BIOCLASS iC 150

code ALARM

DESCRIPTION

E-62

Low oxygen concentration.

The lambda sensor has measured an oxygen

concentration that is too low over a long period. The
boiler will perform safety interlock.
Please contact your nearest official Technical

Assistance Service to have it replaced.

E-63

High oxygen concentration

The lambda sensor has measured an oxygen

concentration that is too high over a long period. The

boiler will perform safety interlock.
Please contact your nearest official Technical

Assistance Service to have it replaced.

E-64

Lambda sensor error

The lambda sensor has given a value outside of the

range in the calibration process. While adjusting the

combustion with the lambda sensor enabled the boiler
will perform safety interlock.
Please contact your nearest official Technical

Assistance Service to have it replaced.

E-65

Lambda sensor open circuit

The lambda sensor is broken or badly connected.

Please contact your nearest official Technical

Assistance Service to have it replaced.

E-66

sensors connected

simultaneously in the cascade system

Intermediate temperature probes in the buffer tank

have been connected. The MC cascade control

supports a maximum of 2 intermediate probes.

Disconnect the remaining probes.
If this alarm occurs repeatedly, please contact the
nearest official Technical Assistance Service.

E-86

Maximum power insufficient

The control has reduced the maximum power of the

boiler below a suitable level due to measuring an
insufficient air quantity in the burner input.

If this alarm occurs repeatedly, please contact the

nearest official Technical Assistance Service.

E-87

Sensor

Sbt2

connected to the cascade

system

Sbt2

has been connected to the boiler and will not

operate for the cascade system.
