Right value/Function
set value for the output for gas type A
(e.g. 125 kW)
activated by digital input 28
of its output until this cooling water tempera-
ture is reached (e.g. 60 °C)
output limit
if this limit (e.g. 130 kW) is exceeded by the
set time delay (10 sec), the machine will trip
reverse power limit (e.g.20 kW)
if this limit is exceeded by the set time delay,
the machine will trip
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)
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
regulator dead band (e.g. 1 kW)
no re-adjustment, if the actual output value
levels within +/- 1 kW of the set value for the
output
output reduction (e.g. 20 %) in the case of
„knocking"; activated by digital input 21
set value for the Lambda regulator for gas
type A (e.g. 20 mV)
-----------------------------------------------------
-----------------------------------------------------
regulator dead band (e.g. 3 mV)
no re-adjustment, if the actual Lambda probe
value levels within +/- 3 mV as compared with
the set value
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
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
