Safety Features
HI-LIMIT RESET BUTTON
A hi-limit thermostat will turn off electrical power to the
heater and control circuits if the unit overheats. To
reset this thermostat, allow sufficient time (10-15 min-
utes) for the unit to cool down, then depress the reset
button located on the rear of the unit (Figure 5).
If the unit requires continuous resetting, contact your
Roundup authorized service agency.
FAULT MESSAGES
• If the platen thermocouple is disconnected or
“open”, the display will read “HI” and the heating
circuit will turn off (Figure 10). The platen thermo-
couple must be reattached or replaced.
• If the platen heater temperature exceeds 591°F
(310°C) the display will read “HI” and the heating
circuit will turn off (Figure 10). After the toaster has
cooled down, the unit must be turned off, then back
on to restart. If this condition repeats, contact your
Roundup authorized service agency.
• If the auxiliary heating temperature exceeds 360°F
(182°C) the display will alternately flash “HI” and
the platen setpoint temperature (Figure 10). The
heating circuit will not turn off. The toaster must be
manually turned off and allowed to cool down.
After the toaster has cooled down, the unit must be
turned back on. If this condition repeats, contact
your Roundup authorized service agency.
