Maximum length of guide tubes
According to the length and the execution of the guide, transmitters ADF must possibly
fixed with bottom of the tank.
Electrical hookup
The voltage must be disconnected when electrical connections are being carried out in
the terminal connection box.
The type of protection depends on appropriate choose and installation of cable glands
and blanking elements. Only cable glands with existing, separate EC-type examination
certificates corresponding to EN 60079-0 and EN 60079-1 are applicable. These certified
components have to at least fulfil minimal requirements of temperature range as the
temperature range of the level transmitter gauge. It has to be considered to use
appropriate type and size of threads as the type of apparatus' threads. Use of individual
conductor strands is not permissible!
AL-ADF magnetic float level switches must only be operated on electrical power circuits with
maximum levels as follows:
Maximum voltage:
250 V AC (V.eff)-250V DC
Maximum current:
1,5 A AC (V.eff) 1,5 A DC
Maximum power:
100 VA
Level Regulator switches AL-ADF
The electrical data on the type plate and the additional regulations governing intrinsically safe circuits must
be complied with. This work must be done by trained specialist personnel.
The electrical connection of the Float Switches
AL-ADF
is realized with integrated terminals.
See the connection diagram inside the terminal box or included with the equipment, or the information in
catalogue 1003-
… for the applicable connection scheme.
