Connections and interfaces
The green LED at front of the Cl module illuminates after the module has been
switched on.
The mains switch, the device's fuse and the mains connection are located on the rear
of the chlorine module. The RS 232 interface for connecting the multi X 2500 is also
located on the rear.
The device's gas outlet is located in the bottom left corner of the rear panel. Depending
on whether the device is operated as the standard version or as an optional version, a
different outlet must be connected to the extraction:
Outlet "exhaust" (2 in Fig. 19): Outlet of the intake pump with filter (standard
version)
Outlet "waste" (3 in Fig. 19): Outlet of the exhaust air hose (optional version)
The filter on the "exhaust" outlet creates a vortex in the exhaust gas stream which
reduces the noise level.

The electrical connections for the measuring cells and the electrodes are located on the
inside of the chlorine module's rear panel. They cannot be interchanged. Each
connector only fits into one terminal.
