4.10 HP-60 Tube Detection Board
a. Circuit description:
(1) The tube detection board contains a Hall switch assembly, which is used to detect whether the pump
door is closed. The pump door contains a magnet. When the pump door approaches, the signal of the Hall
switch assembly changes. Whether the door is closed is judged by detecting signal changes.
(2) The fluid side occlusion pressure detection board contains an optical coupling circuit, which is used to
detect the infusion tube. When an infusion tube is installed, the light baffle shields the optical coupler,
indicating that an infusion tube is installed.

4.11 HP-60 Anti-Free-Flow Clamp Board
a. Circuit description:
The anti-free-flow clamp board contains an optical coupling circuit, which is used to detect the
anti-free-flow clamp signals of the simple dedicated infusion set. When the anti-free-flow clamp is installed,
the light baffle shields the optical coupler.

4.12 Stepper Motor
a.
HP-60 uses two types of stepper motor, that is, door opening motor and infusion motor. The door opening
motor connects to the main board J8 to control door opening and closing. The drive voltage of the infusion
motor is 24V, 2-phase drive.
