Hach sc200 Manuel D'utilisation De Base page 6

The controller has four configurable relay switches and two analog
outputs. An optional analog output module can increase the number of
analog outputs to six.
Device scans
With two exceptions, the controller automatically scans for connected
devices without user input when it is powered on. The first exception is
when the controller is powered on for the first time before initial use. The
second exception is after the controller configuration settings have been
set to their default values and the controller is powered on. In both cases,
the controller first displays the language, date and time edit screens. After
the language, date and time entries are accepted, the controller performs
a device scan after the language, date and time entries are accepted.
Controller enclosure
The controller enclosure is NEMA 4X/IP66-rated and has a corrosion-
resistant finish designed to withstand corrosive environmental
constituents such as salt spray and hydrogen sulfide. Protection against
environmental damage is strongly recommended for outdoor use.
Controller mounting options
The controller can be mounted to a panel, to a wall or to a vertical or
horizontal pipe. A neoprene sealing gasket is included and can be used to
reduce vibration. The gasket can be used as a template for panel mounting
before the inner gasket component is separated.
