SALAMANDER ELECTRIC BROILER - SERVICE PROCEDURES AND ADJUSTMENTS
SERVICE PROCEDURES AND ADJUSTMENTS
Certain procedures in this section require electrical test or measurements while
power is applied to the machine. Exercise extreme caution at all times and follow Arc Flash procedures. If test points are not easily accessible, disconnect power and follow Lockout/Tagout procedures, attach test equipment and reapply power to test.
INFINITE SWITCH TEST (208V/
240V)
Disconnect the
electrical power to the machine and follow lockout / tagout procedures.
NOTE: Refer to AI3829 in WIRING DIAGRAMS for switch terminal locations.
1. Remove
2. Connect a voltmeter to the output terminals H1 and H2.
3. Reconnect power to machine.
4. Turn knob to the desired setting.
5. Compare the percentage of ON time to OFF time.
NOTE: ±7.5% tolerance allowable.

RACK SPRING TENSION
ADJUSTMENT
1. Access the springs on the bottom of broiler.
2. Tighten nut to adjust rack spring tension. Adjust both springs equally so there is approximately 3/4" of thread above the nut. If additional rack spring tension is required, tighten each nut an additional 2-3 turns.
3. Check for proper operation.
3 HEAT SWITCH TEST (480V)
Disconnect the
electrical power to the machine and follow lockout / tagout procedures.
NOTE: Refer to AI3830 in WIRING DIAGRAMS for switch terminal locations.

SALAMANDER ELECTRIC BROILER - SERVICE PROCEDURES AND ADJUSTMENTS
1) If both measured values are approximately the same as listed in the machine information table, then heating elements are functioning properly.
2) If one or both of the measured values do not agree with the values listed in the machine information table, then heating element is malfunctioning. Turn broiler control switches OFF.
Disconnect the
Fig. 15
electrical power to the machine and follow lockout / tagout procedures.
HEATING ELEMENTS TEST
Disconnect the
electrical power to the machine and follow lockout / tagout procedures.
NOTE: On 208V/240V broilers, the two heat controls are Infinite load switches; On 480V broilers, the two heat controls are 4 Position 3 Heat switches.
1. Access the
2. Reconnect power to machine.
3. Set broiler heat control switches to the highest setting.
4. Measure the voltage at the heating element terminals and verify it against the data plate voltage.
A. If voltage is incorrect, see
TROUBLESHOOTING.
B. If voltage is correct, check current draw
(amps) through the heating element lead wires at the X and Z phases on the outlet side of the broiler terminal block. The X phase value is the current draw for the left element and the Z phase value is the current draw for the right element.
HEATING ELEMENTS.
a. Install a replacement heating
element then proceed to step 2.
C. If unable to check current draw, a resistance
check (ohms) at heating element terminals may indicate a malfunctioning element.
1) Remove lead wires from the heating element and check resistance. See machine information tables under SPECIFICATIONS for proper resistance values at room temperature.
a. If resistance is incorrect, install a
replacement heating element.
b. If resistance is correct, heating
element has tested okay. If heating element is still suspect, see TROUBLESHOOTING.
5. Check broiler for proper operation.
See machine information tables under SPECIFICATIONS for proper current draw values and the appropriate 208/240V ­WIRING DIAGRAM or 480V - WIRING DIAGRAM for heating element phase connections.
NOTE: Checking current draw is the preferred method over a resistance check when a clamp on type amp meter is available.

ELECTRICAL OPERATION
COMPONENT FUNCTION
Infinite Load Switch ... Two switches independently control the left and right heating elements on 208V and 240V
models. Depending on switch setting, provides a range of ON time from 7% to 100%.
3 Heat, 4 Position
Switch ...............
Heating Element
Assemblies ..........
Terminal Block ....... Provides connections for supply voltage to the broiler.
Two switches independently control the left and right heating elements on 480 volt models. Provides approximately 100% of total available power of 4.5 KW with both switches set to HI position, 50% at MED position, 25% at LO position, and 0% at the OFF position.
Provides heat for broiling food product. There are 2 element assemblies per broiler.
SEQUENCE OF OPERATION
NOTE: On 208V/240V broilers, the two heat controls are Infinite load switches; On 480V broilers, the two heat
controls are 4 Position 3 Heat switches.
