Iron Man monitor has two sensitivity settings of 0 to 5 volts and 0 to 50 volts.
If the desired alarm setting is to be in the range from 0 to 50 volts, you will first have
to change the sensitivity.
We will cover changing the sensitivity in another video.
The “Iron Man” monitor comes preset from the factory with a sensitivity of 0 to 5 volts
and the alarm level at 2.5 volts.
This means that if there is an electrical overstress higher than 2.5 volts, Iron Man
will give you both an audible and a visual alarm.
To setup this alarm level, you need a DC Power Supply that can provide you with a 50 volt
signal.
Your first step is to adjust the DC Power Supply out to a desired voltage. For this
demonstration we will set the limit to a 3 volt signal.
Connect the ground wire from the Iron Man to the Lo or Common side of the DC Power Supply.
Connect the ring terminal wire to the board terminal on the front of the iron man.
Connect the ring terminal wire to the Hi side of the DC Power Supply.
Using a small screwdriver, adjust the potentiometer on the back of the unit fully to the counter
clockwise position.
The alarm should now be on and the red light on the “Iron Man” workstation monitor
will be lit.
Now adjust the potentiometer slowly clockwise until the alarm turns off. You should now
be under 3 Volts.
Change the set point on your DC Power Supply to 2 volts.
The alarm should now be off and the green light on the “Iron Man” workstation monitor
should be turned on.
Turn the voltage up on the DC Power Supply and you will hear the alarm and see the red
light when the voltage reaches 3 Volts or above.
