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.
Heater Key
Use the heater key to manually turn the component heaters on and
off. Pressing the heater 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 in this section) the heaters
automatically turn off. The heater key is used to turn the heaters back on after
correcting a fault condition.
Master Pump Enable Key
Use the master pump enable key to enable and stop the pumps. The LED is
green when the pumps are enabled and the melter is ready.
If the automatic pump on feature (Parameter 8) is disabled, then the master
pump enable key must be used to start the pumps when the melter is ready.
If any of the inputs are set up to use the pump enable/disable control option,
the pump motor will not start until the pump is enabled and the correct
voltage is applied to the input contacts. If the pump is enabled, but the input
voltage is not present, the master pump enable key LED will flash green.
