Overview
HNM and HNE control relays are designed to monitor the levels of :
-
Conductive liquid (HNM)
- Any other product (HNE)
The HNM relay takes its measurements by means of resistive probes.
The HNE relay takes its measurements by means of discrete sensors.
Both these products actuate their output relay during emptying or filling of a tank.
General principle :
HNM relays control levels of conductive liquids. The principle is based on measuring the apparent resistance of the liquid between two submerged probes. When this value is below the preset
threshold displayed on the front face of the unit, the relay changes state. To avoid electrolytic phenomena, an AC current runs across the probes. A rotary switch on the front face can be used to
select the desired function and sensitivity range.
HNE relays control levels of products which may or may not be conductive. High and low-level data is produced by 3-wire output discrete sensors.
A green LED indicates the presence of the supply voltage.
A yellow LED indicates the status of the output relay.
A yellow LED flashes during the time delay.
Parameter setting :
A rotary switch on the front face can be used to select the sensitivity range, and the emptying or filling function.
A second switch can be used to select the number of levels (1 or 2), as well as the type of time delay in the case of 1-
level mode.
The configuration of these switches is taken into account on energisation.
If the switch is set to a non-conforming position on energisation, the product goes into fault mode, the output relay stays open and the LEDs flash to signal the position error.
If the switch position changes while the unit is operating, all the LEDs flash but the product continues to work normally with the function selected on energisation prior to the change of position.
The LEDs return to their normal state if the switch is reset to its initial position defined before the last energisation.

Control of two levels, emptying function
(Level : 2, LS emptying function (Low sensitivity : 250
Ω
to 5 k
Ω
), St emptying (Standard sensitivity : 5 k
Ω
to 100 k
Ω
),
HS emptying (High sensitivity : 50 k
Ω
to 1 M
Ω
).
As long as the liquid level has not reached the probe maximum, the output relay stays open. Once the max. level is reached, the contact closes, thus allowing the tank to empty (valve opens, pump
starts, etc). When the level drops below the min. level, the contact opens to interrupt the emptying process.
NB
: In two-level control mode the time delay for preventing wave effect is not active.
Control of two levels, filling function
(Level : 2, LS filling function (Low sensitivity : 250
Ω
to 5 k
Ω
), St filling (Standard sensitivity : 5 k
Ω
to 100 k
Ω
),
HS filling (High sensitivity : 50 k
Ω
to 1 M
Ω
).
As long as the liquid level has not reached the probe maximum, the output relay stays closed. Once the max. level is reached, the contact opens and pumping stops. When the level drops below the
min. level, the contact closes again and pumping restarts so as to make the liquid level rise again.
NB
: In two-level control mode the time delay for preventing wave effect is not active.
One-level control (min. probe), filling function, on-delay
(Level : 1 - on-delay, LS filling function (Low sensitivity : 250
Ω
to 5 k
Ω
), St filling (Standard sensitivity : 5 k
Ω
to 100 k
Ω
),
HS filling (High sensitivity : 50 k
Ω
to 1 M
Ω
).
When the liquid level drops below the probe for a duration longer than the value of time delay Tt set on the front face, the relay closes and stays closed until the liquid level reaches the probe again.
If the liquid level rises back above the level set before the end of the time delay, the relay does not close.

) or St filling (Standard sensitivity : 5 k

Ω
)
or HS filling (High sensitivity : 50 k

).
When the liquid level drops below the probe for a duration longer than the value of time delay Tt set on the front face, the relay closes instantly and stays closed until the liquid level reaches the
probe again and stays above it for a duration longer than time delay Tt set on the front face.
If the liquid level drops back below the level set before the end of the time delay, the relay stays closed.
One-level control (min. probe), emptying function, on-delay

),
HS emptying (High sensitivity : 50 k

When the liquid level rises above the probe for a duration longer than the value of time delay Tt set on the front face, the relay closes and stays closed until the liquid level drops back below the
probe.
If the liquid level drops back below the level set before the end of the time delay, the relay does not close.
