Menu system overview Crowcon Gasmaster
24
Over the next few pages you will find a detailed
description of the menu system. Use figure 3.4 as
an overall guide to locate menu items.
Gasmaster has five standard menus: Faults,
Warnings, View, Actions and Supervisor. Only the
Supervisor menu allows you to configure Gasmaster.
This section contains tables that list the menu
items for each menu and the available values.
See "Using the Control Panel in Supervisor Mode"
on page 21 for instructions on how to alter set-
tings.
Note: The display only shows two lines of infor-
mation at a time. Use the Up
and Down
buttons to see additional menu items or values.
Use Continue
to select choices and Back to
exit menu.

The fault codes are numbered to relate to a particular channel where appropriate (e.g. fault code 19 means there is a fault
on Channel 4 Level 2 alarm relay).
