Check the error log to find out the vat temperature at
the time the high limit tripped. If this temperature was
very low, this may be a sign that the vat was turned on
with low or no oil. If this was the case, fill the pot with
oil and reset the high limit. If the high limit tripped at a
higher temperature, inspect the high limit thermocou-
ples for carbon build up and clean if necessary. If no
carbon found, see 1.13 High Limit and Module Inspec-
tion , page 16 5.6 High Limit Thermocouples Re-
and
placement , page 74.

A "good" reading from the sensor is between 0.5v (0
PSI) and 4.5v (30 PSI). Tolerances beyond those va-
lues are allowed:
- Low reference value less than 0.25v
- The "unplugged" condition should generate an E-
13A. A pull-down resistor on the CPU board pulls the
input low if disconnected.
Any E-13 error allows operators to cook on the fryer;
however, the control disables the pressure for the en-
tire cook cycle unless the E-13 condition resolves with
a good probe readings.

PSI) and 4.5v (30 PSI). Tolerances beyond those va-
lues are allowed:
- High reference value more than 4.75v
