Pumped volume is calculated at the end of the pump cycle. Totalized volume given through
a relay set up for totalizer [Relay Function (2.8.1.4.) (Page 195) = Totalizer] will be given in
bursts at this time.
Both the open and closed times for the relay contact are provided by Relay Duration
(2.10.1.3.) (Page 211) and are preset to 0.2 seconds. Partial units are added to the next
pump cycle.
A relay set up to make one contact for every cubic meter (m
3
) of liquid.
Relay Duration (2.10.1.3.) (Page 211)
To set the totalizer to provide relay contact to an external counter, use the following:
1 Contact per 10
Multiplier (2.10.1.2.)
units Multiplier (2.10.1.2.) (Page 211) is preset to 0 so the default
number of contacts for a pumped volume cycle is equivalent
to the number of volume units.
The source of units depends on the operation:
OCM [Sensor Mode (2.1.3.) (Page 163) = Flow
Maximum Flow (2.13.4.3.) (Page 243) or Flowrate
Units (2.13.4.7.) (Page 245)
Pumped Volume [Sensor Mode (2.1.3.)
(Page 163) = Pump Totalizer]
Maximum Volume (2.7.3.) (Page 188)
