Failure dependent change-over
Due to
a failure of
unit 04 unit 05 is
switched on.
Time dependent change-over
(normal sequencing)
e. g. with 2 standby units:
1. cycle unit 07, 11 standby
2. cycle unit 08, 14 standby
3. cycle unit 11, 01 standby
etc.

Cycle 2
The zone control comprises three specific functions:
1. Sequencing,
2. CW Standby Management,
3. Zone for DFC control
6.2.1 Sequencing
The sequencing provides a time dependent unit changeover.
By the use of standby units, a high operating reliability the
same as an even unit exploitation is achieved.
By setting the cycle time (parameter in the first line of menu
Z1) you adjust the lapse of time, after which a changeover
is done periodically. This means that the standby status is
changed over the units one by one. With the setting 0 (hrs) no
sequencing is made.
Setting the cycletime causes the sequencing start.
