36.8
When the control circuit specified in 36.5 is not limited as to
available short-circuit current by the construction of a
transformer, and the circuit includes either one or more
resistors, a fuse, a nonadjustable manual-reset protective
device, or a regulating network (see 36.12), the circuits in which
the current is limited, in accordance with 36.9, 36.10, or 36.11,
is not required to be investigated.
N/A
36.9
A fuse or circuit-protective device provided in the control circuit
used to limit the current in accordance with 36.8 shall be rated
or set at not more than the values specified in Table 36.1.
N/A
36.10
A fuse or circuit-protective device is able to be connected in the
primary of a transformer to limit the current, in accordance
with 36.8, when the protection is equivalent to that specified
in 36.9. This shall be determined by conducting the Overcurrent
Protection Calibration Test, Section 52.
N/A
36.11
One or more resistors, or a regulating network, used to limit the
current in accordance with 36.8 shall be such that the current
under any condition of load, including short circuit, does not
exceed the values indicated in 36.5(b).
N/A
36.12
When a regulating network is used to limit the voltage or
current, in accordance with 36.5 - 36.11, and the performance
is affected by malfunction, either short circuit or open circuit, of
any single component - excluding a resistor - the network shall
comply with the following:
N/A
a) The environmental tests specified in 36.14 are to be
performed; and
N/A
b) Critical components shall be derated in accordance with the
Electronic Reliability Design Handbook, Military Handbook
Number 338-1A.
N/A
36.13
In a circuit of the type described in 36.8, the secondary winding
of the transformer, the fuse or circuit protective device, or the
regulating network, and all wiring up to the point at which the
current and voltage are limited, shall be evaluated to the
applicable requirements in this standard.
N/A
36.14
When it is determined that environmental tests in accordance
with 36.12(a) are required, the control is to be subjected to the
following tests, in accordance with the method described in the
Standard for Tests for Safety-Related Controls Employing
Solid-State Devices, UL 991:
N/A
a) Transient Overvoltage Test;
N/A
b) Ramp Voltage Test;
N/A
c) Electromagnetic Susceptibility Tests;
N/A
d) Electrostatic Discharge Test;
N/A
e) Thermal Cycling Test;
N/A
f) Humidity Test for a unit intended for a general environment;
and
N/A
g) Effects of Shipping and Storage Test.
N/A
Before and after each test, the control is to be checked for
normal operation. See 36.15.
N/A
36.15
The following test parameters are to be used in the
investigation of the control covered by 36.14 for compliance
with the Standard for Tests for Safety-Related Controls
Employing Solid State Devices, UL 991:
N/A
a) Critical components are able to be electrically supervised;
N/A
