CAUTION: Unintentionally activating function keys can, under the
correct circumstances, have undesirable effects on the melter or the
manufacturing process. Only personnel who are familiar with the melter's
setup and its connection with the manufacturing process should use the
function keys. Improper use of the function keys can result in erratic process
behavior or personal injury.
Heaters Key
Use the heaters key to manually turn the component heaters on and
off. Pressing the heaters key overrides the control (on or off) of the heaters
by either the seven-day clock feature or a remote input. The LED on the
heater key illuminates when the heaters are on.
When a fault occurs (refer to Monitor Melter Faults earlier in this section) the
heaters automatically turn off. The heaters key is used to turn the
heaters back on after correcting a fault condition.
