EC-13/ EN 60601-2-49 Option
This option allows the Defib-5 to act as the
circuit described in EC-13, Figures 9 and 9A or
EN 60601-2-49, Figure 101. Please refer to
Figure 2-1 for a schematic of the circuit in EC-
13, Figures 9 and 9A, and Figure 1 for the
appropriate front panel connections needed to
conduct these tests with the Defib-5. Test
connections are the same for EN 60601-2-49,
Figure 101.
The connection information for the Defib-5 is
shown in green text on Figure 2.
Notes on testing with the EC-13
option
Testing with the EC-13 option requires
substantial changes to the circuitry in the Defib-
5, and these changes are accomplished using
jumpers on the front panel, and by using
different output jacks from the EN 60601
outputs. Some models may have jacks on the
rear panel instead of the front panel. The front-
panel jack representation is shown in Fig. 1 for
clarity.
The changes to the circuit are as follows, along
with the appropriate actions to perform on the
front panel:
1.
EC 13 SENSE Jack: This jack is necessary
to verify the value of the 100 ohm resistor.
(Refer to Figure 1-1 for the jack location on
the front panel, and to Figure 2-1 for the
schematic location.) The 100 ohm resistor
value is measured between the EC 13
SENSE jack and the RETURN jack on the
front panel.
2.
Inductance Jumper: For testing to EC-13, a
25uH inductance is required. To provide
this inductance, the provided front panel
jumper must be REMOVED.
3.
EC-13 S2: This switch is provided to
protect the Signal Generator from the output
pulse of the Defib-5 when CLOSED, and to
allow the required 5V p-p signal to be
injected when OPEN.
4.
10 HZ, 5V P-P INPUT: BNC provided on
front panel is for connection to the signal
generator required for the Defibrillator
Overload Test as shown in EC-13, Fig. 9A.
5.
400 OHM Jack: This is the output jack
from the Defib-5 used with EC-13 Testing.
It provides the correct pulse to the EUT, in
accordance with EC-13 Figures 9A and 9B.
Do not use the 50 OHM output jack, which
is provided for testing to EN 60601.
6.
RETURN Jack: This jack is used for the
return of the test voltage, named P2 in EC-
13.
7.
MEAS. POINT: This is the point which is
connected to the voltage divider network to
determine PASS/FAIL results of the test.
See Fig. 2 for more details.
8.
Y1 – Y2: These differential outputs are to
be connected to two different channels of an
oscilloscope, then the outputs are subtracted.
This resulting waveform is used to judge
acceptability of the EUT.
