3.20.1 Analog I/O Option MCB 109, 26-**
The Analog I/O Option MCB 109 extends the functionality of ADAP-KOOL DriveAKD102 Series frequency converters, by adding a number of additional,
programmable analog inputs and outputs. This could be especially useful in Building Management System installations where the frequency converter
may be used as decentral I/O, obviating the need for an outstation and thus reducing cost.
Consider the diagram:
Readout of the value for Compressor ON Time. The Cascade Controller has separate counters for
the compressors and for the relays that control the compressors. Compressor ON Time monitors
the "operating hours" of each compressor. The value of each Compressor ON Time counter can be
reset to 0 by writing in the parameter, e.g. if the compressor is replaced in case of service.
Readout of the value for Relay ON time. The Cascade Controller has separate counters for the
compressors and for the relays that control the compressors. Compressor cycling is always done
based on the relay counters, otherwise it would always use the new compressor if a compressor is
replaced and its value in par. 25-85, Compressor ON Time counter is reset. In order to use par.
25-04, Compressor Cycling, the Cascade Controller is monitoring the Relay ON time.
Function:
Relay ON Time
Resets all elements in
Function:
View the inverse interlock status of the connected compresors. Represented binary with compressor
1 rightmost and compressor 8 leftmost.
In this parameter, it is possible to disable one or more of the fixed lead compressors. For example,
the compressor will not be selected for staging on even if it is the next compressor in the operation
sequence. It is not possible to disable the lead compressor with the Compressor Interlock command.
The digital input interlocks are selected as
par. 5-1*.
The compressor is active for staging/destaging.
The Compressor Interlock command is given. If a compressor is running it is immediately destaged.
If the compressor is not running it is not allowed to stage on.
