X-50 Mounting and operating instructions
Intended use
The device is to be used in dry interior areas. For applications in Ex areas or in contact with water or other liquids no
liability can be assumed.
Installation instruction
The installation may only be carried out by authorised experts in accordance with valid regulations (EN1434 Part 6 Reg-
ulations and Recommendations for Installation and Operation) and/or the recommendations of specialist organisations
(such as the AGFW series Codes of Practice for District Heating.
Important:
The totaliser, the paired sensors and the flow meter of a measuring point are to be compatible with one another
and should not be replaced.
Verified instruments are lead sealed. These seals should not be damaged or broken in any way.
Measuring instruments have to be treated with caution. To protect from damage and contamination, the packing should
be removed just before installation.
Verify, if the sensor (e.g. Pt500) is suitable for the calculator. Pay attention to the correct installation side (warm
side, cold side) of the flow meter.
Verify the pulse value of the flow meter and the totaliser according to the labels. Pay attention to the flow direction
of the flow meter.
Verifiable parameters or other service parameters can only be changed in the field if the instrument is not a verified unit.
Documentation is available on request.

Main loop
The main loop shows the most important readings and provides access to subloops.
High accurate readings can also be displayed when both keys are pressed simultaneously.
The meter readings of the calculator can be adjusted to external counters in Service- or Program-Mode. Changes in
Program-Mode can only be changed if the instrument is not a verified unit.

Remove the totaliser module and check that option board is correctly mounted and that the selector switch(es) is/are
set to Position "In". Carry out the settings of the pulse input.
The adjustments of the auxiliary inputs (No. 2 and No. 3) have an effect only if they are physically available.
The auxiliary inputs (No. 2 and No. 3) can be set in the Service Mode [S-Edit] .
Note: Before adjusting the pulse value, you have to choose the unit in the units loop.
Settings of the main input (No.1) are verifiable. They can only be changed if the seal is broken [P-Edit].
