Installation of the power units for dASM operation
Amongst other things the following points are important for successful installation of dASM grid
load optimization
• Power/grid connection of all power controllers to be executed in phase
(see the diagrams of the following examples 1, 2, 3).
• dASM control cable connection (RJ45 patch cable) running from dASM master to the final Thyro-P
unit (see the diagrams of the following examples 1, 2, 3)
Installations examples
Example 1
This diagram shows 3 one phase Thyro-P
power controllers with in phase grid connec-
tion, connected to 2 phases of a three-phase
network or a single-phase network, along
with dASM wiring. The dASM grid load opti-
mization is operating on the example with all
connected and switched on Thyro-P units 1-3.
dASM group of unit 1 (M): 3 x Thyro-P
The device labelled unit 1 is operating in this
configuration as the dASM master of dASM
group 1. In total the dASM group can consist
of up to 32 Thyro-P devices. Additional
dASM groups of up to 32 Thyro-P devices operating independently of one another group can be
connected to the same grid so the number of Thyro-P devices which can be operated with dASM
grid load optimization can, in principle, be as large as desired.
Alongside the dASM control cable connection (RJ45 patch cable), which is required for all units, the
power/grid connection, in each case in phase, is a prerequisite for the formation of a dASM group.
Example 1a
This diagram shows 3 single-phase Thyro-P
power controllers with a grid connection
which is not in phase, connected to 2 pha-
ses of an three-phase network, or a single-
phase network, also with dASM wiring.
Due to the connection of unit 3 not being
in phase with regards to the preceding
unit 2, unit 3 autonomously forms a new
master (however operates independently
from units 1 and 2). This is why the grid load
optimization in this example only operates
with units 1 and 2, which means that, as a
result of the connection not being in phase,
the switching here, in comparison with the
switching in example 1, does not lead to
optimal grid load optimization.
dASM group from unit 1 (M): 2 x Thyro-P
dASM group from unit 3 (M): 1 x Thyro-P
