• EN 61326-1 • FM 6520 [in oil version only] 4. ELECTRICAL INTERFACE All electrical connections to the GRIDSCAN 5000 Hydrogen Monitor are supplied through a single four-pin M12 connector. 4.1 CONNECTOR The key (notch) location and pin numbers are shown in Table 3. -
Page 9: Cable
The GRIDSCAN 5000 does not include bias resistors for the Data lines which may need to be added at the SCADA end of the cable. A 120 ohm termination resistor, between Data+ and Data- is installed in the GRIDSCAN 5000. -
Page 10: Mechanical Connection
• Keep the red protective cap in place until the time of installation. • Place a wrench on the metal housing closest to the threaded end when tightening. The GRIDSCAN 5000 is designed to handle torque throughout the whole sensor assembly enclosure. - Page 11 • When installed in oil, provide a method to bleed all air from pipe fittings between sensor and oil tank. • Do not install monitor in turbulent oil flow. See Figure 4 for mounting locations. Figure 4: Typical Locations for GRIDSCAN 5000 Installation 90000177 R8 ECO 24-184...

Page 12: Bleeding Air From The Installation
5.2.1 Bleeding Air from the Installation Once the GRIDSCAN 5000 has been installed onto the desired location, any air trapped in the assembly must be removed. The following steps are general in nature and will depend on the specific hardware being used. -
Page 13: Optional Accessories
The grounding lug provides a secure earth ground connection to GRIDSCAN 5000 independent of the plumbing used to make an oil (or headspace) connection. 5.4.2 Conduit Adapter The conduit adapter provides a method of installing the GRIDSCAN 5000 cable in conduit from the control panel to the sensor. 5.4.3 Analog Output Adapter The analog output adapter converts the digital Modbus signal from the GRIDSCAN 5000 to a 4–20mA analog... -
Page 14: Monitoring
If the sensor element is damaged and inoperable, the GRIDSCAN 5000 will shut down the measurement system and continue responding to Modbus requests for error reporting. This error will be reported via register 111 bit 12 and details specified in registers 112,113. - Page 15 Zip file tool. 2.
