[ent] to Select 1=Weekend Day

[ent] to Select 1=SAT A to view

5=Late Work

The Late Work option authorises an Autoset Extension in advance of the prewarning period.

6=Weekend Work

The Weekend Work option unsets the system at the weekend. If the Weekend Day is programmed other than 0 = OFF (default), on the next occurrence of the programmed Weekend Day, the Timers adopt the times they have on the assigned Pattern day. For example, this allows a Sunday to use the Autoset and Lockout Timers of a Monday.

NOTE: Parameter 41 = Weekend Work must be enabled (default is Disabled) to allow the Weekend Day to be selected by the user.

On selecting the 1=Weekend Day option the programmed Weekend Day is displayed; the default is 0 = OFF. Use the A or B keys to select the required day or days and press the ent key to accept the program- ming and return to the previous menu level:

0

=

OFF

1

=

SAT

2

=

SUN

3

=

BOTH (Saturday and Sunday)

The selected Weekend Day remains active for one occurrence only. The Weekend Day returns to the default of OFF immediately follow- ing the assigned day. The Weekend Day must be allocated each time the function is required.

On selecting the 2=Pattern Day option the user is shown the pro- grammed timers that are effective when the Weekend Day option is selected. The timers of the selected Pattern Day (Mon to Fri) are adopted by the days selected for the weekend work.

NOTE:

The Pattern Day can only be allocated by
