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

communicationoption.

L10 Temperaturecontrollerforuptothreesequences

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.

Thecontrollerhas been designed for mounting on a DINrail,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

meansof a code under the configurationmenu depending on the type ofapplication.

Thecontrollerhasayear-baseclock 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

mostimportantoperating 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.

Front panel assembly kit

When mounting CORRIGO L10 in a cabinet front use the FMK1 kit for easier mounting.

Thekitcontains a front frame with see-through lid andanintegrated mounting-rail.

Protection class IP65.

When mounting 2 CORRIGOs or one CORRIGO plus a relay unit next to each other in

the cabinet front use the FMK2 mounting kit. It contains the same items as FMK1

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,

nutsand 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

Theanaloguesensorinputs(AI1-4)haveacommonreferencepointthatis 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.

Thesignal neutral for analogue inputs andanalogue outputs and the system neutral

(terminal25)are internally connected.

Outputs

Analogueoutputs(0...10V)havesignalneutralascommonreferencepoint, terminal

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

type and have a common 24 VAC 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.

-Fanalarm: Intendedforusewith,forexample 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.

Mustbe 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:

-Cooleralarm

-Heatexchangeralarm

-Smoke alarm

-External alarm

AIAnalogue 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.

Digital outputs DO

Corrigo has 5 digital outputs DO1...DO5.

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

Outputs DO1...DO2 are of triac type for use with 24 VAC, 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 ControlDX-Coolingstage1

DO2 ControlDX-Coolingstage2 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 Controlfans

DO4 Control pump or electricheaterinterlock

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

willbeactivated during the cool-off sequence. To preventthis,interlock the

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

powerduringthecool-off period.

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

isidle and during the cool-off period.

DO5 Alarmoutput.

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.

TheoutputsAO1...AO3makeupthetemperaturecontrollingsequence.Function for

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

Y3?Y2 ?Y1 on increasing heat demand.

During normal running when the buttons are not in use a series of menu pages is

shown.Thedisplay alternates between a general displaywith product description and

clock, setpoint/actual temperature and output status for the control outputs

Y1,Y2 and Y3. The initial display shows the product name, date and time.

Setpoint/actual temperature display shows the current values as well as the control

status for the output signals Y1,Y2,Y3.

NOTE: When the system is stopped, the setpoint value is displayed as --- , meaning

the control function is disabled.

Alarms

When alarms are activated they are displayed in the alarm queue and also as a

flashing red light on the display panel on the front of the controller in the event of an

alarm.

Alarm queue

To check the alarm queue press the alarm button?. The display will then show

active alarms, the date and time when the alarm became active and the alarm status.

Alarm status Flashing ”AL” indicates that the alarm is active and has not been

acknowledged.

Steady ”AL” indicates that the alarm is active but has been

acknowledged.

Flashing ”OK” indicates that the alarm has aborted but has not been

acknowledged.

Acknowledging an alarm

Alarms are acknowledged by means of the OK button which will remove the alarm

from the alarm list. If the alarms are still active they will remain in the alarm list but

the flashing will be replaced by a steady ”AL” and a steady red light on the alarm

signals.

Arrows on the right-hand side show when there are more alarms in the queue.
