Table 6-1: Setting Mode of Operation (Advanced Parallel Mode)
4. Master and Slave Units Default Operation
a) When a unit is programmed to Slave mode, it enters the Remote mode with
Local Lockout. In this mode, the Front Panel controls are disabled to
prevent any accidental setting change (refer to Section 8.2.7 for details).
b) The Slave unit's parameters will automatically set the following:

Output Voltage to approximately 102% of rated Output Voltage

Programmed Current to zero

UVL to zero volts

OVP to its maximum value

AST ON

OUT ON

Foldback Protection OFF
c) The Master and Slave operating modes are stored in the power supply
EEPROM memory when the AC Input power is turned Off. The system will
return to the Master/Slave operating mode upon the re-application of AC
Input power.
5. Current Display Accuracy
In the Advanced Parallel mode, the Master unit calculates the total load current
by multiplying the Master Output Current by the number of Slave units. In this
method, the CURRENT display accuracy is 2% +/- 1 count. In cases where
higher accuracy is required, it is recommended to use the Basic Parallel
operation mode.
6. To Release Units from Slave Mode
Slave units can be release from their operating mode by using the following
procedure:
a) Depress the FINE button for 3 seconds. The Master/Slave configuration
will be displayed on the CURRENT display.
b) Select H1 mode using the CURRENT encoder.
c) Depress the FINE button again or wait 5 seconds.
d) Turn the AC input power Off to store the new setting(s).
e) After exiting from Slave operation the unit's parameters will be set to:
Operating Mode
Single supply (default)
Master supply with 1 Slave supply
Master supply with 2 Slave supplies
Master supply with 3 Slave supplies
