Rytec Insulated Roll-Up Door Turbo-Seal

Inspect all warning and safety labels. All labels should be intact, clean, and clearly legible. Replace any label when necessary.

Operate the door five or six complete open and close cycles with each activator installed with the door. Make any necessary adjustments or repairs. Refer to the associated manual supplied with each activator installed with your door.

Typical activators may include a floor loop, pull cord, push button, motion detector, radio control, or photo eye. The door open cycle is controlled by the activator. The door close cycle can be controlled by an activator or by a timer internal to the control panel.

Check the control panel for proper operation. If an adjustment or repair is necessary, refer to the Rytec System 4 Drive & Control Installation & Owner’s Manual that was shipped with your control panel.

NOTE: Photo eyes act as a safety device to prevent the door from closing if an object or person is within the photo eye beam. The photo eyes are not meant to be used as door activators.

Raise the door to the fully open position by pushing the up arrow key on the front of the control panel.

Break the beam of light on the front side of the door by placing an object between the photo eyes, transmitter and receiver.

Press the down arrow key on the front of the control panel. The door should not operate.

If the photo eyes don’t operate properly, the transmitter or receiver may be dirty. Clean as required using window cleaner and a clean, soft cloth. If cleaning does not solve the problem, see “PHOTO EYE ADJUSTMENT” on page 15 for adjustment procedures.

Repeat the procedure on the back side of the door.

WARNING: The disconnect must be in the OFF position and properly locked and tagged before performing the following procedure.

Is the reversing edge switch a normally open contact?

Is the PVC hose on the lower air input post?

Upload a photo of the resistor removed from the contact terminals and ohmmeter attached across the two terminals.

Did you turn the sensitivity adjustment screw clockwise until continuity is achieved?

Did you turn the sensitivity screw two full turns counterclockwise for a standard setting?

NOTE: Testing the reversing edge is the best way to determine sensitivity.

Upload a photo of the reattached resistor and wires and replaced access cover on the bottom bar.

NOTE: If the reversing edge is set too sensitive, the door may reverse direction during the closing cycle, without the reversing edge coming in contact with an object. If this occurs, readjust the reversing edge switch.

WARNING: The disconnect must be in the OFF position and properly locked and tagged before performing the following procedure.

2. Remove the side covers from the hood.

3. Pillow Block Bearings: The drum roll/door panel is supported by two pillow block bearings, which are located at both ends of the assembly. The pillow block has a grease fitting. (See Figure 31.)

The bearing should be lubricated quarterly using a lithium-based grease conforming to NLGI grade 2 standard. It should be a medium-viscosity, lowtorque rated grease, with an approved operating temperature range of –30°F to 200°F.

4. Drive Motor Gearbox Assembly: The oil level in the gearbox should be checked regularly. The oil level is checked at the plug located on the gearbox. (See Figure 32.)

Recommended oil for refilling the gearbox is SHC 630 synthetic gear oil. The gearbox is full when a small amount of oil runs out of the lower plug hole.

Replace the O-ring on the refill plug as needed to maintain a tight seal.

NOTE: Plug removal will depend on the horizontal or vertical orientation of the drive motor assembly.

WARNING: The disconnect must be in the OFF position and properly locked and tagged before performing the following procedure.

Counterweight securely blocked in the position shown in Figure 44

IMPORTANT: The 6 to 8 in. mounting height for each counterweight, as indicated in Figure 44, is adequate for most Turbo-Seal Insulated doors. However, for extra-wide or -short doors, the counterweights may have to be adjusted closer to the bottom of the side column. Also, the guides on the counterweight must be behind the conduit guides in the side column.

CAUTION: A counterweight can weigh in excess of 100 pounds. Make sure that safe handling procedures are followed and that each counterweight is securely supported during the following procedure. If not handled properly, a counterweight can damage door components and cause serious personal injury.
