Installation and operating instructions

• Valve blocking protection

The blocking protection prevents a locking of the cone during longer valve 
shut down. Variable definitions of cycle as well as route are available with the 
help of the controller.

• Micro USB interface

The micro USB interface can be used for providing the SmartDrive MX with 
energy.

• Keyboard lock

It is possible for the SmartDrive MX to receive a command for key locking via 
the controller. In that case, you will no longer be able to set the target 
temperature for the  SmartDrive MX manually. If key lock is enabled during the 
emptying of the batteries, it will be disabled for the new adapting process. If 
the SmartDrive MX will loose the connection to the controller, the input lock 
will be disabled to allow a manual temperature control.

• Transmitting cycle

The SmartDrive MX spends the greater part of its operating time in deep sleep 
mode so as to keep energy consumption as low as possible. You can select 
the periods for deep sleep mode by using a radio telegram from a selection of 
63 time cycles. The predefined times for the deep sleep mode range from 10s 
to 42h. If the index of this field variable is set to 50 or above, the actuator will 
interpret this as a command for changing to so-called summer mode.

• Summer mode

Summer mode is characterized by deep sleep mode that from now on will last 
at least 3h. The moment this mode is enabled, the valve will open completely, 
thus conserving the valve seal among other things. You can exit summer 
mode by reducing the cycle period for the deep sleep mode to an index that is 
smaller than 50. Afterwards, you must re-adapt the actuator to the valve so as 
to re-establish reliable operation.

• Error messages

Various errors may occur during normal operation or commissioning. Error 
messages are displayed on the display screen and communicated to the 
controller by radio. 
For possible error messages, see checklist.
