C
L10 is a new controller which has been designed to be easy to use and
OORIGO
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 C
simpler and more economic running of your control systems.

  • Page 6 Wiring AI Analogue inputs L10 has 4 analogue inputs, AI1...AI4. ORRIGO 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.
  • Page 7 Wiring Analogue outputs AO L10 has 3 analogue outputs, AO1...AO3. ORRIGO 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.
