Delay off without supply voltage
MFT SA23S
Function descriptions
E - On delay
Activation by Us via K1. When K1 closes, the set interval t
begins (green LED U illuminated).
After the interval t has elapsed, the output relay picks up and
remains in the working position until K1 is opened again.
Interrupting Us during the interval t causes a reset.
A - Off delay
Activation by Us via K1. The output relay picks up after K1
closes. If K1 is opened again, the set interval t begins (green
LED U not illuminated).
After the interval t has elapsed, the output relay drops back
out to its rest position. Operating K1 during the interval t
causes a time reset.
I1 - Pulse limitation timer voltage control
Activation by Us via K1. When K1 closes, the output relay
picks up immediately and the set interval t begins (green
LED U illuminated).
After the interval t has elapsed, the output relay drops back
out to its rest position. This condition is maintained until Us
is interrupted. Interrupting Us before the interval t has
elapsed means that the output relay remains picked up until
the interval t has fully elapsed.
W2 - Wiping on trailing edge voltage control
Activation by Us via K1. The output relay remains dropped
out after K1 closes. As soon as K1 is opened, the output relay
picks up and the set interval t begins (green LED U not
illuminated).
After the interval t has elapsed, the output relay drops out.
Closing K1 before the interval t has elapsed means that the

output relay remains picked up until the interval t has fully
elapsed.
W3 - Wiping on leading and trailing edge voltage
control
Activation by Us via K1. When K1 closes, the output relay
picks up and the set interval t begins (green LED U lillumina-
ted).
After the interval t has elapsed, the output relay drops out.
As soon as K1 is opened, the output relay picks up and the
set interval t begins (green LED U not illuminated).
After the interval t has elapsed, the output relay drops out.
Interrupting or re-applying Us before the interval t has
elapsed means that the output relay remains picked up until
the interval t has fully elapsed.
