Page 4: Installation
Installation Caution: If equipment is used in a manner not specified by manu- facturer, protection provided by equipment may be impaired. Unpacking Unpack the instrument carefully. Inspect all units for damage. Report any concealed damage to carrier within 24 hours. Check the contents against the packing slip and purchase order. -
Page 5: Mounting
Caution: This instrument is intended for use in Installation Category II, Pollution Degree 2 locations. Adjust piping as required to bring control to a vertical position. Magnetrol controls must be mounted within 3° ® of vertical in all directions. A three-degree slant is noticeable by eye, but installation should be checked with a spirit level on top and/or sides of float chamber. - Page 6 NOTE: Housing must be grounded via protective ground screw in the base of the housing. NOTE: On high temperature applications (above +250° F [+121° C] in float chamber), high temperature wire should be used between control and first junction box located in a cooler area. On non-hazardous applications, flexible conduit may be used between the control and the first junction box.

Page 7: Reference Information
Reference Information Description Flanged External Cage liquid level switches are completely self-contained units designed for side mounting to a vessel or tank with threaded or flanged pipe connections. Theory of Operation The design of float-operated level switches is based upon the principle that a magnetic field will not be affected by non-magnetic materials such as 316 stainless steel The float moves a magnetic attraction sleeve within a... -

Page 11: Troubleshooting
Troubleshooting Usually the first indication of improper operation is failure of the controlled equipment to function, i.e., pump will not start (or stop); signal lamps fail to light, etc. When these symptoms occur, whether at time of installation or during routine service thereafter, check the following potential external causes first. -
Page 12: Check Sensing Unit
Check Sensing Unit 1. Reconnect power supply. Carefully actuate the switch mechanism manually (use a non-conductive tool on electri- cal switch mechanisms) to determine whether controlled equipment will operate. Caution: With electrical power on, care should be taken to avoid contact with switch leads and connections at terminal block. -
