Maintenance and Service
NOTE: Under certain conditions, some of the maintenance and service functions described here
can be nonfunctional in older versions of the hardware and software of the
SUPREMATouch system. For details, contact the MSA Customer Service.
6.1
Maintenance and Adjustment
The system must be checked at regular intervals [not greater than 6 months] to ensure that it is
functioning properly in accordance with the EN 60079-29-2 and the applicable international, na-
tional, industry-specific or company regulations, and the sensitivity and the zero point of the con-
nected sensors must be adjusted as necessary in accordance with the operating instructions for
the types of sensors connected to the system.
Sensors which are no longer able to generate the minimum signals must be replaced.
Active Sensors
For active sensor [sensors with an output of 4 ... 20 mA], the calibration is to be performed directly
on the sensor in accordance with the relevant operating and maintenance instructions. As default
values, the SUPREMATouch system interprets an input current of 4 mA as 0% of the measuring
range and an input current of 20 mA as 100 % of the measuring range.
NOTE: In the case of sensors which do not transmit a maintenance level during calibration, we
recommend that the measure point be locked during the first calibration in the “Setup/Measure
point” menu.
In the following section, the procedure for checking and correcting the display for active sensors
is described.
Checking and Adjusting the Display After a Sucessful Calibration
If the expected values [0% of the measuring range for a signal current of 4 mA and 100 % of the
measuring range for a signal current of 20 mA] do not appear on the SUPREMATouch, the cali-
bration on the SUPREMATouch must be checked and corrected if necessary.
For this purpose, either the signal current of the connected sensor or a variable power source can
be used. If the signal current of the sensor is used, make sure that the sensor is supplying the
correct values.
Tip: A simple way to correct a possibly incorrectly set measure point consists in changing
the selected type of sensor in the “Setup/Measure Points/Sensor Data” menu. To do this,
navigate to the “Setup/Measure Points/Sensor Data” menu, select any other type of sen-
WARNING
In the case of operation with catalytic combustion sensors: To guarantee the unambiguity of cat-
alytic combustion sensor operation it must be made sure [e.g. by check with hand-held test in-
struments] each time before turning on the sensors and the system that the environmental
atmosphere to be monitored by the sensors is free of combustible gases.
WARNING
Disconnect the power before accessing the unit.
