3. Use A1 to change the blinking digit. The setpoint is changed one digit at a time. A1
increments each individual digit (9 rolls over back to 0), while A2 is used for recording the
new digit value and selecting the next digit.
4. Use A2 to record the new value and select the second digit.
5. After the last digit is set, continue holding A2 until
“SEt” is displayed. If you want to
change the first digit again, do not hold A2. Momentarily press and release A2 and the first
digit starts blinking again.
6. When finished recording
the new setpoint (“SEt” is displayed), release A2.
Note 1:
Valid setpoint range is 0-100% of full-scale flow. If the alarm value is set higher than
full-scale, it is clamped at full-scale upon exiting this menu.
Note 2:
To disable the alarm, set its value to zero.
Note 3:
The red ALARM 1 LED comes on when flow exceeds this setpoint. This LED is in series with
the drive circuit for the high-alarm open-collector output, meaning that the output transistor is active
whenever this LED is on. Some models do not have any external wiring that connects to the alarm
transistor (see Model Codes).
In this example, the high alarm had been set for 80.0; therefore, the red LED was activated when flow
reached 80.1.
The LED turns off when flow < ( setpoint
– hysteresis). Hysteresis is 5% of full-scale.
