Note
The response of the plugs of all timers (input, reset) has been completely
changed to level-active for basic unit 1 from version *E05* and higher and
basic unit 2 from version *E03* and higher. Use of an unchanged parameter
file utilizing integrated timers may thus result in a different response if such
basic units are used. For example, if "Fixed level - '1'" is set at the timer
input, the timer function is automatically restarted after the timer reset
occurs. However, in timers with the parameterized type = "Fleeting closing"
there is no change in the response.
