Item Description

• The actual values of the temperature zones are displayed in columns under the icons. Zone
status is indicated by color: the zone field is colored green when the zone reaches set point,
yellow while the zone is heating up, grey it it has been temporarily switched off and red if in
alarm.
• When all zones have reached their set point values, READY will be displayed in the status
line. If zones are still heating up and have not yet reached their set point values, NOT
READY will be displayed in the status line.
• Under the Platen icon two temperature zones are displayed, one for platen
surface (1) and one for platen core (2); a cascaded PID-control controls the set point of the
core temperature; both zones have only one set point temperature.

The appropriate actual values (pump rpm, pressures) are displayed under the icons.
M1 will be displayed if Bulk Melter is operated with piston pump (option). In this case
the piston pump is controlled by pressure regulator.
Primary pressure: If the system is equipped with a (primary) pressure sensor, the
appropriate primary pressure transducer input will be displayed with number 1.
The primary pressure input can be controlled via the Pressure Set Point in Pump Control/
Pressure Control Screen.
Secondary pressure: If a second pressure sensor is equipped (usually in
combination with dual pump outlets), the appropriate pressure transducer input will be
displayed with number 2.
The secondary pressure input is just a readout function.
Pressure Discrepancy Alarm: If the display fields are highlighted red, it indicates
that the (optional) pressure discrepancy has detected an excessive difference between the
primary and secondary pressure. See point “Extended Pump Mode Settings Screen, Linear
Line Speed, Pressure Control” for further information.
