*) The short circuit protection is carried out for the total current of all outputs. Use the "soft start" option (i.e. CV #125 = 52) to prevent
cold-start problems of light bulbs (in-rush current interpreted as a short circuit, which leads to the output being turned off)!

Software Update:
ZIMO DCC decoders can be updated by the user. An update device such as the ZIMO decoder up-
date module MXDECUP, from 2011 MXULF, system-cab MX31ZL or command station MX10 is
required. The update process is carried out by a flash drive (MXULF, MX31ZL / MX10) or by a PC
with Windows operating system and the program ZIMO Firmware Flasher (in the bundle with ZSP).
The same hardware, but ZSP (software) is also used for uploading sound projects into ZIMO sound
decoders.
There is no need to remove the decoder or to open up the locomotive. Just set the locomotive on a
section of track connected to the update module and start the update with the computer or other
equipment mentioned above.
NOTE: Equipment inside the locomotive that is powered directly from the track (not through the de-
coder) can interfere with the update procedure. The same is valid for energy buffers that are in-
stalled without heeding the advice in the "Installation and wiring" chapter, section "Use of an external
energy source" (regarding a choke coil).
See the last chapter in this manual for more information on updating decoders or www.zimo.at!
Of course, SW updates can be done by ZIMO or your ZIMO dealer for a small fee.
Overload and Thermal Protection:
The motor and function outputs of ZIMO decoders are designed with lots of reserve capacities and
are additionally protected against excessive current draw and short circuits. Cut-outs are encoun-
tered if the decoder is overloaded.
Even though the decoder is well protected, it is not indestructible. Please pay attention to the following:
Wrong decoder contact, if, for instance, the motor leads have contact to track power or an overlooked connection
between the motor brushes and rail pick-ups is not always recognized by the overload protection circuit and could
lead to damage of the motor power amplifier or even a total destruction of the decoder.
Unfit or defective motors (e.g. shorted windings or commutator) are not always recognized by their high current
consumption, because these are often just short current spikes. So, they can lead to decoder damage including
damage to power amplifiers due to long-term exposure.
The power amplifiers of loco decoders (motor as well as function outputs) are not only at risk of overcurrent but al-
so voltage spikes, which are generated by motors and other inductive consumers. Depending on track voltage,
such spikes can reach several hundred volts and are absorbed by special protection circuits inside the decoder.
This is why the voltage shall not be too high, i.e. not higher than intended by the corresponding vehicle.
All ZIMO decoders are equipped with temperature sensors to measure their own operating temperature.
Power to the motor will be turned off once that temperature exceeds 100
rapidly, at about 5 Hz, to make this state visible to the operator. Motor control will resume automatically af-
0
ter a drop in temperature of about 20 C, typically in about 30 seconds.
