Components of the load cell
A- 2 m connecting cable
B- Flat washer.
C- Adjusting pin.
D- Locking ring.
E- Load cell body.
Procedure for installing load cell
Essential condition : the hook of the lifting system should be free of any load.
- Position the adjusting pin as a function of the load range and wire rope diameter (see p. 4).
- Remove the tightening bracket (K).
- Position the load cell on the wire rope near the dead end/fixed point. The connecting cable
should be uppermost.
- Replace the tightening bracket (K) ensuring that it is correctly positioned depending on the
diameter of the wire rope. (See page 4)
-Adjust the tightening screws (J) symetrically (+/- 0.5 kgm) to ensure that there is no risk of
moving the load cell out of line with the wire rope. Excessive tightening may break the
bracket.
- Operate the lifting system up to the upper limit switch and ensure that the sheaving or
bottom block does not foul the load cell. If this happens adjust the upper limit switch so that
there is an appropriate distance between the load cell and the bottom block. Also check that
when the bottom block is in the upper position the load cell is not in contact with the
overhead crane.
- Wire the connecting cable from the load cell t the control box. Ensure that the cable is
secured.

Positioning the adjusting pin as a function of the effort in the wire rope
Important remarks
- Before loading and if no preadjustment has been made in the factory, unscrew the
adjustment screw at the most, because you risk to destroy the transducer.
- To select pin and bracket position, load has priority over wire rope diameter.
- Never remove the locking nut (G) because tare screw (F) could damage the
microswitch.

OPERATION AND ADJUSTMENT OF HF 85 LOAD CELL
The switch is 25 mA 24V AC or 2 mA 15 V DC. It is therefore necessary to check the
interface compatibility if HF 85 is not used.
Procedure for installation and connection
- Mount the HF 85 monitor to the DIN rail in the electrical control box containing the
lifting controls.
- Wire the high speed lifting contactor coil in series between terminals 07 and 08.
- Wire the high speed lifting contactor coil in series between terminals 15 and 16.
- Wire the electronic alarm, HF90/1, to terminals 03 and 04 taking care to observe
the correct polarity. The alarm function is desactivated automatically 15 seconds
after the detection of an overload condition.
- Wire the electronic flashing light, HF90/2, to terminals 04 and 05 taking care to
observe the correct polarity. This flashing light function remains active whilst there
is an overload condition.
- Connect the load cell wires to terminals 01 and 02 ( non –polarized)
- Connect the power supply to the monitor : 220Vac to terminals 09 and 10 or 380
Vac to terminals 09 and 11.
Note: If necessary connect terminals 12 and 13 to normally open (NO) potential free
contactor on the high and low speed lowering contactor to eliminate the possibility of
detecting an overload condition and therefore the triggering of the alarms during
lowering. In fact, the dynamic effects in the dead end wire rope are greater on
lowering than on lifting.

Test function
Once the load cell has been fitted and the various connections have been made to
the monitor, there is a test procedure to check the correct operation for the
installation.
-Check that the hook of the lifting system is free of any load.
- Press the test button on the front of the monitor.(This button has the effect of
simulating an overload condition ).
-Once the test button has been pressed, the LED « L1 » should light up whilst the
LED « L2 » will light up when the dynamic effect of the value of the trip point has
been reached. (see page 8, point 7).
-Simultaneously, the relays trip and the alarms should operate.
-When the test button is released, it takes 5 seconds for he contactors of the
monitor to reset themselves to the « ON » position.

OPERATION AND ADJUSTMENT HF 32 AND HF 85
Adjustment of the safety trip point
Essential conditions : - The load cell must be correctly installed and wired.
- The hook of the lifting system should be free of any load.
- A successfull operating test
Equipment required : - A load (“Pm”) equivalent to 100 % of the working load limit
of the lifting system .
- An additional load equivalent to 10 % of « Pm ».
ACTION EXPLANATION
1Lift the two loads
(100% + 10% of Pm)
by +/- 10 cm.
The additional 10 % load represents the overload value permitted under the
European directives.
If an overload situation is detected in the wire rope ( without lifting the loads)
the preadjustment of the load cell in the factory is too low for your lifting
system.
Solution: release the tare screw (F - see fig. 4) one turn at a time and restart
at the beginning of point 1.
2To adjust the safety
trip point.
Use the tare screw (F).
Warning : incorrect adjustment may damage the circuit – breaker.
Do not forget the locking nut (G). The switch is a normally closed contact
(NC), requiring the opening of the switch to set off an overload condition.
Turn clockwise to reduce the value of the trip point.
Turn anticlockwise to increase the value of the trip point
3Lower the loads
4Remove the
additional load (10%
of « Pm »)
5Lift load « Pm »
using slow speed
lifting
No overload condition should be detected.
However, should the overload condition be tripped, see point 7 : Dynamic
effects filter.
6Lift load « Pm »
using high speed
lifting.
No overload condition should be detected.
However, should the overload condition be tripped, see point 7 : Dynamic
effects filter.
7Dynamic effects
filter using
potentiometer
« EFF. DYN »
Under certain conditions, the dynamic effects may create an overload
condition which will set off the safety system. The potentiometer on the front
of the monitor acts as a filter for this phenomenon by slowing down the
reaction of the relays in relation to the opening of the microswitch. The
potentiometer « EFF. DYN » has an adjustment range of 0 seconds (-) to ± 3
seconds (+).
