- Page 4 The MOP301 is dedicated for reliable and accurate monitoring of lubrication, hydraulic and insulation oils as well as diesel fuel. In addition to highly accurate measurement of water activity (aw) and temperature (T), the MOP301 calculates the absolute water content (x) in ppm.
- Page 5 1.2.3 Mounting, Start-up and Operation The MOP301 moisture in oil probe has been produced under state of the art manufacturing conditions, has been thoroughly tested and has left the factory after fulfilling all safety criteria. The manufacturer has taken all precautions to ensure safe operation of the device.
- Page 6 3 Product Description General The MOP301 is a robust probe for moisture in oil and temperature measurement. Its IP66 rating and the E+E proprietary sensor leads protection make it ideal for highest requirements. It features a moisture in oil measuring range of 0...1 aw, a temperature measuring range of -40...120 °C (-40...248 °F) and a 20 bar (290 psi) pressure...
- Page 7 The manufacturer cannot be held responsible for personal injuries or damage to property as a result of incorrect handling, installation, wiring, power supply and maintenance of the device. The relations of electrical potential between a bus system and an MOP301 probe are characterized by the following properties: ▪...
- Page 8 NOTICE ▪ If the MOP301 is installed in equipment with moving parts, e.g. in gears, it has to be ensured that the probe does not touch any of these parts. ▪ In moving oil, the mechanical stress on the probe is minimized by placing only the filter cap into the flow.
- Page 9 ±40 °C (±72 °F) from the regular temperature during normal operation. NOTICE Replace the metal sealing ring (refer to Fig. 3 Installation of the MOP301 probe directly into the process) by a new one every time before re-installing the probe.
- Page 10 User Manual MOP301 Probe Installation with Ball Valve The ball valve allows for installation and removal of the probe without process interruption. For mounting into the pipe, the ball valve shall be installed perpendicular to the flow direction. INFO There are ball valves available as accessory with G 1/2" thread (order code HA050101) and with 1/2" NPT thread (order code HA050104).
- Page 11 Sampling Cell with Shut-off Function The sampling cell with shut-off function is designed for placing a MOP301 in a bypass oil sampling or as well directly into the process. In both cases, the sampling cell could be moved into the oil flow or in service position by interupting the oil flow.
- Page 12 Sampling cell with shut-off function position “open” (left) and position “closed” (right) 5 Setup and Adjustment The MOP301 is ready to use and does not require any configuration by the user. The factory setup of MOP301 corresponds to the type number ordered. Please refer to the data sheet at www.epluse.com/mop301. The user can change the factory setup with the help the PCS10 Product Configuration Software and the Modbus configuration adapter (order code HA011018).
- Page 13 User Manual MOP301 NOTICE The MOP301 may not be connected to any additional power supply when using the Modbus configuration adapter HA011018. HA011018 Fig. 6 MOP301 connected to a PC running PCS10 Besides an individual probe naming, the communication parameters may be changed and the custom Modbus map can be configured.
