Function
If the water film at the water sensor exceeds 0.5 mm the control device automatically triggers an audible alarm and switches off the
solenoid. The GEWAS 191A type also switches off the device connected to the control device.
To remove the alarm disconnect control device. Wait for approx. 5 seconds before reconnecting the device.
The alarm will also be activated if the water sensor has been disconnected.
Safety requirements:
This device has been designed and tested in accordance with the safety regulations for electronic devices.
However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures and special safety
advises given in this manual will be adhered to when using the device.
1. Trouble-free operation and reliability of the device can only be guaranteed if the device is not subjected to any other climatic
conditions than those stated under “Specification”.
2. Make sure to observe the standard regulations and safety instructions for electric, heavy and weak current plants, in particular
the national safety regulations (e.g. VDE0100).
3. If there is a risk whatsoever involved in running it, the device has to be switched off immediately and to be marked accordingly to
avoid re-starting.
Operator safety may be a risk if:
- there is visible damage to the device
- the device is not working as specified
- the device has been stored under unsuitable conditions for a longer time.
I
n case of doubt, please return device to manufacturer for repair or maintenance.
4.
Warning:
Do not use these product as safety or emergency stop devices, or in any other appli-cation where failure of the product
could result in personal injury or material damage.
Failure to comply with these instructions could result in death or serious injury and material damage.
What to do in case of an alarm
- The control device can only be switched off by disconnecting it.
- Try to find and remedy fault cause.
- Potential fault causes:
- The water sensor is defective or has been disconnected.
- The water sensor contacts are connected (e.g. by means of a piece of metal etc.)
- There is a water film at the water sensor.
- Reconnect the control device; make sure to wait at least 5 sec. after disconnection.
Operating and maintenance advise
1. The solenoid is servo-controlled; i.e. the pressure at the infeed side of the solenoid needs to exceed the outlet side pressure
by at least 0.5 bar. This condition is fullfilled if the water feed line is open and the water can flow freely at the solenoid outlet.
Unless this condition has been fullfilled the solenoid cannot open. In such a case remedy fault cause (e.g. activate water
infeed of the device connected), disconnect control device, wait for approx. 5 sec and reconnect again.
2. When dead the solenoid will always be closed. In order to guarantee the required sealing properties, you have to make sure
that there are no foreign objects (stones, sand etc.) in the solenoid line. We, therefore, recommend to clean the sieve insert of
the solenoid regularly.
3. After a short current failure the solenoid sometimes closes but does not open again. Disconnect control device and wait for
approx. 5 sec., then reconnect control device => solenoid will open.
4. In order to ensure long-time and trouble-free operation of the device, the functioning of the device has to be checked at regular
intervals (as is the case with any safety device). To do so produce an alarm at least once a month by short-circuiting both water
sensor contacts by means of a metal object (e.g. spoon, knife, etc.). Disconnect device; wait for approx. 5 sec, before reconnecting
the device. The solenoid has to react with a clearly audible "clack" sound. This is to make sure that even if the water is calcareous
and even if it is not regularly operated the solenoid is fully operational regardless of the calcareous deposits.
5. The control device should not operate without solenoid connected!
If the function of the solenoid is not required the solenoid must still be connected to the control device. The connection of the
solenoid to the water feed is not essential then.
6. The device has to be treated and handled carefully in accordance with the above specifications (do not throw, bump against, etc.).
7.
!!! Never use GEWAS in a humid environment. !!!
