Specification and
Inspection Certificate provided with the product
for configuration details. This section describes
the operation of pre-configured units, and
includes procedures for altering settings.

The Operator Panel allows you to communicate
with Gasmaster. Use it to monitor the status of
all attached field devices, determine system set-
tings and configuration of field devices. Figure

The User display provides continuous readings
for up to 4 field devices plus a display area for

Gasmaster 1 provides display for one field device
plus the message area.
Message display area
In normal, non-alarm condition, the message area
displays the channel numbers and detector types,
e.g. CH4 refers to methane detector, see follow-
ing example.
The # symbol represents the channel number (i.e.
#1 is channel 1).

In the event of an alarm, this message area will
display the channels in alarm and their location.
