Balance mechanism digital display calibration
The digital display (8) indicates setting of the balance mechanism on a scale of 00 (minimum set-
ting) to HI (maximum setting). In the unlikely event of this system requiring calibration, proceed as
follows:
Level the platform and apply centre lock (5) .
Turn the balance knob (4) fully clockwise to its maximum stop.
Press and hold the switch (9) for approximately eight seconds, until the digital display (8)
shows CA. Release the switch (9) . The display shows HI.
With the balance knob (4) still turned fully clockwise, press and release the switch (9) . The
display will now show LO.
Turn the balance knob (4) fully counter-clockwise to its minimum stop.
Press and release switch (9) .
If the calibration is successful, the display will now show 00.
If unsuccessful, Er will be displayed. Pressing the switch (9) again, or waiting for 15 sec-
onds, will allow the system to revert to its previous settings. Calibration may now be carried
out again.
After calibration, rebalance the head (See Balancing the head) .
Brake knob and drag control knob adjustment
The pan and tilt brake and drag controls may require adjustment after prolonged use. These ad-
justments should be carried out by competent persons as detailed in the Maintenance Manual.
The Maintenance Manual may be obtained from Vinten Broadcast Limited or your local Vinten dis-
tributor or from our website at www.vinten.com.
NOTE: If more than 15 seconds is allowed to elapse between steps, the system will
shut down and revert to its previous settings.
