1–3 Programming Port and DIP Switch
The programming port is used for off-line automatic setup
and testing procedures only. Do not attempt to make any
connection to these pins when the unit is being used for
normal control purposes.
When the unit leaves the factory, the DIP switch is set so
that TC and RTD are selected for input 1 and all parameters
are unlocked.
Lockout function is used to disable the adjustment of
parameters as well as operation of calibration mode.
However, the menu can still be viewed even under lockout
condition.
*SEL1-SEL5 represent those parameters which are
selected by using SEL1, SEL2,...SEL5 parameters
contained in the setup menu. The parameters that have
been selected are then allocated at the beginning of the
user menu.
