Note
Vertical mode
When operating vertical applications, the system must be weight-balanced in every position,
e.g. by counterweights or springs.
Modications to the door drive
CAUTION
Loss of liability for defects and material damage
Changes to the door drive lead to the loss of liability for defects and compensation rights, and
the correct function of the door drive is no longer guaranteed.
Observe the following rules:
• Do not make any modications to the door drive (motor, control unit, power supply).
• Never remove the grounding-type (Schuko) plug of the SIDOOR TRANSFORMER and NT40
(e.g. by cutting). IT IS USED FOR THE REQUIRED DISCONNECTION FROM THE MAINS.
• The power supply cord of the power supply (SIDOOR TRANSFORMER, SIDOOR
TRANSFORMER UL or SIDOOR NT 40) cannot be replaced. Scrap the power supply if the
supply cable is damaged.
Notes on maintenance
The SIDOOR system should be included in the maintenance schedule for the system as a whole,
and inspected in the course of the maintenance intervals stated in the schedule.
An inspection should cover the following points:
• Visual inspection of the control unit for contamination and damage
• Visual inspection of the motor for dirt and damage
• Visual and mechanical inspection of the mechanical system, in as far as it is part of the
SIDOOR elevator system. This includes checking the following components:
• Attachment of the motor holder, deector pulley and mounting bracket
• Wear on the toothed belt
• Check and remeasure the parameters for the safety-relevant force and energy settings set
during commissioning.
• Eectiveness of safety-relevant functions, e.g. light barriers, emergency stop, two-hand
operation.
