Staircase Timing Light Relay LS-15

Staircase Timing Light Relay LS-15

I. Purpose: To turn off automatically the staircase lighting at a specified time.
IІ. Principle of operation: To operate the relay, it is necessary to ensure power supply to clamps 2 and 3. The phase must be connected to clamp 2. The relay is activated at the time of applying “Zero” voltage to clamp 4.
As one end of the lamp is firmly connected to zero / Notification “General” / for switching on the lamps should be connected only the phase. This is done by 1HO contact between clamps 1 and 2 of the relay.
IІІ. Technical Characteristics:
1. Supply voltage ~ 220V
2. Maximum continuous current ... 10 A
3. Setting range ...... .30- 3000 s
4. Ambient temperature - 20-40 о ˚С
5. Relative humidity up to 85%
6. Mass ............................ 80 g
IV. Installation: On standard DIN busbar - 35 mm. In Fig. 1 and Fig. 2 two ways of connection are shown - direct and by a contactor.
IMPORTANT! Before connecting the relay, check:
• External fuse state / max. 10 A /
• Define uniquely the three outlets to the relay: / Notification "Lamps",
Notification “Buttons”, Notification "General" /
• The presence of a "Phase" on the push buttons, or a pressed button is inadmissible.
Warranty: 24 months from the date of purchase, provided the installation and operating instructions are followed. It consists of a free repair at the expense of the manufacturer!
