3.8.5 MASTER/SLAVE CONTROLS AND INDICATORS
Controls and indicators function as described for a single unit, however controls are only active
on the Master Load. Indicators on the Master Load are for Master/Slave configuration. Indica-
tors on the Slave indicate individual Slave Load current and power and Slave status (VOLTS
display reads SLAU). Slave LOAD switch indicators show engaged (amber) or disengaged
(green) status of each slave. Fault indications are displayed on each slave as well as the mas-
ter.
3.8.6 MASTER/SLAVE OPERATING NOTES/CAUTIONS/WARNINGS
Be sure to read and follow the operating instructions described for a single unit and observe all
Cautions and Warnings. A Master/Slave Load configuration is capable of extremely high power
and extremely high currents, thus suitable precautions should be taken when using the Load
• Use optimal damping (see PAR. 3.11) for setup instructions to optimize damping set-
tings, otherwise use factory default settings.
• Interconnect UUT and Load with cabling designed to minimize inductance. Remember
that rapidly-changing high-currents combined with inductance produces high-voltage
spikes (spikes that can easily damage equipment including the EL Load).
• To minimize spiking and current surges when using computer-controlled remote opera-
tion, the best sequence is:
1. Select Mode (e.g. MODE CURR).
2. Select very low value set point (e.g. CURR 0.2).
3. Engage Load (INPUT ON).
4. Slew Load to desired operating set point (e.g. CURR 105).
