LAN TRANSIENT INSTALLATION
The properly installed Lan Transient Protection Module,
(part number 031-01586-000) will limit the voltage
levels seen by the chiller control panel’s RS-485 driver
while allowing normal RS-485 network operation under
non-transient conditions. For installation of the module
refer to Fig. 2 and the specic installation instructions
for the microboard.
Unit Microboard 031-01314-000 and
031-02050-001:
Step 1: Label all wires, cables, or components con-
nected to TB1.
Step 2: Carefully loosen each terminal of TB1. Remove
all wires, cables, or components. Be extremely careful
to not allow them to short together or to the enclosure.
Step 3: Refer to the Module. Replace all wires,
cables, or components taken from TB1 into the cor-
rect terminals of the Module terminal strip J1 being
extremely careful to not allow them to short together
or to the enclosure.
Step 4: Carefully tighten all screws on the Module
Terminal strip J1.
Step 5: Orient the Module as shown (component side
down) and cut the unused pins. Insert the four P1
Module pins into TB1 as shown.
Step 6: Carefully tighten each terminal of TB1. Double
check all wiring to the Module before closing up.
Unit Microboard 031-01095-000:
Step 1: Label all wires, cables, or components con-
nected to TB7.
Step 2: Carefully loosen each terminal of TB7. Remove
all wires, cables, or components. Be extremely careful
to not allow them to short together or to the enclosure.
Step 3: Replace all wires, cables, or components taken
from TB7 into the Module terminal strip J1 being
extremely careful to not allow them to short together
or to the enclosure.
Step 4: Carefully tighten all screws on the Module
Terminal strip J1.
Step 5: Orient the Module as shown (component side
up) and insert all six P1 Module pins into TB7 as
shown.
Step 6: Carefully tighten each terminal of TB7. Double
check all wiring to the Module before closing up.
EPROM COMPATIBILITY
Since the concept and design of the OptiView Remote
Control Center may have occurred after the original
EPROM (software) for the chiller/condenser control
panel, the EPROM may need to be replaced with
one that allows for OptiView Remote Control Center
operation. See Table 1.
TROUBLESHOOTING
From the Home Screen you can determine if you are
communicating to the chiller/condensing unit.
If the message Not Initialized.. remains shown on this
screen, proper communication between the panels has
not occurred and you will need to troubleshoot.
Step 1: If you are trying to communicate with more
than one unit, simplify the troubleshooting by isolating
the communication to one unit at a time. Remove any
wiring to a secondary unit and from the Setpoints
Screen of the OptiView RCC, enter one as the Number
of Units Connected and at the chiller/condenser control
panel set it’s ID to zero.
Step 2: Check if there is any communication problem
occurring on the Diagnostic RCC Comms Screen. See
the description of this screen.
You could also check that the RX3 I/O communication
activity LED on the OptiView Main Processor Board is
blinking as it receives data from the chiller/condensing
unit’s control panel. A steady lit RX3 LED is a sign of
improper wiring. If the RX3 LED is not blinking check
the wiring and the installation of the Lan Transient
Protection Module. If everything is properly connected
replace the 485 driver on the chiller/condenser
microboard (part number 031-02074-000).
SAFETY
It is recommended that all maintenance and service
repair work be performed by experienced personnel.
There must be recognition of the potential hazards
that can exist. Those hazards may include (but are
not limited to):
