Notes:
1. During system operation, the UPC must be metering system output for Current Protect to
operate. Current Protect (as with voltage and current metering) is disabled during program
edit or UPC Setup mode for firmware revisions 5.2.2 or lower.
2. When the System Output is disabled due to Current Protect, the UPC will display, "ERROR
– CURRENT PROTECTION TRIGGERED". Either the CLEAR or DISPLAY button must be
depressed to clear the fault before the UPC32 OUTPUT ENABLE switch will operate.
3. It is recommended the Current Limit (Ilim) be set to a value greater than Current Protect
(IprA). Setting current limit at or below current protect value will prevent Current Protect
from disabling the power source output.
4. During "Transient Operation" UPC Metering timing is modified. Subsequently, Current
Protection operation may be affected.
