3.4. Function

SYR Safe-T Connect is an effective leakage protection system that complies

with DVGW VP 638. It is adaptable to all SYR anges from DN 20 to DN 32.

Thanks to continuous monitoring, a leak is recognised early and water damage
is limited by automatically shutting off the water supply.

The Safe-T Connect with integrated LAN connection has electronic water me­tering (by means of a turbine), an electrically actuated shut-off, a pressure sen­sor to monitor the smallest leakage quantities and a multifunctional display.

When installed, it has a permanent encoded link to a server, which polls it to ob-

tain data from the drinking water installation such as: volumetric ow, total ow
per unit time, duration of the volumetric ow, pressure drop and temperature.

The maximum permissible parameters can be congured or changed directly

on the Safe-T Connect or via software on a smartphone or PC. Even if there is a
loss of Internet connectivity, the parameters will continue to be monitored. How­ever, there will be no communication with the server during this time.

Energy is supplied via the mains adapter. Batteries to provide a short-term back­up in the event of a power cut are supplied.

Error log

Some important terms in the menu are explained in the following table with
examples.

Function Explanation

Presence leakage Maximum possible water ow after opening a drawing point without

time limitation

Example:

The drawing with the highest ow is the bathtub. The capacity of the

bathtub is about 120 litres. Set the presence leakage value to 200 li­tres

Absence leakage More stringent monitoring of the maximum possible water ow when

the user is away for a longer period (holidays, etc.).

Example:
If the user is absent for a longer period, the absence leakage value
setting should be relatively low. For an occasional drawing, e.g. wa-

tering the house plants, a value of 10 litres is sufcient.

Leakage ow

If a water ow > 3,500 l/h is detected, the system assumes that there

is a leak.

Example:
After a factory time setting of 1 minute, the appliance shuts off.
This fault usually arises from a pipe breakage or similar problem.

Leakage time If a drawing is detected that lasts longer than the time setting at a de-

ned volume, the appliance shuts off.

Example:
After each volume setting, a time setting can be individually pro­grammed. If this is then exceeded when a drawing is detected al­though the volume is not reached, the appliance shuts off.

Presence and absence
function

Dened via the monitoring stringency of the Safe-T.

The desired function can be selected directly from the main menu
with the UP and DOWN buttons.

The limit values for “present” and “absent” must already be dened.

18

Operation

6.1.2. Setting the presence leakage on the appliance
(without LAN cable plugged in)

The menu settings are explained using the presence leakage by way of example.

Proceed as follows:

► Press the

button.

► With the

and buttons, you can change the value (from 100 l to 1500 l

in steps of 50 l).

► Conrm the setting with the

button.

6.1.3. Emergency open function

The emergency open function enables the valve to be opened in the event that
the SYR Safe-T Connect shuts off at the same time as a power cut (no batteries

inserted or batteries at).

The access to the emergency open function is underneath the control unit.
