1A.a Fit the coupllng on the motor shaft by using a threaded bar

with S dia. (TAB. A 1 and A2) as shown in FIG. 1a, and

using 2 wrenches (hold a to avoid shaft rotatlon, and tum b

to draw the coupling on to the motm shalt),

1,5.a For a correcl assembly, lubricate the connecting surfaces

wlth oil 01' antiseizlng paste, For hot mouniing (not

recommended), do not overcome a temperature of 90°C,

Wllich causes Irreparable damages to oil seals,

b) with taper bush

1.4.

In case the bush is not provided with keyway (ílem 50 or 51

FIG. 1b), remove the key from motor or gearbox shaft

(reverse mounting).

1.5.b Carefully clean all surfaces contacting the bush by oil,

grease, etc., possibly usmg solvent, whether they belong to

motor, gearbox 01'fluid coupling.

1.6.b Fit the bush on the motor or gearbox shaft, intoducing a

screwdriver into the axial cut to make mounting easier;

assure that bush goes as far as the shaft shoulder.

For KRG series, fit half coupling (item 29

FIG. 4) on driven shaft, taking care that the shaft end does not protrude beyond face X.

Fit the fixing screw and the washer (items 25 and 26 for KR models; items 26 and 27 for KSD models) holding the motor or the gearbox

shaft still;

lock

the fixing screw with a torque wrench, respecting the torque reported in TAB. A 1 and A2.

Only for 13/15 KR KSD models (FIG. 3): fit the allan screw (item d) with flat washer (item e). Holding the motor or gearbox shaft

with a 38 mm wrench b 01'1the end c, lock the allan screw with a torque wrench a, respecting the torque reported in TAB. A2.

N.B.: For a correct assembly with the taper bush, strictly apply to the prescribed locking torque.

KR... - KSD - EK SERIES

TI'ansfluld fluld coupllngs are no! supplled wlth 011

Therelore 11IS necessary to achleve the lollowlng pracedure:

2.1 Positlon the coupllng axls horizontally (FIG. 6). turn I1until the

X mark cast Into the houslng gets al tlle top vertical (maxlmum

fill). so that tlle 011plug (item 13) Is Inclined as shown III the

plcture

FIIIwlth 011untll it overflows out 01 the filler hole. Whlle fllllng,

gently rack the coupllng on its axls to make sure all air excess

IS vented out of the clrcult, 01', Ifposslble. remove also tlle cap

located In correspondence on the other rotor. The quantltles to

be Intraduced are those reported in TAB. 01.

Screw the cap (or both caps) at the prescribed torque (TAB.

E) and make sure no leakages occur; otherwise use thread

sealant on filler plug tllreads.

The líllings marked X-1-2-3-4 may be chosen by the opel'ators

to meet the be sI performance In terms 01 start-up and steady

runnlng operatíon.

With the maxlmum fill X a conditlon 01 mlnlmum slip and

maxlmum performance Is achieved: the startlng torque !

nominal torque ratlo gets higher (values generally comprised

between 1.8 and 2.2) decreaslng the 011quantlty Inslde the

coupling (fII11-2-3-4), the opposite result Is obtained.

HIgh slip causes overheating of 011contalned in the worklng

circuit, wlth a consequent decrease IIIoverall performance.

For normal operatlng conditions, use only ISO HM 32 (01'

equivalent SAE 10W) 011 types listed in TAB. O. At low

amblent temperatures, use ISO HM 10 (01' equivalen!

SAE 5W) ol!.

For vertical mounted appllcatlons, the coupllngs

recommended 011fllls are reported in TAB. 01.

Fluid couplillgS Wltll delayed IIIIchambel (CK series) have the mal n

purpose ot reduclng tlle startíng torque / nominal torque ratlo to

values up to 1.6 . Thls aspecl Is Improved by furtherly enlarglng the

delayed flll chambel (CCK series) up to values of 1.3 of the above

ratío

2.8 The startíng torque Ilmítatlon can be achieved by reducíng the

oil quantlty ínto the worklng clrcult (till 2-3-4) without

IIlcreaslng the slip value a! rated speed. In standstill positlon,

the delayed lill chambel actually COlltalllS par! 01 the oil II11that

Ilows to the working clrcuit durlng start up.

2.9 The 011 passes Irom the delayed IIII chamber to the workíng

clrcuit tllrough calibrated orifices (FIG. 7) oWlng to

centnlugal lorce. Starting Irom slze 21 K, such orillces

dlameters can be modílied even when the coupllng is already

assembled, slmply by replacing a calibrated bleed plug (item

b) screwed IIlto the valve (Item 57). When reassembling the

valve, always remember to flt the copper seal (Item 58) and

make sure no leakages occur.

This technical solution allows a very simple and easy

operation, to be achieved in a very short time and (what is

more important) without disassembling the fluid coupling.

210 For each starting torque ! nominal torque ratío, Transfluld can

give the exact oíl lill. The Iluíd coupllngs with a delayed fill

chamber are generally foreseen with fill 2 (TAB. 02), while

the ones equlpped wlth a double delayed fill chamber with

fill 3 (TAB. 03).

As fluid couplings are supplied without 011, lollow the

instructlons reported at par. 2.1 - 2.2 - 2.3

2.6.

211 For vertical mounted appllcatlons, the coupllngs

recommended oíl fills are reported In TAB. 02 and 03. Oue to

delayed lill chamber peculiarity, for vertical mounting the

chamber must be downward.

ones In Viton (items 15 and 20), have lo be made of a special

material 100.

As eVldenced in TAB. F where the causes and the relalive

remedies are reported, a high temperature value may be

caused by the following condillons:

a) Insufficlenl oil fill

b) Higher absorbed power Ihan motor rated power

C) HIgli Clmbíenl lemperature

d) High starting frequency per hour

e) Excesslve slartlng time

f) Too many consecutive start-ups

Inadequate aír ventilation due to cover guardo

TRANSFLUID can supply all operating

data upon request.

3.2 After the first 20 days operalion, check the

oil fill (this operation to be carried out

with cold oil), the tightening of the screws,

the molor and the driven machine.

3.3 Repeal Ihe above checks every 6 months

For the KRG models, check the gap K

(TAS. C) of the elastic coupling. If the

torsional gap is excessive (about 2°),

replace the rubber elements.

3.4 Fluid couplings are supplied with fusible

plug al 145"C (120°C, 175°C and 198°C

settíngs are available upon request) as

shown in FIG. 14.

If the fusible plug blows al regular intervals

during normal service, then checks a), f) in

par. 3.1, and relalive T AS. F should be

considered.

3.5 In case the switching pin or the electronic

overload controller are mounted, check

that the dístances shown in FIG. 9 and 11

are wilhin the values imposed during the

assembly phase.

3,6 Oil should be replaced after 4000 hours

ACCESSORIES

Fluid couplings can be equipped, beyond the standard fusible plug.

with similar safety devices avoiding oil to escape, and that, in the

case 01 the electronic overload controller, can manage a lew more

palameters too.

The luslble plug is present as an element 01 further safety though

being set al a highel' temperature value.

51 SWITCHING PIN directly fitted 10 the couplíng covel plate

(FIG.9).

The electrical connection of the switch must have a lower

voltage than 230 V and a max current of 6 A (electrical

scheme details reported in FIG. 10).

Fllmly position the cam mounted lelay on its support, so tha!

the dlslance lrom the end 01 the switching prn is 6 mm.

11IS very imporlant to be within such a distance because, in

case the device is activated, the pln comes out owing 10

centrifugal lorce and intelcepts Ihe cam, switch es it on and

gives a conveníent outpul signal (to be used as an alarm or a

blocking impulse for the motor).

Notice that, in the configuratlon 01 an external driving impellel

the sWltching pin works in every condition; while, with an

external dliven Impellel' it can be correctly switched on only in

case of a slip increase due to overload 01 eccesslve load

5.2 ELECTRONIC OVERLOAD CONTROLLER, formed by a

proximity sensor and a speed controller. It detects the output

speed of the fluid coupling continuously.

When the load torque increases, slip increases too and speed

consequently decreases.

II the speed reduces down to the set threshold far a longer

time than specified, thls is signalled by the intervention 01 the

internal relay.

The said electronic device can be mounted on all fluid

couplings where not installed O.E.M. It is only needed to

replace 2 bolts positioned at 180' around the external crown

(as shown in FIG. 11) with 2 special ones having a longer

screw and nut.

As shown in FIG. 11, it is necessary to position the proximity

sensor in line with the 2 bolts at 180°, at a lower distance than

5 mm, while the controller can be fitted in the most convenient

place, chosen by the user, within a maximum distance of 20 m

(making the proximity connecting wire adequately longer).

Before connecting to the electrical power supply, always

verify the voltage.

The electrical connections have to be achleved according to

the scheme reported in the detailed instructions 01 the same

electronic device, setting and/or adjusting all the functions on

the control panel, as shown In FIG. 12.

a) Blind time lor starting TC, wlth a screw regulation up to 120

s, avoiding the intervention of the alarm during the starting

phase.

b) Speed range DS, by means 01 a Dip-Switch to be

programmed on 5 and 8 positions, setting relay condition,

proximity type, reset system, acceleration or deceleration.

c) Speed threshold SV to be screw regulated from 1 to 10.

The value 10 corresponds to full range set with dip-switch.

d) Reset R, locally executable with a manual switch or remote

connections.

e) Delay time T setting screw regulation up to 30 s. This

lunction delays possible alarms caused by sudden torque

variations.

The lunction of the timers respect to the state of the relays is

diagrammed in FIG. 13.

Leds (FIG. 12) permitting to keep some vital lunctions under

control are also present on the panel:

1) Speed level overtaken SS with a red light switching on as

soon as the set threshold is overcome.

Red alarm A lighting up when the internal relay switch es

on.

h) Green supply led ON pointing out that the device is

electrically supplied.

N.B.: For further details concerning electronic features and

connections, refer to the specific instructions supplied

with the device.
