Description
3.4 Special features
Special functions
● Function "flashing, asymmetrical": Pulse and interval can be adjusted separately. (clock-
pulse)
● Function "flashing, symmetrical": the pulse/interval ratio is 1:1. (flashing)
● With the "OFF-delay without control signal" function, timing is started when the time relay
is disconnected from the supply voltage.
● On the 3RP25 time relay with 7 switchable time ranges, there is a switch position ∞. This
means "continuous (unlimited) time". If this setting is selected with the "ON-delay"
function, the output relay never connects after the supply voltage is applied (OFF
function). With the function "passing make contact", the output relay always remains on
(ON function). This can be used for test purposes.
● If the control signal in interrupted when the "additive ON-delay with control signal"
function has been selected, timing stops and continues when the control signal is closed
again.
This function is not non-volatile and requires a continuous control signal supply.
● With the function "pulse-forming with control signal", an activated control signal triggers
an adjustable timing period. The control signal can be shorter or longer than the desired
operating time.
