Chapter 2
The communications cable from the optical bench or from another dispersion unit
connects here.
If more than one dispersion unit is connected to the system and this is the first dis-
persion unit in line, a communication cable will be connected from this connector
to the Accessory comms - in connector on the second dispersion unit.
The manual drain button can be pressed to drain the well. Users may wish to do
this if, for example, they need to drain the dispersion unit without having to start
the control software. Pressing the button once (for about half a second) will open
the drain valve. Pressing the button a second time will close the drain valve. If the
drain valve is left open for more than 15 minutes it will automatically close.
