Manual CORRIGO L10 2002-11

CORRIGO L10 for use with air handling systems comes with or without LON

communication option.

L10 Temperature controller for up to three sequences

L10-LON Same as L10 bus also has LON Works communication.

Introduction

COORIGO L10 is a new controller which has been designed to be easy to use and

operate. It has been designed for use in less complex air-handling systems. The

controller has a display and built in indicator on the front for alarm and is operated

by means of clearly defined buttons.

The controller has been designed for mounting on a DIN rail, in norm housing or on

the front of a cabinet.

The required functions are selected with the help of questions in normal script or by

means of a code under the configuration menu depending on the type of application.

The controller has a year-base clock and automatic summer/winter time changeover.

The menu system works with different user-levels to show settings and to allow

settings to be altered. This means that non-technical staff can feel secure while

using the system since it is impossible, on the lower user-levels, to programme

incorrect settings when checking operating status, parameter values, alarms etc.

During normal operation, without pressing any buttons, the display also shows the

most important operating statuses such as setpoint/current value, sequence-output

control and time/date/version etc.

We hope you will be satisfied with your CORRIGO and that it will provide you with

simpler and more economic running of your control systems.

Installation

Corrigo L10 can be mounted on a DIN-rail in a panel or in a panel front.

Panel front assembly kit (See page 2)

When CORRIGO L10 is mounted in a panel front the procedure is made easier by

using the assembly kit FMC. This kit includes front frame in aluminium, support rail,

nuts and bolts. Reversable screw terminals can be ordered (article id: PLTL).

Alternatively FMK1 front mounting kit can be used. It has a transparent cover and

meets the IP54 protection class.

If two CORRIGO L10 are placed adjacent to each other, use the FMCR assembly kit

which is wider. It essentially contains the same things as the FMC kit. Alternatively,

use the FMK2 front mounting kit (has the same properties as FMK1, only wider).

Supply voltage

The L10 is supplied with 24 V AC.

Inputs

The analogue sensor inputs (AI1-4) have a common reference point that is signal

ground. The digital inputs (DI1 - 4) have a common reference point that is not the

same signal as neutral (terminal 19) and must therefore not be tied together.

The signal neutral for analogue inputs and analogue outputs and the system neutral

(terminal 25) are internally connected.

Outputs

Analogue outputs (0...10V) have signal neutral as common reference point, terminal

23. Digital outputs are divided into two categories: Outputs DO1 and DO2 are of triac

type and have a common 24 V AC feed point at terminal 8. Outputs DO3...DO5 are of

relay type and have a common pole at terminal 11.

Wiring

Connects sensors using a shielded twisted-pair wire. The shield should be connected

to the earthrail in the cabinet and left unconnected at the sensor end.

Digital inputs DI

CORRIGO L10 has 4 digital inputs, DI1...DI4 in order to to activate certain functions

and to monitor alarms.

These inputs must only be connected to potential free closing switches.

These inputs should only be closed against the common point DI+ on terminal 7.

Terminal 7 is NOT signal neutral; do not wire together.

DI1 Fan malfunction alarm or Fan status indicator.

- Fan alarm: Intended for use with, for example an overcurrent protection

device. Activates the fan alarm after 2 seconds and stops the system.

- Fan status: Connect to a pressure switch or free contact in the fan motor

relay. In order to activate the controlling outputs on the L10, the DI1

input must be activated within preset delay time. If this does not occur the

system stops and alarm is activated. To check status for more than one fan,

connect the status circuit breakers in series to DI1.

DI2 Water heater pump status.

Must be connected when water heater is used.

Stopped pump interlocks the system.

DI3 Input for status monitoring or alarms. Following functions can be set:

- Extended runtime using timer or pushbutton. Can also be used with presence

detectors.

- Alarm from smoke detectors

- External alarms

DI4 Input for various alarms. Following alarm types can be set:

- Cooler alarm

- Heat exchanger alarm

- Smoke alarm

- External alarm

AI Analogue inputs

CORRIGO L10 has 4 analogue inputs, AI1...AI4.

These inputs are for use with temperature sensors of type Pt1000.

Exception: The AI4 input is used as a digital input when the unit is configured with

overheat protection on an electric heater. In that case, connect this input to a poten-

tial free closing contact.

Wire AI-inputs with sensor between respective input and common signal neutral

(terminal 19).

AI1 Outdoor sensor

For example, type TG-R6/Pt1000.

AI2 Room sensor

For example, Ex type TG-R5/Pt1000.

AI3 Supply air sensor

For example, type TG-KH1/Pt1000.

AI4 Frost protection sensor when used with water heater, for example,

type TG-A1/Pt1000 or

overheat protection thermostat when used with electric heater.

Connect this input to a potential free closing switch if configured as overheat

protection input.

Wiring

Manual CORRIGO L10 2002-11

Digital outputs DO

Corrigo has 5 digital outputs DO1...DO5.

Outputs DO3...DO5 are potential free closing relay contacts, 230V AC, 5A.

Outputs DO1...DO2 are of triac type for use with 24 V AC, 0.5A (1A short duration).

The triac outputs have a common 24V supply pole (see picture in margin).

For use with higher voltages and currents, use external relays.

DO1 Control DX-Cooling stage 1

DO2 Control DX-Cooling stage 2 or external fan control interlock for frost protection.

When used in systems with external fan control and frost protection it is

advisable to interlock fans over this output to ensure that the fans are stopped

in the event of a frost alarm.

DO3 Control fans

DO4 Control pump or electric heater interlock

When the system is configured with electric heater, DO4 is used to interlock

the heater. For example: when a steprelay is used for heating control the heat

will be activated during the cool-off sequence. To prevent this, interlock the

heater via this output (DO4) to ensure that the heater is disconnected from

power during the cool-off period.

When using electric heater the DO4 output is active, except when the system

is idle and during the cool-off period.

DO5 Alarm output.

Analogue outputs AO

CORRIGO L10 has 3 analogue outputs, AO1...AO3.

Outpul levels are 0...10 V DC, 5 mA. Short circuit protected.

Reference point is terminal 23, signal neutral which is internally connected to

terminal 25, system neutral.

The outputs AO1...AO3 make up the temperature controlling sequence. Function for

each output is determined by configuration setting but the order is always

Y3 ? Y2 ? Y1 on increasing heat demand.

AO1 Y1 - Heating or cooling

AO2 Y2 - Cooling, damper, Plate exchanger or rotating exchanger

AO3 Y3 - Cooling

Configuration

CORRIGO-L10 is adapted to the system at hand by selecting functions individually. All

configuration options are set using explanatory menu texts.

Configuration codes

There is also the option of setting parameters by means of two configuration codes.

This function is particularly useful and timesaving when a number of controllers are to

be configured in the same way.

The first thing to be shown when the configuration menu is opened is the setting of

the control function. Using the arrow up button the configuration code will be dis-

played, and the arrow down button will give the parameters of the other configurations

in plain text.

The code digits in the configuration code correspond to the script parameters below

in numerical sequence. This means that the first digit in CONFIG CODE determines

which control function the controller is to work with. The second digit refers to

sequence etc.

In front of the corresponding selection in the script parameters there is a digit which

corresponds to the code number in the configuration code. See the details below.

Guide for configuration code

There is also a special table to facilitate the choice of configuration code. This is

always supplied together with the CORRIGO L10 instruction sheet.

In the table all the configuration parameters are shown as well as the selections that

can be made. Basic selections are marked in bold type.

By going through the parameters and filling in the appropriate figure for each

selection the configuration code can be obtained without difficulty. This can also act

as a protocol of settings for CORRIGO L10.

Automatic restart after changing

When one or more parameters have been changed the controller will restart when the

user leaves the configuration menu.

Room temperature control with cascade control of the supply air temperature

The temperature sensor Supply air (AI3) controls the sequence so that the setpoint

is reached in the same way as with supply air control. The setpoint for the supply air

temperature is determined by Room sensor (AI2) which, when heating is required,

raises the setpoint for supply air according to the parameters set or, when cooling is

required, lowers the setpoint.

The cascade factor (by how much the setpoint should be changed on a one-degree

deviation from the set room-temperature) is set under ”Settings”, see the appropriate

section.

NOTE: Cascade control is a PI-control with settable I-time (Factory setting 10 minu-

tes) and works with setpoints between set minimum and maximum limitation.

(Current setpoint for supply air temperature is shown in the menu for cascade factor).

is always activated first, then Y2

and finally Y1.

Configuration

Manual CORRIGO L10 2002-11

Controlling plate heat exchanger

Plate heat exchanger means that the output controls e.g. a damper actuator

to vary the capacity of the heat exchanger.

Defrosting plate heat exchanger

Ice-build up sensor (pressure switch) is connected to DI4. On ice build-up the

defrosting function is activated.

The heat exchanger capacity is set to zero and the heating sequence, Y1 is

used when heating is required. If this is not sufficient to maintain the setpoint

the heat exchanger is permitted to go in with up to 30% of capacity.

The fans continue to operate.

Defrosting will continue until the ice build-up sensor returns to normal, with a

switch-off delay of 10 minutes.

Controlling rotating heat exchanger

Alarm from a rotation sentinel can be connected to input DI4.

CORRIGO L10 can be set to stop the fans on rotation sentinel alarm.

Set under ”Settings”.

D. Frostprotection

0. No

1. Y1

2. Y1 Automatic reset (Reset is performed when the temperature rises to

alarm point plus 5K, with a time delay of

10 minutes)

The alarm limit for the frost protection sentinel is set under ”Settings”.

(Factory setting is 7°C.) The system begins to override the output signal to

the valve when the temperature is 5K higher than the alarm limit. This means

that the temperature when the output begins to be affected is 12°C for the

factory alarm setting of 7°C.

E. Shutdown mode

Controls the heating valve to maintain a preset temperature at the frost

protection sensor when the system is shut down.

Shutdown temperature is set under ”Settings”. (Factory setting, 25°C).

This function is only activated when the pump output (DO3) is active. It means

that when the pumpstop function has been selected, as described in the

paragraph below, the shutdown mode will be deactivated when the pump is

stopped due to warm weather.

0. No

1. Yes

F. Pumpstop

This function requires an outdoor temperature sensor. The circulation pump is

stopped when there is no heating demand (Y1 is less than 1%) and the

outdoor temperature is above a preset temperature. The basic setting is +6°C.

Stop delayed 15 minutes. Can be set under settings. Stopped pump is

exercised 5 minutes every day at 12:00.

G. Function AI1

Normally AI1 is used as input for outdoor temperature sensor. If external set-

point is desired, change setting and connect a setpoint adjust unit to AI1.

When set to external setpoint, no other functions requiring outdoor temperature

sensing can be used.

0. Not active

2. External setpoint

H. Function DI1

Connect DI1 to thermal or overload guard(s), or, status indicator(s) circuit

breakers located on relays or similar.

Fan alarm: Use this setting when connecting this input to a filter guard or

similar. Activates fan alarm after preset time delay (2 seconds).

Fan status indicator: In order to start the control sequence and activate

the analogue outputs DI1 has to be closed. When the fan control output (DO3)

is activated, Corrigo L10 awaits a status running signal at DI1. If no status

running signal is present at DI1 after a preset delay time, a fan alarm is

activated and the system stops.

Configuration

K. Function DO1/DO2

When DX cooling is selected, at least one of the outputs Y2 or Y3 must be

configured as cooling control output.

In applications with supply air minimum limiting the minimum limit will be

lowered by a preset amount when the DX-cooling is activated. See under

”Settings”.

DX Binary means that the two outputs are controlled in a binary

sequence: 1, 2, 1+2.

If an outdoor sensor has been configured on AI1, DX-cooling will be blocked

for outdoor temperatures lower than +12°C (fixed value).

When an external fan control switch is used in systems with frost protection,

it is recommended that this breaker is routed via this interlock output. This is

to prevent forced (manual) fan run when the frost alarm is activated.

Inputs

This menu is used to inspect current values/states for the AI and DI inputs.

AI1 Outdoor temperature or external setpoint

AI2 Room temperature

AI3 Supply air temperature

AI4 Frost protection sensor When frostprotection is selected with water heater

or Overheat protection When electric heater is used

DI1 Fan malfunction or fan status indicator.

DI2 Pump status or electric heater interlock

DI3 Input for extended runtime, smoke detector alarm or external alarm

DI4 Input for alarm from chiller/cooler, exchanger, smoke detector alarm or external

Adjustment of analogue inputs

The analogue inputs are intended for use with Pt1000 type sensors.

You can also inspect min and max values since last value reset. Refer to menu

branch ”Settings”.

The presented value for inputs AI1...AI4 can be trimmed by ± 2 K when needed.

Make a login at level 3, enter the appropriate input menu for AI1...AI4, press the ?

key and adjust the readout with the up/down arrow keys. When done, press OK.

A filter factor can be applied if values appear unstable. Refer to menu branch

”Settings”.

NOTE: CORRIGO L10 is always factory calibrated with respect to analogue inputs.

Adjustments are therefore normally not necessary.

There is a rare possibility that f.ex. long wires cause erroneous readout. When in

doubt, measure the controlling value at the sensor with an accurate and calibrated

instrument under stable conditions to eliminate any faulty sensor.

Min/Max viewing of temperature values

The four analogue inputs for temperature can keep track of the min/max temperature

since the last reset was made. The ”Settings” section have a menu for activation of

this option ”SHOW MIN/MAX”.

To reset the min/max values, press the ? button and then the OK button. The min-

and maxvalue will be set to the current measured value.

Filtering - analogue inputs

The analogue inputs are factory set with a filter factor of 1. This feature is used to

suppress noise and hum that is introduced into the sensor circuits. The filter factor

can be increased, but use caution so that the factor for the controlling sensor is not

set too high so that it may jeopardize the control function.
