OVERLOAD PROTECTION
The motor and function outputs of the ZIMO large-scale decoders are designed with large re-
serve capacities and are additionally protected against over-currents and short circuits. Automat-
ic shutoff will occur in case of overload followed by automatic reboot attempts (which often re-
sults in flashing lights).
These safety precautions do not mean that the decoder is indestructible. Please pay attention to the
following:
Faulty decoder hook-up (mixed up connection wires) and improper electric connections between the motor
terminal and chassis are not always recognized and can lead to output driver damage or even total destruction
of the receiver.
Unsuitable or defective motors (e.g. with short-circuited turns or collectors) are not always recognizable by
their high consumption of electricity (only peaks may register) and can lead to decoder damage, sometimes
long term effects can cause output driver defects.
The decoders output drivers (for the motor and function outputs) are not only at risk through over-current but
also through voltage spikes as they are delivered from the motor and other inductive consumers. Depend-
ing on track voltage, such spikes can reach several hundred volts and are absorbed by special protection cir-
cuits inside the decoder. The capacity and speed of such elements is limited and so unnecessarily high track
voltage should not be used. Never use a higher voltage than recommended for a particular vehicle. Only in ex-
ceptional cases should the ZIMO adjustable range (up to 24 V) be utilized.
THERMAL PROTECTION
All ZIMO decoders come equipped with a sensor that detects the actual temperature. Once the
maximum permissible value (ca. 100 oC on the circuit board) has been reached, power to the
motor will be shut off. Rapidly flashing headlights (at ca. 10 Hz) will signal that a shut-off has oc-
curred. Motor operation will resume automatically after a drop in temperature of about 20 oC, typ-
ically after 30 to 60 sec.
SOFTWARE UPDATE
ZIMCO decodes are designed so that software updates can be completed by the user. This re-
quires a device with an update function (ZIMO decoder update module MXDECUP, or MXULF,
or “central system cab“ MX31ZL/MX32ZL, or command station MX10).The update itself is car-
ried out via a USB stick (MXULF, MX31ZL, MX32ZL, MX10) or via a computer with the “ZIMO
Sound Programmer” ZSP software or “ZIMO Rail Center” ZIRC software.
There is no need to remove the decoder; the locomotive does not need to be opened; it can be
placed onto the update-track (connected to the update-device) without any changes and can
then be updated via a USB stick or a computer.
Note: Locomotive accessories that are directly connected to a track (not controlled by the decoder) may inter-
fere with the update; in that case the locomotive will have to be opened and removed from the track.
