CONFIG

This first display screen allows the programming of
the TCM18 control instructions (ALL ON, ALL OFF, or
BY CKT) for high ground/earth leakage current (GND
CUR TRIP), heater operating current (HTR CUR TRIP)
and high temperature trip (HI TEMP TRIP). Noting
the flashing cursor location, press the UP or DOWN
arrow keys to select a new option and press ENTER to
accept. The flashing cursor now moves to the next line
where the process may be repeated.

An “ALL ON” designation indicates that all heater
circuits will trip on the high trip value and will require
the operator to press the ACK key and the condition to
clear before the circuit will reset. An “ALL OFF” setting
will leave all of the circuits in an automatic reset mode
which results in the heater automatically resetting
when the condition clears.

When the configuration set up is “BY CKT”, these
options will be prompted and can be programmed on a
circuit by circuit basis during individual programming of
the alarm/trip set point values.

Note that the “ALL ON” or “ALL OFF” settings are
global and if selected will overwrite any previous
“BY CKT” settings employed.

Press the PROG key at any point to exit for this se-
quence. If left in the program mode, the TCM18 will af-
ter a short wait automatically return to the SCAN mode.
