NOTE
Constant Power Limit minimum limit setting is dependent on the number of units connected in
parallel. Single unit minimum value is 1W. Connecting additional units in parallel results in 1W
multiplied by n, while n is the number of units connected in parallel (including the master unit).
6.9.5 Slave units operation in Advanced Parallel connection
Slave units are automatically configured as slaves, according to advanced parallel bus paralleling
cable connection (G/P). Slave units show on the display the output state of the system “OUT ON”
or “OUT OFF” or faults in case a fault has occurred. Each slave unit displays only its own faults.
Slave units allow only query communication commands.
6.9.6 Advanced Parallel fault system
Advanced parallel fault system combines the faults of the master and slave units. The master unit
shows on the display and communications both its own faults and the slave units’ faults. Each
slave unit shows on the display its own faults only. Slave units show OUT OFF in case of a fault in
any of the other units. In case of a fault in any of the slave units, the system acts as if the fault has
occurred in the master unit.
6.9.7 Advanced Parallel system identification (*idn?)
To identify a system connected in parallel, master unit updates its identification name. Standard
unit identification string format is: TDK-LAMBDA,Gx-y,S/N,G:r.
•
x – rated voltage, y – rated current, S/N – serial number, r – firmware revision.
Parallel system identification string format: TDK-LAMBDA,GSx-z,S/N,G:r.
•
z – total advanced parallel system current.
The “S” letter, following the “G” letter, identifies advanced parallel system.
The total current of the system is updated, identifying the total current. The serial number of the
master unit is preserved.
NOTE
In case of a Blank Panel Option Power Supply, the additional paralleling system ‘S’ letter is added
following the ‘B’ letter, i.e. TDK-LAMBDA,GBSx-z,S/N,G:r.
