46-648 Jupiter Magnetostrictive Transmitters

2.5 Maintenance

2.5.1 Keep Control Clean

Periodic inspections are a necessary means to keep your

level control in good working order. This control is a safety

device to protect the valuable equipment it serves.

If the process liquid is clean (no solids or deposits), the

MLI should require minimum maintenance. If the process

liquid is dirty (solids and deposits), it is recommended the

external cage be isolated from the process and flushed peri-

odically. For complete cleaning, drain the unit, remove the

bottom flange and float, inspect cage and float for build-

up and clean if required.

2.4.2 Agency Specifications – Explosion Proof Installation

Factory Sealed:

This product has been approved by Factory Mutual Research

(FM) and Canadian Standards Association (CSA) as a Factory

Sealed device.

NOTE: Factory Sealed: No Explosion Proof conduit fitting (EY seal) is

required within 18" of the transmitter. However, an Explosion

Proof conduit fitting (EY seal) is required between the haz-

ardous and safe areas.

Caution: Grounding (+) will cause faulty operation, but will not

cause permanent damage.

Caution: Do not rotate the Jupiter electronics enclosure or any

threaded fittings. Rotating the electronics enclosure will

void warranty and could cause damage to sensor cables.
