7. An appropriate heat-resistant cable should be
selected for use with the controller in an application
where the ambient temperature exceeds 70
C.
8. When using and maintaining the product in the
field, cleaning the plastic surface of the product with
dry cloth is strictly prohibited to avoid the risk of
producing electrical spark.
9. The user must not be allowed to replace at will the
electric components of the product on his own to avoid
damage to the intrinsically safe performance of
explosion protection of the product.
10. The user must follow the relevant rules specified
by the product instruction manual, the “13th Section of
Electric Equipment Used in Explosive Gaseous
Environment: Maintenance of Electric Equipment Used
in Explosive Gaseous Environment” of
GB3836.13-1997 standard, the “15th Section of
Electric Equipment Used in Explosive Gaseous
Environment: Electric Installation in Hazardous
Locations (except for coal mine)” of GB3836.15-2000
standard and the “Electric installation construction and
acceptance test code for electric equipment mounting
engineering in an explosive and fire-hazardous
environment” of GB50257:1996 standard while
performing installation, operation, and maintenance for
the product.
Refer to figure B-19 for NEPSI nameplates.
Flameproof
DVC6000f digital valve controllers (designated as
controller hereafter) have been proved to be in
conformity with the requirements specified in the
national standards GB3836.1-2000 and
GB3836.2-2000 through inspections conducted by
National Supervision and Inspection Centre for
Explosion Protection and Safety of Instrumentation
(NEPSI). The Ex markings for the products are Ex d II
B+H2T6/T5 (DVC6010f, DVC6020f, and DVC6030f
only), Ex d II BT6/T5 (DVC6005f only), and Ex d II
CT6/T5/T4 (DVC6015, DVC6025, and DVC6035 only)
respectively and their Ex certificate number is
GYJ06279. When using the product , the user should
pay attention to the items stated below:
1. The correlation of this approved DVC6000f digital
valve controllers in specific product type, Ex marking,
and operating ambient temperature is as follows:

2. The enclosure of the controller provides a
grounding terminal, and the user should install a
reliable grounding wire connected to it when mounting
and using the controller.
3. The controller’s cable entrance (1/2 NPT) must be
fitted with a cable entry device which is Ex-approved
through inspection of explosion protection, in
conformity with relevant standards of GB3836.1-2000
and GB3836.2-2000 and has a corresponding rating of
explosion protection.
4. An appropriate heat-resistant cable should be
selected for use with the controller in an application
where the ambient temperature exceeds 70
C.
5. The principle of “Opening equipment’s cover is
strictly prohibited while it is active” must be abided by
when using and maintaining the controller in the field.
6. The user must follow the relevant rules specified by
the product instruction manual, the “13th Section of
Electric Equipment Used in Explosive Gaseous
Environment: Maintenance of Electric Equipment Used
in Explosive Gaseous Environment” of
GB3836.13-1997 standard, the “15th Section of
Electric Equipment Used in Explosive Gaseous
Environment: Electric Installation in Hazardous
Locations (except for coal mine)” of GB3836.15-2000
standard and the “Electric installation construction and
acceptance test code for electric equipment mounting
engineering in an explosive and fire-hazardous
environment” of GB50257:1996 standard while
performing installation, operation, and maintenance for
the product.
Refer to figure B-19 for NEPSI nameplates.
