Dwyer UTS - Manual (Page 10)

Setting the Series UTC Relay Values
You can set the relays to five different configuration modes: Level, Distance and
Flow (where applicable), Volume and Totalization (the last two modes should be
configured only after Volume/Totalization options were enabled in the Chapter 5,
Additional Features). Use NEXT or BACK buttons to toggle between modes and
ENT to select the mode. After selecting an indication mode, move on to set the first
relay parameters.
Relays Setup Options
For example, if the Series UT is set to flow indication mode, the relay can be set to
flow/distance or level values. In any other unit or SW version, the relay
configuration is done for level or volume values.
Each of the five relays in the Series UT allows you to define open and close values
for the switch, enabling its use for functions such as triggering an alarm or
controlling pumps.
In addition, relay four (4) can be configured to report error messages and relay five
(5) for flow totalization pulse setup (see detailed configuration instructions on page
10).
The relay values function as follows:
• Open value: (Default = 0) The relay opens if the level measured in the tank is
higher than the entered open value.
• Close value: (Default = 0) The relay closes if the level measured in the tank is
lower than the entered close value.
To Set the Relay Values for Level or Distance:
Relay values can be configured in two separate screens when set to flow, volume
or totalization (after setting the Series UT was set to of these indications).
As shown in the above example, relay values were configured in the following way:
000001 was entered in the high numbers H=1, and 20,000 was entered in the low
numbers L=20,000, which mean a total value of 120,000 gallons.

NOTES:
The indication mode default state is Level. The chosen mode will be applicable for
all five relays. The close value must be lower than the open value for each relay,
otherwise an message is displayed. An message is displayed if a
relay value is greater than the tank height value.
In case of no measurement (caused by electronic problem or acoustic
interference) relays will switch to Close state.
For safety reasons relays parameters will reset when the following parameters will
be modified: Tank height, relays indication mode (Level/ Distance/Flow),
measurement mode (except when changing from Level to Distance and vise
versa) Flume/Weir type, measurement units, strapping table.
