Note
1) Individual error contacts do not operate if corresponding channel is not installed.
2) If you perform a Channel Contact Output Open / Close check then Error2 is gener-
ated. The reason is that Channel Contact Output is used as Sensor heater power safety
switch, and this turns off power to the heater. If this error occurs, to reset it remove
the channel card then reinsert it (hot swap functions), or turn power OFF then back
ON.
