2 Specifications are subject to change without notice (19.06.07) 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 sup- ply is connected. After the ON-time period the r elay releases for the OFF-time period (T2). This sequence continues 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 pow- er supply is connected. After the OFF-time period the r elay operates for the ON-time period (T2). This sequence continues until the power supply is inter - rupted for at least 200 ms.
