Mode of Operation
Function Aa - Asymmetri-
cal Recycler ON-time peri-
od first
The relay operates and the
ON-time period (T1) begins
as soon as the power supply
is connected. After the ON-
time period the relay releas-
es for the OFF-time period
(T2). This sequence contin-
ues until the power supply is
interrupted for at least 200
ms.
Function Ab - Asymmetri-
cal Recycler OFF-time
period first
The OFF-time period (T1)
begins as soon as the power
supply is connected. After
the OFF-time period the
relay operates for the ON-
time period (T2). This
sequence continues until the
power supply is interrupted
for at least 200 ms.
Function Sh - One shot
time function
The OFF-time period (T1)
begins as soon as the power
supply is connected. After
the OFF-time period the
relay operates for the ON-
time period (T2). After the
ON-time period the relay
releases and does not oper-
ate until the power supply is
interrupted for at least 200
ms and connected again.
Function Dt - Two state
delay on operate (2 x
SPDT versions)
The first time period (T1)
begins as soon as the power
supply is connected. At the
end of the first time period
the first relay operates and
the second time period (T2)
begins. At the end of the
second time period the sec-
ond relay operates. Both
relays release when the pow-
er supply is disconnected.
