The SAS 61.03 / MO electromotive actuator with Modbus remote communication is suitable for 2- and 3-way lift valves V..G44 .., VVG55 .. and VVG549 with a lift height of 5.5 mm in heating, air conditioning and ventilation systems. The valves can be used as control and as shut-off valves.

The drive is very easy to install, no special modifications are required. There is an LED movement and status indicator on his body. It can be optionally expanded with additional functions and an auxiliary switch. It can also be installed on older types of valves after fitting with the ASK 30 mounting kit. With it, it can also control valves X3i .., VVG45 .., VXG45 .., VXG46 .. and VVI51 ...

Properties:

Voltage 24 VAC / VDC
Positioning force 400 N
Positioning time 30 s
Modbus RTU
Stroke 5.5 mm
Manual setting

Function:

Self -calibration - must be performed during the first commissioning. The drive lowers to the lower end position and saves the measured values.
Valve seat detection - depends on actuator power. After calibration, the actuator stores the exact stroke of the valve.
Foreign body detection - the actuator is able to detect the presence of a foreign body in the valve and its clogging. If this occurs, the actuator will make three attempts to release the valve. If they do not help, the drive turns on the LED singalization and continues limited operation.
Modbus RTU - not galvanically isolated. Receives the required valve position (0 ... 100%), sends the current position (0 ... 100%). Controls the valve remotely Open / Close / Min / Max / Stop. Monitors the setpoint and backs up the settings.
