Master Pump Enable Key
Use the master pump enable key to enable and stop the pump. The LED is
green when the pump is 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 pump 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.
NOTE: For detailed information about the variables that control the status of
the pump—enabled or disabled—and the associated indication that is
provided by the pump LED, refer to Pump Operational Status in Section 6,
Troubleshooting.
Setup Key
Use the setup key to place the melter into and take the melter out of
the setup mode. When the melter is placed into the setup mode, the
automatic scan stops and the left and right displays are used to select and
read or edit operating parameters.
