Menu Function RS232
This menu is used to set the rate of transfer and the data to be output on the serial interface.
Connections can be made to a qualified printer or pc programm “hyper terminal”. Fixed settings: data
bits 8, stop bits 1, parity none, protocol none
3.6.1 Menu Function RS232->Output
Settting type of output:
OFF:
Serial interface is deactivated
single alarm: at every alarm or fault, ouput the relevant measuring
cyclic:
The values measured at all measuring points are output at adjustable intervals. The
intervals can be set from 1 to 30 minutes. Also alarms and faults are output as in
single alarm mode

Maintenance work
The following maintenance work to be carried out, refers to a twice-yearly check that should be
completed only by fully trained personnel.
The owner or operator of the system is offered the possibility of completing a maintenance contract
with the manufacturer, the ADOS GmbH company, which will guarantee a smooth and efficient
servicing by the company's own customer service.
The maintenance work can be divided into checking the sensor functions and checking the complete
gas monitoring unit, MWS897.
Over a period of time, the properties of the sensors can change. Therefore, on all sensors fitted to the
system, the relevant checks must be made as described in the operating instructions, to check the
calibration with zero gas and calibration gas.
Because of the changes that are possible, after establishing that the sensitivity of the sensors is not
sufficient, they must be re-calibrated or where necessary, replaced by new sensors.
The accuracy of the signals on the interface and the function of the output signals from the gas
monitoring unit, must also be checked regularly.
