Starting Up the Digester Gas Monitor
Perform the following procedure to place the Digester Gas Monitor into normal operation.
NOTE: The following screens illustrate a four-channel Digester Gas Monitor. Depending
on what version of the Digester Gas Monitor you have, your screens may appear
slightly different.
1. Complete the mounting and wiring procedures described earlier in this chapter.
2. Verify that all wiring connections are correct and secure and that the Digester Gas
Monitor’s power switch is in the OFF position.
3. Plug in or turn on the incoming power source (AC or DC).
4. Turn on the power switch if AC power is used as primary power.
5. The following screen appears for a few seconds.
6. The Version Screen then appears. It shows the instrument’s hardware and firmware
versions for a few seconds. HW is the hardware version. Main is the main firmware
version. MB is the Modbus firmware version. The version numbers on the bottom line
are the firmware versions loaded for each channel.
To keep the version information screen on the display longer than a few seconds,
press and hold the ENTER button while it is being displayed. When you release the
ENTER button, the startup sequence will continue.
7. After the Version Screen has been displayed for a few seconds, WARMING UP
appears for each active channel. The warm-up time is counted down in seconds from
60 seconds for each active channel on the far right.
NOTE: To prevent unwanted alarms during warm up, the alarm circuits are not active
while the WARMING UP message is displayed.
