4.4.1 Brief Description of Jumpers
*: If jumpers A, B and C are not covered, this constitutes the factory setting for an exter-
nal control signal 0-10 V DC. Other control signals ( 0-20 V DC, 0-10 mA DC) can also
be handled by the Basic. However, the control must be programmed for them in the fac-
tory.
Jumper Jumper Function
A Control: 1 step control (On/Off) or factory pro-
grammed*
B Control: 0-20 mA DC external signal or factory
programmed*
C Control: 0-140 Ohm external signal or factory
programmed*
A+B+C open control: 0-10 V DS external signal
(factory programmed, other controls signals
can be programmed ex works
D Stand-by Draining Off
E Main contactor switched off during blow-down
F Less frequent partial blow-downs (-50%)
G More frequent partial blow-downs (+100%)
