P3.13.6.2 UPPER LIMIT (ID 736)
P3.13.6.3 LOWER LIMIT (ID 758)
Set the upper limit and the lower limit around the reference. When the actual value is less or
more than the limits, a counter starts to count up. When the actual value is between the
limits, the counter counts down. When the counter gets a value that is higher than the value
of P3.13.6.4 Delay, an alarm or a fault shows. You can make a selection of the response with
parameter P3.13.6.5 (Response to PID1 Supervision Fault).
9.12.4 PRESSURE LOSS COMPENSATION
When you pressurise a long pipe that has many outlets, the best position for the sensor is in
the middle of the pipe (the position 2 in the figure). You can also put the sensor directly after
the pump. This gives the right pressure directly after the pump, but farther in the pipe, the
pressure drops with the flow.
