Check the 115/230 switches at the bottom of the control box — they must match your local power grid requirements.
The switches should only be changed when the equipment is powered off.
The power supplies have triggered their short-circuit protection mechanism due to one of the following failures: a Cytron board failure, a 5KP24CA diode failure, or a Mean Well LRS-350-24 power supply failure.
To diagnose the issue with the power modules, please follow these steps:
Step 1. Disconnect the motors:
Step 2. For the power modules where the green LED is not lit:
Disconnect the diode (#2 in the figure) → Does the green LED on the power supply turn on?
Yes → The issue is with this diode. Replace it with a 5KP24CA diode (it can be purchased from us or from local stores).
No → Proceed to Step 3.
Step 3. Disconnect the Cytron MD13S wire (#2 in the figure) → Does the green LED on the power supply turn on?
Yes → The issue is related to the Cytron MD13S (replace it; it can be purchased from us or from local stores).
No → Replace the LRS-350-24 power module (it can be purchased from us or from a local store).
If the steps above do not resolve the issue, the most likely cause is a broken wire between the motherboard and the power supply.
If no wiring damage is observed, the next step will be to check the motherboard.
If the motherboard is defective, all power supplies will stop working.
Please take a clear photo of the motherboard while the system is powered on and send it to us.
