Sensitive edge safety bottom
The chairlift also has a safety edge at the bottom side of the chair. (safety bottom of chairlift).
If this safety device is controlled, the lift can not move in the downwards direction.
It is still possible for the lift to move in the upwards direction.
These switches are always interconnected in series with the wiring of the safety chairframe, only in the
direction where the safety is “needed”.
For example, on a chairlift mounted on the right of the staircase,(seen from bottom to top), the safety
bottom switches are interconnected in series in the left direction.
On a chairlift mounted on the left of the staircase,(seen from bottom to top), the safety bottom
switches are interconnected in series in the right direction.
2.3 Other inputs
Rotation monitor unit
This switch is triggered by a moving part, which is mounted on the
overspeed governor mechanism, which drives over the rail.
This contact is checked for an alternating value while moving
Rotation monitor unit (rmu) is connected to X9a. (rmu)

Service box
Multipurpose tool for:
- Programming the chairlift, with self chosen programmable speeds.
- Moving the lift in combination with bypass-connectors, when a
defect is active.
- Read out error-log.
The service box should be connected to x13 (service)
Bypass-connectors
Use for interconnection of safety-contacts.
Can only be used in combination with service box.
The bypass-connector should be connected to x15 (bypass) and
X3b (limit) and is activated (hold to run) by the C-button)
