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.
Seven‐Day Clock Key
Use the seven‐day clock key to turn the melter's clock feature on and off.
When the clock is on, the temperature of each heated component is
automatically regulated based on a set of user‐defined schedules.
To accommodate daily shift work and non‐working days, four
clock schedules are available. Schedules 1, 2, and 3 are used to specify
when the heaters should turn on and off or when the melter should enter and
exit the standby mode. Schedule 0 is used to keep the melter in the last
condition dictated by the clock (heaters on or off, or standby).
When a clock schedule calls for the heaters to be on, the heaters
are regulated at their pre‐assigned set‐point temperatures. When the
clock activates the standby mode, the set‐point temperature of each
component is temporarily reduced by a pre‐set standby delta.
Refer to Appendix B, Operating Parameters, for information about setting up
the seven‐day clock and the standby delta.
If the melter is switched off while the clock is on,
the clock will automatically turn back on the next
time the melter is switched back on.
If the heaters are manually turned off at the time
that a clock schedule calls for the heaters to be on,
the heaters will not turn back on until the next clock
schedule calls for them to be on.
The clock will still operate when the melter
is faulting or is in the setup mode.
If F4 appears in the right display when you press
the clock key, the internal clock function has failed.

Standby Key
Use the standby key to manually place the melter into, and take it out of, the
standby mode. Using the standby mode during periods of time when the
melter is inactive helps conserve energy and allows heated components to
quickly return to their set‐point temperatures when the melter is once again
needed.
When the melter is placed into the standby mode, the temperatures of all
components are reduced down from their set‐point temperature by a pre‐set
standby delta. The melter will remain in the standby mode until the standby
key is pressed or the function of one of the operating parameters takes the
melter out of the standby mode.
If the melter was set up to use the manual standby timer (Parameter 26),
pressing the standby key will place the melter in the standby mode for the
period of time specified by the timer. After the manual standby time has
elapsed, the melter will once again begin heating all of the components to
their assigned set‐point temperature.
Using the standby key overrides the control of the melter (on or off) by the
seven‐day clock or a remote input.
Refer to Section 3, Installation, Setting Up the Melter, and to Appendix B,
Operating Parameters, for information about setting the standby delta and
the standby timer.
The melter may also be set up to automatically
enter the standby mode using a variety of
operating parameters.
