Enter here the time interval for the regular proof test. The entry must be in units of years.

The decimal separator is a comma. However, you can also enter a period. This is automatically converted into a comma.

Example: The safety function is checked every 18 months.
In this case, a value of 1.5 years must be entered for T_1.
Input: 1,5 or 1.5

Enter here the time interval for the regular proof test. This test will detect as many errors as possible that were not detected by the automatic diagnosis. The percentage of errors detected by the test appears in the PTC field. The entry must be in units of years.

Input: 1,5 or 1.5

Specify here the time intervals at which the safety function is checked in full. For example, a request can be viewed as a full test, but a device replacement or a 100 % inspection are also possible here. Please enter for T_2 the smallest of the three time intervals „average demand rate“, „useful lifetime“, and „full test“. The entry must be in units of years.

The decimal separator is a comma. However, you can also enter a period. This is automatically converted into a comma.

Example: The components of the safety function are replaced with new components after 12 years at the latest. A full test never takes place. Experience has shown that the safety function is requested once every five years. In this case, a value of five years must be entered for T_2.

Input: 5
