NOTE
With local sensing it is important to minimize the wire length and resistance. Also the positive and
negative wire resistance should be as close as possible to each other to achieve current balance
between power supplies
5.15.2.2 Setting the Units as Master or Slave
1. Depress and hold the FINE button for 3 seconds. The Master/Slave configuration will be displayed on the
CURRENT meter. Rotate the CURRENT encoder to obtain the desired operating mode. Refer to Table 5-4
for the CURRENT meter display and operating modes.
2. When the desired configuration is obtained, depress and release the FINE button or wait approximately 5
seconds.
CURRENT Display Parallel Operating Mode
H1 Single power supply (default)
H2 Master supply with One (1) Slave supply
H3
Master supply with Two (2) Slave supplies
H4
Master supply with Three (3) Slave supplies
S Slave supply

5.15.2.3 Master and Slave Units Default Operation
7. 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 7.2.7 for details).
8. The Slave units parameters will automatically set the following:

Output voltage PREV iew set to approximately 102% of rated Output voltage.

Output current PREV iew set to zero amperes.

UVL set to zero volts

OVP to its maximum value

AST ON

OUT ON

FOLD back protection OFF
The Master and Slave modes are stored in the individual power supply EEPROM memory when the AC Input
power is turned OFF . The system will return to the Master/Slave operating mode upon re-application of AC
Input power.
5.15.2.4 CURRENT Display Accuracy
In the Advanced parallel mode, the total current is programmed and reported by the Master unit. In this mode,
the Master unit CURRENT meter accuracy is 2% +/- 1 count. In cases where higher accuracy is required, it is
recommended to use the Basic parallel operating mode.
5.15.2.5 To Release Units from Slave Mode
Slave units can be released from Slave mode operation using the following procedure:
1. Depress the FINE button for 3 seconds. The Master/Slave configuration will be displayed on the CURRENT
meter.
2. Select H1 mode using the CURRENT encoder.
3. Depress the FINE button again or wait 5 seconds.
4. Turn the AC Input power OFF to store the new parallel operating mode setting.
5. After exiting from Slave mode operation the power supply operating parameters will be set to:

Programmed voltage to zero

Programmed current to zero

UVL set to zero volts

OVP set to its maximum value

AST OFF

OUT OFF

FOLD back protection OFF

