Installation

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 specific 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):
