flickering of the lamp attached to the LC1 output
indicates TMCC signal loss. When the TMCC signal is
restored, the Mini Commander will reset and resume operation.
in Configuration Mode, the lamp attached to LC1 output will flash slowly
(about once per second).This occurs during Soft Set or when setting the
“Cfg/Run” switch to Configuration.
When no lamp is connected to LC1, simply press
the SET key a few additional times to be sure Soft Set was
polarity is important when connecting to the LC1 and LC2
LED fails to light, try reversing the LED and series diode.
No load resistors are needed to use LEDs.
Mini Commander has built in snubbers on each output.Each snubber is a0.1uf / 100v capacitor.In some high inductance applications, this will not
a high inductance load is attached, a 1.0uf / 50 v NPO
capacitor may be added across the load. The need for
the additional 1.0uf capacitor is indicated when the
attached coil motor cannot be turned off as
expected. For example: the Dump Car needs the
capacitor, and is indicated by the dump operation continuing
after the CAB-1 key is released.
test for overheating of the Mini Commander after installation;
excessive back EMF or excessive current will cause the Mini
Commander to heat up.
Be careful, things heat up pretty
fast and get very hot when there is a problem. Run for about 5
seconds, check. Run for a couple minutes, and check
again. Power off when checking for overheating.
You do not need to be in physical contact to feel
overheating. Use caution!
no circumstances configure a vibration motor above 7+ BOOST (14v).Check
for overheating on the Mini commander card after installation on a
After running a little while, remove
power and check for heat on the components, drivers and
power supply. In normal operation nothing on the Mini
Commander gets more than warm; but when things go wrong,
components get very hot. Use caution!
connect to AC motors with field coils, only use DC can-style motors
on the HC1 or 2 output. Connection of an AC motor with field
coils can be done by using a relay, but you lose any speed control
options from the configuration process.
