AMMA 16/10.S

The Multifunctional Actuator is a multi-output module, integrating multiple output functions, including switch output, curtain DC/AC output, fan output and valve output. You can configure the functions of the module according to your requirement, such as a part of the output for controlling the switch, a part of the output for controlling the curtain, and a part of the output for controlling the fan. With 4, 8, 16 and 24 outputs for selection, the output of different output channels is different. One relay in the device represents one output, and some functions may require multiple outputs. And with manual operation buttons on the top of the product, it is more convenient to cope with engineering debugging. The Multifunctional Actuator is a modular mounting device. For easy installation in the distribution box, it can be mounted on a 35 mm D-rail according to EN 60 715. The device is screwed to the electrical connection and the bus connection is directly connected via KNX Terminal connections, system power supply does not require an additional supply voltage other than the bus.

Function:

Switch output

which can connect some electrical loads, such as lighting, sockets and heating control. One output occupies one relay control, and each output has electronic switch control. The module offers the following functions: 

• Switch 
• Time function: on/off delay 
• Time function: flashing switch, for lamps of aging test 
• Time function: staircase lighting
• 8 scenes, recall and storing via a 1byte object 
• Logic operation: AND, OR, XOR, GATE function, up to three logic inputs 
• Status response, for know the current output state in the visualization 
• Forced operation, two data types: 1bit/2bit, for force action on or off, with the highest priority 
• Heating valve control 
• Set the relay contact position after bus voltage recovery 
• Set the relay contact position after bus voltage failure 
• Manual switch outputs

Shutter AC/DC output

can connect with motor blinds, awnings, roller blinds, vertical blind, etc. There are maximum 12 outputs with 230V AC 370W (4/8-Fold) or 1000W(16/24-Fold) motor or dry contact controlling motor or 6-channel DC control mode (DC motor control type). The output contacts for the directions UP and DOWN. The pause on change in direction can be set via the parameters. The curtains AC and DC are wired differently. The curtain AC occupies two relays per channel, and the curtain DC occupies four relays per channel. For the specific wiring method, please refer to the connection diagram on the manual, but their functions are similar.

The specific functions are summarized as follows: 

• Movement UP/DOWN
• Stop/Louvre adjustment 
• Move to position 0……100% 
• Adjustment Louvre to position 0……100%(only “Venetian Blind” working mode) 
• Set 8 scenes, store or recall via a 1byte object 
• Automatic sun protection 
• Safety function 
• Status response, query and reply the current shutter/blind position and operation mode to the bus, thereby indicating the status in the visualization device 
• Two working mode :Venetian Blind and Shutter

Fan Drive Control

can be connected to a single-phase fan, supports up to 3 levels of fan speed adjustment, the output contacts are the same as the switch output. The function is summarized as follows: 

• Support the fan with 1-2-3 level fan speed 
• The fan has two operating modes: step switch and steering switch 
• Forced operation: The fan speed is only allowed within the allowed fan speed range, with the highest priority 
• Automatic operation: Automatically run the fan speed according to the control value. The control value is obtained by the sensing device on the bus, and the minimum running time of the fan speed can be set. 
• Normal operation: manually control the operation of the fan, such as through the operation panel, etc. 
• Fan with multi-level fan speed can set start-up characteristics 
• Single-level fan speed fan can set on/off delay or minimum running time 
• Status feedback, such as automatic operation status, fan switching status, fan speed, etc. 
• Operational control of bus power-up or power-down behavior

Valve control

can be used to connect 2 control or 4 control coil system, cooling valve and heating valve respectively use separate relay output, there are three types of control:

• continuous (3 point, open and close),
• PWM switch (continuous, PWM) 
• 2-point switch type (2 state-ON/OFF).

The continuous type controls the opening of the valve according to the control value of the valve. It can completely open or close the valve, and can also stop the valve in an intermediate position. This type of control is suitable for driving three-wire valves.

The PWM switch type can only make the valve fully open or completely closed. The valve is cyclically operated according to the control value (1byte) and PWM cycle. The valve switch is divided into normally open or normally closed. This control type is suitable for driving two-wire system. Valve.

The 2-point switch type is similar to the PWM switch type, and can only be fully opened or completely closed. The difference is that it is directly turned on or off according to the control value (1 bit) on the bus. It is usually suitable for the case where the switch valve is controlled according to the temperature difference. And suitable for driving two-wire valves.

The function is summarized as follows: 

• Supports three valve control types 
• Monitor the control values on the bus to send fault status 
• Valve characteristic curve correction (only for continuous valves) 
• Automatic valve adjustment (for continuous valves only) 
• Prohibit/enable heating or refrigerating valves 
• Valve position status feedback or query 
• Manual or automatic cleaning of the valve, sending the cleaning status

Programmers are able to use the Engineering Tool Software ETS (ETS4 version or above) with a .knxprod file to allocate the physical address and set the parameters. To make sure that all the programmable functions are used correctly, you must check the connection of the loads before use and note technical characteristic of loading equipment, particularly shutter driver, they refer more technical characteristics, some characteristics are inherent, if not properly set them, it is likely to cause the load device damage or not operating correctly.
