ESCALATOR CONTROLLERS
Lester Controls offer a range of bespoke Escalator
Controllers for common types of escalator.
TYPE 1 (500h x 500w x 200d)
This is our basic relay controller for forward/reverse operation. Mains
isolator, 6 pin test socket with blanking plug and lifting handles on the top
of the cabinet are included. Three fault indicator lights are fitted to the
door to assist in fault finding.
The controller incorporates an ISM (intelligent step monitoring) unit
which provides additional safety checking for missing step monitoring as
well as brake lift and handrail movement. This system is fully compliant
with the BS EN 115-2:2010 part 2 rules for the improvement of safety of
existing escalators and moving walkways.

ANCILLARY EQUIPMENT SUPPLIED
• Top pit ½ way wiring junction box
• Bottom pit ½ way wiring junction box with
test socket and plug
• Remote engineer’s handset control station
• Inductive Proximity Switcher can be
supplied for the following functions:
• Motor speed detection
• Broke lift (x2)
• Handrail movement (x2)
• Missing step top and bottom (x2)
Sensors are E2A PNP type:
• M12-WP-B1 Sensing distance: 4mm
• M18-WP-B1 Sensing distance: 8mm
• M30-WP-B1 Sensing distance: 30mm
TYPE 2 (600h x 600w x 210d)
A basic controller as above but has the addition of a fault logging system
with remote fault display screen for mounting in the skirting. This system
also incorporates under/over speed monitoring of the main drive motor,
missing step feature, brake lifted and left and right handrail movement
monitoring, as required by the BS EN 115-2:2010 PART 2 rules for the
improvement of safety of existing escalators and moving walkways, using
the fault logger microprocessor board.
TYPE 3 (760h x 760w x 210d)
Again the same as TYPE 2 but with the addition of a VVVF drive for
slowing and/or stopping the machine during quiet operational periods.
This results in a good power saving; typically a 50% energy saving
when run at half speed. Also included is non-use monitoring through a
photocell beam at the top and bottom entrances. The panel size reduces
to 600h x 600w x 210d if the drive is to be mounted separately. Control
voltage: 110v AC. Signalling of additional safety devices: 24v DC.
