SECTION 7 -
TECHNICIANS ONLY
MENUS
7.1 Introduction
WARNING ! Users of these menus must have a detailed understanding of their
functions. Monitoring of target gases, processing of alarms, 4-20mA output values,
Modbus RS-485 and wireless communications should not be relied upon while editing
these menus! Back-up the current configuration prior to altering any Technical menus
in case Restore is required later (see section 5.3).
The
TECHNICIAN ONLY menu group contains items that are factory configured
depending upon the type sensor and input connected to the OLCT 200. They should
not be tampered with after installation. If configured incorrectly, some items will
prevent monitoring of target gases.
The Set Sensor Voltage menu for setting the
catalytic bead sensor excitation voltage could destroy the sensor. Access requires a
special key sequence of four consecutive UP keystrokes to prevent accidental
modification of critical items.
