Functional description

Function A
t
Time relay with delayed response time.
When feeding the control voltage, a certain
period of time begins to pass, and at the end
of this time period the make contact changes
from 15-16 to 15-18. After an interruption, the
time period begins to pass again.
Function D
t
t
Time relay with delayed response and
release time.
When feeding the control voltage, a certain
period of time begins to pass, and at the
end of this time period the operating contact
changes from 15-16 to 15-18. If the control
voltage is interrupted then, a further time
lapse starts which is as long as the first
one. At its end the operating contact returns
to neutral position 15-16. After an interrupti-
on of the delayed response time, th period
of time begins to pass again.
Function G
t
Pulse shaper.
When feeding the control voltage, a certain
period of time begins to pass, and at the end
of this time period the operating contact
changes from 15-18 to 15-16.

t1
Time relay with delayed response time,
additive.
If the sum of control voltage interruptions is
equal to the adjusted time, the operating
contact will close. The operating contact
remains closed until the distribution voltage
is disconnected.
Function E
A1/A2
Y1
15 - 18
Time relay with flashing indicator, starting
with impulse.
As long as the control voltage is fed, the ope-
rating contact changes between 15-16 and
15-18. When feeding the control voltage, the
operating contact immediately changes to
15-18.
Function H
A1/A2
Y1
15 - 18
Wiping contact relay.
When feeding the control voltage, the make
contact
15-18 and returns after the wiping time has
passed. In case of cutting off the control volt-
age during the wiping time, the make contact
immediately returns to 15-16, and the
remaining time is deleted.
If the control voltage is interrupted then, a
further time lapse starts which is as long as
the first one. When feeding the control vol-
tage during the wiping time, the operating
contact immediately returns to 15-16, and
the remaining time is deleted.
Wipe contact flick contactor, additive.
A1/A2
When the distribution voltage A1-A2 is connected and the control voltage is fed, the operating con-
Y1
tact changes from 15-16 to 15-18. If the sum of control voltage interruptions is equal to the adjust-
ed time, the operating contact will open and can only be closed after a voltage cutoff.

Function C
t
Time relay with delayed release time.
When feeding the control voltage, the oper-
ating contact changes from 15-16 to
15-18. By interrupting the control voltage a
certain period of time begins to pass, and at
the end of this time period the operating
contact returns to neutral position 15-16.
Function F
t t
Time relay with flashing indicator, starting
with break.
As long as the control voltage is fed, the
operating contact changes between 15-16
and 15-18. When feeding the control volta-
ge, the operating contact remains at 15-16
for the time being.
Function K
t
Wipe contact flick contactor.
When feeding the control voltage, the make
to contact changes
15-18 and returns after the wiping time has
passed. In case of cutting off the control
voltage during the wiping time, the operat-
ing contact immediately returns to 15-16,
and the remaining time is deleted.
