Notice
Please read all the operation manual before operating the set and keep this manual for further reference.
Installation of MAM—8** compressor controller can be performed only by professional technicians.
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.
PARAMETER is not allowed to be modified in running and stop delay status. Only user
parameter is allowed to be changed at running status

1.6 Operating Authorization and Password
Controller provides multiple passwords and access management. According to different levels of passwords,
controller provides different levels of operating authorization. Details are as following:
Customer Password: factory set ____________

Factory Password: fixed ____________
Permissions: Allows user to modify all Parameter
2 Controller Function and Technical Parameter
 Phase sequence protection:
When compressor is at stop mode an detects open phase, response time <2ms
 Open phase protection
When any phase opens, the response time equals to set time: This fuinction is not activated when OPEN PHASE
PROTECTION time iss et over 20s
 Motor protection: This control unit has the following 5 basic protection functions to the motor and fan.
o Rotor lock protection: After the starting oft he motor, if the working current reaches 4 or 8 times oft he set
value, the protection activates. The activate time is less than 0,2s.
o Short.circuit protection: If the detected current reaches 8times or more above the set value, the protection
activates, the activate time is less then 0,2s
o Lack phase protection: Any oft the phase lack, the protection activates and theactivate time ist he setting
time
o Unbalance protection: The current difference between any of the two phases reaches the percentage of the
setting value, the protection activates and the activate time is less than 5s.
o Protection features of overload, please see following table for your reference. Multiple＝Iactual／Iset ,
response time is shown in following table according to overload multiples from 1.2 times an 3.0times.

5 Controller Protection
5.1 Motor Protection
MAM-200 compressor controller provides short circuit, block, overload, lack phase and unbalance protection on
motor.
Electronic
Failure Failure Display Reasons
Short circuit Display “MOTOR / FAN OVERLOAD” Short circuit or wrong current set
Current block Display “MOTOR / FAN BLOCK” Overload, bearing wear off or other mechanical failures
Overload Display “MOTOR / FAN OVERLOAD” Overload, bearing wear off or other mechanical failures
Lack phase Display “MOTOR / FAN LACK PHASE” Power supply, contactor and open phase of motor
Unbalance Display “MOTOR / FAN UNBALANCE” Poor contact of contactor, inside open-loop of motor
5.2 Protection of Air Temperature High
When AIR T is above the STOP DISC T, the controller will alarm and stop the machine.
This fault displays DISC T HIGH
5.3 Protection of Air Compressor Reversal
When the phase sequence of the power connected to the air compressor is not conforming to the set of the
controller, the local failure displays “Wrong phase sequence” and as a result the controller cannot start the motor.
It is needed to check and alternate any two of the phase sequence and investigate the motor rotation direction.
5.4 Protection of Air Pressure High
When the AIR P is above the STOP P, the controller will send out the alarm to shut down the machine and this
fault displays AIR P HIGH
5.5 Protection of Sensor Failure
When the cable of the pressure sensor or the temperature sensor is broken, the controller will alarm and stop the
machine and the local failure displays “** sensor failure”.
5.6 Interlock Protection
The Motor is running and the air exhaust temperature reaches the fan starting temperature but the fan does not
run, the controller alarm, the local failure displays “FAN is stopped”.
