How to Adjust the Paragon

Lid/Door Safety Switch

￿Wear firing safety glasses when looking into the peephole of a hot kiln.

￿Do not open lid or door until kiln or furnace has cooled and all switches are off.

￿DANGEROUS VOLTAGE! Do not touch heating ele- ments with anything. Disconnect kiln or furnace before ser- vicing.

The safety switch on your kiln turns off the heating ele- ments when the lid or door of the kiln is opened. (The digital controller will continue to operate.) When the lid or door is closed again, the elements will turn back on.

Indications that the safety switch is out of adjustment:

■The run light on the controller is lit but the elements do not heat.

■The safety switch turns off the elements part-way through a firing due to expansion of the door or lid at high tempera- tures.

We have included instructions for adjusting three types of lid/door safety switches:

The Tilt Lid

Safety Switch

Top-loading kilns use the tilt switch to turn off power to the el- ements when the lid is raised. The switch is mounted at the back of the lid.

1 Program the kiln to fire at full rate so the elements will turn on and stay on without cycling. (Please consult your manual to program a full rate.) After the kiln has fired for about a minute, have someone raise and lower the lid. Do you hear a clicking noise when you raise the lid? (The relays click when they turn the elements on or off.)

2 If you do not hear the relays click, close the lid and lift the tilt switch housing by hand. You can usually adjust the tilt switch by bending the housing up or down slightly.

3 If you still do not hear the re- lays click, remove the screws from the switch cover with a ¼” nut driver. Lift off the cover.

Remove the tilt switch screws. 4 Remove the 2 screws that se-

cure the tilt switch. Remove the switch. (Note how it is aligned so you can reinstall it correctly later.)

5 By tilting the switch, you should hear the relays turn on and off. If you do not hear the clicking, then disconnect the power to the kiln and look for a disconnected wire. If the wiring is okay, replace the switch. (You can also test the switch with an ohmmeter. See instructions on the next page.)

6 Adjusting the tilt switch changes the distance the lid opens when the elements turn off. You removed the tilt switch in step 4. With the switch out of the way, you now have access to the bolts that hold the switch mounting plate. Loosen the 2 bolts.

9 Reinstall the tilt switch. Repeat step 1 to test the lid. 10 Reinstall the tilt switch cover.

The Door Rotary

Safety Switch

The door rotary safety switch is mounted on top of the door hinge shaft.

1 Use a ¼” nut driver to remove the screws from the door switch cover. Lift off the cover.

2 Program the kiln to fire at full rate so the elements will turn on and stay on without cycling. (Please consult your manual to program a full rate.) After the kiln has fired for about a minute, open and close the door until you hear a clicking noise. (The relays click when they turn the elements on or off.) The elements should turn off when the door is opened 1” - 2”.

Lid/Door Safety Switch specifications

The Paragon Lid/Door Safety Switch is an essential component designed to enhance safety and reliability in various applications where lid or door operation is critical. These switches are commonly used in industrial machinery, appliances, and automated systems to prevent accidental operation and ensure user safety.

One of the main features of the Paragon Lid/Door Safety Switch is its robust design. Constructed from durable materials, it is engineered to withstand harsh environments and resist wear and tear over time. This reliability is crucial in preventing operational failures that could lead to accidents or equipment damage.

The switch employs a versatile actuator mechanism that can be tailored to fit different lid and door types. This adaptability makes it suitable for a wide range of applications, from industrial equipment to household appliances. The actuator’s smooth operation ensures that the switch can easily detect when a lid or door is opened or closed, providing a reliable signal to the control system.

Incorporating advanced technological features, the Paragon Lid/Door Safety Switch may include integrated safety circuits that comply with global safety standards. These circuits help mitigate risks and ensure that the system shuts down or remains inactive whenever the lid or door is ajar, preventing unintended operations.

Another notable characteristic of the Paragon switch is its ease of installation. The design typically includes user-friendly mounting options, which streamline setup and minimize downtime during installation. Furthermore, the switches can be integrated seamlessly into existing systems without requiring extensive modifications.

The Paragon Lid/Door Safety Switch also features a range of electrical ratings, allowing it to be used with different power configurations. This flexibility enables users to choose the appropriate switch for their specific application, ensuring optimal performance.

Additionally, operational feedback is often provided through visual or auditory signals, alerting users when the door or lid is not properly secured. This added layer of safety is invaluable in environments where machine operation without proper safeguards can result in serious injuries.

In summary, the Paragon Lid/Door Safety Switch stands out due to its durability, adaptability, and adherence to safety standards. With advanced technology and user-friendly design, it is an excellent choice for anyone seeking to enhance safety in equipment and machinery operation.
