PF-6
CAUTION : The probes operate under low voltage and are isolated from
the power supply. Be sure the probe cable is isolated from all high
voltage sources. Do not route the probe cable and other power cables
through the same electrical knockout. Do not run the probe cable next to
other power cables. When crossing over other power cables, cross at
90°.
3. CONFIGURE ID AND END-OF-LINE JUMPERS ON
COMLINK-2 CARDS
Each Comlink-2 card used to communicate parameters between PF-6
units and the main controller must have a unique identification number.
This number is configured using jumpers on the card and should be
assigned before plugging the card into each unit. To do this, use the
three jumpers (marked X100, X10 and X1) on the card (i.d. numbers can
go from 0 to 199). Use X1 for units, X10 for tens and X100 for hun-
dreds. In each case, place the black jumper horizontally over the two
pins corresponding to the digit required.
The PF-6 network operates on two communication lines. One line links
the PF-6 units together to the main controller and the other line links
temperature controllers to a computer (this second line is optional). Two
jumpers on the Comlink-2 card are used to identify the end of line for
each communication line. The PF-6 communication line uses jumper JP5
and the computer line uses JP4. Use pins 2 and 3 for YES and pins 1 and
2 for NO. The following diagram shows a typical connection with the
appropriate jumper configurations.
