6-5. HIGH TEMPERATURE
LIMIT SYSTEM
July 2016
A high limit thermocouple is attached to each element and
senses oil temperature. If temperature exceeds 600°F (316°C),
a switch opens and shuts off heat to vat, and an E-10 error
code is displayed. After oil temperature cools to a safe operat-
ing temperature (15-20 min.), the high limit must be manually
reset.
High limit reset switches are located in the front edge of an
electricalpanelontheleftsideoftheunitbesidethelterpan.
Open the left door, depress the raised part of the rocker switch
for the affected well, and release switch. If high limit resets,
the oil starts heating. If high limit does not reset, perform fol-
lowing checkout procedure.
