2 Summary The drive motors of hoisting gear installations are controlled by cam controllers (master controllers) via contactors. Control devices with a largely bounce-free switching action are a prerequisite for proper functioning of contactor control. This requirement is met by the switchgear in the following. The double master controllers are easy and reliable to operate. They have switching elements actuated by cam discs. The switching elements are available in two versions: With gold-plated switching contacts for reliably switching low voltages and currents as well as currents of up to A and voltages of up to 0 V at AC- With silver contacts for currents of up to A at AC- 0 V. Easily sensed detent positions and a particularly emphasized zero detent allow reliable switching, even in forceful operation. Built-in switch for one or two directions of movement for crane controllers Switching elements with gold-plated contacts, suitable for electronics Choice of switching elements with silver contacts for currents of up to A at AC- 0 V Pushbutton and latch function in the switching lever Analog setpoint generators can be fitted Opto-electronic encoders (digital master controller) can be fitted Grab differential limit switch SJ Rugged cam-operated switch in a cast housing For grab cranes with single-lever grab control Actuation of the differential limit switch by the closing and holding winch SJ with grip SJ with ball SJ with pushbutton in the ball Applications Mounting Double master controllers SJ are intended for building-in in degree of protection IP 00. They are suitable for fitting in: Crane control gear, control stands and control pedestals Stationary and portable consoles Remote and floor-control units The controllers are suitable for switching auxiliary circuits of up to 0 V at AC-. The double contact principle and gold-plated switching contacts also ensure reliable switching at low voltages in electronic circuits. The duplex master controller is screwed on to the upper cover plate of the mounting space from the exterior with four screws. The plate on which the controller is secured should have a thickness of to not more than mm. The mounting opening is sealed with a bellows. This has a molded seal at the bottom fold which is clamped between the cover and the housing. The bellows is made of highly flexible neoprene and resists oil, acids, caustic solutions, sea water, ozone and UV radiation. / Siemens HE. 999

3 Switchgear and control equipment Drive block The drive block has a switching lever and an internal articulated-shaft mechanism, with which two drive axles can be actuated independently, separately or jointly. The drive axles are offset by 90. Each drive axle can be actuated from each switching position of the other axle. The switches for surface mounting on the side are driven via gear segments and spur gears; the switch fitted to the base is driven via bevel gears. At the drive block, surface mounting switches can be fitted to one or both mounting surfaces of each drive axle. A surface mounting switch can also be fitted to the base on which one of the two drive axles acts. However, not more than switching elements may be arranged on one drive axle. The number of mounting surfaces which can be occupied by switches is reduced if spring return devices are used or a surface mounting switch is to be fitted to the base. The detent disc is part of the surface mounting switch and has an emphasized zero detent. The drive block is available in two different versions: Normal version for a service life of million switching operations Ruggedized version for a service life of 0 million switching operations. Switching lever A grip or ball is fitted to the switching lever as the actuating element. Grey grip without momentary-action function with pushbutton with latch for zero position locking with latch as pushbutton. Black ball without momentary-action function with pushbutton with dead man pushbutton (mechanical by keeping the upper half of the grip pressed down, or capacitive by resting the hand on it) with signal switch (by raising the lower half of the grip) with mechanical zero position locking (by raising the lower half of the grip). The grey grip can be rotated 90 to each side after slackening a nut. A pushrod positioned within the switching lever actuates a microswitch situated in the interior of the drive block. To allow the microswitch to be actuated from each switching position, the pushrod has a ball segment at the lower end. The zero position locking is also actuated via the pushrod. The switching rod travels largely wear-free in a gate with two guide rolls. The lever excursion is restricted to 0 on each side. The stop plate can be replaced or exchanged for a special switching gate. Double lever-operated mechanism For special applications. N O N HE- Surface mounting switch for SJ Cam disc for SJ Surface mounting switch of a SJ with wire-wound potentiometer with detent Surface mounted switch The surface mounted switch is assembled from switching elements, each with two contact elements, which are snap-fitted on a support. The switching elements have special double contact elements of high reliability and are available in two versions: For currents A as standard version (grey color). These switching elements have gold-plated contacts and can also reliably switch low currents in the ma region at low voltages. They are therefore also suitable for use in electronic circuits. For currents up to A (yellow color). These switching elements with silver contacts should be used for switching currents of > A (such as contactors of other manufacturers). The control state indicators on the switching elements indicate the control state of the individual contacts. Assemblies of,,,, and contacts can be created. The conductor terminals use the SIGUT connection system and have the following technical advantages: - Captive screws - Funnel-shaped conductor and screwdriver guides - Safe from touch by finger and back of hand to DIN VDE 0 Part 0.

4 Cam disc A cam disc is assigned to each contact element. The cam discs are clamped onto the camshaft with cup springs. After removal of the double switching element, they can easily be replaced with a wire hook supplied with each switch. The detent element is fitted to the side opposite to the drive side. The detent disc allows up to -0- switching positions and has recesses to emphasize the zero detent which can thus be clearly distinguished from the switching positions. The detent spring can be replaced and is available in three strengths so that the detent can be adapted to the operational requirements. The cam discs are marked on onesidewith N fornonoverlapping contacting and on the other side with U for overlapping contacting. With the programs cut at the factory, the N marking always points to the drive side. The cam discs have markings allowing the switching program to be cut with a fine saw and file. The cam discs must be seated on the switching shaft in such as way that the same marking is always seen in the viewing direction. Spring return Fitting of potentiometers or digital encoders Friction brake Spring returns can be fitted to On variable-speed drives, Opto-electronic encoder A mechanical friction brake the opposite mounting surface of the switch for auto-return of potentiometers or digital encoders are used to preset the (OEE) GA 0-@AA00 with linear characteristic can be installed to achieve greater friction force.
