8. Checklist for troubleshooting

When delivered, your mc² has the password "Tams". If you have changed the password and
then forgotten it, you can display it on the web developer console of your browser. Click on
set (password) after opening, the password will then be displayed in the console. On the
Internet you can find instructions on how to get to the web developer console of your
browser.

8.1. Heat generation

Heating of the central unit and the power supply unit during operation is normal and harmless.
Under continuous full load, i.e. when the integrated booster supplies more than 6 A of current
for a longer period of time, the temperature can reach up to 75 °C. If a high temperature is
reached at low load, the mc² probably has a defect.
Warning:
!
If you notice severe overheating on the mc² and/or the power supply unit, disconnect the
central unit and the power supply unit from the supply voltage immediately. Fire hazard!
Send in the mc² and the power supply unit for testing.

8.2. Automatic safety shutdown

The mc² switches off the track voltage and indicates a short circuit.
Indication in the display: "SH" | RGB-LEDs: red and violet alternately

Possible cause: short circuit on the rails à Eliminate the short circuit.

Possible cause: exceeding the maximum permissible current in a booster circuit à Check
whether the maximum current for the booster(s) is set correctly (menu item "System /
Boosters"). à If the maximum current was set correctly, you must reduce the current
consumption in the booster circuit.

Possible cause: exceeding the maximum permissible total current (= 6.67 A). The reason is
usually a permanently high current consumption in the booster circuit of the integrated
booster with a simultaneously large number of external digital devices at the CAN, LocoNet,
EasyNet and/or BiDiB interface. à Reduce the current consumption. Supply the external
digital devices via an external power supply if possible.
The mc² switches off the track voltage and indicates overheating.
Indication in the display: "ot" | RGB-LEDs: yellow

Possible cause: overheating à Check whether the mc² has sufficient distance to
surrounding surfaces and/or is exposed to direct sunlight. Ensure unhindered air exchange.

Possible cause: Permanently high current consumption just below the maximum permissible
total current (= 6.67 A). The reason is usually a permanently high current consumption in
the booster circuit of the integrated booster with a simultaneous large number of external
digital devices at the CAN, LocoNet, EasyNet and/or BiDiB interface. à Reduce the current
consumption. If possible, supply the external digital devices via an external power supply.
