DYNISCO UPR800 Series Instruction Manual
Page | 7
1.0 INTRODUCTION
The UPR800 Pressure/Process Indicator is a microprocessor-based instrument, with the
capability of monitoring one or two process variables simultaneously. The primary input is
user configurable to be 350
K
Strain Gage, high-level voltage or high level current. If the
second input option is chosen, it is configurable by the user as any of four thermocouples,
PT-100 RTD, high-level voltage or high level current. They are compatible with many
process transmitters and can be scaled by the user to give an appropriate range in
engineering units. The UPR800, in its dual input version, can provide simultaneous
readout of common process variable pairs such as Pressure and Temperature,
Temperature and Humidity, etc., when used with the appropriate sensor / transmitter
combinations. Pressure value input and retransmission output groups are selected
though the keypad. Thus the need to make numerous selections within the instrument is
minimized. The UPR800 is provided with two alarms and an analog retransmission
output any of which can be assigned to the primary or secondary input. A second analog
retransmission output is available as an option, as is a 24Vdc power supply for two and
four wire process transmitters. A third alarm is also available as an option.
Five groups of configuration parameters are available from the keyboard, and are
protected by three levels of user definable software locks. The displays can be single-line
(primary input only; lower display blanked), dual line with primary input in the upper
display and high or low peak in the lower display, or dual display of primary input in the -
upper display and secondary input in the lower display. In the last mode, the lower display
can alternate between the secondary input and the primary input peak value via
keystroke. In addition, a red LED bar graph presents an analog representation of the
primary input, as well as indication of the alarm set points.
References to Profibus features and instructions should be ignored. Profibus is being
considered for a future line expansion and has been accommodated in the current design.
WARNING NOTE:
The user should be aware that if this equipment is used in a
manner not consistent with the specifications and instructions in this manual, the
protection provided by the equipment might be impaired.
