5.1.1
Standby
In the standby mode the display is dark�
⇒ For the duration of 2 minutes, no key pressed and no suction channel opened�
en
♦ Change to standby mode�
⇒ Press any key�
or
⇒ Switch on an electrical appliance connected to the suction point� In this case, the suction channel is
opened immediately and the suction turbine is switched on�
♦ Standby mode is exited�
5.2
Operation
After switching on, the suction unit is in standby mode�
If a suction channel is activated, the suction turbine switches on with the last set suction power level and
the associated pinch valve is opened�
If the second suction channel is then activated, the second pinch valve opens�
The opening / closing of the suction channels takes place:
• Automatically:
An electrical appliance connected to a device socket (8A / 8B, Fig� 1) is
switched on / off�
• Manually:
By pressing a suction channel key (29)�
The letters of the opened suction channels (28) are shown in the display�
If a connected device is switched on, the corresponding suction channel can NOT be closed manually
with the suction channel key, but only by switching off the electrical device�
If the suction to a connected electrical appliance (e.g. a handpiece) does not react as required
(e.g. does not activate, even though a connected device is in operation) then the switch-on thresh-
old for automatic operation must be adjusted (see chapter 5.4.3).
5.2.1
Suction Power
The suction power for the suction unit can be set in 3 levels�
The current level is shown in the display (27)�
Change the suction power:
⇒ Press the [-] key (31)
♦ Reduce suction
⇒ Press the [+] key (33)
♦ Increase suction
The suction always starts with the last used suction level�
Adjustment of suction power:
The set suction level applies to all suction channels� Therefore, the power of the suction turbine is auto-
matically readjusted when a further suction channel is opened or closed, in order to reach the adjusted
suction power at the opened suction channels�
To disable the adjustment of the suction power:
In standby mode:
⇒ Press the [+] / [-] keys (33 / 31) at the same time for a duration of 3 sec�
♦ By pressing the [-] key (31), the display shows "OFF"�
The deactivated adjustment of the suction power is permanently indicated by the
"OFF" indicator above the [-] key (31)�
To activate the adjustment of suction power:
In standby mode:
⇒ Press the [+] / [-] keys (33 / 31) at the same time for 3 sec�
♦ The display will delete "OFF" in the display field above the [-] key (31).
If the suction performance is deactivated, the suction power at a suction channel can drop notice-
ably when the second suction channel is activated.
When suction level "3" and both suction channels are opened, only a reduced suction capacity is
available at the suction channels, since the performance of the suction turbine cannot be further
increased.
