ELPA 9

Function description

• Staircase time switch, electro-mechcanical
• 3 conductor connection and floor lighting, but without secondary switching (no longer permitted for new systems)
• Terminal layout same as ELPA 8
• No closed-circuit current consumption
• Toggle switch for permanent light ON
• Reliable due to synchronous motor drive
• Simplest possible time setting and direct delay time readout on absolute scale
• Precision mechanics and therefore exact switching period
• Very low sensitivity to interference
