1 GENERAL INFORMATION
Please observe the notes in these operating instructions together with the
conditions of use and permitted data that are specified in the data sheets of
the 0911 controller, so that the device will function perfectly and will have a
long service life.
• Keep to the standard engineering rules when planning and operating the
device!
• Installation and maintenance work may only be carried out by specialist
personnel using the correct tools!
• Observe the current regulations on accident prevention and the safety
regulations for electrical devices during the operation and maintenance of
the device!
• Comply with the intended usage of the device.
• Only operate the device with its housing fitted.
• Before connecting the device, check that the power supply corresponds to
the values printed on the device.
• Check that the connections are correct before switching on the device.
• Observe the maximum load of the relay contacts (see technical data).
• Ensure that all sensors are installed with sufficient separation from voltage-
conducting lines. This will avoid incorrect temperature readings and will
protect the device from voltage interference at the sensor inputs.
• For applications in the industrial sector with critical environments, switch an
RC element in parallel (FT1).
• Always switch off the mains supply before carrying out manipulations on
the system.
• Take suitable measures to exclude unintended operation and damage by
unauthorised operation!

4 ASSEMBLY, INSTALLATION AND COMMISSIONING
4.1 General information regarding the installation and operation
ATTENTION! • Do not lay cables for inputs next to lines carrying voltage.
• Avoid heavy vibrations, aggressive gases, heavy soiling
and damp.
NOTE • Before connecting the device, check that the power supply
corresponds to the values shown on the rating plate.
• Observe the maximum loading of the relay contacts (see
Technical data ).
• Ensure that you install all sensors with sufficient separation
from lines carrying voltage, in order to avoid incorrect
temperature measurements and to protect the device from
voltage interference over the sensor inputs.
Panel Mounting clamp
4.2 Assembly
The device is designed for panel mounting in a 71 x 29 mm cutout, and is
secured with a mounting clamp.
In order to guarantee the front protection of IP65, a rubber seal must be fitted
behind the mounting frame (optional for RG-C).
Thje ambient temperature form problem-free operation lies in the range from
0 ... +60°C.
Ensure sufficient ventilation through the cooling slots.

Panel Mounting frame
Front seal
4.3 Electrical connections
Use cable with a cross-section of max. 2.5 mm2. The device is provided
with the corresponding screw terminals.
Check the auxiliary energy before you connect the power supply
(see Technical data ).
Do not load the relay contacts higher than permitted. If necessary, use a
contactor.

DOWNLOAD (HOT-KEY CONTROL DEVICE)
Switch off the electrical power to the controller, or set it to STAND-BY.
Insert the HOT-KEY up to the stop in the marked position on the controller.
Re-activate the controller.
The default parameters in the HOT-KEY will be automatically written into the
controller. During this time, the message DoL blinks in the display. The
programming procedure is finished after 10 seconds, and normal operation
starts automatically with the new parameter set.
The HOT-KEY can be removed.
5 HOT-KEY function
Writing the stored parameter set from the HOT-KEY into the control device:
end for a correct data transfer
err for a failed data transfer
In this case, briefly switch off the power to the device to repeat the
procedure. If you want to cancel the procedure, simply remove the HOT-
KEY.
The following messages are possible at the end of the data transfer:
UPLOAD (CONTROL DEVICE HOT-KEY)
Insert the HOT-KEY into the provided position when the controller is
switched on again.
Operate 1x with . The message uPL can be seen in the display.
Press the SET button in order to start the data transfer. uPL starts to blink.
You can remove the HOT-KEY again after about 10 seconds.
Writing the current default parameters of the control device into the HOT-KEY:
end for a correct data transfer
err for a failed data transfer
In this case, press the SET button again to repeat the procedure. If you
want to cancel the procedure, remove the HOT-KEY.
