Other data
| Note (applications) | safe standstill monitoring |
Notes
| Note (General) | Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit. |
Circuit example
| Note (Wiring diagram) | The wiring diagram is shown with guard doors closed and in de-energised condition. The ISD tables (Intergral System Diagnostics) for analysis of the fault indications and their causes are shown in the appendix. To monitor one guard door at plants with dangerous run-on movements up to PL d and Category 3 Standstill monitoring for unlocking solenoid interlocks The solenoid interlock can be opened, when the fail-safe standstill monitor has detected the end of the run-on movement by means of two inductive proximity switches. When the button (E) is actuated, the coil of the solenoid interlock is energised. For suitable IFL range p-type inductive proximity switches, refer to 'Schmersal Catalogue Automatisierungstechnik'. If only one inductive proximity switch is connected to the standstill monitor, the standstill frequencies must be identical and inputs X2 and X4 must be bridged. |
