摘要: A modular emergency stop device including a switch unit and a control unit. The switch unit includes a switch which converts from a normal state to an emergency state when an emergency stop is necessary and a housing for the switch. The control unit includes a controller which controls a power source for a machine and a housing for the controller. The switch unit's housing and the control unit's housing are adapted to be selectively coupled together and uncoupled from each other. The switch is operably coupled to the controller when the housings are coupled together whereby the controller may appropriately control the machine's power source when the switch is converted to the emergency state. To replace the switch, the switch's housing is uncoupled from the controller's housing to remove the switch unit and a new switch unit is coupled to the controller's housing.

摘要: A safety relay configuration for linking a power source to a device to be powered via at least one output wherein output contacts all have to be closed to provide power to the device, the configuration including first and second three contact relays or four contact relays, each relay including a first NC contact and at least two NO contacts and, wherein the second relay first contact is linked in parallel with the first relay second contact forming a first parallel configuration, the first relay first contact is linked in parallel with the second relay second contact forming a second parallel configuration, the first parallel configuration is linked in series with the first relay coil between the power source and ground, the second parallel configuration is linked in series with the second relay coil between the power source and ground and the relay third contacts are linked within the outputs between the power source and the device. Where the relays have four contacts, the relay fourth contacts are linked within the outputs between the power source and the device.

摘要: A method and system for diagnostic coverage of safety components monitors the state of a safety chain and each of the safety devices in the chain. A fault condition is detected if one of the safety devices indicates that the safety chain should be open but the safety chain indicates that it is closed. In order to prevent an inadvertent reset of the fault condition by opening the safety chain via a second safety device, the fault condition is latched until the monitoring system verifies that the faulty safety device has been corrected.
摘要翻译: 用于安全部件诊断覆盖的方法和系统监视安全链条和链条中每个安全装置的状态。 如果其中一个安全装置指示安全链应该打开,但是安全链表示它是关闭的,则检测到故障状况。 为了通过第二安全装置打开安全链来防止故障状态的无意中复位,故障状态被锁定,直到监控系统验证故障安全装置是否被校正为止。
