2. Setting the units as Master or Slave
a) Depress and hold the FINE button for 3 seconds. The Master/Slave configuration will be
di
s
played
on the Current Display. Rotate the CURRENT encoder to obtain the desired mode. Refer to Table 5
-

for the CURRENT display and modes of operation.

4: Setting mode of operation
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.
d) Master unit does nto display actual total current of all the units
in parallel.
4. CURRENT display accuracy
In the advanced parallel mode, the Master unit
does not display actual total current of all units in parallel.
In
this method, the CURRENT display accuracy is 2% +/
-
1 count. In cases that higher accuracy is r
e
quire
d, it
is recommended to use the basic parallel o
p
eration 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.
e) After exiting from Slave operation the unit’s parameters will be set to:
*Programmed Voltage to
zero
