5.4.4 AS-i earth-fault detector

Replace the existing first and second paragraphs by the following two new paragraphs:

In accordance with IEC 60204-1, insulation faults on any control circuit shall not cause

unintentional starting, potentially hazardous motions or prevent stopping of the machine. To

fulfil this requirement, IEC 60204-1 indicates that control circuits that are not connected to the

protective bonding circuit shall be provided with an insulation monitoring device that either

interrupts the circuit automatically after detecting an earth fault or indicates an earth fault to

initiate a signalling at the machine.
---------------------- Page: 5 ----------------------
– 4 – IEC 62026-2:2008/AMD1:2019
 IEC 2019

If an AS-i network is used to control potentially dangerous movements of a machine and

IEC 60204-1 applies, an insulation monitoring device shall be installed. If the AS-i network is

composed of separate parts that are isolated from each other, an insulation monitoring device

shall be used for each isolated part of the network.
Table 15 – Connection and wiring identification

In existing footnote a, replace "IEC 60947-5-2" with "IEC 60947-5-2:2007/AMD1:2012".

8.3.2 AS-i earth fault detector
Replace the existing third paragraph by the following new paragraph:

The manufacturer shall declare the impedance range that can be detected by the earth fault

detector between ASI+ and ground and ASI- and ground. It shall be compatible with the

requirements for the detection of an insulation fault, in accordance with IEC 60204-1.

8.6.2 Immunity

Replace existing first dashed item of second paragraph by the following new dashed item:

– A. Normal performance within the specification limits and statistical maximum of one

disturbed master request or slave response per 30 transactions.
8.6.2.3 Conducted radio frequency disturbances

Replace existing text of this subclause (including the note) by the following new text:

This test shall be conducted with 3 V, in accordance with IEC 61000-4-6, and performance

criterion A shall apply.

NOTE The operating environment of these devices using an AS-i power supply with a decoupling network is

considered to be well protected against conducted radio frequency disturbances; therefore, testing with 3 V is

sufficient.
9.1.2 Type tests
Insert the following new paragraph after the existing dashed items list:
EMC tests of the AS-i network shall be conducted in accordance with 9.5.9.
9.5.4.3.2 Test procedure with current probe and oscilloscope (Figure 86b)

Replace the existing first sentence of the second paragraph with the following new text:

Switch S1 allows to provide the AS-i slave either with the signal from the master (to switch the

slave in the desired state) or with the a.c. sinus signal to determine the impedance.

9.5.9.1 Test conditions
Replace the existing first paragraph by the following new paragraph:

Unless otherwise stated, the tests shall be carried out on all AS-i-devices addressed in this

document at an ambient air temperature of 23 °C ±5 °C.
Change the existing reference in the 4th paragraph under b) to read:
