Control System for Remote Valves via RF
General Description
Galcon’s RRTU is a set of a single transmission station and endless number of receivers
that operate valves. The transmitter is encoded by a card that fits the standard slot in
Galileo 2000 or Galileo Expansion. Each receiver is set to respond to a certain address
that is assigned to a valve in the controller. Many receivers can be set to the same address
but they will all respond to the same valve.
The address of the RRTU is set by special programmer (see below). The address is the
number of the first output whilst the following outputs take the consecutive number. For
example: The numbers of the outputs of a RRTU of 4 outputs set to number 6 are 6,7,8,9.
In order to convert that number of the RRTU output into the Output code of the Open field
system do the following:
1 - The last digit from the left is: 1 – in the case of an odd number and 2 – in the case
of an even number.
2 - The 3 digits after the point are calculated according to:
a. If the number is even – the number is divided by 2.
b. If the number is odd – the 1 divided by 2.
3 - The first digit (before the point) from the left is 2 for RRTU (0 for local and 1 for
CRTU)
For Example: Output that is defined as No. 28 at the field (by the programmer) is translated
into the code: 2.0142. The last number is 2 (because it is an even number), the three digits
after the point are 014 = 28 /2, and the digit before the point is 2 for RRTU.
In the same way Output No. 29 is 2.0151.
