2.2 Connection of third party sensors
DS 52 has one analogue sensor input for connection of sensors with 0/4…20
mA signal.The sensor input is configurated on our premises (according to the
customers specification in the order).
Sensors with 0/4…20 mA-current signal are connected as follows:
V+ max:
24 VDC
100 mA
* A bridge circuit is inserted ex factory . For signal transfer please remove the
bridge circuit and attach the connection cables. Attention: Current loop has

5. Calibration/adjustment
At CS Instruments
According to DIN ISO certification of the measuring instruments we
recommend to calibrate and if applicable to adjust the instruments regularly at
the manufacturer. The calibration intervals should comply with your internal
specificaton. According to DIN ISO we recommend a calibration interval of one
year for the instrument DS 52 including probes.
6. Warranty
If you have reason for complaint we will of course repair any faults free of
charge if it can be proven that they are manufacturing faults. The fault should
be reported immediately after it has been found and within the warranty time
guaranteed by us. Excluded from this warranty is damage caused by improper
use and non adherence to the instruction manual.
The warranty is also cancelled once the instrument has been opened - as far
as this has not been mentioned in the instruction manual for maintenance
purposes - or if the serial number in the instrument has been changed,
damaged or removed.
The warranty time for DS 52 is 12 months, the warranty time of the accessories
is 6 months. Warranty services do not extend the warranty time.
If in addition to the warranty service necessary repairs, adjustments or similar
are carried out the warranty services are free of charge but there is a charge
for other services such as transport and packaging costs. Other claims,
especially those for damage occurring outside the instrument, are not included
unless responsibility is legally binding.
After sales service after the warranty time has elapsed
We are of course there for you even after the warranty time has elapsed. In
case of malfunctions please send us the instrument with a short-form
description of the fault. Please do not forget to indicate your telephone number
so that we can call you in case of any questions.
