Setting Operator Input Parameters
Before adjusting any parameters, ensure the system is stopped. The Home Screen will display
STOPPED
or
RUNNING
in the upper right section of the screen. The ability to adjust input
parameters is disabled when the system is running. To stop or start the system, press the Right
Arrow Key on the Home Screen.
1 - Setting the System Configuration Parameters
To begin initializing a new system, the base System Configuration settings must be
set. In the System Configuration menu, the user has the option of selecting the system
units, if the system will resume automatically in the instance of a loss of power, and
selecting the system redundancy options.
To set the System Configuration Parameters
1.1. From the home screen, press the Select
Key to open the Main Menu.
1.2. Using the navigation arrows, navigate to
the System Configuration Menu and
press the Select Key.
1.3. Within this menu, navigate to the
desired Units and press the select key to
set the units. The parameter selected
will be identified by the filled circle next
to the parameter.
1.4. In the instance of a power loss while the
system is running, the system can be set
to resume automatically when power is
restored. To allow the system to resume
on power loss, use the navigation
arrows to navigate to the
“Resume on
power loss
” setting and press the select
key. If selected, the selection box will be
filled next to Enabled. If this parameter is enabled and the NJEX ZEO system loses
power while stopped, the system will resume in the stopped mode.
1.5. If the NJEX ZEO unit is part of a redundant system, navigate to System Redundancy
options and select if the current unit is the Primary or Backup system. The set selection
will be identified with a filled circle next to the selected option.
2 - Setting the Odorization Parameters
The N-400 controller can operate in two modes: Proportional-To-Flow or Proportional-
To-Time. Proportional-To-Flow reads an input signal provided by the customer to
determine the flow rate of the pipeline media and adjusts the amount of odorant injected
at a rate to maintain the target injection rate. Proportional-To-Time mode injects odorant by
setting a target mass per unit time value to maintain. Use the Odorization Parameters to set the
target Injection Rate and odorant parameters.
