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 with- in 24 hours. Check the contents against the packing slip and purchase order. -
Page 5: Mounting
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. Control 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 com- pletely self-contained units designed for side mounting to a vessel or tank with threaded or flanged pipe con- nections. Theory of Operation The design of float-operated level switches is based upon the principle that a magnetic field will not be affect- ed by non-magnetic materials such as 316 stainless steel The float moves a magnetic attraction sleeve within... -

Page 11: Troubleshooting
Troubleshooting Usually the first indication of improper operation is fail- ure 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 instal- lation or during routine service thereafter, check the fol- lowing 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 electrical 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. -
