Operating instructions

66
Example 3
The following illustration shows a total of 6 power controllers with symmetrical load distribution in a
three-phase network:
4 Thyro-P 2P power controllers
2 Thyro-P 3P power controllers
All ThyroP units in the following diagram are set up with an in phase grid connection.
The device labelled unit 1 operates in this configuration as a dASM master for all units, as units 5
and 6 are connected in phase with units 1 to 4.
dASM commissioning
To ensure optimal functionality of the dASM grid load optimization the following must be adhered
to when commissioning:
• Check Thyro-P for in phase grid connection
• Check wiring of patch cable
• Select operating mode TAKT (with same TAKT cycle period) for all Thyro-P devices
Parameterization of the master units:
o dASM NO. OF DEVICES
o dASM POWER THRESHOLD [W]
• Start up of the dASM group (=>switch-on)
dASM notification
The dASM grid load optimization generates the following notifications in the master unit should
errors arise:
dASM device number is incorrect:
check patch cable connections/parameter dASM device number
• dASM power limit has been exceeded: reduce set points of the assembly as appropriate
The notifications generated can be reported via:
• data logger,
• LED,
• Relay,
• LBA-2 (in preparation) or
• Thyro-Tool Family
ERRORS IN dASM COMMUNICATION
Should the dASM communication become interrupted (for example, an interruption between unit
6 and unit 7) during operation of the assembly e.g. as the result of a cable break or similar, then a
new master is automatically generated in the system beyond the point of interruption during opera-
tion – the dASM system continues to run and unit 1 now operates only as a master for units 1-6 and
displays that only 6 units are present in the dASM network. Notification: “dASM device number is
incorrect“.
