2. Area of application

The KEMPER KHS Mini System Control can be use for monitoring an water exchange in rinking

water systems. The water exchanges can be generate an ocumente as flushing logs with the

MASTER 2.0 control. The e icate water exchanges prevent stagnation in the rinking water with the

aim of maintaining the rinking water hygiene in the rinking water systems. Base on the KHS Mini

System Control MASTER, the MASTER 2.0 is a web-base further evelopment that no longer

requires configuration an rea out software. The system works entirely in epen ent of the operating

system. On top of that, some new functions have been a e that make the evice also interesting for

large buil ings.

NOTICE:

If two or more valves are simultaneously opene in a rinking water system,

un er certain circumstances pressure fluctuations or a large pressure rop can

occur in the system. For that reason, make sure beforehan that the require flow

pressure is continuously guarantee at all tapping points. It is recommen e to

not make simultaneous water exchanges.

5. CAN bus system overview

The basic version of the -MASTER/SLAVE- technology inclu es as the smallest solution the

-MASTER 2.0- System Control for water exchanging measures in the sector of rinking water an

for signal evaluation.

Furthermore, the -MASTER 2.0- System Control, using two integrate CAN bus connections, can

trigger up to 62 -SLAVE- controls an one irectly-connecte KHS water exchange group. Up to a

maximum of 31 -SLAVE- controls per CAN-BUS connection of the -MASTER 2.0- can be controlle

per CAN bus connection.

That means up to 63 KHS water exchange groups can be connecte an operate through

the -MASTER/SLAVE- technology. The accumulate total length of one CAN bus connection

can amount to a maximum of 1000 m (total length is thus 2000m).

5.1

Layout variants

Note:

The controllers must be connecte in series, as can be seen in Example 1.

During this, the -MASTER 2.0- System Control can be connecte within the

series (Variant 2) or as a final subscriber (Variant 1). Branches or start

connections, as can be seen in Example 2, are not possible. Furthermore, shorter

cable istances are recommen e .
