ALARM CODE DESCRIPTIONS
6 — DIAGNOSTICS — TROUBLESHOOTING
6.1 — General
The PRO-DIALOG control system has many fault tracing aid
functions. The local interface and its various menus give access
to all unit operating conditions. The test function makes it
possible to run a quick test of all devices on the unit. If an
operating fault is detected, an alarm is activated and an alarm
code is stored in the Alarm menu.
6.2 — Displaying alarms
The alarm LEDs on the summary interface (see section 4.1)
give a quick display of the status of each circuit and the unit as
a whole.
—
A flashing LED shows that the circuit is operating but
there is an alarm.
—
A steady LED shows that the circuit has been shut down
due to a fault.
The Alarm menu on the main interface displays up to 5 fault
codes that are active on the unit.
6.3 — Resetting alarms
When the cause of the alarm has been corrected the alarm can
be reset, depending on the type, either automatically on return
to normal, or manually when action has been taken on the unit.
Alarms can be reset even if the unit is running.

This means that an alarm can be reset without stopping the
machine. In the event of a power supply interrupt, the unit
restarts automatically without the need for an external com-
mand. However, any faults active when the supply is inter-
rupted are saved and may in certain cases prevent a circuit or a
unit from restarting.
A manual reset must be run from the main interface using the
following procedure:
6.4 — Alarm codes
The following list gives a complete description of each alarm code and its possible cause.
Carrier is one of the oldest multinational corporations in the world, established in 1915 the company was one of the few that manufactured every single appliance part on its own. Building systems that lasted decades the company was solely focused on putting out appliances that make a name for themselves. Over the past decades, the company has gained a lot of achievements making them one of the few that have created a solid standing around the world.
Settled in more than 106 countries, Carrier is now available in six continents. Offering a wide range of appliances while keeping its main focus on its original air conditioning and heating system. These include air conditioning and heating solutions for residential and commercial buildings. One of the most promising appliances the company offers is its chillers which ensure smooth workings in various conditions.
When facing an error code we suggest you grab a pen and paper to note down the code rather than pressing various buttons on your Carrier Chiller. This way you will not risk damaging your appliance any further and will be able to find out the exact issue using the common error code list for Carrier Chiller error codes listed below. Once you nail down the issue you can easily call in a professional, or fix the issue yourself.

1 — SAFETY CONSIDERATIONS
1.1 — General
Installation, start-up and servicing of equipment can be hazardous if certain factors particular to the installation are not considered: operating pressures, presence of electrical components and voltages and the installation site (elevated plinths and built-up up structures). Only properly qualified installation engineers and highly qualified installers and technicians, fully trained for the product, are authorised to install and start-up the equipment safely. During all servicing operations all instructions and recommendations which appear in the installation and service instructions for the product, as well as on tags and labels fixed to the equipment and components and accompanying parts supplied separately, must be read, understood and followed.
•Apply all standard safety codes and practices.
•Wear safety glasses and gloves.
•Use the proper tools to move heavy objects. Move units carefully and set them down gently.
1.2 — Avoid electrocution
Only personnel qualified in accordance with IEC (International Electrotechnical Commission) recommendations may be permitted access to electrical components. It is particularly recommended that all sources of electricity to the unit be shut off before any work is begun. Shut off the main power supply at the main circuit breaker or isolator.
IMPORTANT: This equipment uses and emits electromagnetic signals. Tests have shown that the equipment conforms to all applicable codes with respect to electromagnetic compatibility.
RISK OF ELECTROCUTION: Even when the main circuit breaker or isolator is switched off, certain circuits may still be energised, since they may be connected to a separate power source.
RISK OF BURNS: Electrical currents cause components to get hot either temporarily or permanently. Handle power cable, electrical cables and conduits, terminal box covers and motor frames with great care.
Fanstart-up:
ATTENTION: In accordance with the operating conditions the fans can be cleaned periodically. A fan can start at any time, even if the unit has been shut down.
2 — GENERAL DESCRIPTION
2.1 — General
Pro-Dialog is a system for controlling single or dual-circuit 30RA/RY air-cooled liquid chillers or air-to-water 30RH/RYH heat pumps. Pro-Dialog controls compressor start-up needed to maintain the desired heat exchanger entering or leaving water temperature. In cooling mode it controls the operation of the fans to maintain the correct condensing pressure in each circuit. For heat pump units it controls and optimises the defrost cycles of each circuit in order to minimize the heating capacity reduction. Safety devices are constantly monitored by ProDialog to ensure their safe operation. Pro-Dialog also gives access to a Quick Test program covering all inputs and outputs.
All PRO-DIALOG controls can work in accordance with three independent modes:
•Local mode: the machine is controlled by commands from the user interface.
•Remote mode: the machine is controlled by remote contacts (volt-free contacts).
•CCN mode: the machine is controlled by commands from the Carrier Comfort Network (CCN). In this case, a data communication cable is used to connect the unit to the CCN communication bus.
The operating mode must be chosen with the Start/Stop button described in section 4.2.1. When the PRO-DIALOG system operates autonomously (Local or Remote mode) it retains all of its own control capabilities but does not offer any of the features of the CCN network.
2.2 — Abbreviations used
In this manual, the refrigeration circuits are called circuit A and circuit B. The compressors in circuit A are labelled A1, A2 and A3. Those in circuit B are B1, B2 and B3.
The following abbreviations are used frequently:

The control system consists of an NRCP-BASE board for single-circuit units and two NRCP-BASE boards (a master and a slave board) for dual-circuit units. Heat pump units equipped with optional additional heater stages use an additional board, type PD-AUX. All boards communicate via an internal SIO bus. The NRCP-BASE boards continuously manage the information received from the various pressure and temperature probes. The NRCP-BASE master board incorporates the program that controls the unit.
The user interface consists of two display blocks with up to 26 LEDs and 16 buttons (according to unit type). It is connected to the main basic board and gives access to a full array of control parameters.
3.2 — Electrical supply to boards
All boards, except the PD-RCPM board, are supplied from a common 24 V a.c. supply referred to earth.
CAUTION: Maintain the correct polarity when connecting the power supply to the boards, otherwise the boards may be damaged.
In the event of a power supply interrupt, the unit restarts automatically without the need for an external command. However, any faults active when the supply is interrupted are saved and may in certain cases prevent a circuit or unit from restarting.
3.3 — Light emitting diodes on boards
All boards continuously check and indicate the proper operation of their electronic circuits. A light emitting diode (LED) lights on each board when it is operating properly.
•The red LED flashing for a 2 second period on the NRCPBASE board indicates correct operation. A different rate indicates a board or a software failure.
•On dual-circuit units or units equipped with optional board, the green LED flashes continuously on all boards to show that the board is communicating correctly over its internal bus. If the LED is not flashing, this indicates a SIO bus wiring problem.
•The orange LED of the master board flashes during any communication via the CCN bus.
3.4 — The sensors
Pressure sensors
Two types of electronic sensors are used to measure the suction and discharge pressure in each circuit.
Thermistors
The evaporator water sensors are installed in the entering and leaving side. The outdoor temperature sensor is mounted below the control box. An optional water system temperature sensor can be used for master/slave assembly control (in the case of leaving water control).
In heat pump units a sensor placed on an air heat exchanger pipe ensures defrost operation.
5
3.5 — The controls
Evaporator pumps
The controller can regulate one or two evaporator pumps and takes care of automatic change-over between pumps.
Evaporator heater
It protects the evaporator (and the pipe heater for units without pump) against freezing if the unit is off.
Boiler
This relay output authorises start/stop of a boiler.
Condensate defrost heater
This heater is used for heat pump units and is located at the bottom of the air heat exchanger of each circuit. It prevents ice build-up, if defrost cycles are initiated at low outdoor temperatures.
3.6 — Connections at the user’s terminal block
3.6.1 — General description
The contacts below are available at the user’s terminal block on the NRCP-BASE board (see figure 1). Some of them can only be used if the unit operates in remote operating type (rEM).
