[TRNSYS-users] Enquiry about Type536

Dear all.

I am sorry if this question had been raised before.  I recently use to 
linear parabolic concentrator (Type536) to model a solar cooling system. 
  However, I find that if the number in series (Parameter 1) exceeds 10, 
the following error occurs.


*** Fatal Error at time   :         0.000000
     Generated by Unit     :    21
     Generated by Type     :   536
     TRNSYS Message    125 : The referenced Unit has a bad parameter 
value.
     Reported information  : Parameter # 1, Reported Problem: The number 
of collectors connected in series must be at least 1 and less than the 
maximum.


I cannot find any hint in the manual.  As I am using TRNSYS17, I don't 
have the source code.  Does anyone know what's going wrong?  Moreover, I 
find that if the total number of solar collectors remain the same, the 
connection configuration (combination of Parameters 1 and 2) of the 
solar collectors do not seem to have any evident effect on the system 
performance.  Does anyone encounter this before?  Finally, is it common 
that tracking be provided when this kind of solar collectors are used in 
actual practice, as the model itself does not offer this option?  Thank 
you!
