PNEG-2175CE CE Compliant Sampler - Model GCE 45 and GCE 90 15
4. General Information
System Description
The GCE Sampler is designed to collect a representative sample of granular, flake, pellet or other
materials in a gravity conveying line.
Sample collection is initiated in response to either an operator’s manual command or a signal
automatically generated by controller logic, usually time-based but which could also be volume or quantity
based. A sample cycle begins when an electric motor drives the slotted sample cutter through the product
flow to collect a sample of the material. The sample flows through the sample cutter and out the discharge
as it travels through the material flow. The sample cutter, when at rest, is situated under one of two dust
seals that seal the sample cutter. The sample from the sample cutter flows into to the sample hopper and
out the 3.00" (76 mm) O.D. discharge tube. The sample, flowing via gravity from the hopper discharge, will
then be routed to a sample divider or directly to the desired sample collection point.
Optional Features
The certified drawings indicate which, if any, optional features are included with a sampling system. Some
of the more frequently specified optional features are briefly described in the following list.
1. Controller arranged to initiate a sampling cycle based on quantity or volume of material passing
through conveying line rather than upon elapsed time periods.
2. ATEX compliant sampler for use in dusty atmospheres and with internal zone designated up to
ATEX zone 21D.
NOTE: ATEX compliant sampler does not include electrical controllers, which must be installed
outside the ATEX zone.
3. Components of special materials, such as stainless steel or nedox coatings.
4. Programmable controls to sequence the sampler and the sample collection equipment.
5. Abrasion resistant linings of urethane, AR carbon steel plate, 304 stainless steel or ceramic tile.
Correct Use of the GCE Sampler
The sampler is designed to be used for automatic, intermittent sampling of free-flowing, granular, flake or
pelleted materials in a gravity conveying line.
In particular the sampler is not designed to be used as follows:
1. Continuous sampling.
2. Sampling liquids, sludges or slurries.
3. Sampling rock, stone, sand, gravel or other highly abrasive materials.
4. Sampling materials prone to sparking on impact.
5. Sampling corrosive materials.
6. Sampling materials with maximum aggregate size greater than 1-3/8" (35 mm).
Any other form of use is a misuse of the sampler and may result in damage or
serious/fatal injury.

4. General Information
16 PNEG-2175CE CE Compliant Sampler - Model GCE 45 and GCE 90
7. Sampling volatile, explosive or highly flammable materials.
8. Use other than when connected directly to a material handling system.
9. Use with either the inlet or outlet exposed such that moving parts can be reached.
10. Use with manual filling of emptying.
11. Use when modified in any way.
12. Use in environmental conditions contrary to those marked on the rating plate.
13. Use underground or in mining processes.
14. Sampling of clean, dust free material is inherent to reducing the risk of a potentiality explosive dust
air mixture forming inside the sampler.
15. Where high levels of dust are anticipated inside the sampler, ventilation and extraction should be
used to reduce concentrations.
16. Operators should be aware of health risks from dusts, mould and other biological agents from
the materials being sampled. Overall design of the facility in which the sampler operates shall
minimize this exposure and personal protective equipment (PPE) shall be used to further reduce
risks if required.

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

Ignition Hazard Assessment - GCE Samplers
Guarding of Moving Parts
GCE samplers have hazardous moving parts which present a risk of serious injury when unguarded.
The samplers operate under automatic control and may start unexpectedly and without warning.
1. Guards are provided to enclose all moving parts except those involved in the sampling process.
2. Moving parts involved in the sampling process shall be made inaccessible at installation by enclosing
both the inlet and outlet of the sampler such that the moving parts cannot be reached by any part of
the human body.
3. Generally this is achieved by close coupling the sampler inlet and outlet to the upstream and
downstream conveying system.
4. Where this is not suitable (ex: open hopper inlet), the installer must ensure access to the moving parts
is restricted in accordance with EN ISO 13857 or through other methods (ex: interlocking controls).
5. Under certain circumstances it may be necessary to remove guards. Only do this when the sampler
and other associated equipment is isolated and locked out from the power supply.
6. Never operate the sampler with the guards removed.

Safety in Maintenance and Servicing
Only suitably competent/qualified persons should carry out servicing or maintenance on the GCE sampler.
The following recommendations should be considered:
1. Safe Access: Samplers may be installed in remote locations and at height. Ideally safe, permanent
access should be provided. However in the event that this is not the case, the service technician
should use safe methods, such as a powered work platform or tower scaffold. It is not recommended
to work solely off a ladder.
2. Safe Isolation: Service and maintenance should be carried out only when the sampler has been
disconnected and locked off from all power/energy supplies and the key remains solely in the
possession of the service technician. The sampler operates under automatic control and will start
without warning. Working in or on a sampler that has not been disconnected and locked out can
result in very serious injury. It may also be necessary to isolate other equipment associated with or
attached to the sampler.
3. Safe Troubleshooting: In extreme circumstances, when troubleshooting a malfunctioning sampler it
may become necessary to observe the sampler operating with guards removed. This should only be
carried out in MANUAL mode and, if the sample control is remote from the sampler, with a second
person manning the controls. Refer to Sampler Controls on Page 23 for information on how to
operate the sampler in manual mode.
NOTE: This only applies where the GSI Sample Sentinel controls are being used. For other control
types, refer to the control manufacturer.
4. NEVER attempt to intervene or work on the sampler when powered up, even when in manual mode.
