Calibration
Each analog output of the M2400 can be calibrated separately.
The output that is to be calibrated has to be enabled by the corresponding relay.
For zero voltage calibration the 12 bit data word 800H has to be transmitted to the M2400.
Zero voltage is calibrated by the potentiometer 'OFFSET'.
For calibration of gain the 12 bit data word FFFH or OOOH is transmitted to the M2400. The
analog output is calibrated by the potentiometer 'PITCH' to either -10V or +10V.
The potentiometer for adjustment and the default value can be found on the module after
removing the small lid below X20.
The default output value is fixed to or by factory preset. Activation of level potentiometers is
done by cutting a marked piece of copper trace on the pcb
Power Supply
The following connectors are used for powers supply :
(1) two pole plug connection for control logic (X10 Pin1+2)
(2) two pole plug connection for outputs (X30 Pin1+2)
(16 outputs)
(3) two pole plug connection for inputs (X31 Pin1+2)
(16 inputs)
(4) two pole plug connection for ground (X32 Pin1+2)
