Additional fields can be edited by pressing the ENTER key until the desired field is selected. When the
last field is selected, pressing the ENTER key switches the display out of "edit" mode and returns the
arrow keys to "scroll" mode.
Alarms
When an alarm occurs, the alarm type, limit value (if any), date, and time are stored in the active alarm
buffer corresponding to that alarm (viewed on the Alarm Active screens) and also in the alarm history
buffer (viewed on the Alarm Log screens). The active alarm buffers hold a record of the last occurrence
of each alarm and whether or not it has been cleared. The alarm can be cleared by pressing the Edit key.
A separate buffer is available for each alarm (High Cond Pressure, Evaporator Freeze Protect, etc.). The
alarm history buffer holds a chronological account of the last 25 alarms of any type.
Security
Two four-digit passwords provide OPERATOR and MANAGER levels of access to changeable
parameters. Either password can be entered using the ENTER PASSWORD screen which can be
accessed either through the SET OTHER menu or by simply pressing the ENTER key while on one of the
SET screens. The password can then be entered by pressing the ENTER key, scrolling to the correct
value with the UP and DOWN arrow keys, and pressing ENTER again. Once the correct password has
been entered, the previously selected screen will reappear. Once a password has been entered, it will
remain valid for 15 minutes after the last key-press.
