---|---|---|---|---|---|---|
spool_total_travel_wlimit | 4017 | Total Spool Valve Travel | Warning limit for the Spool Total Travel counter. Exceeding this value will generate a warning. | R/W | Float | 2049 |
spool_reversals_wlimit | 4018 | Total Spool Valve Reversals | Warning limit for the Spool Reversals counter. Exceeding this value will generate a warning. | R/W | Unsigned | 2049 |
steady_state_dev_wlimit | 4019 | Steady State Deviation | Warning limit fot Steady State Deviation. Steady State Deviation is used to determine the basic control accuracy of the valve. It is updated whenever the setpoint is considered to have reached the desired position as precisely as possible. | R/W | Float | 2049 |
dynamic_state_dev_wlimit | 4B02 | Dynamic State Deviation | Warning limit for Dynamic State Deviation. Dynamic State Deviation can be used to estimate valve dynamics such as response times. It is updated whenever the setpoint changes and the valve is expected to move accordingly. Updating continues throughout the valve movement and is switched back to Steady State when both setpoint and valve position have reached a steady state. | R/W | Float | 2049 |
stiction_low_wlimit | 4B03 | Stiction Low | Lower warning limit for Stiction. You can use the Stiction value to estimate internal frictions in the control valve package: Increased stiction suggests an increase in internal friction, which can cause accuracy problems and ultimately prevent the valve from moving. Decreased stiction suggests a decrease in internal friction. This may indicate problems such as extensive wear or valve shaft break. | R/W | Float | 2049 |
stiction_high_wlimit | 4B04 | Stiction High | Upper warning limit for Stiction. You can use the Stiction value to estimate internal frictions in the control valve package: Increased stiction suggests an increase in internal friction, which can cause accuracy problems and ultimately prevent the valve from moving. Decreased stiction suggests a decrease in internal friction. This may indicate problems such as extensive wear or valve shaft break. | R/W | Float | 2049 |
load_for_open_low_wlimit | 4B05 | Load for Open Low | Lower warning limit for Load for Opening. You can use Load for Opening to estimate the following: 1) Seat wear, especially in butterfly valves 2) Medium crystallization in e.g. ball valves. The Load for Opening trend is updated whenever the valve is opened from a fully closed position. Like stiction, this trend is based on the pneumatics measurement. | R/W | Float | 2049 |
load_for_open_high_wlimit | 4B06 | Load for Open High | Upper warning limit for Load for Opening. You can use Load for Opening to estimate the following: 1) Seat wear, especially in butterfly valves 2) Medium crystallization in e.g. ball valves. The Load for Opening trend is updated whenever the valve is opened from a fully closed position. Like stiction, this trend is based on the pneumatics measurement. | R/W | Float | 2049 |
steady_state_dev_alimit | 4020 | Steady State Deviation High Limit | Alarm limit for Steady State Deviation. Steady State Deviation is used to determine the basic control accuracy of the valve. It is updated whenever the setpoint is considered to have reached the desired position as precisely as possible. | R/W | Float | 2049 |
steady_state_dev_latch_time | 4021 | Steady State Deviation Latch Time | Time value in seconds for the Steady State Deviation alarms. The measurement must remain out of the limits for the time period indicated by the latch time value. | R/W | Float | 2049 |
