If the depth sensor is used to obtain this alarm, the parameter must be calibrated according to the instructions given on the display in
the chapter 14.2.1 Use with depth sensor > Configurazione con livelli di protezione.
Note: if this alarm is active, the pumps start automatically.
- Minimum level alarm: the signal for this alarm may come from a float, a level probe or from the depth sensor. The level probe
or float must be connected to terminal N of the device and positioned in the tank in the lowest point that the liquid can safely
reach. If the depth sensor is used to obtain this alarm, the parameter must be calibrated according to the instructions given on
the display in the chapter 14.2.1 Use with depth sensor > Configurazione con livelli di protezione.
Note: in case of an alarm, the pumps stop.
Note: if this alarm is not used, the input N must be jumpered unless normally open floats or level probes are used. In
the latter case, it is possible to instruct the system not to use input N, following the instructions given on the display in
the chapter 14.2 Drainage configuration
For inputs and protections see Fig.12.
Motor thermal protection: the device has an input for the thermal protection of each motor. If the motor used is provided with thermal
-
protection, this protection can be connected to the terminals KK. If the protection is not present in the motor, the terminals must be
jumpered, unless they are already bridged by the factory. The terminals are visible in Fig.5.
- Oil probe protection: the device has an optional input for the protection of the oil chambers of each motor. You can connect the oil
probe cables to the corresponding inputs (OIL1 for pump 1 and OIL2 for pump 2). If there is water in the oil chamber, the device
generates an alarm, closes the relay corresponding to the pump (OUT1 for pump 1 and OUT2 for pump 2) and, activates the internal
buzzer, just if it is enabled. In case of alarm and if the device has a display, is possible to view the error message, and the connected
pumps will continue their normal operation.
6.2 Outputs connection
If alarms occur, this is indicated by the device in three ways:
- By the buzzer which can be activated and deactivated from the control panel, see chapter 14.4 Optional configurations.
- By the outputs OUT1, OUT2, OUT3 by switching of the output contacts. The alarm operating logic is the following: OUT1 closes
following malfunctions of pump 1, OUT2 of pump 2 and OUT3 for general errors.
- The current alarm log can also be viewed via the indications on the display, and also access the alarm history.
If connected externally they can control an alarm.
6.2.1 Floats connection
2 or 3 control inputs can be used which must be connected as follows:
System with 2 floats: in this case inputs B and C are used (A must not be used, and must be jumpered in the case of normally
-
closed floats). The floats in the tank must be positioned as in Fig.11. For electrical installation, see Fig.12.
If normally closed floats are used, it is important to jumper input A. Otherwise the pumps will not stop.
- System with 3 floats: in this case inputs A, B and C are used. The floats in the tank must be positioned as in Fig.11. For electrical
installation see Fig.12.
6.2.2 Level probes connection
2 or 3 control inputs can be used which must be connected as follows:
System with 2 level probes: in this case inputs B and C are used (A must not be used, and must be jumpered in Drainage
-
function). The level probes in the tank must be positioned as in Fig.11. For electrical installation, see Fig.12.
It is important to jumper input A. Otherwise the pumps will not stop.
System with 3 level probes: in this case inputs A, B and C are used. The level probes must be positioned as in Fig.11. For
-
electrical installation, see Fig.12.
Common contact of the inputs A, B, C, R, N (See Fig.11). There is only one common contact for all the inputs and it
is connected to the odd terminals (starting from left from 1 to 11). So, if level probes or electric probes are used, the
common contact for the inputs: A, B, C, R, N must be connected to the terminals with odd numbers: 1, 3, 5, 7, 9, 11.
Level probes: can only be used with clear, clean water.
