Flow rate meter present
Select the flow rate meter that is present for measuring the volume of water applied
per valve and monitoring the flow rate:
None: No flow rate meter is present.
Water meter: A water meter with pulse contact is present.
Flow meter: A flow rate meter (e.g. GF15) is present.
Flow rate factor 0 - 200
Flow rate meter: The K-factor of the flow rate sensor in pulses/litres.
Water meter: The flow rate factor of the litre counter in litres/pulses.
See also: "Central contact" on page 39.
Type of central contact
Select the type of central contact applicable.
Off: Execute a contact start when the contact opens.
On: Execute a contact start when the contact closes.
Over: Execute a contact start when the measured value rises above a preset
level.
Under: Execute a contact start when the measured value drops below a preset
level.
Central contact, smooth rate
The speed with which the measured value of the contact start measurement will be
raised or lowered. This value applies to all contact starts.
00:00:00: No smoothing will be applied.
00:10:00: Field value.
If the contact start measurement is a weight, for example, the measurement may
fluctuate when someone walks past the scales. To resolve such issues, this setting
enables the measurement to be smoothed.
EXAMPLE
Smooth rate 00:10:00 = 600 sec.
Actual measurement = 66.0 kg.
Previous weight measured = 60 (kg).
Controller cycle time = 10 sec.
New contact start value measured = 60.0 + ((66.0 - 60.0) x 10 sec) / 600 sec =
60.1 kg.
Assign valve to second group
No: A valve may be assigned to one group.
Yes: A valve may be assigned to two groups.
