Switch Board for EDAN F Series Monitor

Switch Board 21.53.114408 with Cable 01.13.106460 for EDAN F Series (F2 F3 F200 F300) Fetal Monitor

► Brief Description

The EDAN F Series (F2, F3, F200, F300) is a widely used device in prenatal care. Its control panel's switchboard is not only the core of the human-machine interface but also a key component ensuring accurate data acquisition. The EDAN F Series monitor employs a modular design; this switchboard, located on the front panel, has power control functionality. It not only handles simple circuit switching but also sends logic signals to the main board.

► Features

The EDAN F Series (F2 F3 F200 F300) Fetal Monitor features a tactile button switch with a more compact design to meet the needs of portable monitoring. It has the following characteristics:

1. Operating Voltage: Low-voltage DC signal (typically 3.3V - 5V)

2. Contact Resistance: < 50mΩ, ensuring stable signal transmission

3. Mechanical Life: ≥ 50,000 presses, meeting medical-grade microswitch standards

4. Insulation Class: BF type with partial isolation, effectively preventing leakage current from affecting patient safety.

► Common Faults

After prolonged use of EDAN F series equipment, the switch board may experience the following typical faults:

1. Button malfunction or no response

● Possible Causes: Aging of conductive rubber, oxidation of PCB board contacts, or moisture.

● Troubleshooting Method: Use a multimeter to measure the continuity when the button is closed. If the resistance is infinite, the switch board assembly needs to be replaced.

2. Equipment cannot be shut down or automatically restarts

● Possible Causes: Power button stuck (physical damage) or power management chip signal interference.

● Solution: Check if the switch board cable is loose and confirm that the power button's rebound force is normal.

► Maintenance

To extend the lifespan of the EDAN F-series fetal monitor switchboard, the following maintenance procedures are recommended:

1. Regular Cleaning: Wipe the panel with 70% isopropanol or medical ethanol. Do not allow liquid to seep directly into the button gaps, as this may corrode the PCB circuitry.

2. Moisture Prevention: F-series devices are commonly used in high-humidity environments, such as delivery rooms. If the device is not used for extended periods, it should be powered on periodically to dissipate internal moisture and prevent oxidation of the switch contacts.

3. Cable Inspection: When disassembling the switchboard for maintenance, always check the cable (FFC) for creases or breaks, as these are common causes of poor contact.
