Right value/Function
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
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)
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
minimum limit
if the battery/24 V control voltage drops
below this limit, the machine will trip after the
time delay
limit, at which the control recognizes the
started engine and does not repeat the start
(e.g. 650 rpm)

if the set limit is exceeded, the machine will
trip

0 V = approx. 1 800 rpm
type 2 0 – 5 V (Heinzmann)

0 V = approx. 1 450 rpm
5 V = approx. 1 800 rpm
