Display Description: The display shows general indications, time, channel status (C1/C2, manual program, blocked/random/cycle switchings, holiday/pulse programs), and day of the week.
Button Functions: Buttons include DELTA (access menu/ESC), C1 (decrease/previous/channel 1), C2 (increase/next/channel 2), OK (confirm), and R (reset).
Menu Options: Settings (language, date, time, DST, coordinates, PIN), Program (create, modify, delete, copy), Bluetooth (enable/disable, password), Hour counter, Reset, Firmware menu.
Antenna Details:
- DY DCF77 Antenna: Receives time signals from Frankfurt, Germany, for automatic time, date, and DST setting. Range approx. 2500 km.
- DY GPS Antenna: Receives time from GPS satellites for highly accurate global time synchronization.
DW2 Two-Channel Digital Weekly Time Switch: Controls single or group loads with different time controls and a common time reference. Example: controlling heating and lighting in a church based on service schedules.
DWA Astronomical Version: Features astronomical and time programming, impulse, cycle, random, and holiday programs. It allows for automatic summer/winter time changes, up to 120 events, astronomical time correction, pre-defined cities, and 1 or 2 changeover contacts. It also supports manual override, PIN protection, and mobile APP programming.
DWA Application: Useful for controlling lighting based on sunrise/sunset times, especially in environments where external probes might be affected by pollution or vandalism.
E 232 Staircase Lighting Time-Delay Switches
The E 232 series (e.g., E232E-230 Multi 10, E232E-8/230 Multi10) are designed for staircase lighting, providing timed activation and a switch-off warning (double flash) to prevent sudden darkness, as per DIN 18015-2.
Operating Principle: Activated by a pushbutton pulse, the lights turn on for a set time T1. A pre-warning flash indicates the time expiration. The timer can be restarted by pressing the button again.
Application Environments: Ideal for staircases, passageways in public places, cellars, and garages where timed lighting and avoidance of sudden darkness are required.
E 234 CT-D Time Relays for Building Applications
The E 234 CT-D series offers various time relay functions for building applications, including ON-delay, OFF-delay, Impulse-ON, Flasher, Pulse former, and Star-delta starting.
Key Features:
- Functions: ON-delay (Delay on make), OFF-delay with auxiliary voltage (Delay on break), Impulse-ON (Interval), Flasher (ON/OFF first), Pulse former (Single shot), Star-delta change-over, Pulse generator.
- Control Supply Voltage: 24-240 V AC / 24-48 V DC or 12-240 V AC/DC depending on the model.

TL Line Twilight Switches
TL Line twilight switches automatically control lighting based on ambient light levels.
TL1 DIN Rail Version: Features 2 LEDs (contact status, threshold), adjustable switching delay, factory preset of 10 LUX, brightness range of 2-200 lux, screw-less design, and 1 module width.
TL1 Pole Version: Designed for pole/wall mounting with innovative design, easy installation, laser-etched wiring diagram, integrated brightness sensor (preset 10 LUX), adjustable threshold (2-200 LUX), switching delay (25s ON, 35s OFF), unlosable terminals, and IP54 protection.
Operating Principle: Switches on lights when ambient light falls below a set threshold and switches them off when light levels increase. Can be combined with time switches for energy saving.
Application Environments: Shops, office corridors, public passageways, car parks, parks, motorway lighting, tunnels, and service areas.
Example Installation (Commercial Building Lighting): TL1 switches on window and shop sign lights at dusk and can be timed off by an AG Timer. The TL1 Pole is used for motorway lighting, activating lights at sunset and deactivating at sunrise.
LCR Load Management Relay
LCR load management relays manage energy consumption by switching off loads sequentially when a consumption threshold is exceeded. They attempt to reset disconnected loads at preset intervals.
Operating Principle: Monitors consumption and disconnects loads (1 or 2) if the threshold is exceeded. Red LEDs indicate disconnected loads. The relay tries to reconnect loads when consumption drops below the limit.
Application Environments: Suitable for any situation requiring control of electric energy consumption within allowed limits, such as in printing offices where air conditioning may cause threshold exceedance.
Features:
- Terminals for power supply and current measurement
- Relay terminals
- Red LED for disconnected load indication
- Programming keys
- Backlit display showing measured power
- Active buzzer
- Keys for buzzer silencing (PR) and load rejection (OK)
- Indication for non-disconnectable and disconnectable loads
Connection: Via normally open (NO) or normally closed (NC) contacts, with specific current limits.
