The Falcon Series digital indicators are premium quality
1/8 DIN meters for industrial applications. All Falcon units
feature selectable decimal point from the terminal block
and display scaling, providing wide application flexibility. In
addition, most signal input ranges are easy to change with
jumpers on the main board. The Falcon has a 0.56" bright
red LED display for high visibility.

Compactly designed for applications requiring minimal rear
panel depth, the Falcon fits a standard 1/8 DIN panel cutout (91.9mm x 45mm) and requires less than 3" behind the
panel. A screw terminal connector is a standard feature
for easy wiring of the power supply and signal input connections.
Engineering Label
Mounting Requirements
The Falcon series 1/8 DIN indicators require a panel cutout of 1.77"
(45mm) high by 3.62" (91.9mm) wide. To install the Falcon into a panel
cutout, remove the clips from the side of the meter. Slide the meter
through your panel cutout, then slide the mounting clips back on the
meter. Press evenly to ensure a proper fit.
Engineering Label Placement
If replacement of the engineering unit label is required, place the tip of a
ball-point pen into the small hole at the base of the engineering label in
the bezel. Slide the label up until it pops out. Grasp and remove. Slide
the new label half the distance in, then use the ball-point pen to slide it
down into place.

Input Signal: Connect the signal to be monitored to the IN HI and
IN LO terminals. IN HI is terminal #1, IN LO is terminal #2.
Supply Power: Connect the supply power to terminals #11 and
#12. Note that if AC power is supplied, terminal #11 is for Neutral,
and terminal #12 is for Hot. If DC power is used, terminal #11 is for
-DC, and #12 is for +DC.
Display Hold: This feature allows you to hold the displayed value
indefinitely. A remote switch can be used to make the connection.
To activate the display hold, short pins #3 and #4 (Hold and +REF).
This connection must be kept isolated from other circuitry. To hold
multiple units, separate poles of the switch must be used to maintain
the isolation.

These instruments are designed for maximum safety to the
operator when mounted in a panel according to instructions.
They are not to be used unmounted or for exploratory measurements in unknown circuits.
Before switching the instrument on, make sure the supply voltage matches the power source required of the instrument as
indicated on the hook-up label affixed to the instrument.

Decimal Point Selection
Decimal point selection is done at the rear screw terminal block for
the 2A and 5A input range units.
From terminal block: The decimal point can be set from the rear
screw terminal block by connecting the appropriate decimal point
(DP 1, 2, 3) to the DPC terminal. The J105 jumper block must be in
the D position (see diagram under "From front panel.")
The 2A and 5A units do not have the J105 jumper block.

Current Range Selection
All Falcon Indicators are configured initially per the customer specifications. Range changes can be accomplished as follows:
Disconnect power from the unit. Remove the unit from the panel.
Remove the front bezel by inserting slotted screwdriver in the vertical
slots on either side of the bezel and then turning to pry the bezel off.
Unscrew the two Phillips head screws at either side of the circuit board.
Finally, push on the green connector assembly in the back of the unit
to slide the main circuit board out from the meter. Change jumpers
according to the chart below.
Note: If a new range is selected, the calibration procedure must also
be performed.
Input J102 J106 JU101 JU102
Range
200 A A R A No
2mA B R A No
20mA D R A No
200mA E R A No
If you need to change a
Falcon from (or to) a 2
amp or 5 amp unit, please
consult the factory or an
Authorized Service Center.
Note: JU101 and JU102 are hard wire jumpers, and are removed by
cutting them. Resoldering the JU jumpers is not recommended. If this is
required, or if a function is to be changed (from volts to current), Simpson
recommends returning the Falcon to the factory or an Authorized Service
Center. After moving the jumpers to the desired location, put the Falcon
back together and install in your panel, or proceed to calibration.

Display Scaling
The Falcon can be easily scaled for a broad range of engineering units.
The meter may be scaled up to two times, or down to 1/5 the value of
the input.
1) Remove the front bezel with a small screwdriver.
2) Apply the full scale input to the meter.
3) Adjust the potentiometer VR101 located on the right side the display
board to the desired scaled value.
4) Replace the bezel carefully. A card of labels is provided for alternative
engineering units, such as percent.

Calibration
The following procedure requires opening the unit and removing the top cover
with the power ON. Use an insulated screwdriver and extreme caution when
making these adjustments. It is advisable to have an Authorized Service Center
perform this operation, or return the Falcon to the factory.
The Falcon is calibrated at the factory per order. If you changed the
range and have moved the jumpers, your Falcon will need to be recalibrated.
1) Remove the bezel with a small screwdriver.
2) Short input terminals #1 and #2 (IN HI and IN LO) and adjust potentiometer RV1 on AC Input card until display reads 0±1 count.
3) Apply an input signal to terminals #1 and #2, and adjust potentiometer VR101 until the display indicates the value of the signal. See
diagram in Display Scaling.

Application Example
A plant manager needs to monitor the current
draw of two machines from one AC power
source. The first machine is rated at 200mA,
and the second machine is rated at 75 amps.
The first machine can be monitored with a
Falcon 200 ACmA meter. The meter is installed
in series between the source and the load. No
additional scaling of the input is required.
The second machine requires a 75/5 amp
Donut Current Transformer and a Falcon 5AC
amp meter.
This meter need to be scale before it is
installed in the panel. A 5 AC amp signal
(equivalent to the full strenght signal from the
Donut Transformer) must be applied to the
Falcons’s IN HI & IN LO. Change the decimal
pointto199.9 by connecting the supplied

and remove the signal.

enable the Falcon to monitor AC
current up to 1999 amps. The
Donut (also known as a “Toroid”)
is placed around one of the legs
of the device being monitored,
and emits up to a 5 amp signal. The Falcon can be scaled
