Local Operation
Important: The slave unit discussed here is not the same as the remote interface slave described in chapter 5.
Setting Over Voltage Protection (OVP)
The master unit’s OVP should be programmed to the desired OVP level. The OVP of the slave units should be programmed to a higher value than the master OVP. When the master unit shuts down, it will program the outputs of the slave units to zero volts. If a slave unit shuts down, only that unit would shut down and the remaining slave units would supply all the load current if possible.
Setting Foldback Protection
Foldback protection is only available on the master units as the slaves operate in constant current mode. They should never crossover into constant voltage mode. If foldback is triggered on the master unit, when its output shuts down, it will program the slave unit’s output to zero volts.
