2.1.6. Analog output module (AAM)
The employment of up to eight AAMs with a total of 64 outputs allows
transmission of detector signals (4-20 mA or 0-10 V).
An address between 1 and 8 is allocated to each module by rotary switch.
ATTENTION!
Though the AAM has two microcontrollers, only one controller is able to
transmit data to the outputs. This is generally done by controller B. Since this
will block transmission of measured values by controller A, same will be
considered as faulty and the LED for fault will light up in red.
Should controller B be faulty, controller A will take over transmission of
measured values to the outputs. In this case, the LED of controller A will light
up in green and that of controller B in red.
2.1.7. LCD module
The system WinPro
®
/ MX62 can be equipped with a graphic LCD
display (240 x 128 pixels) showing information of measuring points, all
relevant system parameters, system events and histograms.
The LCD module is provided with an integrated data logger with a storage
capacity of up to 64 MB.
2.1.8. Logo module
If the optional LCD module is not used, the logo module will serve for
display of the four LEDs indicating the status of the system. The logo
module consists of the logo panel plus pertaining PCB.
