5TT3185 multifunction timer

Setting aids

The period of the flashing of the green LED 1 when set for a timing interval is 1 s ± 4 %, which can therefore be used as a setting aid. This is particularly useful in the lower time setting range and for long delay times because the multiplication factors between the individual time ranges are exact.

Example:
Delay time to be set: 40 min.
Using the fine setting, this delay time can be set within the setting range 3 ... 300min. However, in this case it takes a long time to check the time and requires several operational sequences in realtime. To speed up the setting process, the setting range will be switched to 0.03 ... 3 min. In this case, the required value corresponds to a delay time 0.4 min (= 24 s). The timing interval is triggered and the potentiometer is set to 24 flashing periods of the yellow LED 2. The device is then set back to the setting range 3 ... 300 min and the setting process is completed.

Time operation interruption/time addition

For the functions AV, EW, IE, BI, the timing interval can be interrupted at any time by activating B1 (+) and by removing the control voltage continued again (time addition).

Control input B1

The functions RV, IF, AW, AV/RV can be controlled using the control input B1 (+) with potential against terminal A2. The auxiliary voltage of terminal A1 can be used for this purpose, as well as any other voltage within the range 12 ... 240 V AC/DC. The operation of parallel loads (e. g. contactors) from B1 (+) to A2 is also permissible.

If voltage is simultaneously applied to the control input B1 (+) and A1 for the IF function, this triggers an output pulse with the set time interval t₁.
