Temperature Switch TS 2125
examples fOr The acTIOn Of The relay 1:
Relay 1 will be switched ON if:
T1≥ T1 ON(min) and T1≥(T2 + Difference)
Relay1 will be switched OFF if:
T1 ≤ (T2 + Difference – Hysteresis) OR T1 ≤ (T1 ON(min) – Hysteresis)
example n1:
Input:
Difference = 5
Hysteresis= 2
T1 ON(min)= 15
T2 ON(max) = 70
Measured value:
T2= 20
Relay 1 ON is
T1 = 25
Relay 1 OFF is
T1= 23
example n2:
Input:
Difference = 5
Hysteresis= 2
T1 ON(min)= 30
T2 ON(max) = 70
Measured value:
T2= 20
Relay 1 ON is
T1 = 30
Relay 1 OFF is
T1= 28
examples fOr The acTIOn Of The relay 2:
Relay 2 will be switched ON if
T2 ≥ T2 ON (max)
Relay 2 will be switched OFF if
T2 ≤ (T2 ON (max) – Hysteresis)
Beispiel n3:
Input:
Difference = 5
Hysteresis= 2
T1 ON(min)= 30
T2 ON(max) = 70
Measured value:
T2= 20
Relay 2 ON is
T2 = 70
Relay 2 OFF is
T2= 68
