Chapter 6: Configuration Menu
Overview
This chapter describes how to view and change Digester Gas Monitor channel parameters
including alarm point settings and channel relay settings using the Configuration Menu.
The Configuration Menu is accessed using the ESCAPE and ENTER control switches.
The Configuration Menu includes a 5-minute timeout feature. If you do not press a control
switch for 5 minutes, the Digester Gas Monitor automatically returns to Standby Mode.
NOTE: If the Digester Gas Monitor returns to Standby Mode because of a timeout, it
enters a warm-up period just as it does when it is first turned on.
If you are installing a new Digester Gas Monitor, it has been set up at the factory.
Use the Configuration Menu only if you want to change one or more channel’s
parameter factory settings. If you want to change a channel’s detector type see
“Chapter 7: Input Setup Menu” on page 57.
Viewing and Changing Channel
Parameters
WARNING: The Digester Gas Monitor is not an active gas monitoring device while in the
Configuration Menu. When you enter the Configuration Menu, the 4-20 mA
output signal will “freeze” at 3.5 mA for each active channel, all relays and
alarm LEDs will remain in their current state at the time that you entered the
Configuration Menu, and the alarm buzzer and strobe will turn off if they were
activated until you exit the Configuration Menu. The 4 - 20 mA output signal will
not indicate current readings and the relays and alarm LEDs will not resume
operating normally until the Digester Gas Monitor is in normal operation again.
1. While in Standby Mode, simultaneously press and hold the ESCAPE and ENTER
buttons for approximately 5 seconds to enter the Configuration Menu. Release the
buttons when the
