Problems With The Power Supply; Problems With External Input Devices - tams elektronik mc2 EasyControl Digital System Silver Edition Manual

The power supply unit switches off and then on again after a while.

Possible cause: overload à Reduce the number of connected additional devices and/or the
power consumption in the booster circuit of the integrated booster. As soon as the overload
is eliminated, the power supply unit is automatically switched on again.

Possible cause: Overvoltage à As soon as the input voltage of the power supply unit is
within the permissible range again, it is automatically switched on again.

Possible cause: Overheating à Check whether the power supply unit has sufficient distance
to surrounding surfaces and/or is exposed to direct sunlight. Ensure an unhindered
exchange of air. As soon as the power supply unit has cooled down, it is automatically
switched on again.

8.3. Problems with the power supply

The input voltage is less than 22 V.
Indication on the display: "Pf" or "LP" | RGB LEDs: red
! Warning:
If the display shows "Pf" (Power Fail) or "LP" (Low Power), disconnect the central unit from
the power supply immediately. There are incalculable risks in continuing to operate the
system!

Possible cause: Overload of the power supply unit. 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.

Possible cause: defect at the power supply unit. à Check the supply voltage of the mc² in
the menu item "System / Info". If it is below 22 V despite low current consumption in the
booster circuit of the integrated booster and a low number of connected external digital
devices, the power supply unit is probably defective. Send it in for checking.

8.4. Problems with external input devices

The decoders do not respond to digital commands entered at a digital central unit on the
Sniffer.

Possible cause: The central unit on the Sniffer is not set to DCC or Motorola as the format
for track output. However, the mc² cannot evaluate digital commands in different formats.
à Change the setting at the connected command station.
A locomotive with mfx decoder cannot be controlled with an input device connected to the
CAN interface of the mc².

Possible cause: The mc² cannot control mfx decoders directly. à You must first assign an
address for the m3 format to the decoder (menu item "Operation / Programming").
