Security
The integrator Supercal 531 features state-of-the-art technology and is in compliance with EN1434.
If the integrator is operated outside the specifications defined in this manual or is not operated in
accordance with the regulations, all service and warranty claims toward Sontex are null and void.
Local regulations
The following regulations have to be taken into consideration:
Local regulations for electric installations
Local regulations for the use of heat meters
Mounting instruction for the installation of heat meters and temperature sensors acc. to
EN1434-2 and EN1434-6
Voltage supply
If the integrator is mains-supplied, an uninterruptible power supply must be guaranteed
Local regulations for electric installations have to be followed
Over- under- and surge voltages are not permitted
Lightning protection
Preventive measures for lightning protection have to be taken for the mains supply or the bus
systems.
Bus-systems
All bus-systems must have a galvanic isolation on the flow sensor side. Otherwise, the integra-
tor may be destroyed!
Cooling systems
The insulation regulations have to be followed
The integrator always has to be mounted away from the cooling pipe.
Installation
The installation instruction is always supplied along with the integrator. These instructions have
to be followed for the installation and the start-up.
With temperature sensors of a cable length of more than 3 m, shielded temperature sensor ca-
bles have to be used. The shields must be installed correctly with the attached fixing clips.
Please pay attention that all ground contacts of the whole installation (network, external supply,
chase of flow sensor and integrator) have the same potential.
Attention has to be paid to correct grounding!
Seals
Each integrator has to be provided with the necessary seals to avoid unauthorized manipula-
tion.
Calibration-relevant seals must not be damaged or removed! Otherwise, the calibration of the
integrator and all warranty and service claims are void.
User seals may only be removed by authorized personnel for service purposes and renewed
afterwards.
