AU (Automatic) = fixed changeover
The S/W time changeover takes place using a preset calendar program,
which is programmed up to the year 2079 and cannot be modified.
(Legal summer time regulation of European Union and Switzerland)
Start of summer time: always the last Sunday in March.
The hour counter is moved forward by one hour from 2 to 3 o’clock.
End of summer time: Always the last Sunday in October.
The hour counter is moved back from 3 to 2 o’clock.
cHA (calculated semi-automatic) =
selectable changeover with weekday reference
The summer time start date that applies to your location/country is entered
(e.g. date of last Friday in April of current calendar year) and the summer
time end date (e.g. date of first Tuesday in October of current calendar year).
The program automatically assigns the correct weekday to these dates
(Friday or Tuesday in this case).
In subsequent years the time change always takes place on the calculated
Weekday, irrespective of the date (last Friday in April and First Tuesday in
October in this case).
HA (Semi-automatic) =
Selectable changeover with date reference
The summer time start and end dates that apply to your location/country are
entered. In subsequent years the time change always takes place on the same
date.
Activating automatic summer/winter time changeover
A prerequisite for the automatic S/W time changeover is entry of the current
date.
Note:
If the switch clock is switched to AM/PM, the month is set using the "h+"
button and the day using the "m+" button.
Operating Instructions
EM/2 digi 42
WA-EKF 80.10.1038.7
1. Starting Up
Electrical equipment should always be installed and assembled by a professional
electrician. (The term professional electrician is defined in VDE 0105).
Note:
The device contains well thought-out electronics. These electronics are protected
from most kinds
of external interference. However, it must be noted that the mains voltage can have
extremely high voltage spikes superimposed on it.
Problems also occur when switching contactors, which can affect an electronic
device in spite of all the internal protection measures. In order to provide as much
operational reliability as possible, attention should be paid to the following details
when connecting.
a) In larger systems safety coils switched directly by the clock switch
must be screened using a suitable varistor or RC module.
b) If inductive direct current consumers are switched, a free-wheeling diode must
be installed.
c) Inductive loads and especially fluorescent tubes put a particular strain on the
output contacts
In isolated cases, check whether the installation of a cutoff relay or contactor is
required.
