Standard, Food Grade and Stub Probe Mounting: (See Figures 3 & 4)

1)Select a mounting location in accordance with the Pre- Installation Recommendations.

2)If using a welded fitting, cut a hole into the side/top of the vessel corresponding to the mounting connection (1-1/4” NPT or 3/4” NPT). If using a mounting plate, cut a 2-1/2 inch (64 mm) center hole and six 11/32 inch(9mm) mounting holes (for 5/16” bolts) on a 7 inch (178 mm)bolt circle. Use mounting plate as a template.

3)Weld fitting or attach mounting plate to vessel wall.

4)Insert probe through fitting. Do not use sealant tapes (e.g. Teflon tape) or putties. When using the 1-1/4” NPT connection, grease threads with anti-seize then thread unit tightly into place by gripping and rotating housing. When using the 3/4” NPT connection, thread unit tightly into place by gripping and rotating 15/16 inch (24 mm) wrench flats provided on fitting. Continuity between sensor mounting point and vessel wall must be maintained to assure proper probe operation.

Factory Wiring:

The LV800 probe wires are connected to the backside of the PCB. DO NOT alter this connection. Doing will likely cause improper operation of the sensor.

Permanently Connected Equipment:

Disconnecting devices shall by included in the system installa- tion. In installations were multiple circuits are used (i.e. inde- pendent circuits for power input and output relay), individual disconnects are required. The disconnects shall be within close proximity of the equipment, accessible to operators, and marked appropriately as the disconnect for the associated cir- cuit. Assure the disconnect ratings are appropriately sized for the circuit protected (See Specifications).

Circuit Separation:

Two cable entry locations are provided to aid in maintaining separation of "hazardous live" (typically mains voltages such as 115VAC and 230VAC) and limited circuits (typically control voltages less than 30Vrms or 42.4VDC). However, since the LV800 single wiring compartment can not absolutely protect against physical contact between multiple circuits, it is required that all wiring used must have an insulation rating of 300V min- imum, and a temperature rating of 80˚ C (176˚ F) minimum.

Protective Earthing:

Each LV800 is provided with a "protective conductor terminal" which shall be terminated to the local earth ground potential to eliminate shock hazard in the unlikely event of internal insula- tion breakdown. Select wire size that can carry in excess of the sum of all circuit's maximum amperage.
