Electric subsystem
All the major systems are protected by fuses.
The fuses are located:
• on the mains power socket (See “Replacing the mains socket fuse” page
3-2);
• at input of mains transformer, marked F1 on the power PCB (See
“Replacing the power PCB fuses” page 3 - 5);
• at output of solid-state relay of the compressor, marked F2 on the power
PCB (See “Replacing the power PCB fuses” page 3 - 5).
The I-mmersion™control circuit constitutes the heart of the system:
• It automatically compensates for patient/bed position changes and
supports the patient at the optimal pressure.
• It automatically corrects the pressure in the bladders.
• It automatically compensates most variations due to external parameters.
Control unit
The control unit contains a rechargeable battery on the power PCB. It powers
the mains supply alarm in the event of a power cut.
The control unit panel is the main means of controlling the Primo™. It
contains the minimal functions and provides the user with feedback on the
status of the device and any malfunctions that may occur.

Indicators / alarms
(see figure 1-7 page 1-8)
A - Malfunction alarm:
the audio alarm sounds and the yellow visual alarm lights up after
about 10 minutes, when:
• the sensor is faulty;
• the sensor is disconnected;
• CPR mode is active;
• the mattress is damaged (tears, leaks, damaged couplings, etc).
The audio alarm sounds and the yellow visual alarm lights up after
about 20 minutes, when:
• the pressure in the mattress drops below 4″H2O +/- 0.8"H2O
(10 mbar +/- 2 mbar);
B - Mains power fault alarm:
The audio alarm sounds and the yellow visual alarm lights up
immediately, in the event of:
• electric power cut;
• damaged power supply cable;
• accidental disconnection of the power supply cable;
• fuse on the mains power supply socket, or fuse F1 on the power
supply PCB damaged;
• transport.
C - On/Off indicator light:
the green light comes on when the control unit is on.
D - Inflation indicator:
the green light flashes for 5 minutes as the mattress is inflated.
I-mmersion™sensor
The I-mmersion™sensor, which has its own PCB, uses resistive variation due
to the applied force. When the patient's sacrum presses against the mattress,
this pressure is transmitted to the sensor as a force. The variation in the
resistivity of the sensor is measured. A signal is then sent to the control unit to
deflate or inflate the mattress, until the pressure in the mattress is equal to the
pressure of the sensor.
By calibrating the balance of the I-mmersion™sensor, the servo-control
always optimizes the support of the patient, irrespective of their weight or
position (within the limits specified in page 1-5).
CPR valve
In CPR mode, the regulation functions normally, the compressor remains
under control, but not the leak solenoid.
The yellow visual alarm lights up
to indicate that that the pressure is low
. A low-priority alarm sounds
immediately, intermittently and at a moderate volume.
Pneumatic subsystem
The air is drawn into the control unit through the air filter. The air filter limits
the ingress of dust, which could clog the pneumatic circuit. The air then flows
into the compressor inlet.
When the air leaves the compressor, it is distributed between the bladders in
the mattress, the mattress/seat cushion coupling and the pressure relief valve
on the electric power supply PCB.
Two-tier mattress
The mattress is made up of two levels:
• a therapeutic mattress;
• a foam sub-mattress, which includes the sensor unit, and a lower cover
that includes the sensor.
The therapeutic mattress is a single piece made up of a series of 15 airtight
bladders. The air pressure in these bladders is the same as the pressure in the
sensor in the lower cover.
The I-mmersion™detector is located beneath the sacrum zone of the
therapeutic mattress.

The diagnosis tester is used to:
• measure the 12 V DC supply voltage of the I-mmersion sensor;
• check the inflation signal sent by the I-mmersion sensor;
• check the deflation signal sent by the I-mmersion sensor;
• check the temporary inflation signal sent by the power PCB when the
seat cushion inflate function is activated.

Getting Started
Start all of the procedures in this Chapter at step 1. Follow the indicated order.
Each step assumes that the preceding steps have been correctly completed.
Each step corresponds to the normal operation of the product. Please answer
"Yes" or "No" to the question. If more than one component is listed, replace
them in the given order, and re-install the original component that was found
to be OK.
1. To begin gathering information about the problem, start with the initial
actions.
2. Perform functional checks to locate/identify a problem and check the
repair after every corrective action (e.g., replacing or adjusting a part,
installing a cable).
3. To verify the repair, perform the final actions after the function
checks.
If the troubleshooting procedures do not isolate the problem, call your
national Hill-Rom Technical Support (see back cover) for assistance.
NOTE:
The purpose of the proposed troubleshooting method is to limit as much as
possible the number of spare parts required and costs when analyzing the
failure.

Preventive maintenance instructions
Refer to the “Preventive maintenance and Pre-Delivery Inspection Instructions” (P/N: 172559).
The frequency of inspections must be adapted to the general condition of the product and its use, for example, if the overlay is used by heavy patients. It is the
responsibility of the facility to implement a preventive maintenance program for the mattress functions under its conditions of use.
The mattress and accessories should be inspected at least once a year to keep them in good condition and working properly.
Every three years, it is preferable to ask Hill-Rom After-Sales Service or a Hill-Rom approved supplier to inspect the device in order to keep it in safe and good
working order over time. Depending on the maintenance operations and observations, the date of the next inspection must be recommended every time the bed is
serviced.
In order to benefit from optimal and rapid service when calling Hill-Rom about your Primo™, provide the serial number of the system about which you are calling.
