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 setpoint temperatures. When the
clock activates the standby mode, the setpoint temperature of each
component is temporarily reduced by a pre‐set standby delta.
Refer to Appendix B, Operating Parameters, Seven‐day Clock, 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.
