076 Standard Fuels
if
1) Pre-filling / Ignition insert cannot
be performed because no fuel
2) Failure “FIRE OUT” occurs for the
second time within 2 hours.
3) during operation intermediate
hopper is not full despite power
reduction Check fuel level
Check burning parameters, adjust
as adapt
Clean intermediate hopper level

System must be started manually
077 Additional input
Additional input (e.g.: system
pressure, CO-sensor) active Check failure at additional input
aggregate
078 NIVEAU LEVEL
Active intermediate hopper level
sensor; low fuel level at intermediate
hopper Check fuel level

100 Floor temp. WARNING
at external monitoring:
*Digital input temperature ash floor
has responded
at monitoring via CAN:
*a sensor has exceeded the limit
value
▪
check the parameter
101 Floor Temperature fault
Error 101 (floor temp. warning) is
continuously active for 3 hours
during the burning process
▪
check the parameter
103 RECI mixing temperature
Sensor break; Value outside the
measuring range
(-10 - 120°C)
Check sensor, replace as renew
Check plug, replace as renew
Check wiring incl. connections,
replace as renew

104 Boiler spreading
Boiler spread too low at nominal
load (less than 8K)
▪
Reduce pump speed (step) to get
more spread
