WARNING: INSPECTION, TESTING, AND REPAIR OF ELECTRICAL EQUIPMENT SHOULD BE

PERFORMED BY QUALIFIED SERVICE PERSONNEL. THE UNIT SHOULD BE UNPLUGGED WHEN SERVICING, EXCEPT WHEN ELECTRICAL TESTS ARE REQUIRED.

DANGER: USE EXTREME CARE DURING ELECTRICAL CIRCUIT TESTS. LIVE CIRCUITS

WILL BE EXPOSED. WHERE TESTING INDICATES "WITH POWER OFF", BE SURE THAT THE CONVEYOR AND HEAT SWITCHES ARE OFF AND TOASTER IS UNPLUGGED.

PROBLEM:

1. No heat and conveyor belts do not move. SOLUTION:

A. Check that toaster is plugged in. Check condition of power cord and plug. B. Check that conveyor power switch is on. C. Check circuit breaker in main breaker panel. Reset if necessary. D. Check that there is power at receptacle. Verify voltage is correct based upon the voltage listed on

the toaster nameplate.

E. Verify voltage is flowing through conveyor switch. F. WITH UNIT UNPLUGGED,

check wiring. Any wires or terminals with burns or discoloration from arcing should be replaced. All wiring, if replaced, should be same or higher rated wire.

G. If equipped with LED control, check for error message. “AL1” message is a defective center

platen probe. “AL2” is a defective booster platen probe. “AL3” is high temperature error of the center platen. “AL4” is high temperature error of the booster platens. “AL3” and “AL4” typically means the solid state relay is defective.

PROBLEM:

2. Conveyor belts move but no heat. SOLUTION:

A. Check that the unit is on. B. Verify voltage is flowing through heat switch. C. TURN OFF SWITCHES AND UNPLUG TOASTER. Remove left and right side covers. Remove

one screw and loosen one screw as shown in Figure 13. Lay unit on the left side (drive chain side). Swivel the bottom of control cabinet open.

D. Check for loose connections at terminal strip and temperature terminals (see schematic). E. Verify that the heater and sensor wires are connected to the proper controller. F. Replace all connections or components that have damaged terminals. Replace any damaged

wiring with same or higher rated wire.

G. Check the resistance of the sensor(s) (#503630). If sensor is open, replace. If LED, 1.09k ohms

at room temperature. If switch, 108k ohms at room temperature.

H. If equipped with LED control, check voltage into solid state relays. The voltage input from module

should be approximately 5Vdc. Voltage to heater should be 208Vac.

I. Check the resistance of the heater platens:

Center Platen (#139476): 20 ohms at room temperature Boost Platens (#503645): 54 ohms at room temperature each

check connections inside of plug. Remove switch side, side panel and

OWNER’S MANUAL

MODEL HST13 – AUTOTOAST™ VERTICAL TOASTER

PROBLEM:

3. Heater platens are hot; conveyor belts do not move. SOLUTION:

A. Check that conveyor switch is on and good. B. Make sure there are no loose connections at the switch. C. Check the fuse in the adjustment side panel. Replace with type AGC 1.5 amp fuse if necessary. D. Check motor to make sure it is connected properly. E. Check conveyor speed control setting(CH7, CH7B models). Adjust as needed. F. Check for voltage to speed control board (CH7, CH7B models). Check for voltage to the motor

(CH7C, CH7D models).

G. CH7, CH7B models, check for red light on the speed board. If red light is lit, the motor is working

too hard or in a stalled state.

H. Some speed boards have a green light (CH7, CH7B models). If green light is lit then power is

going to the board. I. Make sure the input voltage switch(es) of the speed board is set at 230V. J. CH7C, CH7D check capacitor for proper motor connections. K. CH7, CH7B check for DC voltage out of board to motor. L. Check all wiring to motor for loose connectors. M. Check drive system for loose chain or sprockets. Tighten set screws as needed. N. Check belts are not slipping on rollers. Check belts for tears and that the spring tension is

applying pressure to the upper roller.

PROBLEM:

4. Variable Speed Motor (#500940 90 VDC motor) Not Operating (CH7, CH7B Models) SOLUTION:

A. Verify correct voltage to unit and motor. B. Make sure conveyor switch (#501864) has power flowing through it. C. Check 1.5-amp fuses (#500061). D. Check for DC voltage to motor out of board (90VDC Motor). E. If red light on board is on, disconnect load from motor by removing chain. If it goes out, look for

conveyor binding. If it stays lit, replace motor –there is probably a gearbox problem.

F. Check DC amp draw to motor by putting meter in series with motor. (Pull wire from A1 on board,

put one lead to A1, other to wire pulled from A1.) When red LED on board is on, DC amp reading should be .23 amp approximately.

G. If green LED is on and red is not, make sure that there is varying DC voltage out of board to motor

(terminals A1 & A2 on board) as speed control knob is increased or decreased. H. Check ohm reading at motor cord plug (Range between 50-80 Ohms). I. Check for oil leaks on motor signifying bad seal or overheating that has taken place. In either

case, motor should be replaced.

PROBLEM:

5. Circuit Board (#140158) not working properly. (CH7, CH7B Models) DO NOT ADJUST POTS ON BOARD WITHOUT CONTACTING FACTORY!

SOLUTION:

OWNER’S MANUAL

MODEL HST13 – AUTOTOAST™ VERTICAL TOASTER

A. Verify AC voltage to board and DC voltage to motor from board. If there is AC voltage in, but no

DC voltage out, replace board. B. Check all connections on board and terminal strip. C. Verify that board is wired correctly. (See schematic in Owner’s Manual.) D. Make sure that switch on board is in 230v position. E. Check motor plug connection for grease or contamination. F. Check speed control pot with meter.

a. Two outside terminals should give a full value reading.

b. Each outside terminal separately with center terminal

should give a reading that varies from 0 to full value as

speed control knob is turned or full value to 0 according

to which outside terminal meter is connected.

PROBLEM:

6. Product is over or under toasted. SOLUTION:

A. Check toasting speed. Good toasting will occur in 10 to 23 seconds depending on product and

preference.

B. Check the gap settings. There must be compression of the bun as it feeds into the toaster.

Decreasing the gap will increase bun temperature and darken surface color. C. Check conditions of toaster platen sheet and belts. Clean both as noted in this manual. D. Make sure conveyor belts are not binding. E. Check drive system for loose sprockets or chain. F. Check that heaters are cycling. Do this by using an amp clamp on either of the wires from the

controller to the platen. You are looking for cycling. Also verify that the temperature controllers

have power. G. Check position of temperature control. This is located behind a small panel on bottom of toaster

on some units. After changing temperature setting, allow unit 20 minutes to stabilize.

PROBLEM:

7. Buns do not feed properly into toaster. SOLUTION:

A. Check condition of the toaster platen sheet to be sure buns are not sticking. Clean sheet as

described in daily maintenance. Replace if needed. Life of sheet is 1 – 2 months. Sheet should

be rotated daily. B. Belts need cleaning as described under the Weekly Maintenance. DO NOT USE ABRASIVES

TO CLEAN. C. Check toaster platen sheet installation. Sheet should be creased in middle so that platen is covered totally on both sides. D. Toaster gap set too close or too far. See instructions on Page 1, Number 10.

PROBLEM:

8. Outside Bun Toasted, Internal Bun not toasted. (No heat on Center Platen) serial no’s 0601TS0670 Through 928.
