Actuator IC 40

The actuators IC 20 and IC 40 are for all applications that require precise, controlled rotary movement between 0° and 90°. They can be mounted directly onto the butterfly valve BVG or butterfly valve BVH to control gas and air flow rates on gas burners. They are designed for control ratios up to 1:10.

An optional integrated feedback potentiometer offers the option of monitoring the current position of the actuator. This scan function can be used in automation processes.

The IC 40 offers additional functions. It can be used in continuously controlled burners and in step-by-step-controlled burners.

Settings on the actuator IC 40 can be made using a PC with the software BCSoft. All the relevant settings for the process are made using the software via an optical interface. Various operating modes, which may be modified, are stored in the unit. In addition the control type (two-point signal, three-point step signal, or continuous control), running times, adjustment angles, and intermediate positions can be programmed.

The actuator can also be controlled manually using the software.

Once set, all the parameters can be saved on the PC and copied from there into other actuators, saving time during the commissioning process.

Service technicians can call up statistical data using BCSoft, such as hours of operation, actuating cycles, and an error history. Some values can also be set to zero, for example, to record data over a specific period of time.

	Applications Click on images for close-up view. 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. 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. 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. 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. 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.
