Construction

The special design and use of components installed on the surface make it possible to reduce the overall dimensions. The case, made of plastic, protects the control panel from possible damage as a result of collisions, careless opening, dust ingress and contact with the external environment. The varistor protects the control system from voltage surges in the electrical network. The built-in fuse protects the internal relays of the control unit in case of a short circuit at the outputs (valves, ignition transformer, engine and lock signal).

Connection

To connect external components, the control unit can be equipped with an N-type connector equipped with a screw terminal block, which provides a simple and safe connection. It is recommended to use M4 type screws to attach the sockets. To attach the control element to the outlet, use the pin included in the control unit package.
