12 – ALARM 1 MENU
ALARM 1 MENU is a sub menu of the MAIN MENU and serves for all settings related to alarms and protection.
Actually there are two sub menus, ALARM 1 MENU and ALARM 2 MENU but since both have same sub-menus
and settings and only difference is that ALARM 1 menu is associated to the SENSOR 1 and ALARM 2 MENU is
associated to the SENSOR 2, further description of ALARM 1 MENU can be directly applied to ALARM 2 MENU
and it won't be described separately.
ALARM 1 MENU has several sub menus which logically divides alarms into several groups according to TYPE of
the alarm and there is a SETTINGS menu for alarm sound settings and hardware IN/OUT configuration.
Before we get into individual alarm types, it is necessary to explain how alarms work and how they are handled.
ALARMS HANDLING and OPERATION
SMΩRF has extremely deep alarms processing and allows to configure alarm conditions and actions for various
requirements and situations. SMΩRF provides five (5) different
types of alarms simultaneously: SWR Alarm,
Low and High Power Alarm, High IMD Alarm for PSK and Arcing (hot switch detection) Alarm.
Each alarm type can be globally enabled or disabled. Disabled alarm type is disabled for all screens of the
sensor. We get to alarm types later.
Each alarm type can trip three different, user adjustable levels of importance . These levels are: WARNING ,
ALARM and FAULT . WARNING represents the lowest level of importance, ALARM middle and FAULT the
highest. Higher level alarm has priority and overrides lower level alarm. When some alarm type is globally
enabled, its importance levels can be individually enabled or disabled for each screen separately in SCREEN
MENU. This does not apply to PSK and Arcing Alarms, they have just one importance level and cannot be
controlled by the SCREEN MENU, only be globally enabled or disabled.
Every enabled alarm generates visual feedback on the front panel by ALARM light. This light goes green on first
WARNING level, red on ALARM level and flashing red on FAULT level. On some screens, where real estate
allows it, there is also alarm icon on the display, showing which type of the alarm got tripped.
Each importance level can be set for different
action . There are three available actions for each alarm level:
DISPLAY , SOUND and TX BREAK .
•
DISPLAY action enables alarm pop-up window to appear on display. Pop-up window shows alarm type,
importance level and real time value which caused the alarm. There are also two icons for clearing
tripped alarm: SNOOZE (SNZE) and RESET.
•
SOUND action, when enabled, generates audible alert for an operator. Sound and volume for all
importance levels can be set in the SETTINGS menu.
•
TX BREAK action breaks power generation by transceiver.
