5.1.1 PROG Switch
From the Main Display, the PROG switch enters into the Main Menu. Once inside the Main Menu, the
PROG switch acts as an “Escape” switch that moves backwards in the menu flow chart.
NOTE: While in Main Menu mode there are no updates to gas readings and hence no alarms
will take place.
5.1.2 “u” Up Arrow Switch
This switch moves the user up the Main Menu flow chart. It is also used to change selected entries
within menu selections in the upward direction.
5.1.3 “v” Down Arrow Switch
This switch moves the user down the Main Menu flow chart. It is also used to change selected entries
within menu selections in the downward direction.
5.1.4 ENTER and RESET/ACK Switch
This switch has multi-purpose uses. The ENTER function is used to accept selections within all menu
screens. The switch is also used to execute the Reset and Acknowledge functions. The Reset function
releases all latched relays if they have cleared the alarm/fault condition. The Acknowledge function
will disengage any silenceable relays that are in a currently active state. This is typically used to
silence alarms once the end-user has assessed the alarm condition. The RESET/ACKNOWLEDGE
function of the switch is only applicable from the Main Display and not while in Main Menu mode.
