The simple operation and variable configuration of the safety and control functions guarantee quick error diagnostics with the installation and machine components.
The control relay easySafety is a TÜV certified all-rounder. The simple operation and variable configuration of the safety and control functions guarantee quick error diagnostics with the installation and machine components. Configuration is undertaken either directly on the device or on the PC using the easySoft-Safety software. It is possible to select between stand alone or integrated solutions in the easyNet network.
Safety functions: Stopping in an emergency (EMERGENCY-STOP disconnection) Eaton provides one and two-channel variants for the implementation of safety-oriented applications. The internal logic of the safety relays monitors the safety circuits (Emergency-Stop, safety door) and activates the enable paths when in a fault-free state. The enable paths are switched off after actuation of the safety devices or in the event of a fault. Faults which occur in the control circuit such as an earth fault, cross-short and open circuits are reliably detected. Activation of the enable path is prevented in the event of a fault.
Monitoring movable guards Accessible hazard areas must be secured. The position of the movable safety device is detected using position switches or non-contact sensors, which are monitored and evaluated by a secure logic unit. A risk assessment provides the necessary degree of risk reduction through the safety device.
Monitoring light curtains The access to dangerous zones is monitored by light curtains. An accidental or unallowed intrusion into dangerous zones is detected and evaluated by safety relays ESR.
Two-hand monitoring On machines which have a high potential for injury, both of the operator's hands must be located outside the hazardous area before the machine movement can be initiated. In order to protect the operator, the two-hand control must be operated with both hands simultaneously, within 500ms. This is necessary to operate the machine, and keep it in an operational state. Monitoring of the timing sequence is assumed by the ESR5-NZ-21-24VAC-DC, which can be used for two-hand controls, conforming to the safety requirements of category IIIC to EN 574.
