Electronic control panel 30PA
The 30PA control is basically comprised of a µPC SMAL control board, a pGD1 graphic terminal, a TCO user terminal (optional for remote control) and sensors.
Main functions:
- Selection of inlet water temperature set-points
- Permanent control and optimization of the operating parameters
- Safety management
- Timing of the compressor
- Regulation of the water outlet temperature
- Timer and weekly programming
- Failure diagnosis and main alarm
pGD1 terminal
This graphic terminal, installed on the electric panel of the machine, allows :
- The initial programming of the unit
- Modification of operating mode
- Unit ON / OFF
- Selection of the operating mode
- Setting of set-points
- On-screen display of controlled variables and sensor values measured
- On screen display of active alarms and historical records of alarms
TCO user terminal (optional for remote control)
The TCO user terminal, for remote control, allows:
- Modification of some operating parameters
- Unit ON / OFF
- Selection of the operating mode and setting of set-points
- On-screen display some controlled variables and probe values
- On-screen display of alarms codes
Configuration
- Vertical air supply, M01 assembly (default horizontal supply, M00 assembly)
- In the STD version : different configurations of available pressure from 7 to 35 mm.w.c. configuration
- Vertical air supply, M01 assembly (default horizontal supply, M00 assembly)
- In the STD version : different configurations of available pressure from 7 to 35 mm.w.c.
Climatic conditions
- In units with the STD version that work in cooling with an outdoor temperature lower than 12°C, the condensation pressure control allowing an "all seasons" operation (up to -15°C) is mandatory. This is performed per motorized damper in the fan outlet.
- Coils protection :
- Coil with copper pipes and copper fins (upon request)
- Coil with copper pipes and aluminum fins with polyurethane and blygold coating
- During periods with low outdoor temperatures, anti-freeze protection for the unit :
- Electrical heaters in the condensate drain pan. Mandatory when outdoor temperatures are below 3°C
- Operation with glycol water up to a minimum outlet temperature of -7°C
- Anti-freeze protection with flexible electrical heaters around the pipe of the hydraulic circuit
Installation
- Antivibration mounts made of rubber
- Protection grille for the coil
- Gravimetric filters in the return air. The filters frame is removable, and upon request, it is possible to supply the frame independently with the unit, to be joined on site
- Flexible ducts for supply and return air
- Flexible hydraulic connections (500mm), supplied in the kit
Available for:
- Inlet / outlet of the unit
- Inlet / outlet of the desuperheater circuit
- For 30PA units, filter with stainless steel mesh (500 microns), supplied in the kit
- Cut-off and water control valves, supplied in the kit
- High-pressure and low-pressure gauges in the cooling circuit
Energy recovery
Desuperheater circuit which includes :
- Thermally isolated, welded stainless steel plate exchanger for working in a closed circuit in the recovery of hot gases
- Draining valve and ball valve
- Hot water recovery control thermostat
- Option for a 3-speed hot water circulation pump
Electric panel
- Compressor soft starter
- Transformer for power supply without neutral
- Voltage 400 / 440V - 60 Hz (Upon request)
- Energy meter for monitoring of the power consumption of the installation
Control / communications management
- TCO user terminal, for remote control
- RS485 serial cards for network communication with protocols : Carel, Modbus, LonWorks®, BACnetTM MSTP, Konnex
- Ethernet pCO Web card for network communication with protocols : Modbus TCP/IP, BACnetTM Ethernet, TCP/IP, SNMP V1-2-3, FTP and HTTP
