7.2 Time setting multifunction unit
3RP2505 time relay
The time relay contains 1 or 2 CO contacts.
Time ranges
7 time ranges can be set with the time range selector switch:
● 0.05 s - 1 s
● 0.5 s - 10 s
● 5 s - 100 s
● 0.5 min - 10 min
● 0.05 h - 1 h
● 0.5 h - 10 h
● 5 h - 100 h
Operating time setting
The available time ranges are set using the time range selector switch, ensuring extremely
high setting accuracy. The set time range is indicated on the rotary switch. The desired
operating time is set precisely using an operating time adjustment switch. In the time range
"continuous" (∞), the function is implemented with an unlimited time setting. In the case of
"ON-delay" and applied supply voltage, the output relay never connects, for example, or with
"passing make contact", the output relay remains switched on continuously.
The selected function can be indicated legibly on the multifunction relay using the
appropriate stickers. You can find these stickers for labeling the set function in Section
"Attaching set of labels (multifunction) (Page 30)".
Note
Changes to the time range (time range and operating time) only take effect if made in the
deenergized state.
