-
the number of addressable elements in a detection line must not exceed 127;
-
the maximum current consumption of all elements installed in the line must not exceed:
20 mA in a quiescent mode at the detection line cabling resistance of 2 x 100 Ω,
22 mA in a quiescent mode at the detection line cabling resistance of 2 x 75 Ω,
50 mA in a quiescent mode at the detection line cabling resistance of 2 x 45 Ω,
the detection line cabling capacity must not exceed 300 nF.
6.2 ADDRESSABLE ELEMENTS NUMBERING
In the POLON 4000 system, each addressable element has a unique 12-digit number (factory
number) but the control panel, during its normal operation, refers to addressable elements via their
element numbers (short number of the 1 ÷ 127 range). During the detection lines configuration, the
serial numbers of addressable elements are assigned to the consecutive element numbers.
Three methods of the POLON 4000 system addressable elements configuration can be applied:
-
automatic configuration,
-
configuration with verification,
-
manual numbering.
6.2.1 Automatic configuration
The elements located in the main loop are numbered consecutively starting from 1 from the side of
the terminals marked as Lx, up to the closest branch. Next, the control panel numbers the elements
located in the branch to its end. After the numbering process is finished in the branch, the system
returns to the main loop and numbers the elements to the next branch and then continues
numbering the elements within the branch according to the above mentioned procedure. This
process is continued until all addressable elements are numbered.
In this numbering method the elements are always allocated with consecutive numbers from 1 to n.
6.2.2 Configuration with verification
In this option it is necessary, on the basis of the circuit design and the control panel number
allocation algorithm, to carry out a pre-declaration, i.e. to assign (from a keyboard or computer file)
an element type to each number. Then a verification option should be run at the control panel. In
case the element types declared for given numbers are consistent with the element types allocated
in accordance with the required algorithm, the control panel automatically gives numbers to the
addressable elements.
6.2.3 Manual number allocation
This method allows to assign numbers to addressable elements arbitrarily. Matching factory numbers
with element numbers is carried out by typing the element number in the factory number box
manually.
Manual number declaration in the whole detection line enables arbitrary elements configuration in
this line (numbers allocation can be performed in any order, not necessarily abiding the numeration
order.
Notes:
The ADC-4001M adapter with incorrectly assigned number can produce a detecting line overload. It
is necessary to take the adapter out from its base and wait for at least 5 minutes. Reinstalled adapter
shall draw only 150 μA from the line (the side line is automatically blocked). Before the adapter side
line re-enablement, it should be assigned a proper operation mode in accordance with the
programming manual.
