7.6.15.5 - Setting low pressure detection (KIWA)

The minimum pressure switch that detects low pressure can be connected
to any input (for the electrical connections refer to the control unit manu-
al). The system disabling function is obtained by setting the parameter Ix
relating to the input to which the signal to be used to disable the system is
connected on one of the values shown in Table 17.
The activation of the low pressure detecting function generates the block-
ing of the system after the time T1 (see par. 7.6.2 - T1: Low pressure
delay). The function has been conceived to connect the input to the signal
arriving from a pressure switch which indicates too low a pressure on the
pump intake.
When this function is active the symbol F4 is shown on the main page.
Tripping of this function causes the pump to cut out; it may be reset au-
tomatically or manually. For automatic reset of the F4 error condition, the
input must be deactivated for at least 2 sec. before the system resets.
To reset the cut-out in manual mode, press and then release the "+" and
"-" keys simultaneously
The behaviour of the function is summed up in Table 18.
When low pressure detection functions are configured at the same time on
different inputs, the system will indicate F4 when at least one function is
activated and will remove the alarm when none is activated.

7.6.16 - Setup of the outputs OUT1, OUT2

This section shows the functions and possible configurations of outputs
OUT1 and OUT2 of the I/O control unit, with wireless connection to the
device, set by means of parameters O1 and O2.
For the electrical connections, refer to the control unit manual.
The factory configurations can be seen in Table 19.
