Problem and LED color
Description
Main transistor or driver
damage
Red and yellow blinking
alternately
Main transistor or driver is damaged. Unit needs to be sent back for
repair.
Battery voltage sensing
malfunction
Red and white blinking
alternately
Battery detection system is malfunctioning. The unit needs to be sent
back for repair.
Other known problems:
Problem
Cause
Solution
Replica fires a
2-round burst
in semi-auto
mode.
Motor and battery are too strong
for the main spring, which causes
overspin.
Enable AB or precocking.
Too high precocking level.
Set precocking to a lower level.
Trigger mechanism malfunction.
Check the cut-off lever and contacts, replace
if needed.
Replica does
not shoot; the
unit does not
emit any light
or sound.
Incompatible T-Deans battery
connector.
T-deans plugs and sockets from various
manufacturers may sometimes not work
together reliably. Although the plug may
seem to fit the socket nicely, the conductive
surfaces may not contact each other, cutting
the power off. In that case try with another
battery, most preferably with a T-deans
socket made by a different manufacturer.
Battery
and/or the
motor heat up
very much.
The battery has a too low capacity
(mAh) and/or the
“C” parameter.
Use a battery with higher capacity and/or
the
“C” parameter.
The motor is too weak.
Use a stronger motor, possibly with
neodymium magnets.
Increased motor load caused by
excessive friction, for example
caused by:
- improper shimming,
- motor positioned askew in the
pistol grip.
Remove the cause of the friction.
Motor beeps
from time to
time
Li-Po alarm has activated
Replace the
battery (if you’re not using a Li
-
Po or Li-Ion, disable the Li-Po alarm).
The same
battery
and/or motor
did not heat
up earlier.
Low-resistance MOSFET transistor and wiring used in Perun ETU++ provide
resistance much lower than mechanical contacts and some other MOSFET circuits.
According to Ohm’s law, that allows more current to be drawn from the battery
and directed to the motor. This makes the trigger response and rate of fire faster,
but a higher current draw also leads to increased heating of electronic elements.
This may become too demanding for the previous battery and/or motor and a
need to change to new ones may arise.
Attention!
