Interface
The interface of the MAXTime comprises of a 4 line, 80 character
backlit Liquid Crystal Display (LCD) with Directional Cursor Keys,
Escape (#) and Enter keys. A menu system with on-screen user
instructions ensures ease-of-use.
The Default screen of the display shows the current time and status
of all relay channels. Pressing Enter on the keypad will take the user
to the menu system where schedule and configuration changes can
be made. The display always returns to the default screen if no keys
are pressed within two minutes.
The Schedule Menu allows the user to Add, Edit or Delete Weekly
and Yearly Schedules. Weekly Schedules require a Start and Stop
time in Hours, Minutes and Day of Week. Yearly Schedules require a
Date, Month and Year. The Yearly schedule will override all weekly
schedules from 0:00 of the Start Date to 24:00 of the Stop Date. i.e. A
Weekly Schedule for Monday 9:00 to Monday 17:00 on Relay Channel
1 will activate that relay every Monday between 9:00 and 17:00. If
however, a yearly exception schedule set to Start on 2nd September
2002 and Stop on the Same day, will override the Weekly Schedule to
o, since 2nd September 2002 is a Monday.
In addition to the Individual Yearly Schedules for each channel,
Schedules entered into the Master Yearly Schedule will override all
weekly schedules on all channels. This is a convenient way to add
holiday periods to all channels instantly.
