2 Limit switches Position product description Position Limit switches page 36 to 42 The position (rotary-angular) limit switch is used to control several handling system: sophisticated crane system: the unit controls power operating system (ex. PLC) and allows the crane to slow-down and/or to stop running. hoist: the unit is used to stop the hoist running whenever it reaches a limit position Different combinations available for all standard system. Customization available on request. How it works? moving device As an example, an FCR6 is typically used on a sophisticated crane system. Its function is to control the crane as it approaches operational limits in the following sequence: With the crane moving forward the end position, the FCR6 controls the crane s reducing the (first step) than stopping the crane (second step). In this position the forward command is no longer enabled. Only the reversing command is enabled for operation, in the first than in the second. Picture shows a FCR working on a crane system 36 Example FCR6 FORWARD 1 step reduce the 2 step stop the system REVERSE Go in first than, asap the FCR change pos., in the second Picture shows a FCP working on a hoist
