The installation shall be performed by qualified personnel.
Please note the five safety rules!
4.1 Sensor installation
The sensor reacts to water contact at the two metal contacts (the sensor circuit is closed).
The assembly height of the sensor defines, at what level the water detector will sound an
alarm. The sensor cable can be lengthened up to a 50-meter dual-wire cable (2 x 0,5 mm²),
and 5 water sensors can be connected per input in parallel.
Sensor connection: 13-14 / 15-16 / 17-18 / 19-20 / 21-22
4.2 Snap-on fitting on mounting rails
The SHT 5001 water detector is installed into equipment racks and conduit boxes (mounting
rail 35 mm standard).
4.3 Relay connection configuration
When connecting additional devices to the potential-free relay, please note that the
switching capacity may not be exceeded.
Relay status in monitoring mode:
►
►
The relay is „energized“ (make contact closed/break contact open)
Relay status in alarm mode:
►
►
The relay „decreases“ (make contact open/ break contact closed)
4.4 Storage function adjustments
Two differing output messages can be defined for the sensor input:
Alarm message with storage function
►
►
(wire jumper at clamps 23-24)
: The alarm stays
on and the relay is switched on, until the message is turned off again by pushing a
button.
Alarm message without storage function
►
►
(without wire jumper)
: The alarm remains and
the relay is switched on, until the sensor no longer reports water. (For application as a
level indicator or pump control).
