2. Setting the units as Master or Slave
a) Depress and hold the FINE button for 3 seconds. The Master/Slave configuration will be
displayed on the Current Display. Rotate the CURRENT encoder to obtain the desired mode.
Refer to Table 5-4 for the CURRENT display and modes of operation.
CURRENT Display
b) When the desired configuration is obtained, depress and release the FINE button or wait
approx. 5 seconds.
3. 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 accidental setting change (refer to Sec.
7.2.7 for details).
b) The Slave units parameters will automatically set the following:
*Output voltage to approximate. 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 modes are stored in the power supply EEPROM when the AC power is
Turned off. The system will return to the Master/Slave mode upon re-application of AC power.
4. CURRENT display accuracy
In the advanced parallel mode, the total current is programmed and reported by the Master. In
this method, the CURRENT display accuracy is 2%+/- 1 count. In cases that higher accuracy is
required, it is recommended to use the basic parallel operation mode.
5. To release units from Slave mode
Slave units can be released using the following procedure:
a) Depress 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 FINE button again or wait 5 seconds.
d) Turn the AC power Off to store the new setting.
