4.4.11. Status output
Description
(1) Output
Total pulse and status (measurement error or flow rate switch) output can be set as follows (common for
DO1/DO2/DO3)
1. NOT USED:
Contact output is not used.
2. SIGNAL
ERROR:
Outputs
when measurement error occurs.
3. F: TOTAL PULSE:
Outputs flow rate total pulse in forward direction.
4. R: TOTAL PULSE:
Outputs flow rate total pulse in reverse direction.
5. F: TOTAL ALARM:
Outputs when flow rate total alarm in forward direction is exceeded.
6. R: TOTAL ALARM:
Outputs when flow rate total alarm in reverse direction is exceeded.
7. F: TOTAL OVERFLOW: Outputs when flow rata total value in forward direction overflows.
8. R: TOTAL OVERFLOW: Outputs when flow rate total value in reverse direction overflows.
9. FLOW SW HIGH:
Outputs when the upper limit setting of the flow switch is exceeded.
10. FLOW SW LOW:
Outputs when the flow rate becomes lower than the lower limit setting of the flow
switch.
11. FULL SCALE 2:
Outputs when analog output operation range is full scale 2.
12. AO RANGE OVER:
Outputs when the value exceeds the upper limit setting or becomes lower than the
lower limit setting of the range.
13. PULSE RANGE OVER: Outputs when the total pulse output exceeds the maximum output frequency value.
14. R: FLOW DIRECTION: Outputs when the flow is in reverse direction.
15. DEVICE ERROR:
Outputs when devices become abnormal.
(2) Mode
The mode of status output pulse can be set as follows.
1. NORMAL:
Normal off (DO1/DO2) or normal open (DO3)
2. REVERSE
Normal on (DO1/DO2) or normal close (DO3)
CAUTION
•
If the mode is set to REVERSE, DO output is provided when the power is turned on. Check if DO
output can be modified before setting.
Note: DO output specifications
