No
.
Parameter
Left value/Function
Right value/Function
1
set value for the output
set value for the output for gas
type B
(e.g. 120 kW)
set value for the output for gas type A
(e.g. 125 kW)
activated by digital input 28
2
warm-up limit
------------------------------------------ warm-up limit, the machine will run with 50 %
of its output until this cooling water tempera-
ture is reached (e.g. 60 °C)
3
output limit
output limit
time delay (e.g. 10 sec)
output limit
if this limit (e.g. 130 kW) is exceeded by the
set time delay (10 sec), the machine will trip
4
reverse power
reverse power
time delay
(e.g. 20 sec)
reverse power limit (e.g.20 kW)
if this limit is exceeded by the set time delay,
the machine will trip
5
power ramp
higher/lower
increase/decrease in set value
of the output
period (e.g. 1 sec) per kW
increase/decrease in set value of the output
(e.g. 2 kW) per sec
the machine will reach its set value in 50 sec
with a set value of 100 kW and a setting of 2
kW per sec (approximate values depending
on the governor setting)
6
output regulator monitor-
ing
monitoring period
(e.g. 15 min)
limit (e.g.5 kW)
if the set value for the output deviates either
way by more than 5 kW for more than 15 min,
the machine will trip
7
output regulator
dead band
-----------------------------------------
regulator dead band (e.g. 1 kW)
no re-adjustment, if the actual output value
levels /- 1 kW of the set value for the
output
8
knocking
output minimum
-----------------------------------------
output reduction (e.g. 20 %) in the case of
„knocking“; activated by digital input 21
9
set value for the Lambda
regulator
set value of the Lambda regula-
tor for gas type B
(e.g. 700 mV)
set value for the Lambda regulator for gas
type A (e.g. 20 mV)
10
pulse time of the Lambda
regulator
Lambda regulator pulse time
(e.g. 0.2 sec)
-----------------------------------------------------
11
dead time of the Lambda
regulator
Lambda regulator dead time
(e.g. 2.0 sec)
-----------------------------------------------------
12
Lambda regulator
dead band
-----------------------------------------
regulator dead band (e.g. 3 mV)
no re-adjustment, if the actual Lambda probe
value levels /- 3 mV as compared with
the set value
13
Lambda regulator moni-
toring
monitoring period
(e.g. 15 min)
limit (e.g. 30 mV)
if the set Lambda value deviates either way
by more than 30 mV for more than 15 min, the
machine will trip
14
maximum cooling water
time delay
maximum limit (e.g. 92 °C)
if the limit set at this temperature sensor is
exceeded by the set time delay, the machine
will trip
