1.4 Electrical connection
Warning:
Only use the power supply specified on the nameplate to run the S200 measurement and
monitoring device!
The device is delivered to run, by default, on a 230V/50Hz or 110V/50Hz power supply.
1.5 Safety Instructions
S200 WCS measuring and monitoring devices are manufactured and tested according to
standards DIN EN 61010-1 / VDE 0411-1. This device left the factory in good condition. In
order to maintain this condition, and to ensure the safety during use, the user must comply
with the information and warnings given in this manual. If it is suspected that operating in total
safety is no longer possible, we recommend that you turn off the device and disable it to
prevent any accidental operation.

All settings are accessible via a menu. Changing a defined value (for example).
Note:
This manual includes all available menu items. Depending on the selected code (see
the specific “Codes” paragraph), all menu items cannot be displayed, and/or, all menu
items cannot be selected.
6.1.1 Codes
There are 3 access levels to provide access using codes that protect the device from
unauthorized operation.
A) Code A - 00: all entries are locked, except codes B, C and D
B) Code B - 15: user code
C) Code C - 55: maintenance code
D) Code D - NN: code for factory service

6.2.2 Adjusting the backlight
The intensity of the backlight can be changed using the "backlight” menu.
Note:
Backlight intensity: it should be as bright as required. A backlight that is too bright
reduces the useful life of the display.
6.3 Flow graph bar display
The flow through the measuring cell should be set between 40 and 120 l / h. The flow rate is
limited to 120 l / h in the measuring cell. S200 WCS measures the flow and compensate for the
fluctuations.
Users should set the flow so that the indicator bar is in the middle.
There’s an indication of flow on the screen by small black block, the flow should be between 40-
120L/h (3-5 black block).
So we need to adjust the flow in order to keep 3-5 black block shown on the screen.
If the flow indicator in the display of the S200 is in the middle, then approx. 60 l / h of water will
flow through the measuring cell.
If this is too much for user, then he can return the sample water with the circulation pump.
This is what many customers do when, for example, we measure in hot water.
If we generally reduce the flow, then we have too long a dead time when using a long sample
water pipe.
