5. Setup and Wiring

Proper wiring is crucial for the safe and correct operation of the timer relay. Ensure all connections are secure before applying power.

5.1 Power Supply Connection

The module can be powered by either a Micro USB 5V supply or a 6V-30V DC supply connected to the screw terminals. Do not connect both simultaneously.

Close-up of power supply terminals for 6V-30V DC input — **Figure 4:** Screw terminals for 6V-30V DC power input.

5.2 Load Wiring

The relay provides Normally Open (NO), Common (COM), and Normally Closed (NC) contacts. Connect your load to the appropriate terminals based on your application's requirements.

Wiring diagram for weak current control of a strong current load — **Figure 5:** Wiring diagram for controlling a strong current load (e.g., 220VAC) with the relay using a weak current trigger.

Weak Current Control Strong Current Wiring: As shown in Figure 5, the relay can switch a high-voltage/high-current load (e.g., 220VAC) using the relay contacts, while the module itself is powered by a low-voltage DC supply. The load's power source is separate from the module's power source.

Wiring diagram for sharing one power supply between the module and the load — **Figure 6:** Wiring diagram for sharing a single power supply between the module and the load.

Sharing One Power Supply Wiring: As shown in Figure 6, if the load operates on the same voltage as the module's power supply (6V-30V DC), you can use a single power source for both the module and the load, connecting the load through the relay contacts.

6. Operating Instructions

The DROK Timer Relay offers multiple operating modes and adjustable parameters. This section details how to navigate and configure these settings.

6.1 Setting Parameters

To enter the parameter setting mode, press and hold the SET button for 3 seconds. The display will show the current mode (e.g., P1.1). Use the UP and DOWN buttons to select the desired mode. Once a mode is selected, press SET briefly to cycle through its parameters (OP, CL, LOP). Use UP and DOWN to adjust the values. To change the decimal point position (for seconds, milliseconds, etc.), press the STOP button while adjusting the time parameter.

6.2 Operating Modes

The module supports seven distinct operating modes (P1-P7), each designed for specific timing applications.

Video 1: A detailed explanation of the DROK 200350 Timer Relay's operating modes and parameter setting process. This video demonstrates how to navigate through the different modes (P1-P7) and adjust their respective timing parameters (OP, CL, LOP) using the control buttons.

P1 (Time Delay On): Upon receiving a trigger, the relay activates (OP time) and then deactivates (CL time). Multiple triggers during the cycle have no effect.
P2 (Time Delay On with Reset): Similar to P1, but a new trigger received during the cycle will reset the timer and restart the cycle.
P3 (Time Delay On/Off with Stop): Similar to P1, but a subsequent trigger during the cycle will immediately stop the current cycle.
P4 (Delay then Open): This mode involves two parameters: CL (time to wait before the cycle starts) and OP (duration of the cycle after the delay). Intermittent triggers during the delay or active cycle have no effect.
P5 (Delay then Open with Loop): Similar to P4, but includes an additional parameter, LOP (Loop count), which specifies how many times the CL-OP sequence should repeat after the initial trigger.
P6 (Power-On Trigger): Similar to P5, but the cycle automatically begins upon power-on, without requiring an external trigger. This mode is useful for applications that need to start immediately when power is supplied.
P7 (Hold Open on Trigger): Upon receiving a trigger, the relay remains active (open) for as long as the trigger signal is held. Once the trigger is released, the relay will remain active for a specified OP time before deactivating. This mode has only one parameter: OP.

7. Maintenance

The DROK Timer Relay is designed for durability and requires minimal maintenance. To ensure optimal performance and longevity:

Keep the module clean and free from dust and moisture.
Avoid exposing the module to extreme temperatures or direct sunlight.
Ensure all wiring connections remain tight and secure.
Do not exceed the specified voltage and current ratings for the power supply and relay contacts.

8. Troubleshooting

If you encounter issues with your DROK Timer Relay, consider the following troubleshooting steps:

No Display/No Power: Check the power supply connections and ensure the voltage is within the specified range (5V via Micro USB or 6V-30V DC). Verify the power source is functioning correctly.
Relay Not Activating: Confirm the trigger input is correctly connected and providing the expected signal (high or low level). Check the selected operating mode and its parameters (OP, CL, LOP) to ensure they are configured as intended.
Incorrect Timing: Review the OP, CL, and LOP parameters for the selected mode. Ensure the decimal point is set correctly for seconds, milliseconds, or minutes.
Unexpected Behavior: Reset the module to factory defaults (if available, consult specific product documentation for reset procedures) and reconfigure the desired mode and parameters. Verify external wiring for any shorts or loose connections.
