In the table on page 38 you will find the Network Load (NL)
value for each SimNet product, if not look in the technical
specifications for that product.
This is how you determine the System Size Factor (SF):
1. Add all the NL’s to get the total network load = NLtot
2. Add up the total cable length excluding the 30 meter (99’)
wind sensor cable but including the effect of an extended
power cable as explained on page 14. Resulting cable
length = Ltot
3. Determine the System Size Factor; SF = NLtot • Ltot
The following paragraphs refer to systems with a system factor
below 600 (medium), between 600-2000 (large) and above 2000
(extra large).
Note ! The above calculations were based on the Ltot being measured
in meters. If the Ltot is measured in feet, multiply by 0.3 to
determine the System Size Factor, SF.
SF = NLtot • Ltot(feet) • 0.3
Medium system (SF<600)
In a medium system you need the SimNet power cable with built
in termination (red disc on plug) at one end and a wind sensor
(has built in termination), or a termination plug in the other end
of the network. You may use drop cables but observe the
limitations given in the technical specifications (page 11).
