Description

CDT6-LS Corridor and Staircase Lighting Timer

CDT6-LS controls corridor or staircase lighting with ON, AUTO and OFF modes. AUTO provides an adjustable 0.5–20min delay, while ON holds the output closed and OFF holds it open. The 18mm-wide switch mounts on a 35mm DIN rail and supports illuminated pushbuttons.

The common model CDT6-LS216S operates from 100–240VAC and has one normally open output with one end internally connected to L. Terminal 4 supplies the switched line to the load; this output shares the device's line connection.

Series Part Number Guide

CDT6-LS ordering layout with corridor switch function code, contact rating and supply — The common complete code is CDT6-LS216S. Function code 2 identifies the documented corridor switch configuration; its actual output is one line-linked NO contact.

Function code	2: corridor switch configuration with one normally open output internally linked to L
Contact rating	16: documented 16A common model; 10: additional 10A option in the ordering guide
Supply	S: 100–240VAC; A–Z letter combinations: custom voltage

Common model	Output	Contact Ith / Ie	Supply
CDT6-LS216S	One NO contact, internally linked to L	16A / 5A	100–240VAC, 50–60Hz

Lighting Modes and Timing

Mode	Operation
ON	Output remains closed while the device is supplied.
AUTO	Pushbutton-controlled timed lighting, with t set from 0.5 to 20min by the knob.
OFF	Output remains open.

CDT6-LS timing chart with AUTO, ON and OFF selection, timed output t, 3s control inputs and extended 1h lighting — The chart shows normal timed lighting, repeated control inputs and a 3s input selecting an extended 1h interval. A further 3s input ends the extended interval in the illustrated sequence. L–4 is the switched output; follow the chart for the required button sequence.

Application and Enclosure Dimensions

Staircase lighting example with CDT6-LS, multiple pushbuttons and shared lighting load — The application example shows a staircase lamp controlled from pushbuttons at different locations.

CDT6-LS enclosure drawing showing 90mm height, 18mm width and 65mm depth — Overall enclosure dimensions are 90mm × 18mm × 65mm, with 31mm and 19mm upper side-profile sections. Use the dedicated L/N/3/4 wiring diagrams and unit markings for terminal assignments; this drawing is an enclosure outline.

Select the load from the relevant lighting category and observe the neon indicator current limit. The selection document supplies the operating and wiring information above; request the applicable certification evidence from CNTD when required.

The manufacturer requires specially designed equipment and written confirmation for high reliability energy systems, applications involving personal safety or major property risk, harsh or outdoor environments, fire or explosion risks, and military or aerospace use.
