z.— Whether Whether using the 2551 -XX -11 (with frequency or Digital (S3L) output) or the 2551 -XX -12 (with 4 to 20 mA output), the wiring terminals located on the inside of the yellow cover are identical. All of the connections from the Magmeter to external equipment (PLC, Datalogger, Chart Recorder, Flow meter, J etc.) are made at the large 4 -position terminal connector. When the cover is removed the wiring from the sensor can be seen connected to the smaller terminal block. These connections should always remain connected to prevent I inadvertent damage or miswiring. fThe terminals on the 2551 Magmeter are designed for conductors from 16 AWG to 22 AWG. AWARNING! If the second conduit port is used, carefully drill the opening. (The plastic is too strong to be punched out.) • Secure the Magmeter in a vise to prevent damage or injury. • The plastic inside the port is very thin. Do not allow the drill to penetrate too deeply and damage the Magmeter wiring. JP2 is for factory use only. The user must connect output cables to MAKE NO CONNECTIONS. this 4 -terminal jblock- This blue jumper selects - .

(Digital (S -3L) and 4 to 20 mA will not work if flow is against direction of arrow). • The FLOW arrow decal can be placed directly on the pipe to identify the direction of flow. • Use a cable gland or a liquid tight connector to seal the cable ports from water intrusion. • The yellow housing may be reversed to align the conduit ports as required. • If the Magmeter is installed on a vertical pipe, the conduit ports, should be turned to point downward. • This will prevent condensation from being channeled into the enclosure. • Use plumber's tape or a suitable sealant on cable ports.

Strong acids, caustic substances and solvents or their vapor may lead to failure of the retaining nut. ejection of the sensor and loss of the process fluid with possibly serious consequences, such as damage to equipment and serious personal injury. P,etaining nuts that may have been in contact with such substances, e.g. due to leakage or spilling, must be replaced- +GF+ 2551 Blind Magmeter
