13. Programming key (code PSOPZKEYA0)
The programming keys PSOPZKEY00 and PSOPZKEYA0 for Carel controllers are used to copy the complete set of parameters to the µRack.
The keys must be connected to the connector (4 pin AMP) on the controllers, and can operate when the instruments are either on or off, according to the
instructions for the specific controller.
There are two main functions, which are selected using the two dipswitches (located under the battery cover). These are:
• Load the parameters from a controller to the key (UPLOAD);
• Copy from the key to one or more controllers (DOWNLOAD).
Warning: The parameters can only be copied only between instruments with the same product code. The upload operation, on the other hand, is always possible.
To assist the identification of the key to be used, CAREL has applied a label that can used to describe the programming made or the unit that the data refers to.
IMPORTANT NOTE: The key can only be used on µRack controllers that have the same firmware version.
Refer to the programming key instruction sheet for further details.
14. Supervisor management
The controller can be connected to a local or remote supervisor/telemaintenance system for managing the unit.
The variables sent and received by the supervisor are shown in the tables below, with reference to the following key:
R Read Send from the µRack to the supervisor. Not modifiable
R/W Read- Write Received and sent from the µRack to the supervisor. Can be modified by the supervisor.
