4.1.2.14 Alarm setpoint lockout
If the Alarm Setpoint Lockout is enabled, the user may only view (not change) the Alarm-1 and Alarm-2
level settings. The Alarm Lockout setting is accessed from the Setup Main Menu by typing “6” on the RS-
232 terminal. To go back, use the <Esc> or “Q” key on the RS-232 terminal.
4.1.2.15 Gas calibration lockout
If the Gas Calibration Lockout is enabled, the user may not change, but only view the Gas Calibration
value. The Gas Calibration Lockout setting is accessed from the Setup Main Menu by typing “7” on the
RS-232 terminal. To go back, use the <Esc> or “Q” key on the RS-232 terminal.
4.1.2.15.1 User menu lockout
If the Front Menu Lockout is enabled the user may not manually initiate any User mode from the control
panel. The User Menu Lockout setting is accessed from the Control panel Locks menu by typing “8” on
the RS-232 terminal. To go back, use the <Esc> or “Q” key on the RS-232 terminal.
4.1.2.16 Assume low-end (reference) calibration
The Model 3100 analyzer uses the Assume Low-End Calibration value (Zero Calibration Range in the
setup menu) to recognize Reference Calibration gas (20.9 % oxygen) automatically, when applied to the
oxygen sensor during calibration. When calibration gas applied outside of the factory-set Assume Low-
End Calibration range of 18 to 24% oxygen, the analyzer assumes that it is Span gas. Refer to section
3.2.1 for a detailed calibration procedure.
WARNING: The Assume Low-End Calibration value is set to 18 to 24% oxygen at the factory, and it
should not be adjusted by the user. If the user changes the Assume Low-End Calibration range, the
Model 3100 will not operate properly.
4.1.2.16.1 Calibration mode auto return to RUN
This setting determines the minimum time that the Model 3100 allows after exiting from control panel or
service port user menus, before returning the unit to on-line status. The calibration mode auto return
setting is accessed from the Control panel Locks menu by typing ”T” on the RS-232 terminal. To go back,
use the <Esc> or “Q” key on the RS-232 terminal.
4.1.2.17 Line voltage – 208 Volt
The 208 Volt Line Voltage setting allows the user to set the AC supply voltage to the Remote Sensor
Module. Note that the software settings must match the AC switch setting on the RSM module (refer to
the equipment manual). The 208 Volt Line Voltage setting is accessed from the Control panel Locks
menu by typing ”L” on the RS-232 terminal. To go back, use the <Esc> or “Q” key on the RS-232
terminal.
4.1.3 Change factory settings via hardware jumpers
4.1.3.1 Analog voltage output
The Analog Voltage Output must be configured using the hardware settings. In addition, the software
settings must match the jumper settings. Software changes are made via the Control panel User Setup
menu (see section 4.1.1) or the Service Port RS-232 User Setup menu (see section 4.1.2.7).
