All fault codes can be reset manually by switching On/Off the CS (cabin switch)
are reset automatically if the function in question is running (function verified). Fault codes L and H are reset
automatically if the battery voltage becomes correct. Fault code E is reset automatically if the control system
has not received any signal from the relevant control device for 6 minutes.
Example of sequence of fault codes:
Output No. 3 short-circuited.
13.2.3 Control devices
If a control device button is held down for too long, the control device is blocked and cannot be used for a number
of minutes. Fault code E flashes on the display. The fault is also indicated on a non-active coil control device with
a lock button, if this is connected to Ctrl 4. The LED on the coil control device then flashes the same number of
times as the number on the control device in question, see the list in section "13.2.2 Fault codes" on page 64.
Example: Control device 2 is blocked, the LED on the coil control device then flashes twice, goes out for a mo-
ment, flashes twice again, etc.

13.2.4 Supply voltage
Supply voltage
The illustrations below show the desired supply voltage for 12V and 24V systems. The specified voltage refers
to voltage when lifting. See also section "18.2 Maximum power consumption - Minimum recommended conduc-
tor cross sectional area" on page 76.
The lift is not working.
The lift is working but is issuing a warning. This voltage range is only recommended for
emergency operation.
The lift is working, but the voltage range outside the 'heart-marked' area is only rec-
ommended for operation for short periods.
The lift is working within the voltage range for optimum function and service life.
