5.2. Wiring

WARNING: Ensure all power is disconnected at the main circuit breaker before attempting any wiring. Improper wiring can cause electric shock or damage to the device.

The TM626 supports direct control for loads within its rated capacity. For light loads with high starting current impact, consider using an AC contactor for expansion control.

1. Connect the main power supply (AC 230V or 12V DC, depending on your model) to terminals A1 and A2.
2. Connect the incoming Live (in L) and Neutral (in N) wires to the corresponding input terminals.
3. For Output 1 (Channel 1), connect the Neutral wire to terminal N (shared with input neutral) and the Live output wire to terminal L out1. These correspond to terminals 3 and 4.
4. For Output 2 (Channel 2), connect the Neutral wire to terminal N (shared with input neutral) and the Live output wire to terminal L out2. These correspond to terminals 15 and 16.

6. Operating Instructions

The TM626 features five control buttons: MD (Mode), R (Recall/Reset), Left Arrow (Shift), Down Arrow (-), and Up Arrow (+).

6.1. Initial Power-Up and LCD Wake-Up

When first powered on or after a long period of inactivity, the LCD may be off. Press the R button for 3 seconds to wake up the LCD display.

6.2. Unlocking/Locking Keypad

To prevent accidental changes, the keypad can be locked. To unlock or lock the keypad:

• Press and hold the MD button for 3 seconds.
• The word 'LOCK' will appear on the screen when locked and disappear when unlocked.

6.3. Setting Current Time

After unlocking the keypad, you can set the current day, hour, and minute:

1. Press the Left Arrow button to select the digit or day to adjust (it will blink).
2. Use the Up Arrow (+) or Down Arrow (-) buttons to change the value.
3. Repeat until the current day, hour, and minute are correctly set.

6.4. Setting ON/OFF Programs

The TM626 allows you to set up to 8 ON/OFF programs for each of its two channels. Programs are displayed as 'C1 Px ON'/'C1 Px OFF' for Channel 1 and 'C2 Px ON'/'C2 Px OFF' for Channel 2, where 'Px' is the program number (1-8).

1. Press the MD button repeatedly until you see 'C1 P1 ON' (Channel 1, Program 1 ON time).
2. Use the Left Arrow to select the day(s), hour, or minute to adjust.
3. Use the Up Arrow (+) or Down Arrow (-) to set the desired ON time and day(s) for this program. You can select individual days or blocks of days (e.g., Mon-Fri, Sat-Sun, Mon-Sun).
4. Press MD again to move to 'C1 P1 OFF' (Channel 1, Program 1 OFF time). Set the OFF time similarly.
5. Continue pressing MD to cycle through 'C1 P2 ON', 'C1 P2 OFF', up to 'C1 P8 OFF'.
6. After 'C1 P8 OFF', pressing MD will take you to 'C2 P1 ON' (Channel 2, Program 1 ON time). Set programs for Channel 2 in the same manner, up to 'C2 P8 OFF'.
7. To clear a specific program, navigate to that program (e.g., 'C1 P3 ON') and press the R button. The display will show '----:----', indicating the program is cleared.
8. After setting all desired programs, press and hold the MD button for 3 seconds to exit program mode and return to the current time display. The keypad will automatically lock.

6.5. Setting Operating Mode

You can manually override the timer's programmed state or set it to automatic operation:

1. From the current time display, press the MD and Up Arrow (+) buttons simultaneously.
2. Each press will cycle through the following modes:
   • ON: The output is continuously ON, ignoring all programs.
   • AUTO ON: The output is currently ON, and will follow the next programmed OFF time.
   • OFF: The output is continuously OFF, ignoring all programs.
   • AUTO OFF: The output is currently OFF, and will follow the next programmed ON time.
3. Select the desired mode. For automatic operation based on your programs, choose either AUTO ON or AUTO OFF depending on the current state of your load.

6.6. Resetting

To reset the timer to its default settings (clearing all programs and resetting the clock):

• While in the current time display, press the R button for an extended period (e.g., 5-10 seconds) until the display resets.

7. Maintenance

• Clean the device with a dry, soft cloth. Do not use abrasive cleaners, solvents, or liquids, as these can damage the unit.
• The internal battery is designed to retain programmed settings during power outages. It is not user-replaceable. If the battery fails, the unit may need to be replaced.
• Ensure proper ventilation around the device if installed in an enclosure.

8. Troubleshooting

• Device Unresponsive/Frozen: If the timer freezes during setup or operation, try performing a full reset (see Section 6.6). If the device remains unresponsive, disconnect power for a few minutes and then reconnect.
• Channel 2 (F2) Not Working: Ensure Channel 2 is properly configured and enabled in your programming. Verify all wiring connections for Channel 2 (terminals 15 and 16). If issues persist, the unit may be faulty.
• Cannot Set Short ON/OFF Times (e.g., 5 seconds): The timer supports 1-second intervals. Ensure your programming accurately reflects the desired short duration.
• LCD Not Displaying: Press the R button for 3 seconds to wake up the LCD. Check that the main power supply is connected correctly to terminals A1 and A2.
• Programs Not Executing: Ensure the timer is set to an 'AUTO' mode (AUTO ON or AUTO OFF). Check that the current time is set correctly and that programs are not conflicting or overlapping unexpectedly.

9. User Tips

• Independent Channel Control: Each of the two channels can be configured and used entirely independently. This allows for separate timing schedules for different devices or circuits.
• Short Interval Applications: Due to its 1-second interval capability, this timer is well-suited for applications requiring very short ON/OFF cycles, such as programming school bells or intermittent device operation.
• Troubleshooting Freezes: If the device becomes unresponsive during setup, a hard reset (pressing the 'R' button for an extended period) or temporarily disconnecting power can often resolve the issue.
