indicator are normal.

In setting menu, upturn or decrease parameter value (it can be

double-clicked).

In setting menu, press it for more than 3s to exit this menu.

Page/Confirm

Switch display contents of nixie tube in normal status.

Pressing it for more than 3 seconds entry the parameter configuration

menu.

In setting menu, press this button to modify and save value.

4.2.3 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.

4.3 OPERATION

4.3.1 REMOTE START SEQUENCE

a) When remote start signal is active, “Start Delay” timer is initiated;

b) When start delay is over, preheat relay energizes (if configured), “Preheat delay” is initiated;

c) 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);

d) Should this start sequence continue beyond the set number of attempts, the fail to start

indicator will be illuminated;

e) 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);

f) During “Start Idle” delay, under pressure alarm is inhibited. When this delay is over, “Warming

Up” delay is initiated (if configured);

g) After the “Warming Up” delay, genset will enter into Normal Running status.

4.3.2 REMOTE STOP SEQUENCE

a) After remote start, when remote start signal is invalid, “Stop Delay” timer is initiated;

b) Once this “stop delay” has expired, the “Cooling Delay” is then initiated;

c) During “Stop Idle” Delay (if configured), idle relay is energized;

d) “ETS Solenoid Hold” begins, ETS relay is energized while fuel relay is de-energized;

e) “Fail to Stop Delay”begins, complete stop is detected automatically;

f) Genset is placed into standby mode after its “After Stop Time”.

MGC100 Petrol Genset Controller User Manual Page 9 of 16

4.3.3 MANUAL START/STOP

a) 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).

b) Press to stop the running genset (Please refer to Stop Sequence b-f).

NOTE:

a) 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.

b) 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.

5PROTECTION

1) Low Oil Pressure: detect after Safety On, Alarm Stop when Low Oil Pressure input is active and

lasts for 2s.

2) High Temperature: detect when start, Alarm Stop when High Temperature is active and lasts

for 2s.

3) Over Speed: detect when start, Alarm Stop after duration exceeds Over Speed Stop Delay.

4) Gen Over Volt: Alarm Stop when the controller detects genset voltage exceeds overvoltage

value and delay exceeds abnormal delay.

5) Gen Under Volt: Alarm Stop when the controller detects genset voltage less than under voltage

value and delay less than abnormal delay.

6) 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.

7) Fail to Start: Alarm Stop when start failed in preset start times.

8) 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.

9) 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.
