Description

The Valve Positioner has the ability to read and convert the coil drive D/A convertor

output signal that drives HD22010-3 the valve. If the value readback (converted by the A/D

converter) and the value that was output do not match within a deadband, and for a

pre-defifined period of time, a severe fatal error is assumed. In this case, the Valve

Positioner is “flflying blind.” It cannot confifidently determine valve position or

control the output. The Valve Positioner will remove drive power (dive) from the

entire Electronics module’s FVP fifield card and go HD22010-3 through a reset sequence. The

coil drive D/A convertor readback check is a diagnostic that runs continuously.

Contingency is defifined as the difference between a target position and the actual

position, when that difference is greater than a defifined limit. In the Valve Positioner,

the contingency bit is set if the difference HD22010-3 exceeds a programmable limit (default

value is 5%) for a programmable time period (default value is 10 seconds).

Contingency is not a fatal condition.

An open coil is detected by measuring voltage across the current limiting resistors

on the servo output. When zero volts are detected, either the coil is open, the servo

output is at zero, or the mechanical bias on the servo valve is incorrect. When an

error condition is detected, an internal “open” bit is set.

Typically, the servo coil voltage is -200 mV when the valve is in a stable, controlled

position and the servo valve mechanical bias HD22010-3 is properly adjusted. If the servo output

amplififier voltage amplitude falls below 100 mV, the internal bit is cleared, as though

no error condition exists. If servo output voltage is greater than 100 mV, the

difference between servo output voltage and coil voltage is compared to 50 mV, and

if it is less, the ‘open’ bit is set.
