Wiring Diagrams
Detailed electrical wiring schematics for the temperzone OPA 171RLTFYD unit, illustrating internal and client-side connections. The diagrams cover power distribution, control signals, fan motors, sensors, and communication interfaces.
Internal Wiring (Sheet 1 of 2)
This diagram shows the internal connections within the unit. Key components and connections include:
- Power Input: L1, L2, L3, N, PE (Protective Earth) connected via Main Isolator Switch (MIS), Control Circuit Breaker (CCB), Outdoor Fan Circuit Breaker (OFCB), Indoor Fan Circuit Breaker (IFCB), Variable Speed Drive Circuit Breaker (VSDCB).
- Controllers: UC8 Unit Controller and Carel c.pCO Mini Master Controller are central to the system.
- Fan Motors: Indoor Fan Motors (IFM1, IFM2) and Outdoor Fan Motors (OFM1, OFM2) are shown with their respective power and control connections, including Triac Fan Controllers (TFC).
- Sensors & Transducers: Various sensors are connected, including Discharge Temperature (DL), Suction Temperature (SL), Ambient Temperature (AMB), De-ice Temperature (DEI), Suction Pressure (LPT), and Discharge Pressure (HPT).
- Power Supply & Drives: Power supply (3-phase 400V AC) is distributed, with connections to the Power Speed Drive (PSD2) for motor control.
- Terminal Blocks: Numerous terminal blocks (TB1-TB28) are used for internal and external connections.
- Communication: Ethernet (ETH1-ETH10) ports are shown for communication.
- DIP Switches: Settings for UC8, PSD, and TFC are detailed in tables.
Client Wiring (Sheet 2 of 2)
This diagram details how external equipment and sensors connect to the unit. Key elements include:
- Client External Protection & Isolator Switch: Connection to the main power supply.
- Ethernet Port: For network communication.
- Carel cPCO - Mini High End Version Connections: Terminal blocks (TB1-TB28) are mapped to specific signals for sensors, actuators, and control inputs/outputs.
- Sensors: Connections for Room, Return Air (RA), Supply Air (SA), and Fresh Air (FA) temperature and humidity sensors. CO2 sensors and Drain sensors are also listed as optional.
- Actuators: Connections for dampers (DMRA, DMFA) are shown, including their control and feedback signals.
- Control Signals: Inputs for Unoccupied mode (UN-OCC), enable (ENB), fault (FAULT), and fan speed control (0-10V) are detailed.
- Communication Interfaces: RS-485 for Service Interface (J3) and other communication protocols (FBus, CAN) are indicated.
- Important Notes: Emphasize the need for a 24-hour power supply for control circuits and crankcase heaters. Also, notes on sensor connections for economiser functionality.
