5. SINGLE TEMPERATURE ALARMS
5.1 SYSTEM STATUS
The words “SYSTEM OK” will remain on the display unless an alarm, fault or enter program condition
occurs.
5.2 TEMPERATURE ALARMS
In the event any temperature attains an alarm set point, the common alarm relay (TB1) will trip as indi-
cated in the configuration menu. The beeper will turn on, and the display will brighten from its low inten-
sity to bright mode to identify the alarm parameters. The → NXT ALRM line will appear when there are
other active alarms to view. Navigate to menus to view and reset any alarms.
6. MULTIPLE TEMPERATURE ALARMS
In the event that multiple alarms occur, the first set point to sustain its threshold will be displayed.
Alarms that are received are placed in chronological order. The display automatically jumps to the next
incoming alarm if the acknowledgment is left unattended. The alarm-viewing structure of the display is
set up as a continuous spreadsheet so the administrator can CURSOR ► to a specific RTD number in
alarm and then CURSOR ▼ to the details. At any time cursor left Ctrl + CURSOR ► or right to jump to
the next column of another RTD. If the cursor is not in the top alarm menu and then shifted ◄► to the
next alarm, the cursor will jump to the top menu. The ALARM indicator flashes when the alarm is active
and goes solid when the alarm clears. When the alarm clears, reset it by selecting the ACK button on
the face plate.
