ESG 2.4
E - Delay on
Control by Us via K1. After closing of K1, the adjusted time
begins to run. After expiry of this time the output relay
switches to its active state and stays in working mode until K1
is again opened. An interruption of Us during a time t causes
a reset.
A - Delay off
Us is permanently connected via K1. Control via the control
contact K2. After closing of K2 the output relay switches
immediately. If K2 is again opened the adjusted time t starts
to run and after expiry of the time t the relay output returns
to its initial position. The closing of K2 during the time t
causes a time reset and the sequence restarts after a new
opening of K2 again at zero.
B2 - Cycling timer starting on a pause
Control by Us via K1. After closing the K1 the adjusted time t
begins to run. After expiry of this time the output relays
switch to their active state and are activated in a 1:1 pulse/
pause ratio as long as K1 stays closed.
S1 - Stop monitoring
Us is permanently connected via K1. Control via the control
contact K2. The output relay switches immediately, indepen-
dently of K2 and after that the first positive edge of K2 starts
the time t. Each additional positive edge of K2 which arrives
before the expiry of the time sequence starts the time t again
and the output relay stays in active mode. After expiry of the
time t the output relay returns in its initial position and the
unit is interlocked against all following edges of K2 (memo-
ry). The sequence can only be restarted by a new opening
and closing again of K1.

I1 - Pulse limitation timer voltage control
Control by Us via K1. After closing the K1 the output relay
switches immediately and the adjusted time t begins to run.
After expiry of the time t the output relay returns to its
passive state. An interruption of Us during the time t causes
a reset.
I2 - Pulse extension with control contact
Us is permanently connected via K1. Control via the control
contact K2. After closing the K2 the output relay switches
immediately and the adjusted time t starts to run. After
expiry of the time t the output relay returns to its initial
position. During this time t, K2 can be actuated as many
times as required. Another cycle can only be started if the
actual one is terminated.
W2 - Wiping on trailing edge
Us is permanently connected via K1. Control via the control
contact K2. To set the relay in operation mode K2 has to be
closed. At the opening of K2 the output relay switches
immediately and the adjusted time t starts to run. After
expiry of the time t the output relay returns to its initial
position. During the time t K2 can be actuated as many times
as required. Another cycle can only be started if the actual
one is terminated.
E1 or E - Delay on with control contact
Us is permanently connected via K1. Control via the control
contact K2. After closing (E1) or opening (E) the K2 the
adjusted time t starts to run. After expiry of the time t the
output relay switches to operation mode and stays in the
position until K2 is opened again.
