1.1 FEATURES AND APPLICATIONS
The Model 30 transmitters offer the choice of single
or dual sensor input with measurement choices of
pH/ORP and dissolved oxygen.
Dual measurement analyzers offer a wide choice
of measurement combinations thus reducing the
cost per loop and needed panel space.
FIELD COMMISSION OPTION: The Model 30 can
be ordered with the ability to commission measure-
ments in the field. This added flexibility can greatly
reduce the number of spare instruments required
for field servicing.
QUICK START PROGRAMMING: Exclusive Quick
Start screens appear the first time the Model 30
is powered up. Screen prompts direct the user to
register the number of sensors, the measurement
unit(s) and the language to display. Some measure-
ment specific prompts are also displayed. The
measurement loop is ready for use in a matter of
minutes.
MENUS: Menu screens for calibrating and register-
ing choices are simple and intuitive. Plain language
prompts guide the user through the procedures.
There are no service codes to enter before gaining
access to menus.
DUAL SENSOR INPUT AND OUTPUT: The Model
30 accepts single or dual sensor input. The two 4-
20 mA outputs can be independently programmed
to correspond to any selected measurement or
temperature. Output damping and linear or log
output may also be field selected.
ALARMS: The Model 30 has three fully program-
mable alarm relays that can be assigned to any
selected measurement or temperature. Alarms
can be configured as high, low, or USP 23
1
. The
third relay has the additional choice of fault alarm
operation. When selected, a fault alarm will activate
the relay when a sensor or analyzer fault occurs.
ENCLOSURE: The panel mount version fits stan-
dard ½ DIN panel cutouts, and its shallow depth is
ideally suited for easy mounting in Hoffman-type
enclosures. A panel mount gasket is included to
maintain the weather rating of the panel.
Surface/pipe mount enclosure includes self-tapping
screws for surface mounting. A pipe mounting
accessory kit is available for mounting to a 2-inch
pipe.
DISPLAY: The two-line, 16-character, back-lit dis-
play can be customized to meet user requirements.
All operations and descriptive messages can be
field selected for English, French, German, Italian,
Spanish or Portuguese. Informative screens, which
permit data not shown in the regular display, may be
seen at the push of a button.
TEMPERATURE: Most measurements (except ORP)
require temperature compensation. The Model 30
will automatically recognize either a Pt100 or
Pt1000 RTD, normally built into the sensor. When
this RTD is present, the Model 30 can be set up to
display the temperature in °C or °F as well as set
any one or more of the alarms and/or outputs to
respond to this sensor input. If two measurements
with temperature are present either can be chosen
for each alarm and output selected.
