Manual 2100-597G - Bard I30A1DA Installation Instructions Manual

Menu Descriptions
RON Relay on setpoint
Sets the CO concentration which the optional
2
relay is energized.
Low limit: 0 PPM
Factory setting: 1000 PPM
High limit: 2000/5000 PPM (depending on model)
ROF Relay off setpoint
Sets the CO concentration which the optional
2
relay is de-energized. Setting value lower than
RON provides direct action for detecting high
concentrations of CO
RON provides indirect action for detecting low
concentrations of CO
LCD display will be lit to indicate when the relay
is energized.
Low limit: 0 PPM
Factory setting: 950 PPM
High limit: 2000/5000 PPM (depending on model)
DSP Display configuration
Determines the LCD display configuration during
normal operation. The LCD display can indicate
the CO concentration and the temperature,
2
the CO concentration only or the temperature
2
only. The factory default is to display both the
temperature and the CO
CT CO concentration and temperature
2
C CO concentration only
2
T Temperature only
UNI Units selection
Temperature and barometric pressure
measurements can be displayed in US
engineering units or SI engineering units. The
factory default is to display US engineering
units.
US units F for temperature and in Hg for
barometeric pressure
SI units C for temperature and hPa for
barometric pressure
COL CO low output range
2
Sets the CO concentration for the lowest output
2
(4 mA or 0 VDC).
Low limit: 0 PPM
Factory setting: 0 PPM
High limit: 2000/5000 PPM (depending on model)

COH CO high output range
2
Sets the CO concentration for the highest output
2
(20 mA, 5 VDC or 10 VDC). When COH is set
above COL, the transmitter is direct acting and
the output will increase with an increase in CO
level. When COH is below COL, the transmitter
is reverse acting and the output will increase
with a decrease in CO
Low limit: 0 PPM
Factory setting: 2000/5000 PPM
(depending on model)
High limit: 2000/5000 PPM
(depending on model)
TOL Temperature low output range
Sets the temperature for the lowest output
(4 mA or 0 VDC).
Low limit: 32.0°F/0.0°C
Factory setting: 32.0°F/0.0°C
High limit: 122.0°F/50.0°C
TOH Temperature high output range
Sets the temperature for the highest output
(20 mA, 5 VDC or 10 VDC). When TOH is set
above TOL, the transmitter is direct acting
and the output will increase with an increase
in temperature. When TOH is below TOL, the
transmitter is reverse acting and the output will
increase with a decrease intemperature.
Low limit: 32.0°F/0.0°C
Factory setting: 122.0°F/50.0°C
High limit: 122.0°F/50.0°C
BAR Barometric pressure
Sets the typical barometric pressure for the
location where the transmitter is mounted. The
factory setting is for standard pressure at sea
level. Adjusting the barometric pressure gives a
more accurate measurement, especially at higher
elevations.
Low limit: 20.0 in Hg/600 hPa
Factory setting: 29.9 in Hg/1013 hPa
High limit: 32.0 in Hg/1100 hPa
