Trip and Alarm
Up to fifteen trip and alarm messages can be displayed
in a scrollable-list format. Trips must be individually
selected and reset using the RESET key. All trips are
simultaneously reset by a digital-input reset or with a
communications-network command. Alarms are non-
latching and are displayed only for the time that the alarm
condition exists.
RESET is a "hot key" to the
Trip and Alarm
display,
except during set-point entry. In the
Trip and Alarm
display, pressing ESC or the left arrow key causes a
return to the display shown when RESET was pressed.

The default password is 1111. When the digital
input is programmed for Program Enable, set-point access
via the menu system is controlled by the digital input state
and not by the password. Set Points can always be
changed using communications and the password.
When password access is active, all set points are
locked from changes until the four-character password is
entered. If set-point access is locked, the user is prompted
to enter the password. Once entered, set-point access is
allowed and remains enabled until a key has not been
pressed for the time defined by the
Password Timeout
set
point.
Set points are selected either by entering alphanumeric
characters or by choosing from a list.
