Application for Actuator IC 40 IC 40, staged control

For processes that require a homogeneous temperature 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 running time can be adjusted between 5 and 25 seconds.
Application for Actuator IC 40 IC 40, staged control with three burner output levels

For processes that require a homogeneous temperature distribution in the furnace and three burner output levels. The actuator IC 40 is controlled by a programmable controller and works in High/Medium/Low or High/Medium/Low/Off intermittent operation. This allows the ignition stage to be started. The pressure switch provides failsafe monitoring of the maximum pilot air volume. The actuator running time can be adjusted between 5 and 50 (75) seconds.
Application for Actuator IC 40 IC 40, continuous control by three-point step signal.

The actuator IC 40 is controlled by the three-point step controller 3PS and moves the butterfly valve BVA to the ignition position. The burner starts.

Once the burner is operating, the operation signalling contact of the burner control unit BCU 460 closes. The BCU issues the Controller enable signal to the temperature controller. The butterfly valve opens or closes between the low-fire and high-fire rate positions depending on the capacity demand of the burner. When the three-point step signal is disconnected, the butterfly valve stops at its current position.

If both inputs on the IC 40 (DI 1 and DI 2) are actuated after the burner has been shut down, the butterfly valve closes further than the low-fire rate position.
Application for Actuator IC 40 IC 40, staged control with pre-purge

The central control system starts the pre-purge. Input DI 2 is actuated via the air valve output of the BCU and moves the butterfly valve BVA to the pre-purge position.

In the event of a temperature demand, the burner control unit BCU actuates input DI 1 via the valve output V1 and moves the butterfly valve to the ignition position. (Precondition: the IC 40 must have reached the ignition position on the instant of ignition.) The burner starts.

To activate the high-fire rate, DI 2 is actuated via the air valve output on terminal 26 of the BCU.

The butterfly valve moves cyclically between the high fire rate position and the low-fire rate position.
Application for Actuator IC 40 IC 40, continuous control with defined ignition position

The central control system starts the pre-purge. Input DI 2 is actuated via the air valve output of the BCU and moves the butterfly valve BVA to the pre-purge position.

In the event of a temperature demand, the burner control unit BCU actuates input DI 1 via the valve output V1 and moves the butterfly valve to the ignition position. (Precondition: the IC 40 must have reached the ignition position on the instant of ignition.) The burner starts.

The BCU actuates DI 2 via the air valve output. This enables the analogue input AI on the actuator IC 40. Depending on the capacity demand of the temperature controller, the butterfly valve BVA moves steplessly to the position between the low-fire rate and the high-fire rate as specified by the analogue input AI.

Specifications

Electrical
