14.2 Dry-running protection for centrifugal pumps by active power
monitoring
14.2.1 Module integration
The function "dry-running protection for centrifugal pumps by means of active power
monitoring" is implemented in the following modules:
● Basic units with PTB 18 ATEX 5003 X:
– 3UF7010-1A.00-0 from *E16*
– 3UF7011-1A.00-0 from *E13*
– 3UF7013-1A.00-0 from *E04*
● 3UF712 current/voltage measuring modules
You must to use a combination of both modules to realize this function.
14.2.2 Information and standards
Information and standards
Dry-running protection for centrifugal pumps by active power monitoring – type of ignition
protection b
Monitoring systems against dry running are one of the elements required to ensure the safe
operation of centrifugal pumps in hazardous areas.
SIMOCODE pro is a safety, controlling or regulating device intended to work autonomously.
SIMOCODE pro corresponds to the requirement level for a b1 ignition protection system for
centrifugal pumps that are suitable for pumping flammable media and are installed in
hazardous areas.
SIMOCODE pro is not suitable for installation in hazardous areas.
The device is only allowed to be installed in a control cabinet with the minimum degree of
protection of IP 4x.
If installed in hazardous areas, there must be no ignition hazard originating from the device.
Appropriate measures must be taken (e.g. encapsulation).
