F.5.2 Sampler and Odorizer Configuration
See section F.5.2.1 for Sampler Configuration or F.5.2.2 for Odorizer Configuration.
F.5.2.1 Sampler Configuration
The user may enable or disable the Sampler by using the Enable/Disable button. If
enabled, the Sampler will operate at a frequency set by the Pulse Frequency setpoint (in
cubic feet). Users must select which Digital Output (DO) Point will be used. A running
count of samples taken will be displayed. Users may reset this count by pressing the Reset
Count button.
F.5.2.2 Odorizer Configuration
Users may enable or disable the Odorizer by using the Enable/Disable button. The user
also selects the Output Mode, i.e., Analog Output or Digital Output. If the Analog Output
Mode is selected, Analog Point ID 1 is assigned. If the Digital Output Mode is selected, the
Digital Output Point to be used is selected via the DO Point ID field.
When the Analog Output Mode is selected, the user must set the Scale Factor. The Scale
Factor is a ratio of the amount of odorant to be injected per cubic foot of gas. Users must
know the maximum output of the Odorizer and calculate the ratio accordingly.
