6 Product Installation and General Operation
6.1 Installation
Each CMS supplied consists of the following:
− CMS
− Calibration certificate
− USB Stick which includes: Product User Guides, RMF-View software, accessory product drivers and product
brochures
− Pre-wired 3m cable
− Quick Start Guides
Optional Equipment:
− Circular connector pre-wired with 3m cable
− CMSRDU2 Remote display unit
− 500μm coarse screen filter
− CMSUSBi USB adaptor with pre-wired CMS cable
− CMSETHi RJ-45 adaptor with pre-wired CMS cable
6.1.1 Physical Procedure
− Decide on tapping points in hydraulic circuit
− Locate the unit mechanically and bolt to desired location using fixing holes provided. The CMS must be in a
vertical orientation, with the oil flowing upwards through it
− Wire back to junction box
− Check flow in acceptable range. There needs to be a differential pressure of more than approximately 0.5bar
placed across the CMS, such that a flow of fluid is generated within the range of the unit.
− If there is no suitable differential pressure available, then a flow controller will be needed. One solution is the
pressure compensated flow control valve. This limits the flow to around 200ml/minute for differential
pressures up to 400bar. This should be fitted to the drain side of the CMS (the top fitting).
− Fix mechanically
− Connect hoses or hard pipe from the system
− There must be no extra restriction placed in the drain hose. Do not have a pipe going to a restrictor to
control flow. Any such restrictor must be mounted directly to the CMS drain fitting.
(A)
− Fluid flow must be from the bottom fitting to the top, following the direction of flow arrow on the product
labelling i.e. the bottom fitting is the inlet and the top fitting is the outlet.
− Fit electrical connector, wire back to a junction box.
(A)
This is because any length of pipe between the CMS and a downstream restrictor can act as an accumulator.
Any pressure pulsations (for example from a pump) in the feed to the CMS are then translated into pulsations in
