automatic calibrations, set the Auto Cal pa-
rameter to Yes.
f. The Output Tracks setting determines
whether the analog output tracks the oxy-
gen reading during a calibration. Setting
Output Tracks to No locks the analog output
value to the last measured oxygen reading
until the calibration is complete.
g. The Cal Interval parameter sets the time in
hours and days between automatic calibra-
tions. When Auto Cal is set to NO, this pa-
rameter is set to OFF.
h. The Next Cal parameter displays the time
until the next scheduled automatic calibra-
tion. If automatic calibration is not enabled,
this parameter displays Disabled.
i. The Gas Time parameter sets the amount
of time that calibration gas flows during an
automatic calibration before a reading is
taken. This value is not used for semiauto-
matic calibrations.
j. The Purge Time parameter sets the amount
of time after an automatic calibration before
the system is returned to normal operation.
This allows time for the calibration gases to
clear the lines and the system to return to
the process gas concentration. This value is
not used for semiautomatic calibrations.
k. The Res Alarm parameter displays the set-
point for the Res Hi alarm. Do not change
this parameter unless directed by a qualified
Rosemount Analytical Service Engineer.
l. Press the ESC key twice to return to the
Main menu.
3-4 SETTING THE O
2
ALARM SETPOINTS
The IFT has a high and low O
2
alarm. To
change the alarm setpoints, press the SETUP
key on the GUI keypad and select the O
2
Alarms sub-menu.
The Hi Alarm and Lo Alarm values are the set-
tings for the high and low oxygen concentration
alarms, respectively. The Alarm DB parameter
allows the setting of an alarm dead band. When
a dead band is set, the O
2
value must change
by the dead band value before the alarm will re-
set. For example, if the Hi Alarm is set to 8.00%
and the dead band is set to 0.25%, the O
2
con-
centration must drop to below 7.75% before the
O
2
alarm will clear. This prevents the alarms
from continually activating and clearing when
the oxygen value is near the alarm setpoint.
3-5 CONFIGURING EFFICIENCY
CALCULATIONS
To enable efficiency calculations and set the ef-
ficiency constants, press the SETUP key on
GUI keypad, and select the Efficiency Calc sub-
menu. The Enable Calc selection turns effi-
ciency calculation on and off. Enter the K1, K2,
and L3 constant values in the appropriate fields.
Efficiency constant values are listed in Table 5-6
for oil and gas for the US and Europe.
3-6 CONFIGURING THE RELAY OUTPUTS
The IFT has two relays that can be individually
configured. Each relay can be triggered by three
separate events selected from a list of eight
events. Use the following procedure to configure
the relay outputs.
a. Press the SETUP key on the GUI keypad.
Select the Relay Outputs sub-menu.
b. Select K1 Setup or K2 Setup to configure
relay one or relay two, respectively.
c. Set Event 1, Event 2, and Event 3 to the
desired triggering event. The relay will be
energized when any of the three events oc-
curs. If you do not want a relay to trigger on
three events, set the desired trigger or trig-
gers and set the remaining events to Off.
Note that the TG Low event will only func-
tion if the system includes an MPS 3000
Multiprobe Test Gas Sequencer.
d. Press the ESC key and select the other re-
lay. Configure the relay as described above.
e. Press the ESC key three times to return to
the Main menu.
