μC 2 SE - +030220426 - rel. 2.1 - 09.06.2010
7.8 Programming key (code PSOPZKEYA0)
The programming keys PSOPZKEY00 and PSOPZKEYA0 for CAREL controllers are used for copying
the complete set parameters for μC
2 SE.
The keys must be connected to the connector (4 pin AMP) fi tted on the controllers, and can
work with the instruments ON or OFF, as indicated in the operating instructions for the specifi c
controller.
The two main functions (upload/download) that can be selected through two dip-switches
(which are placed under the battery cover). They are:
• Loading to the key the parameters of a controller (UPLOAD);
• Copying from the key to one or more controllers (DOWNLOAD).
Warning: the copying of the parameters is allowed only between instruments with the same
code. Data loading operation to the key is always allowed. To make identifi cation of the key easier
CAREL has inserted a label on which you can describe the loaded programming or the machine
to which you are referring.
IMPORTANT NOTE:
the key can be used only with controllers μC
2
SE that have the same
Firmware version.
UPLOAD - copying the parameters from an instrument to the key:
• open the rear hatch of the key and place the two dip-switches in the OFF position (see Fig.
7.j.a). Close the hatch;
• connect the key to the connector of the instrument;
• press the button on the key and keep it pressed, checking the LED signal sequence: at fi rst it is
red, after a few seconds it becomes green;
• if the sequence of signals is as indicated above, the copying operation has been completed
correctly (green LED ON), the button can be released and the key disconnected from the
instrument; in case of diff erent signals: if the green LED doesn’t turn on or if there are some
fl ashes, there’s a problem. Refer to the corresponding table for the meaning of the signals.
DOWNLOAD - copying the parameters from the key to the instrument:
• open the rear hatch of the key and place the dip-switch n. 1 in the OFF position and the dip-
switch n. 2 in the ON position (see Fig. 7.j.b). Close the hatch;
• connect the key to the connector of the instrument;
• press the button on the key and keep it pressed, checking the LED signal sequence: at fi rst it is
red, after a few seconds it becomes green;
• if the sequence of signals is as indicated above, the copying operation has been completed
correctly (green LED ON), the button can be released; after a few seconds the LED turns off and
the key can be disconnected from the instrument;
• in case of diff erent signals: if the green LED doesn’t turn on or if there are some fl ashes there’s a
problem. Refer to the corresponding table for the meaning of the signals.
The operation takes maximum 10 seconds to complete. If after this period the completed
operation signal hasn’t yet appeared, i.e. the green LED ON, try releasing and pressing the button
again. In the event of fl ashes, refer to the corresponding table for the meaning of the signals.
LED signal error meaning and solution
red LED fl ashing Flat batteries at the
beginning of the
copying
The batteries are fl at, the copying cannot be carried out.
Replace the battery (only on PSOPZKEY00).
green LED
fl ashing Flat batteries at
the end of the
copying (only on
PSOPZKEY00) The copying operation has been carried out correctly but at
the end of the operation the voltage of the batteries is low.
It is advisable to replace the batteries.
Alternate red/
green LED
fl ashing
(orange signal) Not compatible
instrument The setup of the parameters cannot be copied since the
model of the connected parameters is not compatible. Such
error happens only with the DOWNLOAD function, check the
controller code and make the copy only on compatible codes.
red and green
LEDs ON Copying
error Error in the copied data. Repeat the operation; if the problem
persists, check the batteries and the connections of the key.
red LED always
ON Data transmission
error The copying operation hasn’t been completed because
of serious data transmission or copying errors. Repeat the
operation, if the problem persists, check the batteries and the
connections of the key.
LEDs OFF Batteries
disconnected Check the batteries (for the PSOPZKEY00)
Power supply not
connected Check the power supply (for the PSOPZKEYA0)
