Note: when setting current, instantaneous current value Ii should bigger than short delay current setting value Isd, should bigger than long delay setting value IR, that is IiIsd IR. If long delay, short delay and instantaneous setting values are overlapping,priority should be:
instantaneous release→short time delay release → long time delay.
