D) How to install 942 Strain Link transducer on lift’s structure
1)
Strain link 942 and 699 electronics are to be
fixed and installed on the lift frame.
2)
Strain link 942 is to be fixed on a flat and clean
surface, without rust, paint grease or oil.
3)
Tighten the 4 screws to fix strain link 942 and
use only flat washers.
4)
Set electrical connections accordingly to
connection chart of this manual.
5)
Ground to earth 699 electronics and respect all
relevant safety and electrical regulations.
6)
Feed power supply to STRAINSENTRY and
wait 15 minutes before calibrating.

Code
Meaning
ER.10
OVER RANGE - Verify the mechanical fixing of 942 strain
link. Try to substitute the 942 and re-calibrate.
ER.22
High load sensitivity. Fix 942 to a more rigid part of the lift
frame or substitute it.
ER.23
HI value is too low (in engineering units).
ER.24
Load specimen is too low. Increase load.
ER.30
Damaged A/D converter. Substitute 699 Electronics.
ER.70
Electrical connection problem. Check connections and that
cable has not been damaged.
Ground to earth the 699 electronics and respect all the relevant safety and electrical regulations.
Once performed all the needed electrical connections feed power supply and wait 15 minutes, before
calibrating.
Measurement changes are displayed in tens of the used engineering units.
At 699 power on, or after a reset
, display will show in sequence
699F
, the firmware release version (i.e.
1.05
) and:
UCAL
, if unit is not calibrated or if default data are loaded
MCAL
, if it has been calibrated using the
MANU
procedure
Supplied material:
N° 1 699 Digital conditioner complete of mating connectors (removable screw terminal), with reference to
the ordered configuration
N° 2 Fixing screws, type M4 x 12 UNI 7687
N° 2 Nuts, type M4
Perform calibration of the installed
MultiRope MRL100
load measuring system when lift’s car is at
the lowest floor of the plant.
