  • Page 51 (ungrounded) load path using the I(t)/I(r) switches. I(r) current is a component of total load current, I(t). I(t) (total load current) refers to all of the load current which is returned to the 610D except those load currents which are returned to the I(s) terminal. Total load current, I(t), is monitored by the 610D and provides a means for close regulation and monitoring of the total load current using the I(t) and I(r) switches.
