Why does my Rotem Platinum PLUS Controller display many error messages?
- KKevin WarrenJul 27, 2025
The Rotem Controller may display many error messages because the I/O BUS (I2C) or the Switch BUS (I2C) is stuck. To resolve this: * Disconnect the bridge card between the CPU card and the switch bus. * Check if the LED on the alarm card is blinking. * If the LED is not blinking, the problem likely lies within one of the I/O cards. You'll need to identify the faulty card. * If the LED is blinking, a switch card or the switch bus itself is causing the I2C bus problem. You'll need to identify the faulty switch card.
