measurement of controller will increase(reduce) according the
increased(decreased) value of adjustment. The scope of
adjustment is ±10％.
But the calibration of coolant temp., oil pressure and fuel level
are different. Special explain, for coolant temp., oil pressure,
fuel level sensors maybe positive modulus (It means the sensor
output add along with input add), It maybe negative modulus(It
means the sensor output minish along with input add). Add or
minish adjust value lead to adjust result which is decided by the
real situation.

Alarm Stop：User-defined alarm, cause to shutdown when genset is running，
instruct to auxiliary input 1－4 stop
Attention：Display, alarm and protection of coolant temp., oil pressure and fuel
level can be realized by measuring the analog volume，and also can be realized by
defining the high coolant temp., low oil pressure, fuel level to the auxiliary input
portion. If the analog volume and alarm input are exist together in the system, then
any of alarm can come into being protection and alarm. If the switch alarm
protection is no need, please define the auxiliary input to another function; if the
analog volume alarm protection is no need, please set the alarm up-low limit to the
measurement limit so as to not alarm.
Fuel temp. & oil pressure sensor just for display, not for control
Output of acceleration and deceleration are in coordination with limit of
acceleration and deceleration to realize mechanical speed adjustment. Normal
speed adjustment function can be realized by definite output of acceleration and
deceleration but not detect properly and not alarm.
Since output and input can be user-defined, Minco 830/840 controller’s input and
output function actualized is much more than the real amount of input and output.
Although some function of controller has been appointed, which can’t execute if
there is no definition for input and output port.
5.3．Delay Time Instruction
Delay of
“cool stop
(down)”
When the controller is in “Auto” state, once the “Remote start”
switch input turn off and mains resumed the genset will be
stopped after delay.
Delay of
“genset

time”
When the genset start and begin to delay, if the start succeed
condition is satisfied (genset rotate speed>trip speed) it’s
consider to be genset start successful and stop delaying.
Delay of
“bypass
time”
After the gen-set start successfully, that begin to start the
delay of bypass. "low oil pressure", "high coolant temperature "
etc will not be monitored during the delay to avoid mistake
alarm when genset in initially starting.
Delay of
“energize
to stop”
Output of auxiliary stop relay is energized when engine
stop.”Ergize to stop” delay begin, output of auxiliary stop relay is
de-energized when delay finish.

- 13 -
Delay of
“pre-fuel”
Delay of pre-fuel has begun before engine starts and relay of
pre-fuel close at the same time., Relay of pre-fuel cutoff after
delay finish, and engine start to crank.
Delay of
“idle start” Delay of idle start begin after the engine starts successfully, and
the relay of “idle start” begin to work at same time.
Delay of
“idle stop” When genset stops, delay of “idle stop” begin after deceleration
finish, and idle relay begins to work.
Delay of
“ACC”
Genset start successful and idle (start) finish. Acc relay closed
when Acc delay begins.”Acc failure” will alarm when the delay
finish but not get the signal of Acc in a right position.
Delay of
“Auxiliary
Input 1”
Delay begins at the time of auxiliary input 1 closes, delay will
break off when the state returns to be normal. When the input
still closes after delay finishes, it will alarm.
Delay of
“Auxiliary
Input 2”
Delay begins at the time of auxiliary input 2 closes, delay will
break off when the state returns to be normal. When the input
still closes after delay finishes. it will alarm.
Delay of
“Auxiliary

Delay begins at the time of auxiliary input 4 closes, delay will
break off when the state returns to be normal. When the input
still closes after delay finishes, it will alarm.
Delay of
“Loss
Speed”
Delay begins when no speed signal is detected during the
running. If the speed signal isn’t be detected until delay finish,
then it will alarm.
Delay of
“Supply(clo
se) time”
The time of the closing relay output is set to 0, the relay
continuous has output.
Delay of
“Retransfor
mation”
When “remote start” switch turn off and starts to delay, the
controller is in a “auto” state, and it gets ready to stop after
delay finishes.
Delay of
“over load”
Delay begins when current is exceed the alarm upper limit. If
the current is in normal, delay will break off. When it’s still over
current after delaying, it will be overload to stop. When the
current exceeds stop upper limit, then protect to stop without
any delay.
Delay of
“over
voltage”
Delay begins when voltage exceeds the upper limit. When
voltage returns to normal during the period of delay, delay will
be interrupted. If the phenomena of overvoltage still exists after
delay finishes，then it will be in an overvoltage protection to stop

- 14 -
Delay of
“over
frequency”
Delay begins when the frequency exceed the upper limit. When
voltage returns to normal during the period of delay, delay will
be interrupted. If the phenomena of over frequency still exists
after delay finishes, then it will be in an over frequency
protection to stop. If the frequency is above the upper limit, then
it will stop to be protected without any delay.
Delay of
“Warm Up”
It provides a delay between starts and loads successfully. It can
prolong the time of transferring to supply. It also can help the
genset to run to supply in the best condition and avoid friction
loss of genset to the minimum when it’s in not an emergency
situation.
Delay of
“Decelerati
on”
Delay begins at when genset stops, and deceleration relay will
close. The controller will alarm for “deceleration failure” when
the right deceleration signal can not be detected after delay
finishes.
5.4．Timing Start Instruction
Timing start is only valid on the automatic state of Minco830/840.
Auto start estimate the now date( month-day/week) to be correct or not, if it’s
correct, then start the machine to work or stop the machine to halt at the setting
time(hour: minute).All the parameters are set to 0, then it means time start function
is not available.
Any one of month/day/week is set to 0，it means that the setting corresponds with
current time. When month/day/week are all set to 0, it means timing start daily.
When day and month are set to 0，it means timing start weekly. When month and
week are set to 0，it means timing start monthly.
For example:
The date of timing start is set to:08-00/01 Time: 10:00-12:20. It means that the
genset will starts at 10:00,and stops at 12:20 in every Monday of every week in
August.
The date of timing start is set to:00-03/00 Time: 10:00-12:20. It means that the
genseet will starts at 10:00,and stops at 12:20 in the 3rd of every month.
Three times interval can be set on every day, please set “0” to no-use time
interval.
