## Relay Life Span Page

### Overview
The "relay life span" page provides a monitoring system for the device's relays, counting the number of times each relay has been switched. This data is stored in permanent memory.

### Key Parameters
- **Switching Count Relay Life**: Sets the limit for the number of switchings. When this limit is exceeded, a warning is sent via the "switching count warning" object.
- **Switching Count Reset Object**: Enables or disables the "switching count reset" object, which resets the switching count to zero.
- **Switching Count Indication**: Activates the feature to send the switching count to the KNX bus. The frequency of this emission is set by the "switching count emission in every" parameter.
- **Switching Count Emission in Every**: Specifies how often (in terms of number of switchings) the switching count is sent to the KNX bus.
- **Switching Warning Indication**: Enables or disables the "switching count warning" object.

### Purpose
- To monitor the lifespan and usage of each relay.
- To provide warnings and indications related to relay usage.
- To allow for preventive maintenance and troubleshooting.

### Usage
This page should be accessed during the initial configuration in the ETS software and can be revisited for ongoing monitoring and adjustments.
