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

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.

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.
AO1 Y1 - Heating or cooling
AO2 Y2- Cooling, damper, Plate exchanger or rotating exchanger
AO3 Y3 - Cooling

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.
