PNEG-2175CE
CE Compliant Sampler - Model GCE 45 and GCE 90
Safe Access
The GCE sampler may be installed at heights and as part of a larger material handling system. To ensure
correct and safe maintenance, servicing and repair can be carried out, safe access to the sampler is
required.
1. Suitable fixed ladders or stairs in accordance with EN ISO 14122-3 or EN ISO 14122-4.
2. Suitable working platform, in accordance with EN ISO 14122-2, providing access to all parts of
the sampler.
ATEX Compliance
GCE samplers may be specified for use in or containing a potentially explosive environment.
1. Classification of the ATEX zone on site is the end users responsibility, but shall be limited to zones
21 or 22 (dusts). Use in all other zones is prohibited.
2. Samplers must be ordered, specified and marked according to the designated zone.
3. Compliance and use in an ATEX zone requires use of a safety control system (control of ignition
sources). Refer to
CE Control Electrical Layout on Page 28
for more details.
ATEX Control Requirements (Zones 22 and 21)
1. To prevent excessive motor temperatures, the motors are provided with internal thermal switches.
These must be installed into the control system in the locations provided or, for non-GSI controls, in
the location identified by the control manufacturer.
2. Where user designed controls are used, the controls shall be designed to provide a minimum level
of ignition protection b1 or be designed to meet the requirements of control of ignition sources to
explosion protection level (EPL) Db, in accordance with EN80079-37.
3. User supplied controls, in addition to the requirements given above, shall include:
a. Motor over temperature control and/or monitoring. Motor temperature shall not exceed 100°C.
b. Sampler over speed detection. Sampler speed shall not exceed 1m/s.
c. Sampler motor maximum run time shut off. The sampler motor shall not run for longer than 20s.
This feature is required to ensure that the clutch fitted to the sampler is not slipping, resulting in
potential high surface temperatures and potential sources of ignition. Maximum surface
temperature shall not exceed 100°C.
4. Where any of the limits stated above are exceeded, the control shall bring the sampler to a stop and
shall not allow restart without direct intervention from the operator. This shall only be permitted once
the cause of the fault has been identified and rectified.
5. These functions shall be testable. (See testing ATEX controls
