RAYCHEM E507S-LS Mechanical Thermostat

Description

RAYCHEM E507S-LS Mechanical Thermostat is a line-sensing thermostat designed to control heat tracing systems in hazardous locations. The E507S-LS senses pipe or tank wall temperatures, used to control a single heat tracing circuit or switch multiple circuits with a contactor, it has an adjustable set point. Also used to indicate low temperature or high temperature alarm conditions.

• INSTALLING THE THERMOSTAT RAYCHEM E507S-LS:

  •  Verify that the thermostat issuitable for the area where it is to beinstalled.
  • Check the line voltage and the heat-tracing load to ensure that the thermostat ratings are not exceeded
  • Mount the unit using unistrut or the RAYCHEM universal mounting bracket (UMB-263757) in a position that prevents condensation from draining into the enclosure from the connecting conduit (see diagram above)

• POSITIONING THE SENSOR BULB:

  • Position the bulb in the lower quadrant of the pipe as shown in the diagrams to the left. Place the bulb at least three feet from pipe supports, valves, or other heat sinks; protect the capillary from kinks or bends less than 1⁄2 inch in radius.
  • Tape the bulb firmly to the pipe with AT-180 aluminum tape, making sure there is no air space between the bulb and pipe. Do not overlap the bulb and heating cable with the same piece of AT-180 tape.
  • For metal-tank-wall sensing, use the BCK-35 bulb clamp (purchased separately) and install the clamp per the instructions provided. Make sure there is no air space between the tank wall and the bulb.
    • For installation on plastic tanks, please contact.

• SETTING THE THERMOSTAT:

  • Set the thermostat dial to the desired temperature, then finish wiring.
  • Complete insulating. Do not turn the system on until the bulb is covered with thermal insulation.
  • Fill the piping or tank. Once the thermostat has begun to cycle, check the fluid temperature with an immersed thermostat (best for plastic systems) or an accurate temperature indicator. Adjust the dial setting if necessary
