Multiplier (2.11.4.2.)
Use to scale the external sampler up or down as required.
Values
This allows the totalizer relay to click for different values of volume.
Example:
To click once every 4310 units, set 2.11.4.2. Multiplier to 4310.
Interval (2.11.4.3.)
The time in hours from the activation of the relay until the next activation.
Values
Set the time to activate the relay during low-flow conditions.
Relay Duration (2.11.4.4.)
The time in seconds from one change of state in the relay to the next.
Values
This value must be less than the Interval (2.11.4.3.) (Page 221) or the relay will never reset.
Assigned Relay (2.11.4.5.)
Determines the relay assigned to flow sampler control.
Options
Relay Logic (2.11.4.6.)
Use to change the behaviour of the relay assigned to flow sampler control.
Options
Relay contact operation is NORMALLY CLOSED for alarms and NORMALLY OPEN for controls.
By default a control contact is Normally Open. For Interval (2.11.4.3.) (Page 221) the
corresponding relay coil is energized. By setting this parameter to Normally Closed, the relay
coil will be de-energized for the duration phase.
