1 The sensor reads a value and sends a corresponding signal (Volts) to the TV-VVTBP-E2's physical input. The
Analog Input microblock uses the Min and Max values to linearly translate the signal into the engineering value
used in subsequent control logic.
2 You can set up a custom translation table (page 49) on the driver's Custom Translation Tables pages in the i-
Vu® interface.
3 The control program must have one Pulse to Analog Input microblock for each pulse counting input.
4
The special binary input indicates a communication loss to the airflow sensor. You can use this in your control
program to select the actuator movement in the case of flow sensor fault. Sensor reconnection is detected
automatically and a power cycle is not required. In the microblock popup, under
Hardware Configuration , set
Expander to 0 , Input Number to 110 , and I/O Type to Special . To detect a flow sensor fault on the ZASF-A, use
Input Number 111 .
