A new display screen appears which indicates the
HIGH TEMP SEEN value, which is the highest tem-
perature that has been measured on the designated
RTD(s).
The flashing cursor moves to the RESET
and allows the operate to erase the restored historical
value on the designated RTD(s) by selecting the “N” for
a no answer or by using the UP or DOWN arrow keys
to change to “Y” for a yes answer.
Where the ALL circuits option has been selected in
this programming sequence, the display screen will not
show the present highest temperature seen values of
all heat tracing circuits on this TCM18 but will reset
ALL of the Highest Temperature Seen values to the
present reading values without further review.
In the unlikely event of an RTD fault where the present
reading is out of normal range, the TCM18 will set
the new Highest Temperature Seen to an extreme
low value such that as soon as the RTD is repaired,
the new highest temperature seen will replace the
abnormal value.
Press the PROG key at any point to exit from this se-
quence. If left in the program mode, the TCM18 will af-
ter a short wait automatically return to the SCAN mode.

If the operator has selected to choose trip preferences
by circuit under the CONFIG key, an additional third
screen display will prompt for the operator to indicate
a “Y” to confirm that TRIP functionality is desired for
this parameter on the displayed circuit.
