Multifunctional clock-pulse generator relay
MFT T21S, MFT T51SE
TI/TP - Cycling timer relay beginning on a pulse /
Cycling timer relay beginning on a pause
Control by Us via K1. When K1 is closed the adjusted time t1
or t2 starts to run according to the function set (pulse or
pause starting). The output relay clocks in the adjusted
pulse/pause ratio as long K1 stays closed.
EA - Delay on and Delay off
Us is permanently connected via K1. Control via the control
contact K2. After closing the K2 the adjusted time t1 starts to
run. After expiry of the time t1 the output relay switches on.
At the opening of K2 the adjusted time starts to run and after
expiry of the time t2 the output relay returns to its passive
status.

EI1 - Delay on with pulse limitation
Control by Us via K1. Bridge between connections 2 and 5. If
K1 is closed the adjusted time t1 starts to run. After expiry of
the time t1 the output relay switches on and the adjusted
time t2 starts to run. After expiry of the time t2 the output
relay returns to its passive status. An interruption of Us
during the time t1 or t2 produces a time reset and the cycle
restarts from the beginning.
EI2 - Delay on with timed pulse
Us is permanently connected via K1. Control via the control
contact K2. After closing the K2 the adjusted time t1 starts to
run. After expiry of the time t1 the output relay switches on
and the adjusted time t2 starts to run. After expiry of the
adjusted time t2 the output relay returns to its passive
status. During the time t1 or t2 the contact K2 can be opera-
ted at any time. A new cycle can only be started after the
actual one is finished.
