Operator Access Levels; Time Program Description - Honeywell Excel 50 User Manual

Password protection ensures that only authorized personnel have access to system
data to ensure reliable and trouble-free operation using the preset values.
The Operator access level 1 is not password-protected. This level enables only to
read such data as setpoints, switching time points, and operating hours.
The Operator access levels 2 and 3 are password-protected. Authorized personnel
can change the preset values at those levels. Operator access levels 2 and 3 have
different passwords.
Operator access level 1 - read only (default values)
Operator access level 2 - read and limited changes
Operator access level 3 - read and make unlimited changes - level-3 password

Time programs are used to assign setpoint values and control status conditions to
specific user addresses at specific times.
The time program can be adapted to suit the application. A time program comprises
the system time (which includes the current date, time and daylight savings time)
and various time-related programs, the daily time programs, the weekly time
program (created from daily time programs) and the annual time program. Time
program switching points can be changed via operator access levels 2 and 3.
System Time The system time includes the current date and time and the start and end date of the
daylight savings time. It regulates all analog and digital control strategies
implemented in the application software program.
Daily Time Program Switching point times with the desired value/status for the appropriate user
addresses are entered into the daily time program.
Example: The daily time program 'Workday' has several switching point times:
Workday
Weekly Time Program Daily time programs are assigned to each day of the week in the weekly time
program. The weekly time program is automatically repeated every week and
creates the normal annual time program.
Example 1: Monday to Friday inclusive require the same daily time program.
Saturday and Sunday require a different daily time program:
Monday
Tuesday
Wednesday
Thursday
Friday
Saturday
Sunday
