A separate control box on top of the unit houses a heater high temperature
limit device. This control box is labelled HEATER GUARD. On the front panel
of the control box is a HEATER LIMIT °C setting knob, a RESET button, a
HEAT indicator and a FAULT indicator.
The high temperature limit device will disconnect power to the heater if the
heater surface temperature exceeds a preset limit. The RESET button will
pop out and the FAULT indicator will light if the high temperature limit device
is tripped.
Adjust the HEATER LIMIT °C knob for the lowest value suitable for your
application. The high temperature limit device senses the surface
temperature of the heater, not the liquid temperature. The heater surface
temperature may be several degrees hotter than the fluid being heated.
During normal operation, the HEAT indicator will cycle on and off as required
by the unit'ss temperature controller. Should the heater temperature exceed
the set limit, due, for example, to low fluid level or control failure, the limit
device opens a mechanical relay to remove power from the heater. To
restore normal operation, correct the cause of the fault and then press the
RESET button.
