If damage is found, make a damage claim to the shipping company. After inspection, cut the banding and remove any other restrains from the Thermoglaze unit. Remove the banding and other packing material from the Thermolizer unit. Roll the Thermolizer, carefully, off the skid first and move it near the area where it will be assembled. .
2 Installation Venting: CAUTION TO AVOID ELECTROCUTING YOURSELF OR DAMAGING THE THERMOGLAZE, NEVER ALLOW WATER, STEAM, CLEANING SOLUTION, OR OTHER LIQUID TO ENTER THE ELECTRICAL PANELS OR CONNECTIONS Electrical: Model Dimensions Power Requirements TG50 88"L x 40W x 63"H See data tag Local codes prevail. The authorities having jurisdiction are stated in NFPA 96-1994 regarding requirements for the Thermoglaze.
3 Assembly Clean all parts with mild soap and water and let dry before assembly and applying electrical power to the equipment. The Thermoglaze unit is design for ease of assembly and use. The system is crated in a manner so there are few pieces to put together once the Thermoglaze is in place for production. After unpacking the system per the uncrating instructions, 1 item needs to be placed on the Thermoglaze to finish assembly: the glaze trough.

Calibration Procedure for Temperature and Cook Time on the Thermoglaze Model TG50 Turn off power to the TG50 before removing any access covers. This procedure should be performed only by qualified service technicians. Remove the electrical box cover on the oven to access the temperature and speed control adjustment potentiometers. The following is a photo of the location of the adjustment potentiometers for the temperature and cooking time for the Belshaw TG50 Thermoglaze.
Speed control/cook time adjustment: Turn on the oven and allow it to heat for 30 minutes. Put a glaze screen on the conveyor chains that run through the oven. With the oven in operation, time the leading edge of the screen as it enters the oven until the leading edge just leaves the exit end of the oven. Adjust the potentiometer until the desired time/speed is found. To increase the cook time, turn the potentiometer clockwise. To decrease the cook time, turn the potentiometer counterclockwise.

SB-0315R3 AFFECTS: TG-50, TG-25 PURPOSE: REVISED: 5/10/2006 JD VFD-0017-3 PROGRAMMING INSTRUCTIONS ENTER BUTTON DISPLAY ESC SCROLL UP/SCROLL DOWN Figure 1 Figure 2 Belshaw Bros., Inc. • www.belshaw.
General: Figure 1, above, shows the location of programming/navigating buttons on the face of the Altivar 11 (Belshaw P/N: VFD-0017). Figure 2 shows the navigation paths to various programming parameters. The following has been adapted from the ATV11 Technical Manual which can be found at http://ecatalog.squared.com/pubs/Motor%20Control/AC%20Drives/Altivar%2011/VVDED302026US.pdf Programming: Using Figures 1, and 2 navigate to the following programming parameters and set them as shown below in Table 1.
Returning VFD to factory default settings: Sometimes the easiest way to ensure that the VFD has the correct operating parameters is to return the configuration parameters to factory default and re-enter the few parameters changed for use with the TG-25 and the TG-50s.
Drive does not start, display off: Check that line voltage is present at the drive terminals Unplug all the connections on the drive U, V, W terminals and check that there is no short circuit between the phase and earth in the motor wiring or in the motor. Faults which cannot be reset automatically: The cause of the fault must be removed before resetting by switching power off and on again.
Faults which can be reset with automatic restart function, after the cause of the fault disappeared: These faults can also be reset by switching the drive off and on again.
