In general, the UPR700 Pressure/Process Indicator is a microprocessor-based instrument, with the
capability of monitoring one or two process variables simultaneously. The primary input is
configured to accept a 350
⍀
Strain Gage, but can be changed to accept high level voltage or
current. The primary input full-scale value can be as low as 10, and as high as 99,950 units. The
secondary input, if supplied, will accept a “J” type thermocouple, but can be changed to most
thermocouples or RTD’s, or to a high-level voltage or current. The secondary input full-scale value
can be as low as -1,000, and as high as 3,000 units.
The standard UPR700 has 2 SPDT dry contact closure alarms, with an optional third alarm. In
addition, it has one or two scalable analog retransmission outputs, or RS485 communications.
Alarm 1 is configured as a High Alarm at 40% of the full-scale transducer value, with 0.4 second
filtering, 1.0% hysteresis, Auto reset, failsafe mode, and it is linked to the primary input.
Alarm 2 is configured as a High Alarm at 60% of the full-scale value, with 0.4 second filtering, 1.0%
hysteresis, Auto reset, failsafe mode, and is also linked to the primary input,
Alarm 3, if supplied, is configured as a High Alarm at 80% of the full-scale value, with 0.4 second
filtering, 1.0% hysteresis, Auto reset, failsafe mode, and it is disabled (not linked to any input),
These terms will be described in the ALARMS section.

1. Remove the instrument from its case. To accomplish this, spread the two locking tabs located on
either side of the case. The instrument will move forward past the locked position. Grasp the
bezel and slide the instrument from the case.
2. Slide the case into the panel cutout. MAKE SURE TERMINAL 1 IS AT THE TOP! Attach the panel
mounting hardware at diagonally opposite sides of the top and bottom of the case, tightening
the threaded rod until the case is secure against the panel.
3. Carefully slide the instrument into the case until the locking tabs engage with an audible click.
4. Attach the primary and secondary devices, (if supplied), and wire according to the terminal
assignments as described in the Dynisco INSTALLATION AND OPERATION MANUAL FOR
THE UPR700 MICROPROCESSOR-BASED PRESSURE/PROCESS INDICATOR (part number
974090) included with the instrument.
