The fault/error detection time is the period between the execution (after the
fault has occurred), of the relevant software segment, either for function or for
checking purposes and the completion of the declared control response.

time for the:
• first fault shall be according to H.27.1.3.102.1 and H.27.1.3.104.1
• second fault shall be according to H.27.1.3.102.2 and H.27.1.3.104.2

H.26.5 Test of the influence of voltage dips and short voltage interruptions in the
power supply network
Replace the existing title with the following new title:
H.26.5 Voltage dips and voltage interruptions in the power supply network
H.26.5.2
Delete the existing subclause (introduced by Amendment 1) and replace with following new
subclause:
H.26.5.2 Test values
Replacement:
The system shall tolerate voltage dips, short interruptions and voltage variations in the
electricity supply so that, when tested in accordance with H.26.5.3,
a) for the values of Table H.101 criteria a): it shall continue to function in accordance with
the requirements of this standard. It shall neither proceed to safety shutdown or lock-out,
nor shall it reset from lock-out;
b) for the values of Table H.101 criteria b): either it shall perform as in a) or it may proceed
to safety shutdown followed by a system restart, or if in volatile lock-out it may proceed to
a system restart.
NOTE Non-volatile lock-out excludes the use of system restart.
When the power supply is restored, the system restart shall comply with the requirements for
a start-up sequence.
Requirement b) can be ignored, provided that the power failure is less than 60 s and occurs
within 60 s after call for heat. On restoration of the power, the programme may be continued
from the point at which it was interrupted.
A shortened start-up sequence, for example, a start-up sequence without pre-purge or waiting
time, is allowed, provided that the power failure occurs within 60 s after the end of the start-up
sequence and is shorter than 60 s.
