By carefully following the instructions outlined in this manual, you can confidently install, program, and operate your Grasslin timer to meet your specific requirements.
Installation
Installing your Grasslin timer is a straightforward process that requires basic electrical knowledge and adherence to local electrical codes. Before beginning installation, ensure that power is disconnected at the circuit breaker. This is crucial for safety and prevents electrical shock hazards.
Start by selecting the appropriate mounting location for your timer. The timer can be surface mounted inside a panel or flush mounted. The manual provides dimensions for the timer and its enclosure to help you plan the installation. Once the location is determined, mark the mounting holes and carefully install the enclosure using the supplied screws and spacers.
Next, connect the conduit hubs to the conduit before attaching them to the enclosure. Tighten the hub lock nuts securely, but avoid over-tightening. Carefully replace the printed circuit board, ensuring the spring latch is engaged at the bottom.
Finally, wire the timer according to national and local electrical and safety codes. Terminate all ground wires to the ground lug inside the case. After completing the wiring, restore power to the circuit breaker and verify proper operation of the timer.
Programming
Programming your Grasslin timer involves setting the time of day and defining the ON/OFF periods for your desired schedule. This process ensures that your timer operates according to your specific needs.
To set the time of day, rotate the timer dial clockwise until the time on the outer dial is nearly aligned with the triangle marker at the 2 o’clock position. Then, set the time to the minute by rotating the minute hand clockwise until the time of day (and AM or PM) on the outer dial is aligned with the triangle marker on the inner dial. Remember, do not rotate the dial or minute hand counterclockwise as this could damage the timer.
To program the ON/OFF periods, move the white tabs (trippers) on the outer dial outward at the start of the desired ON period. Move each adjacent tab outward until the desired OFF time is reached. Each tab represents a 15-minute interval, allowing you to create a precise schedule for your timer.
Once you have set the time and programmed the desired ON/OFF periods, test the timer to ensure it is operating correctly. You can do this by manually switching the timer to the ON position and observing the load. If the load turns on and off at the programmed times, your timer is properly programmed.
Setting the Time
Setting the time on your Grasslin timer is a crucial step in ensuring accurate operation. The timer features a clear dial with hour and minute hands, as well as an outer dial displaying the time of day. To set the time, follow these instructions⁚
Locate the Triangle Marker⁚ The inner dial has a triangle marker that represents the current time on the timer.
Rotate the Timer Dial⁚ Rotate the timer dial clockwise until the time on the outer dial is nearly aligned with the triangle marker. Remember, the AM and PM locations on the wheel represent 6 AM and 6 PM.
Adjust the Minute Hand⁚ Rotate the minute hand clockwise until the time of day (and AM or PM) on the outer dial is aligned with the triangle marker on the inner dial.
Avoid Counter-Clockwise Rotation⁚ Do not rotate the dial or minute hand counterclockwise, as this can damage the timer’s internal mechanisms.
Test the Timer⁚ After setting the time, test the timer by manually switching it to the ON position; Observe the load to confirm that it turns on and off at the correct time.
Programming the Timer
Programming your Grasslin timer allows you to customize its operation to meet your specific needs. Whether you want to control lighting, heating, air conditioning, pumps, or other electrical circuits, the timer offers flexibility in creating schedules that suit your preferences. Here’s a step-by-step guide to programming your timer⁚
Identify the Trippers⁚ The timer features a series of white tabs, known as trippers, located on the outer dial. These trippers control the ON and OFF periods of the timer.
Set the ON Periods⁚ Move the white tab (tripper) on the outer dial outward at the start of the desired ON period. For example, if you want the timer to turn on at 9⁚00 AM, move the corresponding tripper outward at the 9⁚00 AM position.
Set the OFF Periods⁚ To define the OFF periods, move each adjacent tab outward until the desired OFF time is reached. For example, if you want the timer to turn off at 1⁚00 PM, move the tripper adjacent to the 9⁚00 AM tripper outward to the 1⁚00 PM position.
Repeat for Multiple Schedules⁚ If you need to create multiple ON/OFF cycles within a 24-hour period, repeat steps 2 and 3 for each desired schedule.
Test the Programming⁚ After programming the timer, test it by manually switching it to the ON position and observing the load. Ensure that it turns on and off according to your programmed schedule.
Troubleshooting
While Grasslin timers are known for their reliability, occasional issues can arise. If your timer isn’t functioning as expected, follow these troubleshooting steps to identify and resolve the problem⁚
Verify Power Supply⁚ Ensure the timer is receiving power. Check the circuit breaker or fuse associated with the timer to confirm that it is not tripped or blown.
Inspect Wiring Connections⁚ Examine all wiring connections to the timer for any loose or corroded connections. Ensure that all wires are securely fastened to the appropriate terminals.
Check the Timer Override Switch⁚ If the timer is not operating in automatic mode, verify that the Timer Override Switch is in the AUTOMATIC position.
Test the Load⁚ Ensure that the load connected to the timer is functioning properly. Check the load for any signs of damage or failure.
Reset the Timer⁚ In some cases, a simple reset can resolve minor issues. Locate the reset button on the timer and press it to reset the timer’s internal circuitry.
