USE OF THE PAGE BUTTON
The “PAGE” button accesses parameter LISTS
Parameters are settings in the instrument which, generally, can be changed by the user to
suit the process. Examples are: Alarms, Self-Tune, etc. They are found under headings
called LISTS and a full set is given later in this chapter.

OPERATING MODES
The controller can be used in two modes:
Automatic mode - in which the output power is automatically adjusted to hold the
temperature at the required value. The controller normally operates in this mode.
Manual mode - in which the output is manually adjusted by the Operator. In this mode
the ‘MAN’ light will be on.
One other mode is available:
Remote setpoint - The setpoint is generated as an input signal from a master CN2216
series controller. In this mode the REM light is on.

SUMMARY
To step through list headers, press the Page button until the required header is
obtained
To step through parameters within a particular list, press the Scroll button until the
required parameter is obtained
Manual mode is generally used for test and commissioning purposes, take care
not to leave the controller in this mode since damage or personal injury could
occur.

What it means What to do about it
Electrically Erasable
Memory Error:
The value of an operator
or configuration
parameter has been
corrupted.
Sensor Break:
Input sensor is unreliable
or the input signal is out
of range.
Loop Break:
The feedback loop is
open circuit.
Load failure
Indication that there is a
fault in the heating circuit
or the solid state relay.
Solid state relay failure
Indication that there is a
fault in the solid state
relay
This fault will automatically take you into
configuration level. Check all of the
configuration parameters before returning to
operator level. Once in operator level, check
all of the operator parameters before
resuming normal operation. If the fault
persists or occurs frequently, contact Omega .
Check that the sensor is correctly connected.
Check that the heating and cooling circuits
are working properly.
This is an alarm generated by feedback from
a Omega SSC-TE10S solid state relay (SSR)
operating in PDLINK mode 1-see Electrical
installation Chapter 2. It indicates either an
open or short circuit SSR, blown fuse, missing
supply or open circuit heater.
This is an alarm generated by feedback from
