The LED display (2) indicates the remaining time in minutes and
counts down backwards until it reaches a value of 0.
When the set time has expired, the drive stops and an audio sig-
nal is heard three times. The LED display (2) shows a value of ”0”
and the dot that identifies Timer mode stops flashing.
You can stop the drive while the timer is running at any time by
pressing the ”Start/Stop” button (4). The LED display (2) will show
a value of ”0” afterward in this case as well, and the dot that iden-
tifies Timer mode will stop flashing.
While Timer mode is in operation, you can increase or decrease
the time setting as required by pressing the ”1” key (6) and/or the
”10” key (5) as described above. After you have changed the time
setting, the time begins to elapse again and the LED display (2)
shows the remaining time in minutes as it did before.
Blocking or overloading the motor beyond the permissible motor
temperature causes the device to switch off automatically due to
the safety circuit. The LED display (2) displays the corresponding
error message. To eliminate the error, please check the operating
conditions. Also allow the device to cool off.
The device must be turned off and back on again.

rated and the Timer display switches to E + error number. First try

on. If an error is not eliminated even after waiting for a considera-
ble amount of time, please contact our service department. You
should always let us know what error code was displayed. This
