3. Product Overview

The TECNOSWITCH OR102DI is a daily electromechanical timer switch designed for controlling electrical circuits based on a programmed schedule. It features a 30-minute minimum switching interval and a 100-hour power reserve.

Figure 1: TECNOSWITCH OR102DI Daily Electromechanical Timer Switch. This image shows the grey timer switch with its transparent cover, revealing the orange and white dial for setting the daily schedule. The "tecnoswitch" logo is visible on the side, along with electrical connection markings (L, N, 1, 2, 3) and the CE conformity mark.

Key Features:

• Daily electromechanical timer.
• Minimum switching interval: 30 minutes.
• Power reserve: 100 hours.
• Unipolar 1NO contact type.
• Operating voltage: 230 Vac.
• Mounting options: Wall or DIN rail (2 modules).
• Conforms to EN 60730-2-7, EN 60669-2-1, EN 60669-2-3, EN 60669-1 standards.

4. Setup and Installation

The OR102DI timer switch can be installed either on a wall or on a DIN rail.

4.1. Before Installation:

• Ensure the main power supply is disconnected at the circuit breaker.
• Confirm the installation location is dry and protected from direct sunlight or extreme temperatures.

4.2. DIN Rail Mounting:

1. Align the timer switch with the DIN rail.
2. Press the timer firmly onto the rail until it clicks into place. The device occupies 2 DIN modules.

4.3. Wall Mounting:

1. Identify suitable mounting points on the back of the timer switch.
2. Mark the drilling locations on the wall.
3. Drill holes and insert appropriate wall plugs (not supplied).
4. Secure the timer switch to the wall using screws (not supplied).

4.4. Electrical Connections:

Refer to the wiring diagram printed on the device. Connect the power supply and load according to the following:

• L (Line): Connect to the live (phase) wire of the 230 Vac supply.
• N (Neutral): Connect to the neutral wire of the 230 Vac supply.
• 1 (Common): Connect to the common terminal of the internal switch.
• 2 (Normally Open): Connect to the load's live input. When the timer is ON, terminals 1 and 2 are connected.
• 3 (Normally Closed): (If applicable, for 1NO contact, this terminal might not be used or present). For this 1NO model, typically only 1 and 2 are used for switching.

After wiring, ensure all terminal screws are tightened securely. Restore power only after verifying all connections.

5. Operating Instructions

The OR102DI timer switch allows for daily programming of electrical circuits.

5.1. Setting the Current Time:

1. Rotate the central dial clockwise until the current time aligns with the reference arrow or marker on the timer's housing.

5.2. Programming ON/OFF Times:

The dial is divided into 24 hours, with each segment representing 30 minutes. Small pins around the dial control the switching.

1. To set an "ON" period, push the corresponding pins outwards.
2. To set an "OFF" period, leave the corresponding pins in their inward position.
3. Each pin represents a 30-minute interval. For example, to turn on a device for 1 hour, push out two consecutive pins.

5.3. Manual Override Switch:

The timer typically includes a manual override switch (often labeled with symbols like "I" for ON, "O" for OFF, and a clock symbol for automatic mode). Use this switch to temporarily override the programmed schedule:

• "I" (ON): Keeps the circuit continuously ON, regardless of the program.
• "O" (OFF): Keeps the circuit continuously OFF, regardless of the program.
• Clock Symbol (AUTO): The timer operates according to the programmed schedule.

Ensure the switch is set to the automatic (clock) position for programmed operation.

6. Maintenance

The TECNOSWITCH OR102DI is designed for minimal maintenance.

• Cleaning: Use a dry, soft cloth to clean the exterior of the device. Do not use abrasive cleaners or solvents.
• Inspection: Periodically check for any signs of damage, loose connections, or overheating. If any issues are observed, disconnect power and consult a qualified electrician.
• Power Reserve: The 100-hour power reserve ensures the timer maintains its setting during short power outages. If the device is unpowered for an extended period, the time setting may need to be reset.
