Troubleshooting functions
In addition to the error messages, the following troubleshooting functions can be used, depending
from the firmware installed on the unit.
C) DELTA view:
Already on older firmware versions it is possible to display the difference between the HI and TARE
calibration points – expressed as internal AD points:
1) Power-on / Reboot the 699+ keeping pressed the  + E pushbuttons, until the display shows :
2) P.xxx
3) Press  button to display r.yyy value
4) Take note of both xxx and yyy values, as xxxyyy is the difference between HI and TARE
5) Xxxyyy value gives indications about the sensitivity of the measurement element (sensor or Sensor
+ mechanical media like ropes, car metal frame, underfloor sensor) to the applied load used during
the calibration procedure of the measurement system.
Calibration Sensitivity = Xxxyyy /(HI - TARE).
Typical working calibrations have around 100 points/Kg
The above can be useful to have an idea of the sensitivity to the load of the measuring element (i.e 942
Strain Sensor attached to the metal frame of the car), or to verify the reason of an Er.24 (perhaps because a
MRL Multirope sensor was installed on the counterweight side of the ropes, or because the during
calibration Tare and Hi measurements were acquired with the same load inside the cabin, or the sensor
was not properly electrically connected to the instrument). For MRL installation a value lower than
typical can signal the need to increase the deflection of the ropes (with shorter screws), while a greater
value can indicate the need to decrease deflection (using longer screws), to avoid overloading of the
sensor. Please refer to the instruction manual specific for Your transducer or contact S2Tech, with the
troubleshooting data.
D) PERCENTAGE view:
During the Final Quality Test, performed individually on each 699Plus Weight Controller - prior to
delivery - the calibration done is stored permanently inside the unit and is used, as reference, to display
live measurement independently from Installer's calibration. Measurement is displayed - as percentage -
of the stored Reference Calibration and is used to show the live measurement, when lift is loaded and/or
unloaded.
Reference Calibration is performed at S2Tech with a sample load cell, acquiring the values of TARE and
HI while using a reference weight of 1.000 gram (corresponding of approximately 1.81mV analog signal)
and is stored in the memory of the device, independently from customer's own calibration.
When 699Plus is set for PERCENTAGE view, measurements are not depending from Customer's
calibration and are displayed as a percentage of the Reference Calibration.
Displayed value can range ±9999 (no decimals, with negative values indicated as 9999.)
With this view it is possible to understand if changes in the load correspond to changes in the percentage
value (so electrical connection is ok) or if they are enough wide to grant a correct calibration in the
engineering units chosen for the calibration.
1) How to activate the Troubleshooting function
At any time press for at least 5 seconds the E pushbutton, until 699Plus display shows tbls and a
measurement followed by a blinking comma at the rightmost bottom of the display.
Percentage displaying view is now active and can be recalled:
– during normal measurement
– in case of an error message
With this function it is also possible to show the internal AD points corresponding to the difference of HI
– TARE, as result of Installer's calibration:
– Press  pushbutton, to display n.abc value (as number)

Firmware: any
If measurement is negative, a decimal point on the bottom right side of the display is powered on
continuously (i.e. like when friction is "holding" lift in position, when ropes are released when cabin must
move down on the shaft).
To get back to standard measurement, keep pressed the E pushbutton, until on 699Plus display OPmd
again the measurement obtained, as result of Your calibration procedure.
E) Reset working parameters:
In case Installer messed up working configuration parameters and behavior of the unit is unpredictable, it
is possible to reset to default all the parameters using the following procedure:
1) Power-on / Reboot the 699+ keeping pressed the + + C pushbuttons, until the display shows
2) Use  and  to display CLrA
3) Press E to enter the password protection, so to be in position to enter the input field to set the
4) When display shows 0, use  and  pushbuttons to set the password that S2Tech supplied You
5) PASS is shown, to indicate that system accepted the password
Firmware: ≥1.41
6) Use  and  to display dFLT and press E to display current parameter "0"
7) Set dFLT to 1, using arrows, to confirm the activation of the reset function.
8) Press C to exit and after SAVE is shown and instrument resets, the unit is set to default parameters
After this procedure the percentage view parameters are still available, but any previously change to the
699 configuration is lost.
NOTE: when You recall this function, avoid any power loss to the system and do not press the reset
pushbutton until the procedure ends by itself with a reboot of the unit. Any interference during this
procedure will lead to a not working unit.
F) Instruction manuals download page
Instruction manuals of our products can be downloaded or viewed form the web
using the following link. On the new instruction manuals or on the usual labels
applied on the instruments, You will find a datamatrix code like the one on the
right, that if scanned brings Your mobile device directly to the manuals page.

– a,b,c,d,e,f are numbers and their sequence abcdef, represents the range of AD points
resulting from Installer's calibration. The abcdef value is to be communicated to S2Tech,
in case of technical assistance.
