7 Troubleshooting / FAQ
7.1 Misuse of Product
− The product should be connected to a power supply within the rating of the product and not wired directly to
the mains.
− This product should be connected to a hydraulic line; this must not exceed the upper pressure limit of the
product
− Connection hoses should never be allowed to lie along the floor when the CMS is installed and in use.
− The operator should follow all standard operating procedures previously set at the operating location as well as
the procedures required by the manufacturer.
− The CMS is not suitable for use in an explosive environment or an ATEX zone, for this refer to the CMSAZ2.
− Over tightening of test points/ hoses can damage threads causing the unit to fail.
− The product is designed with no moving components. Should it be used outside of its fluid viscosity specification
the unit will flag a flow error and invalidate that test result.
7.2 Fault Finding
7.2.1 LED Flashing / Fault Codes
The CMS front panel led indicates a fault by a number of white flashes, with a red background. The number of
flashes indicates the fault code, the screen version will also display the fault code and function:
1. Optical - An optical fault could indicate LED failure or blockage of the optical path. Try flushing with
Petroleum Ether, or return to RMF Systems.
2. Low Flow - The CMS estimates the flow by measuring the transition time of the particles. The Low Flow
warning indicates that the flow rate is below the minimum recommended level
(A)
. Note that the alarm
should be disabled in the settings when used on clean systems, such as flushing/cleaning rigs, where the
particle count could reach 14/12/10 or lower.
3. High Flow - The flow rate is above the maximum recommended level. This will degrade the accuracy of
the particle counts.
4. Logging - Fault with data logging memory.
5. Water Sensor - Fault with the water sensor.
(A) The unit will still work but may be more susceptible to errors caused by pressure fluctuations. This
warning can also come on when there are no particles whatsoever detected, i.e. the fluid is totally
"clean’’. In this case the correct result e.g. 0/0/0 is still generated.
