2. Safety
2.1 Intended use
The low water level protection system (WMS) is exclusively designed for monitoring water
levels in heating systems according to EN 12828. Low water levels (lack of water) are
detected and reported. Any other use is unintended.
2.2 Foreseeable misuse
The low water level protection system (WMS) must not be used in the following cases:
• Water temperature above 120 °C
• Water pressure above 10 bar
• Welding work on the sensor
• Areas with a risk of explosion

3. Product description
The low water level protection system (WMS) consists of a fail-safe, self-monitoring
signaling unit with periodic self-test and a sensor.
The signaling unit and sensor are connected by a two-wire signal cable of up to 10 m in
length.
The product combination detects and reports low water levels (lack of water).

Signaling unit
The signaling unit contains indicators and controls in an impact-resistant plastic housing,
as well as all electronic components for evaluating and converting the sensor signal into a
digital output signal. The output is a zero potential relay contact.
The signaling unit is available in two versions:

3.1 Function
The WMS monitors water levels in heating systems. If the water level drops below
minimum, the low water level protection system alerts.
The operating principle of the low water level protection system relies on the conductivity
oftheheatingwater.Ifthereisaowofwaterthroughthesensor,thelowwaterlevel
protectionsystemindicatessufcientsupplyofheatingwater.Ifthereisnoowofwater
through the sensor, the signaling unit immediately alerts.
Sensor
The sensor consists of an outer electrode and an inner movable electrode. The two
electrodes are connected via a two-core cable to the signaling unit. The signaling unit
constantly monitors the conductivity (electrical resistance) between the two electrodes.
The inner movable electrode can be moved about 12 to 13 mm upwards from the water
7
ENG
for testing. As a result, the contact with the water is interrupted simulating a lack of water.
The signaling unit immediately alerts. An integrated spring returns the inner electrode back
to the starting position.
Signaling unit
The signaling unit constantly monitors the conductance of the water or the electrical
resistance between the two electrodes of the sensor. If the measured conductance greater
than20µS,orthemeasuredresistanceislessthan50kΩthesignalingunitindicatesa
sufficient supply of heating water and an error-free sensor circuit. The red alarm lamp is
unlit.Iftheconductanceislessthan20µS,ortheresistanceisgreaterthan50kΩ,thisis
interpreted as a lack of water, wire break or defective sensor circuit. The red alarm lamp is
lit.
The WMS is designed to be fail-safe and self-monitoring. The electronics in the signaling
unit check the entire low water level protection system several times a second.
Errors in the sensor circuit and signaling unit are displayed as alarms. The low water level
protection system can only be released if the entire low water level protection system is
error-free, a sufficient power supply is available, and the water level is above the minimum;
i.e., the red alarm lamp is unlit and the built-in relay is energized.
The green power light is lit when the low water level protection system is supplied with
mains voltage. The test button allows a functional check which simulates an alarm
condition.
3.2 Operating modes
The WMS 2-1 has an internal power failure interlock; that is, after a power failure, the
signaling unit must be released via the “Release” button or via an external release contact
