The character in the 4 digit descriptor define the number of
fans that are intended to be wired to each of the 4 relays on
the respective circuit’s quad fan control relay LLID.The
first of the two possible 5 fan arrangements uses sequence
1 H 1 3.This sequence implies there should be 1 fan wired
to relay 1 (terminals J2-1,3 of module 1A25 – Circuit 1 Fan
Control module, which are internally wired to the 1X11
terminals 1 & 2).Then next digit in the sequence H, is only
for use with the High speed of a 2 speed fan configuration
and since “none” was selected for low ambient options,
this means it is not to be used and nothing should be wired
to the 2nd relay (terminals J2-4,6 1X11 terminals3&4).
Likewise, the 3rd and 4th digits imply the number of fans
that are to be wired to the 3rd and 4th relays, (the relays
being internally wired to the terminal strip 1X11 terminals
5&6and7&8respectively.)
The second alternative wiring for a fixed speed 5 fan deck
is the 1112 selection. In this scheme, the first 3 relays
(terminals 1X11 1&2, 3&4, 5&6), should all be wired to
control one fan, and the last relay should control 2 fans
(1X11 terminals7&8)
Repeat the same selection for circuit 2 by click on the Fan
Deck Arrangement Circuit 2 item. In the drop down box,
you will see a number of supported fan deck
arrangements. Select the appropriate fan deck
arrangement for circuit 2.The selection of the
arrangement would then define the wiring for module
1A26 – Circuit 2 Fan Control Module and it associated field
wiring terminals 1X11 terminals 9 &10, 11 & 12, 13 &14, and
15&16).
Note: The fan deck arrangement does not necessarily
have to be the same as Circuit 1, but usually the
circuits have the same number of fans and
therefore the same arrangement selection is
appropriate.
As a last important step, the configurations need to be
downloaded to the CH530 DynaView/Main Processor.This
is accomplished by clicking on the “Load Configurations”
button at the bottom of the configurations screen.
Allow a short time for the configuration to be set and both
the CH530 DynaView andTechView to reboot. If new LLIDs
and hardware binding for them is required as a result of
the configuration just downloaded,TechView will
immediately launch the “Binding View” that provides for
a list of the required LLIDs and their communication
status. Install and bind all new LLIDs as required. Most
often, however, the proper LLIDs will already be present
and bound if the options were appropriately ordered with
the chiller.
