10.1.2 Setting of the pre-charge pressure monitoring
The pre-charge pressure monitoring is determined by the switching value ("FL1). This is
calculated as described in the following and can be checked in the main menu.
FL1
= T.VAL – Td.Lo
The output switches as soon as p
0
leaves this range. The output will switch back when the
pressure enters this range. The lower switch-back value is just below the lower switch
value.
