5 Configuration
Type of soft start With phase angle
control
The phase angle is steadily reduced starting from 180° until
a full wave has passed through.
The soft start has been completed and the power controller
switches to burst-firing mode.
Note: If the output level drops to 0% for longer than 8 sec-
onds, the power controller restarts with a soft start once the
output level increases again.
If the current limitation is activated during the soft start phase,
reaching the full wave depends on the current limitation.
With pulse groups This setting is present in the operating mode "burst-firing
mode with fixed cycle time" as well as "with fastest cycle time
possible".
During the soft start time the ON/OFF ratio is
increased from 0 to max. 100%.
Soft start duration 1 ... 65535s This is the duration of the soft start.
Current limiting
no No current limiting
yes Current limiting is realized by means of phase angle control.
During this, the load current is monitored for the set current
limit value.
Only those phase angles are permitted that do not exceed the
current limit value.
It is also possible to activate an external current limit
via a binary input.
Chapter 5.1.6 „Binary inputs“
current limit 10% ... max. load
current +10% of the
device type
Varies according to the type of device.
For 20A power controllers it is possible to set 2 ... 22A.
v Chapter 1.3 „Order specifications“
Note:
Ensure that the value exceeds 10% of the max. control-
ler current, i.e. >2 A for type 70.9062/8-01-020...
