Installation - Siemens SITRANS LVS100 Operating Instructions Manual

Installation

Mounting
Notes:
• Installation shall be performed by qualified personnel and in accordance with local
governing regulations.
• Do not bend, shorten or extend the tines.
• Position the tines using a 50 mm open-end wrench when installing the process
connection (do not turn the housing). When side mounting SITRANS LVS100/200,
position the tines vertically, with the tine orientation marking facing up or down.
• In pressure applications, use PTFE tape or other appropriate sealant to seal
tapered threaded connections.
• After mounting, ensure the cable entries point downward to prevent water entering
the housing.
• For the SITRANS LVS100/200 extended model, the torque due to material loading at
the mounting point may not exceed 250 Nm.
• Mounting torque for the 1½" thread connection may not exceed 80 Nm.
WARNINGS:
LVS100 and LVS200:
• This product is designated as a Pressure Accessory per Directive
97 / 23 / EC and is not intended for use as a safety device.
• Improper installation may result in loss of process pressure.
• To install devices in hazardous locations, observe all valid installation
regulations.
• For ATEX installations, observe the requirements of EN 50281-1-2
regarding dust deposits and temperatures. Before opening the device
lid, ensure there are no deposits present.
• Do not remove lid while circuits are live.
• Install the SITRANS LVS100/200 so mechanical friction or impact does
not cause sparks between the aluminium enclosure and steel vessel.
LVS200:
• Installation in Zone 0 (electronics: NAMUR): The intrinsic safe supply
circuit must have galvanic isolation to a non- intrinsically safe area.
Otherwise, provide protection for the device against lightning strikes
(see EN 60079-14).
• Power supply (electronics: NAMUR): Intrinsically safe protection is
only valid when connected to a certified intrinsically safe power
supply.
• For the LVS Pipe extended and cable extended models with Namur
electronics for gas hazardous approvals: When mounting the units on a
vessel lid that separates Zone 0 (Cat. 1G) from Zone 1 (Cat 2G), the units
have no safe separation between Zone 0 and Zone 1. Gas can pass
from Zone 0 through the unit to Zone 1.
