This service manual describes all functions and configurations of only the device mentioned
in this manual. Differences may exist between the description in this manual and the actual
situation of the device, especially after the device is modified. In this case, corresponding
maintenance information may be required for maintenance. Therefore, this service manual may be
used together with some follow-up complementary information for device maintenance.
MEDCAPTAIN will complement the relevant information in time according to the actual
situation of the device modification.
Service personnel should also refer to the Operation Manual.
1.3 Technical Safety Checks (TSC)
The user is obliged to perform or to have performed the Technical Safety Checks on those medical
products for which these checks have been prescribed by the manufacturer and to carry them out
according to the indications of the manufacturer as well as the generally approved technical
standards while adhering to the periods stated. MEDCAPTAIN also recommends training on the
Technical Safety Checks, or to perform at least the steps indicated in the current
version of the manual, as:
- The TSC requires that the instructions in the manuals are observed
- The manuals are a reference for measurements
- Depending on the unit type, the Service Program must be called which may lead to a dangerous
unit condition in case of inappropriate operation. Furthermore, a special service connector may be
necessary.
1.4 Device Maintenance and Inspection
The power supply of this device may reach up to 100-240V. Maintenance in violation of the

conditions. Do not touch PCBA or semiconductors by hand without any protective measure.
Do not touch the display by using sharp objects. Otherwise, the display may be damaged.
Do not autoclave the infusion pump.
Before using the internal battery, check the battery to ensure that sufficient power is available.
Recharge the battery if required.
Liquid intrusion into the AC power socket or nurse call socket may cause short-circuit.
Before connecting the power cable, check if the connecting parts are dry. If liquid has spilled
onto the infusion pump, clean the pump with a dry cloth and then perform an inspection and
maintenance.
Use the maintenance parts and accessories provided by MEDCAPTAIN for replacement and
maintenance.
Do not maintain or use the infusion pump in a flammable environment.
High-frequency surgical equipment, mobile phones, wireless devices, and defibrillators may
cause interference on the infusion pump. Therefore, keep the infusion pump away from these
devices when using the pump.
After maintenance, perform a safety test and clean the pump according to this manual.

Notes:
The maximum voltage of the AC/DC power board may reach up to about 400 V. The workbench must be
insulated to avoid touch of the high-voltage circuit part. High voltage may cause electric shock and
personal injury.
When performing a test with a multimeter or oscilloscope, note that the test probe must not short-circuit the
live part on the circuit board to avoid damage of the circuit board.
4.3 Main Control Board
a. Circuit description:
The HP-60 main board integrates the power system, main control system, communication circuit and
interface, motor drive control circuit, air bubble detection circuit, and fluid side/patient side occlusion pressure
detection circuit. The specific functions are as follows:
(1) Power system: The power system consists of the battery and charging circuit, voltage conversion
circuit, and backup alarm circuit. The battery and charging circuit adopts the BQ24125 charging
scheme of TI. By default, quick charging mode is selected in power-off state and standard charging
mode is selected in working state. Charging is supported when AC input or DC input is available.
In case of AC input, the battery can be charged to 90% of the total capacity in 6 hours and fully
charged in 8 hours. The voltage conversion circuit converts the 15V power supply output by
AC-DC, battery power supply, or external DC power supply into the voltage required by the system.
The voltage reduction circuit converts the power supply into 5V and 3.3V to provide the CPU and
system with proper power supply. The voltage increase circuit converts the power supply into 24V
for motor driving.
(2) Main control system: 3-CPU design, independent drive control, and dual-channel monitoring.
STM32F429IIT6 (M4 for short) is used for display driving, Ethernet drive control, and wireless
module communication. STM32F030RCT6 (M0 for short) is used for control of motor drive chip,
control of audible and visual alarm, and signal detection. STM32F030C8T6 (M0S for short) is used
for signal detection and control of motor power supply.
(3) Interface circuit: USB2.0 interface implements the RS232 interface function. In addition, it can
implement communication with the HP-80 infusion workstation and connection to the barcode
scanner for scanning of patient information, for example, scanning of medical record number and
