All operator systems are equipped with mechanical emergency operation of the electric motor as standard. This enables the sectional door to be opened even in the event of a power failure. The function must be switched on and off manually using the operating cables. The gearbox can then be operated using the chain.

A drive with an unlocking device is also possible. In this case, the gearbox is separated from the spring shaft using the operator with quick-release cables. The sectional door can thus be opened more quickly by hand in the event of a malfunction. Naturally, a sectional door with quick release is equipped with a spring breakage safety device.

If the door is no larger than 12^m2 and you only use it occasionally, you can choose to operate it using a pull rope (gear ratio 1:1).
. This requires a certain amount of physical effort. It is not possible to fix the opening position.

The sectional door can thus be opened more quickly by hand in the event of a malfunction. Naturally, a sectional door with quick release is equipped with a spring breakage safety device.

Operation by reel chain (transmission ratio 1:4) requires less effort than operation by pull rope. The system - suitable for sectional doors up to 30^m2 - offers the advantage that the door can be fixed in the desired position.

This system is particularly suitable for gates that are rarely used. The door is opened by pressing a button once. When closing, however, the operating button must be pressed until the door is closed. In this way, the person operating the door can keep an eye on whether dangerous situations arise.

Are the doors moved frequently? Then pulse control is recommended. It automatically moves the door to the electronically adjustable end position without having to hold the switch. The closing edge of the door contains a closing edge safety device or an accident prevention contact strip for obstacle detection.

Suitable for frequently used doors thanks to its high running speed and low energy consumption. The system is available in two versions: with direct inverter (0.2 - 0.4 m/s) or with frequency inverter (max. 0.6 m/s). This is ideal for high doors that are operated frequently (e.g. fire brigade doors); both variants close at normal speed.

The T75 control unit is a basic control unit for industrial sectional doors. The T75 has a 3-button control unit and connections for closing edges, light curtains, slack rope switches and wicket door switches (not for low thresholds). The T75 can also be fitted with an optional 433 MHz radio module. This is a dead man's control unit that can also be extended to a limited extent as a pulse control unit.

The T100 control unit is a convenient premium control unit. The T100 has a display integrated in the cover, a 3-button control, a button for half openings and all the necessary connections for closing edges, light grids, slack rope switches and wicket door switches. In addition, functions such as automatic closing or door locking can be programmed. It is suitable for a motor power of 3 KW. There are also connection options for further additional controls

When the door system is being serviced, the power can be switched off using the main switch. By additionally securing this switch with a padlock provided by the customer, it is possible to prevent third parties from accidentally switching the power back on during maintenance.

The miniature lock disables the control unit keypad to prevent unauthorised operation of the door. Only authorised persons have a key with which the door can be operated after it has been switched on.

In the event that local, country-specific or international laws stipulate that an electrically operated opening or closing of a sectional door must be able to be stopped by means of an emergency stop, Novoferm offers the option of installing an emergency stop switch on the control section.

The door can be operated from there using a separate key switch that can be mounted on the outside wall. There are two versions, a flush-mounted version and a surface-mounted version.

To make it possible to open the door at any time and around the clock, the door can be operated with a code button. This is a particularly practical solution where day and night access is required to secure collection or delivery points for transport and courier companies.

If a door needs to be operated from several areas or a remote control is required, e.g. from a porter's lodge, the solution lies in an additional control unit. All buttons located on the control unit control box are also available on this practical open/stop/close If a door needs to be operated from several areas or a remote control is required, e.g. from a porter's lodge, the solution lies in an additional control unit. All the buttons on the standard control panel are also available on this practical open/stop/close control panel.

Using the pull switch, the door can be operated from the forklift truck without the driver having to dismount. This solution is ideal if many employees use the door and you do not want to distribute so many hand transmitters. The pull switch is often attached to a boom a few metres in front of or behind the door.

The door system can easily be upgraded to a system with remote control. You have the choice between 2- or 4-channel hand-held transmitters, with which two or four different doors can be operated. With this option, the door must also be fitted with a stationary safety light barrier.

As an option, particularly robust 3, 16, 15 or 99-channel hand-held transmitters with an external 230 V receiver, to which 3 doors can be connected simultaneously, are also available for industrial sectional doors.
