NOTICE
Please read all the operation manual before operating the set and keep this manual for further
reference.
Installation of MAM—KY** compressor controller can be performed only by professional technicians.
Installation position shall be considered carefully in order to ensure good ventilation and reduce
electromagnetic interference.
Wiring shall be performed respectively according to regulations for heavy and weak current to reduce
electromagnetic interference.
RC snubber must be connected to the two terminals of coil (such as AC contactor ,valve, etc),which
are controlled by relay output.
Port connection shall be inspected carefully before power on.
Correct ground connection (the third ground)can help increase product capacity of resisting signal
interference.
Set rated current of motor: the max current of motor/1.2

Customer password or factory password is required to set auto start-stop function in customer parameter.
Customer can set “disable” or “enable” for “start” or “stop”. When auto start and stop are all set enable, and
the start and stop time is coming, controller will prompt massage and start 20S count down. After 20S passed,
start and stop command are activated. customer can press “cancel this operation” if the count down is more
than 5S to cancel this set.”。
