INSTALLATION
Mount the instrument in a location that will not be subject to excessive temperature, shock,
or vibration. All models are designed for mounting in an
enclosed panel.
Select the position desired for the instrument on the panel.
If more than one instrument is required, only two units can
be mounted closely together, either one above the other or
side by side. When mounted together, the mounting collar
will require modification by removing the inside tab from
each collar.
Prepare the panel by cutting
and deburring the required
opening.
From the front of the panel,
slide the housing through the
cut out. The housing gasket
should be against the housing
flange before installing.
From the rear of the panel slide
the mounting collar over the hous-
ing. Hold the housing with one
hand and using the other hand,
push the collar evenly against the
panel until the spring loops are
slightly compressed. The ratch-
ets will hold the mounting collar
and housing in place.
INPUT WIRING
Do not run thermocouple or other input wiring in the same conduit as power leads. Use only the type
of thermocouple or RTD probe for which the control has been programmed. See the "SECURE
MENU" to change between RTD and thermocouple input types.
For thermocouple input always use extension leads of the same type designated for your thermo-
couple.

DIAGNOSTIC ERROR MESSAGES
ACTION REQUIRED
Input signals may normally go above
or below range ends. If not, check
input and correct.
To reset use the INDEX & ENTER
keys. When InPt (input fault timer)
has been set for a time, the outputs
will be turned off after the set time.
Setting the time to OFF causes the
outputs to remain active, however
UFL or OFL will still be displayed.
Correct or replace sensor. To reset
use the INDEX & ENTER keys.
Remove the instrument for service
and / or recalibration. To reset use the
INDEX & ENTER keys.
Remove the instrument for service
and / or recalibration. To reset use the
INDEX & ENTER keys.
Check that the power supply is on, or
that the external fuses are good.
The display alternates between FAIL
tESt and one of the following mes-
sages: FACt dFLt: Memory may be
corrupted. Press the ENTER key and
the DOWN ARROW key to start the
factory default procedure. Re-check
controller programming. rEt FACt:
Can not recover from error, return to
factory for service.
Correct the SP or adjust the SPL or
SPH values by programming new
values.
Correct the SPL or SPH values by
programming new values.

MEANING
Underflow or Overflow:
Process value has ex-
ceeded input range ends.
UFL or OFL will sequence
to display one of these
messages if the InPt is set
for a time value.
For RTD inputs RTD is
open or shorted.
For THERMOCOUPLE in-
puts thermocouple is open.
Check calibration appears
as an alternating message
if the instrument calibra-
tion nears tolerance edges.
Check calibration appears
as a flashing message if
the instrument calibration
exceeds specification.
Display is blank. Instru-
ment may not be getting
power, or the supply volt-
age is too low.
Fail test appears upon
power up if the internal di-
agnostics detect a failure.
This message may occur
during operation if a failure
is detected. Displays flash.
This message will appear
upon power up if the set
point is set outside of the
SPL or SPH values.
This message appears at
power up if SPL or SPH
values are programmed
outside the input range
ends.
