Connection Wiring for EDAN F Series

EDAN F200 F300 F2 F3 Fetal Monitor Power Board Connection Wiring 01.13.114337

► Brief Description

The Edan F series is a highly reliable and accurate monitoring device. It features a modular design, with the power board converting external AC power into the DC voltage required by the internal modules and providing overvoltage, overcurrent, and short-circuit protection. Although the wiring on this power board is a small part, it plays a crucial role in the device. It is an indispensable component of this monitor; please contact us anytime for any needs.

► Troubleshooting

If the device fails to power on or shuts down unexpectedly, the problem may lie in the wiring connections.

● Symptom: No power at all

1. Check: Confirm the AC input voltage.

2. Check: Check the fuses on the power board.

3. Check: Ensure the DC output pins are supplying the correct voltage.

● Symptom: Intermittent power interruptions

1. Check: With the device powered on, gently shake the cables near the connectors. If the device shuts off, the connector pins may be loose or oxidized.

2. Check: Check the solder joints of the connecting wires on the power board for cold solder joints.

► Wiring Step

1. Visual Inspection: Check for burnt wires, loose connections, or corroded pins.

2. Connector Alignment: Ensure the connector's clips align with the socket on the motherboard.

3. Secure Insertion: Press firmly on the connector until it clicks into place. Do not force insertion if the connector cannot be inserted.

4. Stress Relief: Ensure cable routing is correct and secure, avoiding direct tension on solder joints.

► Precautions

Before performing any internal checks or rewiring, please follow these safety procedures:

● Disconnect power: Before opening the casing, always unplug the device from the AC power outlet and remove the internal battery.

● Discharge capacitors: High-voltage capacitors on the power board may retain residual charge. Use appropriate tools to safely discharge this charge.

● Anti-static measures: Wear an anti-static wrist strap to prevent electrostatic discharge (ESD) damage to sensitive components.

● Qualified personnel only: This operation should only be performed by trained professionals.
