Application

1 .1 Examples of application

1 .1 .1 Staged control

VAG + VAS 1
Two-
point
M
step
IC 40 + BVA
For processes that require a homogeneous tempera-
ture distribution in the furnace. The actuator IC 40 is
controlled by a two-point controller and operates in
On/Off or High/Low intermittent mode. The actuator
closes when the voltage supply is interrupted. The run-
ning time can be infinitely adjusted between 5 and 25
seconds.

M
IC 40 + BVA
For processes that require a homogeneous tempera-
ture distribution in the furnace and three burner capac-
ity levels. The actuator IC 40 is controlled by a program-
mable logic controller and works in High/Medium/Low
or High/Medium/Low/Off intermittent mode. This al-
lows the ignition stage to be started. The optional pres-
sure switch provides fail-safe monitoring of the maxi-
mum pilot air volume. The actuator running time can be
infinitely adjusted between 5 and 50 (75) seconds.
