In the circuit diagram above, I1 enables both analog value
comparators. If a value goes below the set value, A1 switches
output Q1. If another value exceeds the set value, A2
deactivates output Q1. A3 switches marker M1 on and off.

A1 Analog value comparator function relay 1
EQ Equal mode
The function relay has the following modes:
•
LT: less than
• LE: less than/equal to
•
EQ: equal to
• GE: greater than/equal to
• GT:greater than
+ + appears in the PARAMETER menu.
- does not appear in the PARAMETER menu
I1 Comparison value 1 (positive value I7, I8, I11, I12,
actual value T1 to T16, C1 to C16)
F1 Gain factor for I1 (I1 = F1 × actual value at I1); F1 =
positive value from 0 to 9999
I2 Comparison value 2 (positive value I7, I8, I11, I12,
actual value T1 to T16, C1 to C16)
F2 Gain factor for I2 (I2 = F2 × actual value at I2); F2 =
positive value from 0 to 9999
OS Offset for the value of I1 (I1 = OS + actual value at
I1); OS = positive value from 0 to 9999
HY Switching hysteresis for value I2
Value HY applies both to positive and negative
hysteresis.
•
I2 = Actual value at I2 + HY;
• I2 = Actual value at I2 - HY;
•
HY = Positive value from 0 to 9999
h
Work normally with analog inputs and setpoints as the
parameters for the analog value comparator.
