The SKN controller is designed to control the rocess in LM/VM distillation columns.

Functions of the controller make the column o eration much easier. Main features of the

controller:

- Two inde endent out uts 16A 230/400V.

- Cooling water electrovalve (NO relay out ut)

- LM electrovalve (max 12V 1,5A NO/NC)

- VM motorized valve (max 12V 40mA)

- Four thermometers with resolution of 0.01oC, including one of two sensors, which

could control the VM valve

- Gra hic dis lay with high contrast

1. INSTALLATION RECOMENDATIONS

It is recommended to install the actuator in the area of heaters, in an enclosure rotecting it

against accidental flooding (having in mind such cases like leaking water connections, etc.).

At the same time, the enclosure must rovide free air flow that is necessary for cooling the

SSR relay controlling the heaters. The late should be fixed to the enclosure with lastic

s acers rovided in the kit. Using metal s acers may lead to a short-circuit, damage of the

a liance or even electric shock of the user.

The control anel should be installed in a

convenient lace, having in mind there is

a slot for memory card at the to of the

anel – flooding the a liance from this

side for sure would cause the electronic to

be flooded. The anel is rovided with its

dedicated bracket. Put the anel on the

bracket and then ull it down.

- Remember, the a liance is su lied

with a dangerous voltage. Its electrical

connection should be entrusted to a

erson with suitable knowledge and

authorization. It is forbidden to use the

a liance when its enclosure or wiring

is damaged, also if there is only

sus icion of malfunction of the system.

- The a liance may activate its out ut

at any time without signaling this

event, even if does not result from its

o eration cycle. It is forbidden to make

any mani ulation on the electrical art

of the system when it is connected to

the mains. It a lies also to the low-

voltage elements.

- Do not turn the a liance ON when

the heaters are not covered with liquid

– in case of unex ected turning ON

they could be damaged. It should be

considered to install additional

(mechanical) heaters switch.

- The SKN controller has incor orated

electronic relay (SSR) controlling the

heaters, however it does not ensure

reliable, mechanical heaters

disconnection. Moreover, in case of its

failure (overloading, short-circuit, etc.),

most likely it will su ly the heaters

with full voltage.

- The su ly connection should be

easily accessible. It must ensure quick

and trouble-free disconnection of the

system form the mains at any time.

- The wires and connectors used should

be suitable for the a liance ower. It

is recommended to install a ro riate

terminal box with a ro riate breakers

and differential rotection.

- Perform eriodical maintenance of the

a liance. After first few cycles of

o eration, check es ecially the

connections o erating under

significant load, retightening might be

necessary.

- It is forbidden to use the system in

laces that can catch fire from the

wires used, it is forbidden to store

flammable materials in the

neighborhood of the system o eration.

- Metal elements of the a liance

must be grounded. Please kee in

mind the fluids are erfect

conductors, therefore each

element must be grounded even

though a arently it is isolated

(e.g. with hose) from the other

elements.

- It is forbidden to leave the system

connected to the mains without

su ervision of a erson with suitable

knowledge and skills.

1.1. HIGH-VOLTAGE PART

The following diagrams show the exam les of connection of this art of the a liance. The

mains voltage that is necessary for the electronics shall be connected to L N terminals,

aying attention the hase wire should be connected to “L”.

Water valve. The SKN controller is not designed to su ly the water valve from its own

ower su ly. The water valve should be su lied from the mains 230V or se arate ower

su ly. The ZW connector should be sim ly considered as a switch, which will close its

contacts when the controller wants to activate the water circulation. It enables to use only

NC valves.

The heaters, de ending on their o eration voltage, should be connected according to one of

the diagrams, considering GH1 and G2 out uts as the serial switches. If the heaters (or their

sections) are of different ower, remember the ower connected to the articular out ut – it

will be needed for further configuration of the a liance.

ATTENTION! The “ rey” factory enclosure of the execution part ensures proper

coolin for current sup to 10A (for each G1 and G2). If the excepted current is to be

hi her, it should be considered to place the execution part in different enclosure

providin adequately better ventilation.

1.2. LOW-VOLTAGE PART

The control anel and the execution art

should be connected with the cable

enclosed. The res ective terminals should

be connected at both ends (i.e. GD-GD, V+-

V+, etc.). There is a connector at the anel

that could be easily detached.

The temperature sensor should be

installed in the column according to its

manufacturer recommendations, leaving

circa 1 cm of the metal art rotruding, if it

would be necessary to remove it ( ossibility

to hold it with liers, etc.). The measurement

oint of the column should be connected

with res ective terminal of the anel.

DS18B20 circuits, o erating in “normal” or

arasite ower, are used as the tem erature

sensors, the wire colors are im ortant.

Ground (GND) is brown, Data line (viewed

from the connectors and label side) (DTA) is

white, su ly is green. Mistake could

damage the sensor.

The LM electrovalve should be connected to

the EZ connector. Polarization (+/-) is not

im ortant. The electrovalve cable, due to

interferences created in it, should be shielded

and ossibly short, should not be ut in harness

with other cables. The controller enables control

of both NO and NC valves, a ro riate

configuration to be done in menu.

VM valve has an incor orated drive, thanks to

which, the controller may control its o ening

rate inde endently. It should be connected to

the MZ connector. Connecting here not

recommended element may lead to the out ut

failure. Polarization is im ortant, one of the wires is always red and it should be connected

to “+”. In case of inverted connection, the valve would o erate in o osite direction making

the column correct o eration im ossible. Correct installation could be check by means of

in ut/out ut test ( oint 3.2), where the symbol “+” visible on the dis lay means o ening and

“-” – closing.

2. FIRST TURN ON AND CONFIGURATION

After making sure that everything is installed correctly, fill u the tank or disconnect the

heaters and turn on the su ly. After a few seconds, the a liance should dis lay the main

screen with the column diagram and tem erature values in its articular elements. It is

recommended to erform a few o erations in the service menu.

1. Restore factory settings (o eration described in oint 3.3).

2. Check o eration of articular out uts, select o eration oints of VM and LM Valves

(3.2).

3. Configure initially the controller ( oint 3.4)

3. SERVICE MENU

This menu includes essential arameters of the controller. To enter this menu, ress and

hold for e few seconds the button, when the logo screen a ears ress the button

and wait for e few seconds. Navigation within this menu is done with the buttons,

select a ro riate function with . To exit this menu ress and hold for e few seconds the

button or turn ON the su ly again.

3.1. SEMI-AUTOMATIC MODE

This function makes it ossible to control the rocess with significant artici ation of the

user without alarms signalization. The user may, at any time, change the ower and turn the

cooling water valve ON/OFF. The only automatic function is VM valve control on the basis of

tem eratures entered by the user. The to value is an OFF tem erature, and the bottom

value is an ON tem erature. To sensor or bottom sensor is used to control this valve,

according to settings in menu 4.5. Setting of the VM valve o ening rate is done same way

as in the automatic mode.

T1…T4 designations refer to successive tem erature sensors (T1 is the head, T2 – bottom,

etc.). When entering this function, the clock visible in the u er art of the screen is

activated. It does not control the rocess, it is only to hel the user.

In this mode, data logging into SD card is also active. Holding for a few seconds the

button de ressed would cause the controller restarting. To acce t the new valve osition,

ress the button (editing this arameter) or sim ly move to edit next arameter ( ress

the button).

3.2. INPUT/OUTPUT TEST

In this menu, each out ut can be activated manually. The button activates the out ut,

the button deactivates the out ut. Transition between arameters is loo ed and it is

done with the button. To exit this menu ress and hold for e few seconds the

button or turn ON the su ly again.

Control of the VM valve, designated as MZ is done with the buttons. The visible “+’

symbol should cause the valve o ening and “-“ its closing, 0 means the valve is sto ed.

Control of the LM valve, designated as EZ is done with changing the values – above some

threshold the valve “engages” and below “releases”. To find the o timal value controlling the

valve, carefully increase the value and note when the valve o erates. Increase this value

further by circa 10...15%, then disconnect and reconnect the valve connector aying

attention if this o eration has roduced next and unequivocal vale o eration within 30 s.

Then enter the value obtained as Dt arameter value in out ut settings ( oint 3.4.2).

Setting too high values could cause the ower su ly overload and its shut-down (controller

restart). If such effect occurs without the valve o eration, it means this valve is not suitable

for this controller. Quite squealing or delayed o eration of the valve after disconnection of its

connector is a natural behavior.

3.3. RESET

Hold the button de ressed for a few seconds – the controller will restart. At the moment

when the logo screen a ears, ress the button, shortly after instead of main screen

the menu with a list of o erations will a ear. With the button move to “reset” and ress

the button. The controller will restart with factory settings. This function does not “cure”

the controller wonderfully and it is not a solution for all the roblems with its o eration that

usually might arise from not understanding its rinci al of work and wrong settings. Instead,

it causes necessity of resetting all the arameters.

3.4. ADDITIONAL SETTINGS

Hold the button de ressed for a few seconds – the controller will restart. At the moment

when the logo screen a ears, ress the button, shortly after instead of main screen

the menu with a list of o erations will a ear. With the button move to “additional

settings” and ress the button, first arameters – dis lay contrast – will come u .

Change the value with the buttons, confirm the value and move to next arameter

with the button. It is not ossible to move back to revious arameter. To save the

changes move across all the arameters. The controller will restart.

3.4.1 DISPLAY SETTINGS

Here you can select the LCD screen contrast.

3.4.2 OUTPUT SETTINGS

Here you can select the LCD screen contrast.

LM TYPE – s ecify the valve ty e (NO – normally o en or NC – normally closed)

Dt – arameter controlling the valve. The SKN controller controls the electrovalve in

so histicated way, in order to reduce heating of the valve and make it ossible to use valves

form a wide range of valves, which would not be suitable for direct o eration with this

a liance (e.g. excessive coil ower, o eration voltage different then 12V). Correct value of

this arameter should be obtained testing the valve o eration, available in the menu

“In ut/Out ut test” ( oint 3.2).

Then you could define how the heaters will work.

G1 modulated, G2 continuous – Heater connected to G2 out ut will o erate continuously,

even if set at minimum ower. Essential ower adjustment will be done with G1 heater.

G1 and G2 modulated. Both heaters will be turned On and Off at the same time.

G1/G1 power – the controller shows absolute ower in kilowatts (kW), not relative in

ercents. Therefore, to obtain correct value it is necessary to enter nominal ower of

articular heaters. Both the above ways of control have one common feature, the controller

realizes so called grou control with a few seconds eriod. Contrary to hase control, it

eliminates the necessity to use ex ensive noise filters, ensures good quality of control,

however it may cause light dimming in ace of heaters o eration. Therefore, it is

recommended to work in mode of G1 modulated and G2 continuous, where the modulated

heater will be su lied form different hase then lighting.

Max VM openin – defines the maximum valve o ening. When running the rocess it will

be im ossible to select higher valve o ening, reducing the ossibility to select higher

ca acity then the column can rovide and frequent rocess destabilization at beginning

hase of collecting the heart.

Min VM openin – means minimum o ening. When running the rocess it will be

im ossible to select lower o ening. Also the controller itself will no go below this vale if the

o ening correction o tion is active. Use a value at which the rate of collection is still

reasonable. Setting too low value or even total closing would cause the controller to

encounter a roblem with transferring to tails when the close time rinci le is selected, or

would case unnecessarily long collection of the heart and energy consum tion.
