Flow Sampler - Siemens SITRANS LUT400 Operating Instructions Manual

General Operation
7.10 External Totalizers and Flow Samplers
Parameter
Enable (2.11.3.1.) (Page 215)
Multiplier (2.11.3.2.) (Page 215) 4310
Relay Duration (2.11.3.3.)
(Page 216)
Assigned Relay (2.11.3.4.)
(Page 216)
Relay Logic (2.11.3.5.)

Note
Ensure proper counting output
In case of running totalizers when a change is required, cycle the power to ensure proper
counting output of the relay between parameter settings.
7.10.3

Flow Sampler

Use the External Sampler (2.11.4.) (Page 216) function to activate the flow sampler relay
based on volume and time.
Counter Formula
1 contact every x units, where x = value set
in Multiplier (2.11.4.2.) (Page 217)
Example: To click once every 4310 units, set Multiplier (2.11.4.2.) (Page 217) to 4310.
The totalizer source, and units depend on the volume configuration:
Volume Configuration
Vessel Shape (2.6.1.) (Page 180) =
NONE
Vessel Shape (2.6.1.) (Page 180) =
any setting other than NONE
By using Multiplier (2.11.4.2.) (Page 217), the relay contacts can be based on a volume
other than a multiple of ten.
Parameter
Enable (2.11.4.1.) (Page 216)
Multiplier (2.11.4.2.) (Page 217) 4310
Interval (2.11.4.3.) (Page 217)
Relay Duration (2.11.4.4.)
(Page 217)
120
Value Description
Enabled Enables External Totalizer Relay
Click once every 4310 units
0.2 Activates the relay for 0.2 seconds
Relay 1 Sets relay 1 to be controlled by external totalizer
Normally Use (if necessary) to change the behaviour of the
Closed relay assigned to the totalizer.
Default: Normally Open
Multiplier (2.11.4.2.) (Page 217) is preset to 1 so the
default number of contacts for a pumped volume cycle
is one contact per unit of volume.
Totalizer Source
Totalizers (2.16.)
(Page 237)
Totalizers (2.7.3.)
(Page 194)
Value Description
Enabled Enables Flow Sampler Relay
Click once every 4310 units
2 Sets the INTERVAL (in hours) of the relay con-
tact, usually long.
0.2 Sets the DURATION (in seconds) of the relay
contact, usually short.
