Settings on electronic circuit boards

Electronic circuit boards of the ER variants standard, D, VZ, VZ 15, G, GVZ and F have no setting options.
Electronic circuit boards of the ER variants I, VZC, H, RC can be set as follows.
Tolerance for time details max. + 20 %.
Units with time delay switches (VZ, VZ 15, GVZ, VZC, F, I, RC and H fans) have resistance to interference in line with EN 55014-2 (depending on pulse type and energy component 1000 to 4000 V). These values can be exceeded when operating with fluorescent tubes. In this case, additional interference suppression measures (L, C or RC modules, protection diodes, varistors) are required.

Setting

Place fan insert on front so that electronic circuit board (control) is freely accessible.
Set the desired values with the potentiometers as described below.
