Thermon TraceNet TCM 18 - Manual (Page 41)

The flashing cursor now moves to the next line which
allows the operator of the TCM18 to program a certain
amount of time delay for a High Temperature Trip
event. A value other than 0 for this parameter indicates
the operator has chosen to filter out and minimize
tripping the heat tracing circuit for a short term higher
temperature exposure operating event. Press the UP
or DOWN arrow keys to enter a new value and press
ENTER to accept.
Note that all of these values are global and apply to all
eighteen circuits on this TCM18 controller.
Press the PROG key at any point to exit for this se-
quence. If left in the program mode, the TCM18 will
after a short wait, automatically return to the SCAN
mode.

The flashing cursor now moves to a third display
screen. This third display screen allows the operator
of the TCM18 to program the time period in hours be-
tween automatic heat tracing self test events. A self
test will check for functionality of the relays (by turn-
ing each heat tracing circuit relay on and then off and
making sure that there is a difference in the heater cur-
rent read). Press the UP or DOWN arrow keys to en-
ter a new value and press ENTER to accept. Pressing
the ENTER key when “RUN” is selected immediately
invokes a SELF TEST. This setting does not change
the programmed the time period. Selecting the “OFF”
option deactivates the self test function.

The flashing cursor now moves to the next display
screen which allows the operator of the TCM18 to pro-
gram the amount of start-up delay in minutes for this
TCM18 module. This option permits a staggered start-
up for a grouping of TCM18 modules. Press the UP or
DOWN arrow keys to enter a new value and press EN-
TER to accept.
