ES601 Plus OPERATING MANUAL
8.5.17 Patient-Applied Parts (all standards except IEC61010)
This test is enabled by checking the Patient-Applied Parts box, unless the safety standard is one of
the "-BAT" standards, in which case this test is always enabled. In this test, ES601
Plus
measures the
current that flows out of the applied parts of the DUT through the human body load, when the
parts are either connected to protective earth, or they are connected to an isolated mains supply
(isolated AC line). This latter test is referred to as a "mains-on-applied-part" (MAP) test. Under the
IEC60601 standard, the MAP voltage equals 110% of the AC supply voltage to the DUT; for all
other standards the MAP voltage is equal to the AC supply voltage. For the "-BAT" standards,
patient-applied parts must be isolated from protective earth (Type BF or Type CF under IEC601-
BAT and AAMI-BAT; or Type F under VDE-BAT or IEC353-BAT).
8.5.18 Applied Part Groups (all standards except IEC61010)
An Applied Part Group consists of one to ten contiguous applied parts. Also, Groups encompass
the applied parts in order, starting from applied part 1 (AP1). For example, Group 1 may consist of
applied parts #1 to #3, Group 2 may consist of applied parts #4 to #5, and Group 3 may consist of
applied part #6. In all but the AAMI Standard, Group 1 is always enabled and has at least 1 applied
part.
The Applied Part editor is accessed by clicking on the Applied Parts tab. The Applied Parts tab will
be accessible only if Leakage Current is enabled and one of "Patient - Applied Parts" or "Auxilliary
(Interlead) Leakages" is selected. After clicking the Applied Parts tab, an Applied Part Group can be
enabled by either checking the Group checkbox, or by entering a non-zero number of applied parts
for that Group. The Applied Part Names and Status panel will display the applied parts that have
been enabled. A name can be given to the Applied Part Group by editing the Name textbox.
An applied part Group may be disabled after entering a non-zero number of applied parts for that
Group. The disabled Group will then separate the enabled Groups on the front panel connections
to the analyzer.
The type of protection class can be changed by selecting either the B, BF or CF radio button. In the
AAMI ES1 and AAMI-Battery Standards, Group 1 always has a protection class of "Isolated",
which corresponds to "Body-Floating"; and Group 2 always has a protection class of "Non-
Isolated", which corresponds to "Body".
Type B refers to "Body" or "Non-Isolated" protection class. That is, the applied parts are not
electrically isolated from protective earth. Type B parts have the least stringent safety requirements.
ES601
Plus
will measure patient leakage current while all the Type B applied parts in the applied part
Group are shorted to ground.
