PANEL INDICATOR
Working status indicator: in start delay duration, start indicator will blink; in other working duration, the indicator will always light; in stop status, the indicator will extinguish.
Stop status indicator: in stop process, stop indicator will blink; in stop duration, the indicator will always light; in start status, the indicator will extinguish.
OPERATION
REMOTE START SEQUENCE
- When remote start signal is active, “Start Delay” timer is initiated;
- When start delay is over, preheat relay energizes (if configured), “Preheat delay” is initiated;
- After the above delay, the Fuel Relay is energized, and then one second later (if configured), the Start Relay is engaged and the Preheat Relay switch off. If genset fails to fire during this cranking attempt then the fuel relay and start relay are disengaged for the pre-set rest period; “Crank Rest Time” begins and wait for the next crank attempt (after the “Crank Rest Time” delay start for 3s, preheat and ETS start to output; after “Crank Rest Time” finished, ETS switch off, and after fuel output for 1s, preheat switch off);
- Should this start sequence continue beyond the set number of attempts, the fail to start indicator will be illuminated;
- In case of successful crank attempt, the “Safety On” timer is activated, allowing Low Oil Pressure Input and Under Pressure are inhibited. As soon as this delay is over, “start idle” delay is initiated (if configured);
- During “Start Idle” delay, under pressure alarm is inhibited. When this delay is over, “Warming Up” delay is initiated (if configured);
- After the “Warming Up” delay, genset will enter into Normal Running status.
REMOTE STOP SEQUENCE
- After remote start, when remote start signal is invalid, “Stop Delay” timer is initiated;
- Once this “stop delay” has expired, the “Cooling Delay” is then initiated;
- During “Stop Idle” Delay (if configured), idle relay is energized;
- “ETS Solenoid Hold” begins, ETS relay is energized while fuel relay is de-energized;
- “Fail to Stop Delay” begins, complete stop is detected automatically;
- Genset is placed into standby mode after its “After Stop Time”.
MANUAL START/STOP
- Press to start genset. It will detect complete start and accelerate to high-speed running automatically. With high temperature, low oil pressure, over speed and volt abnormal during genset running, controller can protect it to stop quickly (Please refer to Start Sequence b-g).
- Press
to stop the running genset (Please refer to Stop Sequence b-f).
NOTE
- The genset can be stopped manually in remote start status; at this time, remote input is inhibited and it will be active when remote input is closed again.
- After start conditions are satisfied, accumulative running timer will be initiated; at the same time, the last blinking decimal of nixie tube indicates that genset works normally.
PROTECTION
- Low Oil Pressure: detect after Safety On, Alarm Stop when Low Oil Pressure input is active and lasts for 2s.
- High Temperature: detect when start, Alarm Stop when High Temperature is active and lasts for 2s.
- Over Speed: detect when start, Alarm Stop after duration exceeds Over Speed Stop Delay.
- Gen Over Volt: Alarm Stop when the controller detects genset voltage exceeds overvoltage value and delay exceeds abnormal delay.
- Gen Under Volt: Alarm Stop when the controller detects genset voltage less than under voltage value and delay less than abnormal delay.
- Emergency Stop: ETS output immediately when Emergency Stop is active, in the meanwhile fuel, preheat and start signal are cut off and Emergency Shutdown Alarm Signal is sent.
- Fail to Start: Alarm Stop when start failed in preset start times.
- Gen Under Frequency: When genset is normal running, controller detects gen frequency falls below under frequency value and the “under frequency” delay has expired, under frequency shutdown alarm will be sent.
- Gen Over Frequency: Detection when start genset, if gen frequency exceeds over frequency value and the “over frequency” delay has expired, over frequency shutdown alarm will be sent.

PARAMETERS SETTING
PARAMETERS REGULATION
When the controller is running, press 
for 3s, it will enter into parameter number menu and LED will display 
- Press and to downturn/upturn parameter number;

CASE DIMENSIONS
Controller is panel built-in design; it is fixed by clips when installed
Battery Voltage Input
NOTE
MGC100 controller can suit for widely range of battery voltage DC( 9~18 )V. Negative of battery must be connected with the engine shell soun dly. The diameter of wire which from power supply to battery must be over 1.0 mm 2. If floating charge configured, please firstly connect output wires of charger to battery’s positive and negative directly,
then, connect wires from battery’s positive and neg ative to controller’s corresponding input ports in order to prevent
charge disturbing the controller’s normal working.
WARN: In running process, removing start battery is strictly prohibited
Speed Sensor Input
NOTE: Speed sensor is magnetic equipment which is installed on engine body for testing flywheel teeth number. 2
core shielding wire is used for the connection of the sensor and controller. The wire is supposed to be connected to 11 terminal of controller with one end and the other end hanging in the air. The other two signal lines connect separately to 11 , 12 terminal. Speed sensor output voltage is supposed to be at AC (1 1-24)V (virtual value) when it is in full speed range, and AC12V (when in rated rotate speed) is recommended. When install the s peed sensor, screw it to contact the flywheel firstly, inverse it with 1/3 circle, and then tighten the nut finally.
Withstand Voltage Test
CAUTION
CAUTION: When controller has been installed in control panel, if the high voltage test is need needed, please disconnec con troller’s all terminals in order to prevent high voltage into controller and damage it.
TYPICAL APPLICATION
NOTE: When it controls petrol genset, terminal 4 connects with ignition control; when it controls diesel genset, terminal 5 needs to short connect with B+, terminal 4 needs to connect with fuel output
