Welcome to G-TV!
Today, I will be showing you how to program the Simpson Hawk 3 series digital panel meter.
Many of the advance features of the Hawk 3 respond to, and interact with, each other.
Before programming the Hawk 3, it is important to know the order in which to set up these
features.
For our demonstration, we will program the decimal point, linearization or scaling, and
the set points and relay control.
I have wired the device to my power supply and the numbers 0000 are on the display.
I will begin programming by placing my decimal point in any one of the five locations.
To do this, push the left arrow to enter programming mode.
Now, I will use the arrow here to scroll up to the display control marked by DCTL.
Then I will press enter.
DP and 2345 should be flashing here.
I will press enter again and 2345 is now a fixed display.
I can place the decimal point using the up and down arrows.
I will place it here and hit enter.
I will now push the left arrow to save my changes.
For my next example I will program my meter to show 1 point linearization for a 150 DCA
application using a 50 DC mV shunt.
Since I am still in programming mode I can scroll up until I get to screen control.
This will be marked by a SCTL on the display.
I will push enter and LiN or linearization should be on the display.
I will press enter again and the display will be flashing between off and coordinate or
CORD.
When I hit enter, off will be a fixed display.
I can scroll up until 1 PT displays and then press enter.
The display here should flash between a number and ELE 1.
Once I hit enter, I can adjust my value using the arrow keys.
Since I want 200.0, I only want to change the negative sign to a positive.
If I scroll to the left pass the 2, the screen should display sign and I can push up once
to remove the negative sign.
I will hit enter and a different number with DSP 1 should be flashing.
Press enter here to and change the value.
For my demonstration, I will change the number to 600.
I will scroll left to the last digit and push up until I get to 6 and then push left one
more time to remove the minus sign as I did in the previous step.
Once I am finished, I will push enter and then left to save changes.
To edit my set points and relays, I will enter programming mode and scroll up until I get
to the SP 1, and then hit enter.
The display should flash between UAL and a number.
I will hit enter and change the number to my desired value.
For this example, I will change the value to 100 and push enter.
Right now DLAY and RSP should be flashing, I will push enter again to set my relay response.
I can choose between delay, latch or hysteresis.
Only one of these can be set, but I will go through each one to show you how to set the
parameters.
For Delay the parameter will actuate the given relay after a set amount of time when past
the set point setting.
This parameter can be adjusted by going to D Low, if I hit enter I can adjust the amount
of delay time.
The display will now show D Hi and I can enter the amount of delay time here and press enter.
For Latch, the parameter will actuate the given relay.
To reset manually, push enter slash reset.
To set latch, after I changed my UAL value, I can scroll up until I get to LTCH and hit
enter.
LTCH and a number should be flashing.
I will press enter and enter the amount of delay desired before the relay actuates.
When I am finished, I will press enter.
For Hysteresis, I can set the percentage above or below the set point where the relay will
actuate.
I will scroll up to the third value after Latch and delay and then press enter.
The display will show H Low and a number.
I will press enter and change the percentage of hysteresis falling edge and push enter.
The display will now show H Hi.
Once I push enter, I can change the percentage of hysteresis rising edge.
Then push enter.
After I have set one of the three responses of display, latch, or hysteresis, I can set
my alarm to High, Low or off.
I will push enter and pick one of the three, the push enter again.
My next step is to choose the state of the relay to be normally energized NE or normally
de-energized ND.
When the display flashes, I will push enter and choose my desired state.
I will hit enter to return to the main menu.
Using these steps, I can adjust SP2, SP3 and SP4 as necessary.
