5.3.2 Menu "start delay"
The menu "start delay" is accessed via menu mains start delay. It shows the time for a start delay after a grid error or grid failure. The standard value is 0. Usually, there is no need to change this value. The value can be changed only if the service code has been entered.
CAUTION:
An incorrect value for start delay may reduce the energy yield of the turbine.
5.3.3 Menu "mains parameters"
The menu "mains parameters" is accessed via menu mains mains parame-
ters. The menu has the following structure:

By pressing the keys select up / select down individual parameters can be selected. When a parameter has been selected, it can be changed within certain limits, provided the service code has been entered. For changing, the keys parameter
up / parameter down and standard parameters are used. By means of the key pre-
sent parameter you can change back to the original value. By pressing accept pa-
rameter the new value is confirmed and stored.
CAUTION:
Incorrect grid parameters can endanger the safe operation of the turbine on the utility grid or reduce the yield of the turbine.
