Setting the functions on the device

Overview of functions of the 3RP2505 multifunctional timing relay

Two setting options for implementing the multifunctions (A-M):

Extended function variance by selecting the time range and determining,

whether 2 CO switch in parallel or

whether 1 CO switches with delay + 1 CO switches immediately (1 CO + 1 CO)

Determination of 13 functions by the setting A to M,

with 1 CO, 1 NO, 2 CO that switch in parallel.

Operation 4: Start contact B./A2 opens while delta time is running and is applied again The control supply voltage is applied to A./A2 and there is no control signal on B./A2. This starts the *Δ timing.
