Window monitoring (digital units only)
Once the temperature has reached the upper threshold J1, the
output relay K1 changes its output state as soon as the set time t
has elapsed. The relay returns to its original state as soon as the
temperature reaches the set hysteresis value.
K2 responds in the same manner to the lower threshold of J2.
Closed-circuit principle
J
Principle of operation with memory function (3RS10 42,
3RS11 42), based on the example of temperature
undershoot using the closed-circuit principle
Once the temperature has reached the set threshold J1, the
output relay K1 changes its output state as soon as the set time
t has elapsed (K2 responds in the same manner to J2). The
relays only return to the original state when the temperature falls
below the set hysteresis value and when terminals Y3 and Y4
have been briefly jumpered.
