A 6 Preparation for commissioning
A 6.1 Calibration of the foot control
At commissioning or when changing the
compressed air conditions, the foot control
6
must be calibrated (with the motor
stationary).
Call up the “Calibration“ subroutine by
pressing the keys
2
↑
and
3
↓
simultaneously. The display
4
shows
“DO“ (down = lower pressure value).
The foot control may
not
be pressed
(pressure = zero). After about 1 second,
the value “No pressure“ is detected and the
display changes to “UP“ (up = upper
pressure value).
Now press the foot control pedal fully
(max. pressure) and press the key
2
↑
for
recording. The display changes to a
flashing “UP“. The
factory setting
for the
maximum pressure is
3 bar
(thats the ideal
setting).
After the foot control
6
has been
released, the calibration is completed by
pressing for a long time on key “REVER-
SE“
5
, and the value are saved.
If more than 10 seconds are required for
calibration of the maximum pressure
(display “UP“), the display
4
shows the
error message F2 and the input values are
not saved. In this case, the ELECTROtor-
que plus 4892 should be switched off for
about 5 seconds and the calibration
repeated.
If the maximum pressure reaches more than
5.5 bar, error 24 is displayed.
The increased pressure can lead to air
bubbles in the instrument lubrication.
Calibration is, however, possible. After
pressing the REVERSE key for 1-2
seconds, the calibration is completed and
the value is stored.
If the minimum pressure reaches less than
1.8 bar, error 25 is displayed.
Calibration is not possible. After pressing
the REVERSE key for 1-2 seconds, the
calibration must be repeated.
