Paging down, we reach the shutdown page(s):
There are two schedules per page. Each schedule has a field for time on, time off,
days (of the week) and holidays. AM and PM are entered by selecting the first
character, using the +/- key to toggle the arrow keys to edit mode, then using the up
or down arrow to change the character to A or P as needed. The same means is used
to select the days of the week (once the cursor is placed in the space to the right of
the question) and holidays.
Holidays are given dates when Store Info is configured.
Evaporator alarms are configured on the last page for each evaporator. The right
illustration shows the screen when it is opened for the first time. The right illustration
shows the screen with all of its fields revealed. Additional information will be found in
section (Chapter 4-5) on alarms.
