CONTROL OPERATION
This section identifies important control functions such as unit start and stop, cooling control, and more. It also describes how to perform key operations of the control system.
Start/Stop Control
Table C summarizes the unit control type and stop or go status with regard to the following parameters.
· Operating type: this is selected using the start/stop button on the front of the user interface.
LOFF Local off
L-C Local on
L-SC Local schedule
REM Remote
CCN CCN Network
· Remote start/stop contacts: these contacts are used when the unit is in remote operating type (Remote).
· CHIL_S_S: this network command relates to the unit start/stop when the unit is in network mode.
· Start/Stop schedule: occupied or unoccupied status of the unit as determined by the unit start/stop program (Schedule 1).
· Network emergency shutdown: if this CCN or BACnet/IP (option) command is activated, it shuts the unit down whatever the active operating type.

· CCN emergency shutdown: if this CCN command is activated, it shuts the unit down whatever the active operating type.
· General alarm: the unit is totally stopped due to failure.
Unit Stop Function
This function controls the unit compressor capacity reduction. If there is an alarm or a demand to stop it forces the compressors to the minimum capacity before stopping them.
This stop sequence is not followed if there is a unit protection alarm such as “water heat exchanger frost protection” or “low saturated suction temperature”.
Evaporator Water Pump Control
The unit can control the evaporator water pump. The pump is turned on when this option is configured (see PUMPCONF configuration sub-menu) and when the unit is in one of the on modes described above or in delay mode. Since the minimum value for the delay at start-up is 1 minute (configurable between 1 and 15 minutes), the pump will run for at least one minute before the first compressor starts.
The pump is kept running for 20 seconds after the unit goes to stop mode. It is turned off if the unit is shut down due to an alarm, unless the fault is a frost protection fault.
The control provides a means to automatically start the pump each day at 14.00 for 2 seconds when the unit is off. Starting the pump periodically for a few seconds increases the lifetime of the pump bearings and the tightness of the pump seal.

Condenser Water Pump Control

ACTIVE SETPOINT

Control of the condenser water pump is the same as for the evaporator water pump. See “Evaporator Water Pump Control” on page 32. There is only one condenser pump.
Control Point
The control point represents the water temperature that the unit must satisfy.
In cooling mode the evaporator outlet water is controlled by default, but the evaporator inlet water can also be controlled (requires a Service configuration modification).
In heating mode the condenser outlet water is controlled by default, but the condenser inlet water can also be controlled (requires a Service configuration modification).
Control point = active setpoint + reset.

Two setpoints can be selected. Usually, the second cooling setpoint is used for unoccupied periods. Depending on the current operation type, the active setpoint can be selected by choosing the item in the table Status Genunit, with the volt-free user contacts, with network commands or with the setpoint timer program (schedule 2).
Table D summarizes the possible selections depending on the control types (local, remote or network) and the following parameters:
· Setpoint select in local control: item “Setpoint select” in the table Status Genunit permits selection of the active setpoint, if the unit is in local operating type.
· Control contacts 2: status of control contact 2.
· Schedule 2 status: schedule for setpoint selection.

RESET
Reset means the active setpoint is modified so that less machine capacity is required (in cooling mode the setpoint is increased, in heating mode it is decreased). This modification is in general a reaction to a drop in the load. For the Carrier Controller control system, the reset source can be configured in the menu Status RESETCFG: it can be based on the outdoor temperature (gives a measure of the load trends for the building) or used with the energy management option at the reset setpoint. In response to a drop in the space temperature or to a drop in T, the cooling setpoint is normally reset upwards to optimize unit performance.

In the three cases the reset parameters, i.e. slope, source and maximum value, are configurable in the Setpoint menu.
Reset is a linear function based on three parameters:
· A reference at which reset is zero (space temperature or T – no reset value).
· A reference at which reset is maximum (space temperature or T – full reset value).
· The maximum reset value.
See Fig. Y.

APPENDIX A — CARRIER CONTROLLER SYSTEM MENU STRUCTURE (CONT)

Demand Limit
Generally, demand limit is used by an energy management system in order to restrict the unit electricity consumption.
The PIC6 control system for 30HX provides two methods of demand limit:
· By reference to a limiting signal from a user-controlled volt-free contact: the capacity of the unit cannot exceed the demand limit setpoint (which can be modified in the Setpoints menu) when the limit contact is closed.
· By reference to an external 0-10 vdc signal: the capacity of the unit cannot exceed the demand limit imposed by this external signal. It is a linear function and its parameters are configurable in the User1 menu (voltages at 0% limitation and 100% of limitation). This function is not available if Reset by reference to an external 0-10 vdc signal has already been selected.
Whatever the method used, demand limit is active in all operating types: Local, Remote or CCN. However, in Local operating type, demand limit can be disabled and in CCN operating type, demand limit can be controlled directly with the aid of CCN commands.
NOTE: A limitation value of 100% means that the unit may call upon the full array of its capacity stages.
Figure Z is an example of demand limit by an external 0-10 vdc signal. This example assumes that the limitation parameters are such that at 0 volt the authorized capacity shall be maximum capacity, and at 10 volts the authorized capacity shall be zero (this is the default configuration).
Capacity Control
This function adjusts the compressor capacity to keep the heat exchanger water temperature at its setpoint. The control system

continuously takes account of the temperature error with respect to the setpoint, as well as the rate of change in this error and the difference between entering and leaving water temperatures, in order to determine the optimum moment at which to add or withdraw capacity.
In addition, the high pressure or low pressure unloading functions can also affect the temperature control accuracy.
Compressors are started in a sequence designed to equalize the number of start-ups (value weighted by their operating time).
Saturated Condensing Temperature Control
Saturated condensing temperature control is assured if the threeway valve option is selected. The saturated condensing temperature is controlled based on a fixed setpoint that can be configured by via the SETPOINT table. The three-way valve control can be configured by the service department via the SERVICE table.
Determining the Lead Circuit
This function commands the start/stop sequence of the two refrigerant circuits called A and B. The circuit authorized to start first is the lead circuit. Three methods can be configured by the user in the Configuration menu:
· Auto mode: the control system determines the lead circuit so as to equalize the number of starts on each circuit (value weighted by the operating times of each circuit). Thus, the circuit with the least number of starts is always given precedence to start. The lead circuit is stopped last.
· Circuit A as leader: Circuit A is always the lead circuit. It is the first to start and the last to stop.
· Circuit B as leader: Circuit B is always the lead circuit. It is the first to start and the last to stop.

APPENDIX A — CARRIER CONTROLLER SYSTEM MENU STRUCTURE (CONT)

Circuit Loading Sequence

High Current Load Shedding Function

Two circuit loading sequences are available. The choice of sequence can be configured by the user in the Configuration menu
· Balanced circuit loading: If this sequence is selected, the control system tries to keep the capacity of circuits A and B equal as the total load on the unit increases or decreases.
· Loading with priority given to one circuit: If this sequence is selected, the control system loads the lead circuit completely before the second circuit starts up. When there is a demand limit, the second circuit is unloaded first.
IMPORTANT: 30HX units use 06N twin screw compressors. The screw compressor efficiency is better at full load than at part load. By default, the ‘close control’* configuration is not validated, and the control will always try to optimize unit efficiency.

• Temperature precision has priority over compressor capacity. This parameter is only accessible to Carrier Service.
  Compressor Start-Up Sequence in One Circuit
  The first compressor to start is the one with the least number of start-ups and operating hours. If both compressors are operating and the load decreases, the compressor that started first shuts down. This avoids cycling of the same compressor.
  EXV Control
  The electronic expansion valves (EXVs) control charging and the refrigerant flow in the evaporator, maintaining the optimum evaporator throttle and a correct discharge superheat. Opening the valve permits reduction of the throttle, and thus improves the heat exchange in the evaporator. This opening can be limited to maintain the condenser subcooling and correct superheat, avoiding liquid slugging at the compressors and ensuring operating stability.
  Motor Cooling Valve Control
  The temperature of the motor windings is controlled to a setpoint of 82°C. This is achieved by cycling of the motor cooling valves to allow the liquid refrigerant to flow across the motor windings, if necessary. On units equipped with economizers with plate heat exchangers, a thermostatic valve controls the necessary refrigerant flow entering this heat exchanger and continuously flowing over the motor windings. All refrigerant used for motor cooling returns to the rotors through an orifice situated mid-way along the compression cycle and is compressed to the discharge pressure.
  Head Pressure Control on Water-Cooled Units
  The saturated condensing temperature is controlled by reference to a user- definable fixed setpoint.
  This temperature is maintained by using the valve to control the flow of water in each condenser circuit.
  High Pressure Load Shedding Function
  This function does not require an additional board. It prevents high pressure breaks on a circuit by the following means:
  · Preventing any capacity increase on the circuit once the high-pressure value has reached an initial threshold.
  · Shedding one or more capacity stages once a second protection threshold has been reached.
  In the event of capacity stages being shed, no capacity increase will be authorized on the circuit for a period of 5 minutes.
  NOTE: The last capacity stage cannot be shed by this protection function. An alarm is activated if the high pressure is still too high.

This function does not require an additional board. It prevents high current breaks on each compressor by the following means:
· Preventing any capacity increase on the compressor once the high current value has reached an initial threshold
· Shedding one or more capacity stages once a second protection threshold has been reached.
In the event of capacity stages being shed, no capacity increase will be authorized on the circuit for a period of 5 minutes.
Start-up Procedure — Prelubrication
This procedure describes the necessary procedures to ensure the lubrication of the compressor before start-up.
The control follows the sequence below:
For the lead compressor (the first compressor in the circuit to start):
1. Start the oil pump and measure the initial oil pressure.
2. Wait approximately 30 seconds.
3. Verify the oil solenoid valve tightness. – If oil pressure increases and the solenoid valve is not open, the oil solenoid valve failure alarm is activated and prelubrication is stopped. The procedure is aborted. – If not, the oil solenoid valve is activated.
4. Wait approximately 15 seconds.
5. If oil pressure increases, prelubrication is assured and the compressor can start.
6. If not, a further prelubrication cycle is started. Return to point 1.
NOTE: After three cycles, the low oil pressure alarm at pre-startup is activated, and prelubrication is also stopped.
For the lag compressor (one compressor in the circuit is already in operation).
1. Activate the oil solenoid valve.
2. Wait approximately 15 seconds.
3. If oil pressure increases, prelubrication is assured and the compressor can now start.
4. If not, the low oil pressure at start-up alarm is activated and the prelubrication is also stopped.
Time Schedule Function
The control includes two-time schedules.
The first schedule (schedule 1 OCCPC01S) allows automatic changeover of the unit from occupied to unoccupied mode: the unit is started during occupied periods.
The second schedule (schedule 2 OCCPC02S) allows automatic change of the active setpoint (if auto mode is selected) from the occupied setpoint to the unoccupied setpoint.
Cooling or heating setpoint 1 is active during occupied periods. Cooling or heating setpoint 2 is active during unoccupied periods.
Each time schedule consists of eight user configurable periods. Each of these periods can be validated as active or not active for each day of the week as well as for holiday periods. The day begins at 00:00 and ends at 23:59.
The schedule is in unoccupied mode unless a time period is active. If two periods coincide or are active on the same day, priority is given to the unoccupied period. Each of the eight periods can be displayed and modified using a sub-menu.The following table shows how to configure a period. The method is the same for time schedule 1 and 2.

HOLIDAYS MENU

This function is used to define 16 holiday periods. Each period is defined by three parameters: month, start day and holiday period duration. During the holiday periods the controller is in occupied or unoccupied mode, depending on the periods validated as holidays. Each of these holiday periods can be displayed or modified using a sub-menu.

IMPORTANT: The Broadcast function must be active for the holiday function to operate, even if the unit is in autonomous mode (not connected to the CCN network).

Black Box Function
The Carrier Controller registers the values of around 20 predefined variables every 5 seconds. If an operation alarm appears, the control saves a data set of 180 registrations (168 preceding the alarm and 12 following it), for a duration of 15 minutes of unit operation.
Each registration is associated with a time schedule defined in hours, minutes and seconds. The control can store a maximum of 20 data sets in the memory. If the threshold of 20 data sets is reached, a rotary registration mechanism is triggered (a new data set deletes the oldest data set). The data sets can be recovered by a Carrier service technician, using the Carrier Pro-View tool that permits downloading them to a PC and later deleting them from the unit.

Energy Management Option

This option requires the installation of an additional SIOB-BASE EMM type board. This board permits access to the following functions:

· Reset via 4-20 mA control.

· Ice storage contact: if ice storage control has been config-
ured (Configuration Menu General Configuration), this contact permits activation of the ice storage setpoint.

· User safety loop input: this contact is used for the customer safety loops that require a unit shut-down if it is closed.

· Occupancy control time schedule override contact: if this contact is closed, the unit enters the occupied mode for a configurable override time of 1 to 4 hours.

· Condenser water flow input.

· Demand limit setpoint contact and output.

This option also permits display of the following data:

· Current unit capacity via 0-10 vdc output

The Carrier Controller has many fault tracing aid functions. The local interface and its various menus give access to all unit operating conditions. If an operating fault is detected, an alarm is activated and an alarm code is stored in the Alarms menu, sub-menus “Reset alarms” and “Current alarm”.
Email Notification
The control system can define one or two recipients and notify the recipient by email whenever a new alarm occurs or resets all currently existing alarms. NOTE: Email notifications can only be set by a Carrier service technician.
Alarm Display
The control system quickly displays the status of the unit (Fig. AA). Once the alarm is activated, the icon clock on the touch screen lights up and shakes. · The LED flashes and shakes to indicate that the loop
is running, but there is a warning. · The indicator light is steady red and shakes to indi-
cate that the circuit has stopped due to a malfunction.

Resetting Alarms
When the cause of the alarm has been corrected, the alarm can be reset either automatically on return to normal, or manually when action has been taken on the unit, depending on the type. Alarms can be reset even if the unit is running, service login is required.
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 command. However, any faults active when the supply is interrupted are saved and may in certain cases prevent a circuit or a unit from restarting.
