Chapter 4 ________________________________________________________________ Operation Operation of Relays Quantity For Relay Output A relay monitors the quantity chosen for the relay output. Any of the quantities available can be chosen. Measurement-Based Relay Output Modes Relay Setpoints When the measured value is in between the "above" and "below" values, the relay is passive.
User's Guide ______________________________________________________________________ 0610-076 Figure 41 Relay Output Modes Mode 4 is usually used if an alarm needs to be triggered when the measured value exceeds a safe range. The relay is active when measurement is in range, and is released if the value goes out of range or the measurement fails. NOTE If the measurement of the selected quantity fails or the barometer loses its power, the relay is released.
Chapter 4 ________________________________________________________________ Operation NOTE If both setpoints are specified and the "above" setpoint is lower than the "below" setpoint, the hysteresis works in the opposite direction, that is, the relay is released when the measured value passes the exact value of the setpoint. Relay Indicating Barometer Error Status You can set a relay to follow the operation status of the device.
User's Guide ______________________________________________________________________ 0610-077 Figure 42 FAULT/ONLINE STATUS Relay Output Modes FAULT/ONLINE STATUS relays are usually used in conjunction with an analog output to obtain validity information for the output value. NOTE If a barometer loses its power, all status-based relays are released similarly to the case of an instrument failure.
