9.12 Current overload
The current controller uses the highest measured
current value for phases L1, L2, and L3. If this current
value exceeds the set value of the main fuse, the
temperature controller is overridden by the stage
regulator downshifting. In this mode, the temperature
controller is only permitted to downshift or retain the
present value.
If the current value + current margin is less than the
value of the main fuse, the temperature controller is
permitted to increase the stage output. The current
margin is set in the Settings menu.
The regulator utilises normal temperature control. The
output stage is not permitted to increase above the
output set point. When the external output set point
changes, the regulator follows the signal and shifts up
every 16 seconds.
9.13 Output control
9.14 Current limitation
If necessary, the output of the boiler can be limited
when, for example, the current drawn exceeds the
main fuses of the system. The connection of current
sensors to the system-specific current transformers’
0–5 A side must be done in accordance with the
boiler’s associated wiring diagram. The function is
activated in the
Define System menu. Here, the
current transformer's conversion can be specified
(primary and secondary side).
9.15 Current sensors
As depicted in the illustration, the current sensors
must be mounted to the current transformer's
cabling. For connection to the boiler, please refer to
the actual model's wiring diagram. Current sensors
are available from Osby Parca as boiler accessories.
These current sensors can
be ordered from Osby Parca.
