Technical parameters
Device is constructed for connection in 1-phase main alternating current and must be installed according
to norms valid in the state of application. Installation, connection and setting can be done only by a
person with an adequate electro-technical qualifi cation which has read and understood this instruction
manual and product functions. The device contains protections against over-voltage peaks and disturbing
elements in the supply main. Too ensure correct function of these protection elements it is necessary
to front-end other protective elements of higher degree (A, B, C) and screening of disturbances of
switched devices (contactors, motors, inductive load etc.) as it is stated in a standard. Before you start
with installation, make sure that the device is not energized and that the main switch is OFF. Do not install
the device to the sources of excessive electromagnetic disturbances. By correct installation, ensure good
air circulation so the maximal allowed operational temperature is not exceeded in case of permanent
operation and higher ambient temperature. While installing the device use screwdriver width approx. 2
mm. Keep in mind that this device is fully electronic while installing. Correct function of the device is also
depended on transportation, storing and handling. In case you notice any signs of damage, deformation,
malfunction or missing piece, do not install this device and claim it at the seller. After operational life treat
the product as electronic waste.

Measuring probes
It is possible t use any probe (any conductive contact, it is recomended to
use brass or steinless-steel material).
- Manufacturer‘s recommended probes: SHR-1-N - stainless steel
sensor, SHR-1-M - brass sensor, SHR-2 - stainless steel mounted in PVC
cover, SHR-3 - stainless probe intended to be used in harsh industrial
environments, FP-1 - fl ood probe.
- Factory recommended conductor (certifi ed to be used in drinking water):
three-wire cable D03VV-F 3x0.75/3.2, cable D05V-K 0.75/3.2.
This device monitors level of a conuctive liquid in a tank by using six single probes or one 6-fold probe.
In case you use a tank made of a conductive material, it is possible to use it as a common probe C.
This common probe is connected to a pole of supply (for fi re-engines it means its body) in case of supply
voltage 12.. 24 V DC.
In case of supply voltage 230 V AC, the circuits are galvanically separated from the main.
The device is controlled by a three-position switch PUMP UP / OFF / PUMP DOWN. After switching into a
position PUMP UP or PUMP DOWN, red LED1 shines and then also LED2.. LED6 according to liquid level.
Output relay has 2 selectable functions. Funtion setting is done by a jumper on basic board of HRH-6.
Function 1: (for use in fi re-engines) - jumper is applied. In case of function PUMP UP and level reaching
L5, the relay controlling e.g. acustic signalization, permanently closes and indicated full tank. In case of
PUMP DOWN function and level dropunder level L3, relay priodically switches and under L2 it switches
permanently (indicates almost empty tank).
Function 2: (for keeping liquid level) - jumper is not applied. In case of PUMP UP, sensor is switched until
liquid reaches level L5. Then relay opens and switches again in case the liguid level falls under level L1.
In case of PUMP DOWN - relay is switched until liquid falls under level L1. Then relay opens and switches
again on level L5.
To eliminate LED fl ashing while level gurgle it is possible to delay reaction of probes (set delay 1..
10 s). According to conductivity of liquid it is possible to set sensitivity of probes (corresponding to
“resistance” of liquid).
* sensitivity is higher at both ends of a range of values
