Rated at 250VAC / 6A and 30VDC / 3A under standard use categories (AC15, DC13).
| Symptom | Possible Cause(s) | Corrective Action | | :--- | :--- | :--- | | | - One or more phases missing at input. - Loose connection on L1, L2, or L3 terminal. | Check incoming power with a multimeter. Ensure all three phases are present and correctly terminated at the controller. | | "逆相" (Reverse Phase) LED is ON. | - The phase sequence of the L1, L2, L3 supply is incorrect. | Swap any two of the three phase input wires at the controller's L1, L2, or L3 terminal. For example, swap L1 and L3. | | "过压" or "欠压" LED is ON. | - Supply voltage is outside the preset range. - Voltage threshold may be set incorrectly. | Measure the incoming voltage. Verify voltage is within the unit's rated range. Consult manufacturer documentation for adjusting set points. | | "缺相" (Phase Loss) LED is ON. | - One of the three phases is completely missing. - A severe voltage imbalance (>10%-20%) exists. - Loose connection or faulty fuse upstream. | Check all three supply fuses/breakers. Measure each phase-to-phase voltage. Tighten all connections. A significant imbalance indicates a problem with the supply or transformer. | | Relay chatters or trips randomly for a few seconds. | - Momentary voltage sags or spikes. - Loose wiring in the control circuit. | Check all wiring for tightness. The 7V hysteresis helps prevent this, but if the supply is very noisy, consult the manufacturer for application guidance. | | Equipment starts but then trips immediately. | - The control circuit is wired to the NO contact. - A phase loss or imbalance condition exists. | Verify the control circuit is wired through the NC (Normally Closed) relay contact. Check the "缺相" and "逆相" indicators. |
Protecting massive scroll compressors from reverse rotation.

🚨 This product should be installed on the power side of the network. It must not be installed on the output side of a variable frequency drive (VFD). If you'd like, I can: Find retailers where you can purchase a replacement.
Verify that the cooling fins run vertically to optimize natural airflow.
: Check the tightness of all electrical connections, as thermal cycling can cause screws to loosen over time.
Features two normally open ( NO ) and two normally closed ( NC ) electrically inseparable contacts.
Clips the peak power delivered to the load when the control signal reaches 100% (e.g., 20mA or 10V). Turn counter-clockwise to protect undersized loads from over-voltage.
