P48 Lack Of Water Switch Input
[DIS, ALR, ERR]
This parameter enables/disables the management of
the lack of water input (see Par. 4.3.3, terminals 13
and 14).
It defines the behaviour of the unit when the lack of
water input is enabled and the switch is open:
• DIS (DIS): the unit doesn’t manage the information
coming from the "lack of water" input.
• ALr (ALr): the unit reads the "lack of water" Input
(enabled) and reacts, at the opening of the switch,
by displaying the corresponding alarm A06 on the
display, and keeping the motor running.
• Err (Err): Err, the unit reads the Lack Of Water
Input (enabled) and reacts, at the opening of the
switch, by stopping the motor and generating the
corresponding error E11. The error condition is
removed when the switch closes again and the
motor is started.
Default: ERR.
