OPERAND DESCRIPTIONS:

Timer time - This tuning parameter specifies the time-out interval in minutes. Timer time values

are: 0, or 0.0042 to 8,921,000 for the 4 hertz version controller; 0, or 0.0016 to 3,568,400 for the 10

hertz version controller; and 0, or 0.0009 to 1,784,200 for the 20 hertz version controller.

Reset signal - The name of the general register or discrete loadable function that contains the

reset value (1 = reset, 0 = normal).

Comment - A comment up to 255 characters long.

FUNCTION EQUATIONS:

If SVD(in) > HD, and Reset value = 0 {a 0 to 1 transition of SVD(in)}

1. HA = Timer time

If SVD(in) <= HD, and reset value = 0 {no 0 to 1 transition of SVD(in)}

2. HA = HA -

Dt, HA limited to >= 0

If SVD(in) <= HD, and Reset value = 0 {no 0 to 1 transition of SVD(in)}

3. HD = SVD(in) last cycle

4. SVA(out) = HA

5. SVD(out) = 1, If Reset value = 0 and HA > 0

6. SVD(out) = 0, If Reset value = 1 or HA = 0

7. On power up or if reset value = 1:

SVA(out) = HA = 0

SVD(out) = 0

HD = SVD(in)

Where: HD = discrete hold value (SVD(in) from last cycle)

Dt = sample time in minutes

Timer time = value specified in operand 1

Reset value = value specified in operand 2
