7 TROUBLESHOOTING
7.1 General
For safety reasons, your Sigma platform lift is fitted with a number of electrical and mechanical
interlocks and touch sensitive edges. If any of these devices are not in order or any component or
sequence is not working correctly, the unit will not operate. In the event of a breakdown, you can
independently check your system for faults with the support of the points listed below or contact the
service personnel. Under no circumstances may you manipulate, modify, or remove the safety
devices of the system.
In the event of a malfunction, the following instructions must be worked through completely, point
by point. Do not skip any step!
Before you start, consider the following points:
•
Visually inspect the entire installation for damage, deformations, etc.
•
Check that the system is switched on. If your lift beeps while driving or in the stop position,
please read the description of the beeper in the chapter "Battery charging system".
•
Please ensure that the lift cannot be operated from the call stations while the platform is
folded down or someone is operating the system from the platform.
•
Check whether the main switch of the platform, which is located on the left side of the
platform, is switched on. The green lamp on the switch must now light up!
•
Check whether the batteries (if any) in the call stations are empty and have them replaced
with new ones if necessary.
• Also note that the first call station to be activated by a command signal takes control of the
lift (provided that no one operates the controls on the platform), so no other call stations
can be used until that command signal is deactivated.
• When calling for service, please have the system number to hand. This is located on the type
plate on the front side of the stairlift and is marked with the serial number "LE xxxxx". This
number is the quickest way to identify your lift and provide you with efficient information.
