摘要： The output of the sensor (5) monitoring the machine is connected to a test circuit which generates test signals for the input of the sensor. The sensor output is monitored by two check circuits and compared with the input signal. This identifies faults in the sensor and in the control circuit. The monitoring circuit has built in redundancy for a foolproof evaluation system. The test signals can be generated by two control circuits for added fail-safe redundancy. USE - Safety proximity controls protecting machine operatives.

摘要： The processing is carried out by members with logic base functions such that the output signal corresponds to a logic function, while the binary signals are transmitted between the members by light beams. The input signals from each generator are supplied to photosensitive components and/or voltage dependent light emitting components of the members. The binary output signal as a current or voltage signal with a defined level starts (in)directly the operation of a device, which dangerous if inadvertently operated. To a second binary level of the output signal corresponds the rest state of the device. The transmitted signals are in such logic coupling that on interference of the light transmission all components remain on the rest level. USE/ADVANTAGE - For control and monitoring circuits for machines and industrial processes, simple design for high security on failure of respective components.

摘要： A main fixed housing sleeve provides a location for the push-button assembly. This has a top section that engages a sleeve under spring bias. The contact of the bulb engages a sleeve and this locates in a carrier. When the push-button is actuated the carrier moves downwards against a spring and engages fixed contacts that connect with conductors. A centre pin has a dowel that moves in a latching track to retain the unit in the actuated state.

摘要： The module fitted in an opening in a front control panel has a holder (34) securing the contact and/or lamp, (35) with the head (10) of the module projecting through the panel opening. The holder (34) has an axial bore (38) receiving the rear end (30) of the head (10), with two locking devices cooperating with locking apertures (33) around the outside surface of the inserted end (30). Each locking device is moved out of engagement with the locking aperture (33) via an axially displaced bolt. Pref. the locking devices comprise spring wires clamped at one end, the other end fitting into a guide in the axially displaced bolt.

摘要： A safety circuit is proposed which is linked to an extension circuit. The safety circuit and extension circuits each have three positively driven relays (K1A, K2A, K3A), the signal take-off for the relays of the extension circuit being carried out on the relays of the safety circuit.

摘要： The apparatus (38) is connected to sensors (20,22) and/or actuators (24-30) and analyses, processes and controls their states. The apparatus is connected to the control (36) and transmits to it, in dependence on the state of the sensors and/or actuators, at least one release signal to enable at least one action in the manipulator (10). The execution of this action is monitored by the monitoring and control apparatus (38). In the case of a fault, at least one further signal is generated to bring the system into a safe state. Independent claims also cover a method of monitoring the system.
