changes to
CODE.C
, and the Upper display shows
1
. This means that all levels are
locked and cannot be changed.
8.7.3 Setting the Security Codes for Level C
If you first set
CODE.A
and
CODE.B
, the lower display will read
CODE.C
. If not, press
the
FUNC
key to move to
CODE.C
. The upper display shows
0,
which indicates no
security; a 1 means all parameters related to levels A, B, and C are always locked).
Press the
u
or
t
keys until the desired security code number (from 501 to 1000)
appears in the upper display. Press the
FUNC
key to lock in the value. The upper
display changes to
CodE
and the lower display changes to
UPR
.
Once the security codes are selected, they CANNOT be displayed. If the codes are
forgotten, new values must be entered using the above procedure. It is recommended
that a code be set for each security level. Note that unlocking the Level C code unlocks
Levels A, B, and C. To, relock a code, simply enter any incorrect number and all the
locked levels will relock. Unlocking the Level B code, unlocks Levels A and B. Unlocking
Level A unlocks only Level A. When the
SECUR
functions are accessed in Group 1, the
levels that are locked will be followed by a decimal point.
8.7 Configure Differential Pressure
The UPR800 has capability to indicate differential pressure. The primary and secondary
inputs can be either Strain Gage, 0-5Vdc, 0-10Vdc, 0-20mA or 4-20mA. Primary and
secondary input types need not be matched types. By default the UPR800-1-X-X with
secondary input option is shipped with setup to display temperature on the lower display.
To execute the differential display function Group 5 parameter SI.TYP needs to be set
from Temp (TC or RTD) to any Strain gage or V/mA setting and SI.FNC needs to be set
to diFF.P (Differential Pressure). Wire either a mV/V strain gauge transducer, Volt, or
Milliamp transmitter to terminals as show in Figures below.

For Primary Input (PT1)
For Secondary Input (PT2)
Note: If no internal Rcal is used, Cal1 and Cal2 may be omitted. For transducers with External cal resistors,
please refer to the manufacturers recommended wiring instructions.
