with the Step Cycle.

  • Step Time - The time between step increment/decrements.
  • Step Size - This is how much the analog value should change each time.
  • Start Value - This is the initial value that the Step Cycle will begin at.
  • Final Value - This is the value that the Step Cycle should end at.

Once you have the above parameters configured, select "Run Cycle" and press the OK button.  The simulator will begin at the Start Value, increasing or decreasing the Step Size each time the Step Time has lapsed until it reached the Final Value then going back to the Start Value and repeating.

While running the Step Cycle, pressing the OK button will pause the Step Cycle, holding the output at it's current value.  Pressing the OK button again will resume the Step Cycle.

 

 


Custom Profile

customscreen.pngThe Custom Profile Cycle is use to automatically index through a maximum of 10 values.  This cycle can be entered in any of the three analog modes:  Current 2-Wire, Current Source, or Voltage Source, by pressing the OK button while in one of these modes.

Once the OK button is pressed, the menu to the top right will appear.  Select the third option of "Custom Profile Cycle".

Then you will see the menu on the bottom right.  Here are the profiles associated with the Custom Profile Cycle.

  • Step Time - This is the time between indexes of the step values.
  • Number of Step - How many of the Value Steps (1-10) that should be cycled through.
  • Value Steps 1-10 - These are the analog output values that should be indexed through.

Once you have the above parameters configured, select "Run Cycle" and press the OK button.  The simulator will begin at Value Step 1, then after the step Time go to Value Step 2, then continuing indexing through the Value Steps as long as the Number of Steps has not been completed, then it will return the Value Step 1 and repeat.

While running the Custom Profile Cycle, pressing the OK button will pause the Custom Profile Cycle, holding the output at it's current value.  Pressing the OK button again will resume the Profile Cycle.

 

 


 

Engineering Unit Scale (Eng Unit Scale)

The Eng Unit Scale to be used to put the mA signal into a value that represents the units of the device that the analog simulator is replacing.  To change the engineering units scaling, from the Main Menu select Eng Unit Scale.  There are separate scales for current and voltage.  Set the EU High at the 20mA value and the EU Low at the 2mA value.

Example - Replacing an actuated ball valve that is closed at 4mA, 0 degrees and open at 20mA, 90 degrees.  By setting the Current EU High to 90, 4mA will be 0 degrees, 12 mA will be 45 degrees, 20 mA will be 90 degrees.

Resolution

The resolution that the signal is incremented by can be set to 1.0 for fast movement through the scale 0.1 for higher accuracy.  To change the resolution, from the Main Menu, select Device Options, then Resolution and select between 1.0 and 0.1.

Sleep Timer

The sleep timer can be used to save battery life by turning off the analog simulator after a set time.  This feature can be disabled by setting the Inactivity Off-Time to Off.  To change the Sleep Timer, from the Main Menu, select Device Options, then Sleep Timer and scroll up and down through the times.

About Device 

about.png

This screen gives you information such as the full part number, series, firmware revision, and serial number.

Pressing OK on the screen will bring up a QR code that you can scan to get to the full manual.

 


Open Wire

alp2openwire.jpg

The OPEN WIRE feature of the SIM-ALP2 is an important diagnostics feature for analog circuits.

If you see the "OPEN WIRE" banner below the analog signal then it means one of the following:

  • There is not a continuous path from the red terminal to the black terminal.
  • The resistance of the circuit is greater than 500 ohms.
  • The polarity of the circuit is backwards.
