7.0 START-UP PROCEDURE
In general, 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 configured to accept a 350
N 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 UPR800 has 2 SPDT dry contact closure alarms, with an optional third
alarm. In addition, it has one or two scalable analog retransmission outputs, or RS-485
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.
7.1 Getting Ready:
1. 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.
2. Attach the primary and secondary devices, (if supplied) and wire according to the
terminal assignments.
7.2 Configuring the UPR800:
Apply power to the cabinet. The upper display will show a reading near zero, and the
lower display will show the current temperature or PEAK if the unit does not have
secondary input. It may display OPEN if there is no transducer connected, or if the
transducer is amplified.
