Installation and Usage instructions
Mechanical installation
Insert into the standard DIN rail and ensure the lock is in place.
It is recommended to reserve 10 mm of heat dissipation space on both sides.
Electrical wiring
A1/A2 is connected to the power supply (24-240 V AC/DC, polarity independent);
Output terminals: 13/14 (normally open), 11/12 (public), 11/14 (normally closed);
The control signal is connected to A1 or a dedicated trigger terminal (depending on the functional mode).
Function Settings
Use the dip switch to select the desired time function (refer to the panel illustration);
