3. USER INTERFACE The front panel contains the display and the keypad, made up of 6 buttons, that, when pressed alone or combined with other buttons, are used to program the controller. 3.1 Keypad 3.2 Programming The operating parameters can be modifi ed using the front keypad. Access differs depending on the type: set point, frequently-used parameters (P) and configuration parameters (c).

Basics The main menu is the first page the user will see when starting the unit, from the main menu, the information, the setpoint and on/off menu can be selected. In the bottom right corner, the the user can see these menues and switch between these by using the “up” and “down” buttons. To select one of these manues, press the “enter”...

Program menu To enter the program menu, press the “prg” button and enter the password. From this menu, settings corresponding to inputs/outputs, control and operating mode can be changed. Changing I/O parameters In the input/ouput menu the following can be changed. The number of probes used, the type of probes used, the minimum value of the probes, the maximum value of the probe, the offset for the probes, the function of probe 2, the type of output (analog/digital), offset for analog outputs and the number of outputs.
4. COMMISSIONING 4.1 Preparing for operation operations, before starting the controller check that: Once having completed the installation, configuration and programming • The wiring is performed correctly; • The programming logic is suitable for controlling the unit and the system being managed; •...
5. FUNCTIONS 5.1 Probes (analog inputs) The probe parameters are used to : • set the type of probe • set the offset to correct the probe reading (calibration) • set the maximum/minimum current/voltage value • activate a filter to stabilise the reading •...

Mode 2:Reverse c0=1 “Reverse” operation is similar to ”direct” operation, however the outputs are activated when the value being controlled decreases, starting from the set point (St1). When the value measured is less than or equal to St1-P1 (in proportional only operation), all the outputs are activated. Similarly, if the value measured starts rising, the outputs are deactivated in sequence.

Mode 4: Direct/reverse from DI1 c0=3 The controller operates in “direct” mode based on St1 when digital input 1 is open, in “reverse” based on St2 when it is closed. Mode 5: Direct, St1/St2 from DI1 c0=4 The controller always operates in “direct” mode, based on St1 when digital input 1 is open and based on St2 when it is closed. SER10IRU0CN –...
Mode 6: Reverse, St1/St2 from DI1t c0=5 The controller always operates in “reverse” mode, based on St1 when digital input 1 is open and based on St2 when it is closed. 5.3 Validity of control parameters The parameters that defi ne the operating mode have the validity defined in the table below: Par.

Does not apply to analog outputs. Number of outputs To set the number of outputs used (for digital). Press the “prg” button and enter the password, then enter the input/output menu. Then navigate until “nbr of DO” can be seen. This will set the number of digital outputs that will be used to control with the regulator. Var.
6. CONTROL The controller can operate with two types of control: • ON/OFF (proportional), in which the actuator either operates at full power or is off . This is a simple control mode that in certain cases can achieve satisfying results; •...
