Install Quad Relay Output LLID—CH530 If
Using Chiller Control Sequence 1
Notes:
• If the DynaView had CTV software and was using control
sequence 1, then installing the quad relay output LLID is
required. To determine this, examine the chiller service
report that was saved earlier. In the configuration section,
look for Connected to and in the CH530 section, look for
Control Sequence. If these items are CTV and 1,
respectively, then adding the quad relay output LLID is
required. If not, then skip this procedure.
• If the quad relay output LLID is added, it also needs to be
bound in the programming phase of the Symbio™ 800.
1. Remove LLIDs 1A3 dual relay, 1A5 dual relay, and 1A10
dual relay output from the control panel. Refer to Figure 67,
p. 34.
2. Install the quad relay output LLID in an open space in the
control panel, as close as possible to where the 1A3 LLID
was formerly located.
Note: This may also require moving some of the other
LLIDs to different control panel locations.
3. Connect the wires from the previously removed LLIDs to
the quad relay output LLID terminals as shown in
Figure 67, p. 34.
Install Communication Cable Between 1A1
and 1A2 Power Supplies
Note: Proceed directly to the installation section “Routing
New Wire Into and Out of the Control Panel Enclosure,”
p. 18, if the 1A2 power supply was already in place as
part of the previous CH530 control system.
1. Connect the power supplies together at the J1 terminals
using the 2-conductor power supply communication cable
provided.
Note: If the J1 terminals are already being used, the
communication cable can instead be connected to
the J11 terminals on both power supplies.
Notes:
• Bk - Black wire
• R - Red wire
