Mode of Operation
Function Aa - Asymmetri-

od first
The relay operates and the
ON-time period (T1) begins
as soon as the power sup-
ply is connected. After the
ON-time period the relay
releases for the OFF-time
period (T2). This sequence
continues until the power
supply is interrupted for at
least 200 ms.
