The OPS-1 Light-Controlled Switch supports two trigger modes and two output modes:

1. Trigger Modes (Configured with JMP1 Jumper Caps):

• Bright Trigger Mode (Jumper Cap on 1-3 Position):
  The relay is activated when the photoresistor detects light increasing from dark to bright or gradually strengthening.
• Dark Trigger Mode (Jumper Cap on 2-4 Position):
  The relay is activated when the photoresistor detects light decreasing from bright to dark or gradually weakening.

2. Output Modes (Configured with JMP2 Jumper Cap):

• Relay Passive Output and Transistor-Driven Active Output:
  • Jumper Cap on 2-3 Position: Relay is enabled to operate.
  • Jumper Cap on 1-2 Position: Relay is disabled, reducing power consumption.

Assembly Instructions

1. Solder 3 x 1K resistors.
2. Solder 2 x 10K resistors.
3. Solder 2 x diodes (ensure correct polarity).
4. Solder 1 x electrolytic capacitor and 2 x ceramic capacitors (electrolytic capacitor has polarity).
5. Solder 1 x LED and 1 x transistor (both have polarity).
6. Solder the photoresistor, IC socket, and potentiometer.
7. Solder 2 x terminals and 2 x pin headers (ensure correct orientation of terminals).
8. Solder 1 x relay (relay has polarity).
9. Install jumper caps and IC (ensure IC is inserted with the correct orientation).

Trigger Modes for OPS-1 Light-Controlled Switch

• Bright Trigger Mode with Relay Enabled:

• • Set the JMP1 jumper cap to the 1-3 position and the JMP2 to the 2-3 position.
• Dark Trigger Mode with Relay Disabled:
• • Set the JMP1 jumper cap to the 2-4 position and the JMP2 to the 1-2 position.
