User Interface
There is a slide switch, used for local manual operation of the pump, and a DSUB9
type connector with male pin contacts for both remote control and to allow you to
vary the speed of the pump.
The mating DSUB9 connector may be purchased from an external vendor.
The specifications of the connector are as follows: Metal shell 9 Position D-Sub
Receptacle with Female Socket contacts.
See "EMC Warnings" for information about required back-shells, cable, and ferrite
bead.
The slide switch has two positions labeled as:
0: This is the OFF position, the pump and fan. When in this position, the pump
and fan are off and the optional inlet valve will be closed. The switch MUST be
in this position to allow remote ON/OFF operation.
I: This is the ON position, the pump and the fan operate when in this position.
The DSUB9 connector (Figure 26) has pins for both remote ON/OFF control and to
vary the pump speed. The pin assignments are in Table 14.
