Process temperature value is seen.
If time proportional control was selected, is seen.
If On-Off control was selected, and are seen.
When the device is energized, selected control form is seen on the display.
If the device is energized while holding key, control form changes and the related message
is seen on the display.
If key is pressed, set value is seen.
When key is released, process temperature is seen again.

Error Messages
For displaying Set value
If this message is seen, it means temperature sensor was not disconnected or over
temperature condition was occurred. When this message is seen, the control output
is de-energized.
If this message is seen, it means the device has a calibration error. In this case, the
device should be sent to RS Components for calibration and testing. When this
message is seen, the control output is de-energized.

Terminal Connection
Use suitable compensation cables. Do not
use jointed cables. Pay attention to the
polarities of the thermocouple cables as
shown in the figure right.
SENSOR INPUT:
Logic output is not isolated from the inner circuits
of the device. Therefore, when using a grounding
thermocouple, do not connect the logic output
terminals to the ground.
1241044 is intended for installation in control panels. Make sure that the device is
used only for intended purpose. The electrical connections must be carried on by
a qualified staff and must be according to the relevant locally applicable
regulations. During an installation, all of the cables that are connected to the
device must be free of energy. The device must be protected against inadmissible
humidity, vibrations, severe soiling and make sure that the operation temperature
is not exceeded. All input and output lines that are not connected to the supply
network must be laid out as shielded and twisted cables. These cables should not
be close to the power cables or components. The shielding must be grounded on
the instrument side.
