Parameter
Left value/Function
Right value/Function
15
maximum exhaust gas
temperature A
time delay (e.g. 0 sec)
maximum limit (e.g. 700 °C)
if the limit set at this temperature sensor is
exceeded by the set time delay, the machine
will trip
16
minimum exhaust gas
temperature A
waiting time (e.g. 120 sec)
minimum limit (e.g. 75 °C)
the temperature sensor must have exceeded
this limit after the start of the machine and
after the set waiting time, otherwise the ma-
chine will trip
(sensor function monitoring)
17
exhaust gas temperature
release
waiting time (e.g. 5 sec)
release temperature limit (e.g. 300 °C)
if the maximum exhaust gas temperature limit
has been exceeded, the temperature value
must drop below 300 °C for at least 5 sec,
before the fault can be acknowledged
18
battery
undervoltage
time delay (e.g. 20 sec)
minimum limit
if the battery/24
V
control voltage drops
below this limit, the machine will trip after the
time delay
19
starter limit
firing speed
limit, at which the starter will be
switched off (e.g. 450 rpm)
limit, at which the control recognizes the
started engine and does not repeat the start
(e.g. 650 rpm)
20
set speed
overspeed
set value for the speed
maximum limit of the overspeed
if the set limit is exceeded, the machine will
trip
21
fan
start-up time/after-run
time
start-up time until module start
after-run time (e.g. 30 min)
act
ive from the „warm-up limit“ (60 °C) and
module start
10 sec after-run at <60 °C
22
cooling water pump
start-up time/after-run
time
start-up time until module start
after-run time (e.g. 30 min)
active from the „warm-up limit“ (60 °C) and
module start
10 sec after-run at <60 °C
23
temperature controller
minimum
control valve minimum opening
angle (e.g. 10 % = 1
V
)
active from start-up time until the
end of the pump’s after-run time
reserve
24
temperature controller
KP/TN
KP value (e.g. 5.0)
amplification factor of the regula-
tors
TN value (e.g. 2.0)
re-setting time of the regulator
25
governor
1 = 10

V
-----------------------------------------
type 1 10
– 0 V (GAC)
starts regulating at 8 V = 1 500 rpm
10 V = approx. 1 450 rpm
0 V = approx. 1 800 rpm
type 2 0
– 5 V (Heinzmann)
starts regulating at 1 V = 1 500 rpm
0 V = approx. 1 450 rpm
5 V = approx. 1 800 rpm
26
after-run time of the en-
gine
after-run time of the engine under
no load after the alternator con-
tactor has been switched off
27
alternator overcurrent
time delay (e.g. 1 sec)
maximum limit
if the set limit set is exceeded by the set time
delay, the machine will trip
