The operator:
Self-Locking worm-wheel operator with integrated brake system. Two shafts with free ends. The limit switch shaft with its own drive worm is integrated in the gear box and runs in oil.
The worm-wheel of special bronze and worm are equipped with ball bearings for noiseless operation. It has standard a range of 33 rotations of the main shaft.
The AC motor is directly with standard voltage 3-phase AC 230/400 V. (special voltage at options). All protruding shaft ends are sealed against oil leakage, so the unit can be mounted in any position: the horizontal position is recommended.
The control box:
The control box is mounted on the drive section and is built according to VDE guidelines.
Control voltage 24 V. Auxiliary push buttons open – close for operation during mounting. Possibility of connection of remote controls of any kind, safety rail control, photocells etc. Auxiliary push buttons open – close for operation during mounting. The operator can also be equipped with a limit switch system ES10. The limit circuit then consists of a potential-free limit switch, a control current limit switch for determining the end positions and a safety switch for each direction of rotation.
The standard version also includes an emergency crank with electric emergency crank protection.
The Emergency chain operation
This can be either lateral to the drive (KNG) or positioned at the front of the motor (RKG).
Both for horizontal or vertical mounting. It is operated by means of a reel chain. Switching on and off of the braking system is by means of a separate chain. The integrated security switch avoids that the engine starts during the emergency operation. During the use of the emergency unit the end positions continue preserve.
Maintenance:
The drives are maintenance-free. Lifetime lubrication makes every oil change unnecessary. Adjusting the brake is basically not necessary.
Gear box with irreversible worm and worm-wheel. Two shafts with free ends, the wormwheel of special bronze and worm are equipped with ball bearings for noiseless operation. The worm-wheel of special bronze and worm are equipped with ball bearings for noiseless operation. The standard version has 30 revolutions at the drive shaft. The AC motor is directly with standard voltage 3-phase AC 230/400 V. (special voltage at options). All protruding shaft ends are sealed against oil leakage, so the unit can be mounted in any position: the horizontal position is recommended.
On the reduction is a box mounted with limit switch ES10, this can be connected with a separate controller which can be chosen out of the LST/WST range. The limit switch consist out of a potential free switch, a control current limit switch for the end positions and a safety switch for each side of rotation.
The RKG is mounted in front of the engine for a horizontal or vertical placement. Only one chain for manual operation. The integrated security switch avoids that the engine starts during the emergency operation. During the use of the emergency unit the end positions continue preserve.
The safety bearings FV 20/35 E to FV 360 E have been tested and approved by the TÜV SÜD Industry Service and got because of those tests also corresponding certificate numbers. They correspond to the European Standards DIN EN 12604 / DIN EN 12605 (edition Aug. 2000 ) and GS – BE – 04 (edition Jan.2001). TÜV-certificates are on request available. All types are equipped with a damping system, witch absorbs the blocking moments considerably. The standard safety bearings have also an electric circuit breaker and in option there is a water protected version. The safety bearing can not be placed on the same side as the traction or motor!
This fire protection rolling gate drive is a complete unit that closes the rolling gate automatically without any current by fire. It exist out off a spur gear transmission with an electric motor of 230/400 V. AC 50 Hz. Inside is a centrifugal brake mounted, a service brake of 205 V. and a safety brake of 24 V. On the drive is a control unit mounted with 3 phase safety circuit, contacts, motor protection, control current fuse and push buttons fort he adjustment off the limit switches.
Operation of drive
The drive and fire protection rolling gate will standard be closed and opened by means of push buttons or a key switches. When smoke appears or temperature increase a detector shall cut the current off the 24 V circuit and loosen de magnetic clamp which set the brake free. The fire protection rolling gate shall shut automatically due to his own weight, the centrifugal brake controls the speed of the gate. By means of a safety contact rail, which is connected with the 24 V brake, the rolling gate will stop as long as the safety contact rail is activated. When the fire protection rolling gate is almost closed a rod shall move the lifting lever of the brake and let the gate stop at the right end position. At option a mechanical siren can be delivered, this siren produces 100dB. At the end of the fire alarm the lifting lever of the brake must be pushed back to the magnetic clamp. This operation can (at option) be simplified mechanically or automatically.
NGS-RS is a compact assembly entity with limited dimensions. The worm-wheel gear-box is equipped with an infinitely variable torque limiter and an unlock system. The safety torque limiter is built between motor and gear-box. This means that when the motor is stopped the irreversible system of the gearbox locks the gate so that normally no additional locks are required.
Due to the unlock system it is possible to open the gate manually. The motor can be mounted horizontal or vertical. Standard voltage 3-phase 230/400 V. motor with thermal protection in the coil (special voltage at options).
The limit switch
On the reduction is a box mounted with limit switch ES10, this can be connected with a separate controller which can be chosen out of the LST/WST range. The limit circuit then consists of a potential-free limit switch, a control current limit switch for determining the end positions and a safety switch for each direction of rotation.
Noiseless, self-locking worm-wheel operator with additional brake and integrated infinitely variable torque limiter between motor and gearbox. This means that when the motor is stopped the irreversible system of the gearbox locks the gate so that normally no additional locks are required. Only one free shaft, right or left. The wormwheel of special bronze and worm are equipped with ball bearings and runs in oil. The limit switch shaft
with its own drive worm is integrated in the gear box and runs in oil. It has standard a range of 33 rotations of the main shaft. The AC motor is directly with standard voltage 3-phase AC 230/400 V. (special voltage at options). In case of emergency it is possible to open the gate manually by unlocking the torque limiter This does not affect the limit switch setting. Horizontal position is recommended.
The control box
Standard equipment of the operators: electric controller according the VDE prescriptions. Control voltage 24 V. Auxiliary push buttons open – close for operation during mounting. Possibility of connection of remote controls of any kind, safety rail control, photocells etc. It consist out of 1 micro-switch each for the open and close position and a safety limit switch for each side of rotation. The operator can also be equipped with a limit switch system ES10. The limit switch consist out of a potential free switch, a control current limit switch for the end positions and a safety switch for each side of rotation.
Operator for swinging gates protected against the most conditions. Due to the robust method of construction it is extremely reliable and especially suitable for industrial use. A noiseless self-locking worm-wheel gearbox with integrated infinitely variable torque limiter. The worm-wheel of special bronze and worm are equipped with ball bearings and runs in oil.
The self-locking of the operator and the stretched position of the swing arm mean that the gate is mechanically locked in the closed position. An additional gate lock is not necessary. The quick release enables manual emergency operation. Furthermore, this operator is equipped with a three-phase motor and magnetic limit switches.
By using a quick unlocking system the gates can be opened manually whereby the motor limit switch setting remains unchanged.
The separate control boxes can be chosen from the WST/AST series.
