SYMPTOM
CCO/PROBE
(1) or (2) FAIL
Various
PROBLEM
NO CLOCK PRESENT
The real time clock was not found on the board.
No data logging or time sampling is allowed.
LOOP > 20 mA
The calculated value for the loop output is
greater than 20 mA. The loop output will be in
its fail-safe mode.
LOOP < 4 mA
The calculated value for the loop output is less
than 4 mA. The loop output will be in its
fail-safe mode.
DISPLAY IS TOO
DIM OR TOO LIGHT
SOLUTION
Consult Extended Errors section on page 23 of
this manual.
If you need the real time functions, contact
the factory to determine if your unit was ordered
with the data logging option.
If the level is within a normal operating
range, adjust the loop parameters to allow
proper tracking of the level. If the level is out of
the normal 4–20 mA range, then correct the
problem with the level.
If the level is within a normal operating
range, adjust the loop parameters to allow
proper tracking of the level. If the level is out of
the normal 4–20 mA range, then correct the
problem with the level.
Turn R11(contrast adjustment) clockwise to
darken the display or counterclockwise to lighten
the display until the desired contrast is obtained.
