3. Sampler run time testing shall check that the control locks out in the event that the sampler motor,
running in both directions, exceeds 20 seconds running time. On the GSI Sample Sentinel controls,
that is achieved by:
a. Set the control in manual mode
b. Turn the stand-by/sample switch (5) to stand-by
c. Locate terminal X3-13 and open the knife switch installed on it
d. After 20 seconds the control should go into a non-volatile lock out
e. Close terminal X3-13 and reset the control
f. Repeat the test, this time using terminal X3-14
g. Reconnect terminal X3-14
4. In the event that any fault is detected in these tests, the sampler shall not be used until the fault has
been identified and rectified. Failure to do so could result in a serious incident endangering life and
property.
Periodic Inspection
At regularly scheduled intervals, while observing all safety precautions, observe the sampler as it
operates. Inspect for:
1. Check motor and gear reducer cooling surfaces and fans for damage and/or build-up of dust and
debris which might result in over heating. Clean and repair as required.
2. Loose or missing hardware
3. Noisy motor or motor/reducer bearings
4. Overheated motor or reducer
5. Adequate lubricant in gear reducer
6. Loose drive chain
7. Structural damage
8. Rust or corrosion
9. Damaged wiring, including exposed conductors and connections
10. Make sure that all guards are in place and that all warning labels are in place and legible.
, GENERAL SAFETY INFORMATION, explains the purpose and intended location of the
warning signs. Warning signs are an important part of any safety program, replace any missing signs
IMMEDIATELY.
Lubrication
Drive Chain, Sprockets and Idler Shaft
The drive chain, sprockets and idler shaft have been greased at the factory. The chain should be
thoroughly cleaned and re-greased once a year using a multi-purpose grease. The idler shaft should also
be greased at the same time.
Gear Reducer
The gear reducer is shipped filled with oil. Check the oil level every six months and add oil if required.
Under normal sampler operating conditions the oil should be changed once every two years.
Use a gear lubricant with an AGMA #8 rating for normal operating conditions. Use a synthetic gear
lubricant such as “Mobil SHC 634” for extreme operating conditions.
