3RP25 Time Relays

Manual, 09/2019, A5E31947765002A/RS-AC/003

Function setting

2 functions can be selected for time relays of this type. Depending on the function required,

the left or right display must be pre-selected.

Work step

Process description

①

Turn the time range and function selector switch to

the desired time range with a screwdriver. Due to

the choice of the two functions, the time ranges

are arranged to the left and right respectively.
left (function N) = OFF-delay without control signal
right (function O) = positive passing make contact

without control signal

②

Turn the operating time adjustment switch for fine

adjustment to the required value.
