OVERVIEW
The KindHeart Model 4101 Mobile Simulation Controller, Generation 2 (MSC-Gen2) is a unit designed
for connection to KindHeart Simulators. The unit is designed, in conjunction with the connected
simulator, to replicate a heart beating 78 times per minute. This is achieved by means of a bellows style
air pump that is driven by a positioning style stepper motor drive system.
The stepper motor drive can actuate the bellows air pump to varying amounts, depending on the signal
it receives from a potentiometer, allowing the user to vary the amount of air delivered each cycle. A
speaker signals each heartbeat with a tone that represents a 98% oxygen level. The audible volume of
the speaker can be adjusted via a volume knob on the unit.
Internal pressure and vacuum relief valves prevent damage to the unit and individuals in case of line
blockage or failure. A liquid trap (packed as an accessory) is used to capture any liquid that may return
through the line to the simulator in case of failure.
PROPER USE
KindHeart Model 4101 is intended for use ONLY with the following KindHeart products:
KindHeart Thoracic Tissue Cassette
Products may be developed in the future which are appropriate for use.
UNPACKING
The unit, when received, contains multiple pieces contained within a shipping style mobile case.
There are also certain accessories
listed within this manual, that may
be shipped separately and are not
meant for storage and shipping
within this unit.
When you are ready to unpack this
unit, place the shipping case on a
flat surface with the wheels towards
the floor. It is best for this
procedure to take place on the
floor, or a low-rise platform as the
main unit is heavy and picking from
a low position with assist with a
proper lifting technique.
Opening the case is achieved by
unlatching the six latches located
around the perimeter of the unit.
Once opened, verify that all components are present and undamaged.

SET UP
The MSC unit is designed for use either within the shipping case or removed from the shipping
case. If it is being used within the shipping case, the case should be placed on a flat level surface
prior to set-up.
If this unit will be used while remaining in the shipping case, the top lid of the
case MUST BE LEFT OPEN during the run. Failure to do so will result in excess
heat build-up and could result in unit failure or fire.
If the unit will be used external to the shipping case, remove the unit by opening the shipping case
on the ground and remove the unit by grasping the handle on the top and lifting straight up. The
unit weight is 16.5kg (36lbs.), so care should be taken to use proper lifting technique during this
procedure.
Place the unit, feet down, on a flat level surface at least 50mm (2”) in from each edge. Ensure the
unit is stable and does not rock. If it does, a different surface should be utilized as stability is
important to maintain unit safety.
Whether left in the case, or removed from the case, the series of operations that follow are
identical and should be followed to ensure safety.
1) Remove the liquid trap from the shipping case and install into the unit as shown below.
2) Install the “Y” splitter into the liquid trap as shown below.
3) Install the air line into the “Y” splitter. If only one simulator is to be utilized, the air line
must be hooked into the connector labeled “1”. If this air line is hooked up incorrectly,
failure of the simulator to be properly animated will result. Connector “2” should be used
only if a second air line is used to connect a second simulator.
4) Connect the air line to the simulator as specified in the instructions for the specific
simulator
5) Installation of an IV pole (accessory not contained within shipping case) is accomplished by
extending the pole to the desired height and inserting it into the IV pole socket as shown
below.
6) Hook-up any liquid lines to the simulator as specified in the instructions for the simulator
7) Remove the power supply and power cord from the shipping case. Insert the power cord
into the power supply. If a different power cord is required based on country or local
requirements, any power cord with 18 gage wire or larger, an IEC320-C7 connector, and
required approvals can be utilized.
8) Plug the DC jack of the power supply into the DC connector of the MSC Gen2 unit. This
connector must be screwed down to get proper connection. Failure to do so will result in
intermittent, improper, or failure of function
9) Verify all air, liquid and electrical connections as described above are secure and correct,
then you can move to the START UP section.

START UP
Prior to start-up, make sure all items in the set-up section have been executed. One important fact
that should be observed any
time the unit is being
started, is to make sure the
unit is in an “off” state
before plugging the power
supply into the wall outlet.
To do this, both the “Power”
and “Pump” switch should
be in the “off” state. These
are off if the button is flush
with the top of the bezel.
Pressing the button will
toggle the button between
“on” and “off”. Make sure
that both are “off”. The
“Pump Volume” control
knob should be turned all
the way down
(counterclockwise). It is
suggested that the “Speaker
Volume” be turned all the
way down (counterclockwise). This will disable the speaker during start-up.
At this point, the power supply can be plugged into the wall. A blue light on the power supply
should illuminate, indicating that the power supply is properly functioning and supplying power to
the unit. During this operation, nothing should happen on the unit, as power should be isolated
from the unit by the “Power” button.
Press the “Power” button to the “on” position. The button should illuminate, indicating that power
is being supplied to the internal circuitry. Within a few seconds of pressing this button, the
stepper motor should begin a “homing” cycle. Slight noise and vibration should be heard during
this. When this routine has been completed, the “Pump Ready” light should illuminate. This
indicates that the stepper motor has properly started and is ready for operation.
At this point, the unit is ready for operation. When the operator is ready to start the pump, the
“Pump” button should be pressed. The button will illuminate, indicating that the pump is
operating. Once operating, the “Pump Volume” control knob can be adjusted up or down to set
the air volume being moved. Adjustment of the volume should be done slowly as this adjustment
updates the actual volume approximately 1 second after the adjustment.
While in operation, the speaker volume can be adjusted up or down by turning the “Speaker
Volume” knob.

OPERATION
During operation, the pump can be stopped by pressing the “Pump” button. This will stop the
stepper motor and the “Pump” button light will turn off. If the air and liquid connections remain
unchanged, the pump can be started again without the need for adjustment of the “Pump Volume”
or “Speaker Volume” knob. If air and/or liquid connection changes are required, the pump should
be completely shut down, and the Set-Up procedure should be repeated.
SHUT DOWN
At the end of operation, or at a point where an air and/or liquid change is required, the following
procedures should be followed:
1) Turn both the “Pump” and “Power” buttons to the “off” position.
2) Unplug the Power Supply from the wall outlet.
3) Remove the DC power jack from the DC power socket by unscrewing the jack and
removing.
a. At this point you can perform an air and/or liquid change. Resume start-up after
this change from Step 8 of the Start-Up section
4) Remove the power cord from the power supply, stow both in the correct position of the
shipping case.
5) Remove the liquid lines from the IV pole (if used) and remove the IV pole and collapse.
Place the IV pole in its proper container or position. This is not accommodated within the
shipping case.
6) Remove the air lines from the “Y” fitting if used, and the “Y” fitting from the liquid trap.
Upon inspection of the lines and “Y”, determine if any liquid has moved into the parts. If
liquid is present, these must be cleaned prior to storage. Stow the air line and “Y’ fitting in
the proper position.
7) Remove the liquid trap. If any liquid is present, proper cleaning is required prior to
storage. Stow the liquid trap in the proper position.
8) Wipe down the outside of the unit with 70% or greater isopropyl alcohol and a lint-free
towel. Make sure no obstructions are present in the heat vents on the front and back of
the unit. Make sure all debris has been removed from any surface of the unit or within the
air connection well.
9) If the main unit has been exposed to liquid of any type, follow the steps in the Cleaning
section before storage of the unit.
10) Stow the MSC unit within the storage case.
11) Verify all components in the storage case are properly seated and secure. Close and secure
the lid of the storage case.

CLEANING
All surfaces of the main unit and all accessories should be cleaned utilizing 70% or greater
isopropyl alcohol. This should be done by wetting a lint-free towel with the alcohol and then
wiping the parts to be cleaned. Cleaner should never be directly sprayed onto the main MSC unit.
If liquid has gotten in the air lines or “Y” fitting, it should be cleaned by plugging the end of the
line with your finger, and then pouring some alcohol in the line. After the liquid has been
dissolved, the alcohol can be released and disposed of. Air dry the lines prior to storage.
If liquid has entered the liquid trap, the liquid trap can be cleaned by unscrewing the clear bowl
from the black body. Remove the liquid and clean the liquid trap with alcohol and a lint-free towel.
Dry the components, then re-assembly and place in storage.
If liquid has entered the main MSC unit itself, it is imperative the unit is stopped unplugged
immediately. If the liquid that entered is not volatile and the amount is greater than a 5 ml (1 tsp),
the unit should be returned for servicing. If less than 5ml of non-volatile fluid entered, then the
unit should be put in front of a fan blowing directly on it for no less than 100 hours.
If the liquid that entered is volatile (alcohol or other), then the unit should be placed in an area
with a fan blowing on it. The amount of time the unit should be left in this condition is dependent
upon the amount of liquid that has entered. If 5 ml or less, the unit should be left in this condition
for 4 hours. If between 5ml and 20ml, the unit should remain for 24 hours. If more than 20ml
entered, then the unit should be returned for servicing.
If fluid has entered the unit, operation continued as it was un-noticed, and the machine started to
malfunction, send the unit back for service. If the machine did not show any signs of
malfunctioning and the belief is that the amount of fluid was low, then place the unit in front of a
fan for no less than 100 hours before using again. If any uncertainty remains, the unit should be
returned for servicing.
