7.8.1 - O1: Setting output 1 function
Output 1 communicates an active alarm (it indicates that a system block has
occurred). The output allows the use of a normally open clean contact.
The values and functions indicated in Table 18 are associated with the param-
eter O1.
Table 19: Detecting the low pressure signal (KIWA)
7DEOH)DFWRU\FRQ¿JXUDWLRQVRIWKHRXWSXWV
signal has been connected.
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 (kiwa function)). 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 STATUS line
of the main page.
When it is in error condition F4, the input must have been deactivated for
at least 2 sec before the system can be unblocked. The behaviour of the
function is summed up in Table 16.

on different inputs, the system will indicate F4 when at least one function
is activated and will remove the alarm when none is activated.
