1.2 Theory of Operation

The UHC-P operates on 208-250VAC 50 or 60 cycle single-phase power. The main switch activates
a relay, which supplies line voltage to two distribution boards, two cooling fans and a 12-volt
transformer, which supplies a power supply. The power supply provides 5VDC to the
communication board and the distribution boards.

A ribbon cable connects the communication board to both distribution boards, connecting at J9.
Ribbon cables, which carry 5V DC, also connect the distribution boards to the displays. The
resistance of RTDs attached to the heater plates is monitored by the distribution boards. The board
switches power through solid-state relays to the heater plates when the resistance, which is used as
an indicator of temperature, falls out of the range for the product held in the cabinet.

The switch, transformer, communication board, cooling fans and power supply are mounted under
the top of the unit. There is a small dark lens portal on the upper right side of the cabinet, which
allows infrared communication between the cabinet and a Palm Pilot. The distribution boards are
mounted on the left side (as viewed from the front).

The parameters for holding temperatures are transferred to the cabinet’s communication board via a
Palm Pilot with special UHC-P software. All programming of the cabinet is done on the Palm.

Note: The illustrations
for these service
procedures are of the 4­slot full size UHC-P. The
procedures are similar
for the 2-slot and the
narrow models.

1.3 Start Up Indicators and Test Points

Upon startup, the communication board beeps. On the
distribution boards, an LED flashes rapidly for a few
seconds and then slows to one flash every two seconds.
The displays will show the version number of the
cabinet’s firmware and then the slot’s status.

2.2.4 Distribution Boards

1. Check for line voltage
between the heater
plate terminal on the
board and the terminal
block for the suspect
heater. Note: Line
voltage is only seen
when the slot is calling
for heat.

2. Check for line voltage
between the power
input terminal and the
terminal block.

3. Check for +5VDC at
the Power In terminal
between the positive
center pin and either
adjacent pin.

NOTE: After testing,
reconnect all
connections to their
original positions.

Figure 8: Testing distribution board.

2.2.5 Display

1. Connect the ribbon cable from a faulty display to the connector of a properly working display to
isolate the problem to the display or the distribution board.

2.2.6 Shorted Triac

1. Turn the suspect slot off and measure voltage between the suspect heater lead on the distribution
board and the terminal block With the slot off, there should be no line voltage. If the triac is
shorted, you will measure AC line voltage. If the triac is half waving, you will get DC voltage of
approximately one-half the line AC voltage.

2.2.7 Calibration

Calibrate the top and bottom plates in all four UHC slots by performing the following procedure
with the slots clean, empty and at operating temperature for at least 30 minutes.

1. Press the temperature key to ensure the slot is at setpoint.

2. Slide the Atkins sensor into a slot with the sensor facing upward to measure the top heater plate
or down to measure the bottom heater plate. Move the sensor to the center of the plate. To get an
accurate reading, the sensor must be within ±1 inch (25mm) of the center of the plate.

2.2.7 Heater Plate

1. Disconnect power to the cabinet. On stand-alone units, remove side and top panels. On stacked
units, see Service Procedures for instructions on accessing the top panel.

Step 7: With the Palm horizontal and
approximately one foot from the
receiving lens on the cabinet, tap the
Transmit button. The Transfer menu will
be displayed. A message will be
displayed when the transfer starts and
when the transfer is complete.

2. Disconnect the black heater lead and the two RTD leads (brown and red) of the suspect plate
from distribution board. Measure resistance of the heater from the black lead to any terminal on
the white terminal block. Resistance should be 140-150 ohms.

3. Measure resistance across the brown and red RTD leads. Resistance must be within a range of
104-148 ohms. Resistance at room temperature is approximately 107 ohms. See chart on Page
2-3 for resistance at different temperatures. If either resistance is incorrect, replace the heater
plate.

2.2.8 Display Meanings

1. SLOT TEMP HIGH OR SLOT TEMP LOW and no audible alarm. This is normal when

the slot is changing temperature in association with a menu change.

2. LLLL means the RTD indicates a temperature below 50°F (10°C). Unit will automatically heat

at 20 percent until temperature is above 50°F (10°C), then operate normally.

3. HHHH means RTD indicates the temperature is above 255°F (124°C), but below "Open" circuit
resistance, which causes SENS ALARM.

UHC-P Service Procedures

3.1 Re-addressing the Cabinet

If any board or display is changed on the UHC-P, the cabinet must be re-addressed. This essentially
tells each board which position it occupies. The cabinet must also be re-programmed with the Palm.
Changing the power supply doesn’t require re-addressing or programming. (Note: Re-addressing a
Narrow unit is slightly different and a separate button-push sequence is provided below.)

The process of re-addressing begins with the Palm. The security level has to be changed to admin in
the Palm software to access the re-address feature. The cabinet must be On. Follow these steps to re­address the cabinet with the Palm.

Step 1: Tap the key icon

at the top of the screen
(see arrow) to access the
security manager.

Step 5: The Cabinet
Configuration screen is
displayed. Make sure that
the proper slot size is
displayed. ie ( 2 slots, 4
slots, narrow). (NOTE: The
button-push sequence for
the Narrow unit is different
and covered in Steps 7N­11N on the adjoining page.)
With the Palm horizontal and
near the lens on the UHC-P
cabinet, tap the ReAddr
button in the bottom center
of the screen.

Step 2: Use the
Palm's keyboard
feature (see arrow)
to type admin in the
security manager
dialog box. Tap OK.

Step 6: The addresses of
the cabinet's boards will be
beamed to the cabinet. A
success message will
