Adjusting Temperature of an Individual Component
1. Press and hold the Tank, Hose or Gun key for three seconds.
If the tank key has been pressed, the left display flashes 1. The right
display then indicates the current setpoint temperature of the reservoir.
NOTE: The setpoint temperatures for grid and reservoir can not be set
separately. However, it is possible in software versions 2.023 and higher
with a temperature offset (operating parameter 29):
Setpoint Reservoir + Temperature offset = Setpoint Grid
Example: 150 _C + (−15 _C) = 135 _C
If a hose or gun key has been pressed, the left display flashes the
number of the first sequential hose or gun. The right display then
indicates the current setpoint temperature of the component shown in
the left display.
2. Scroll the left display to the number of the desired component.
The right display then indicates the current setpoint temperature of the
component selected in the left display.
3. Press the Enter key.
The right display flashes.
4. Use the keypad to enter the setpoint temperature recommended by the
material manufacturer.
NOTE: If the keypad or the right display scroll keys have no effect on
the right display, the melter is protected by a password. Enter a valid
password before changing the setpoint temperatures. Refer to Entering
Password in this section.
5. If additional setpoint temperatures are to be changed, press Enter to
confirm and then select the next component.
6. Press any component key (tank, hose or gun) to return to normal mode.
The selected component begins to heat or cool to the new setpoint
temperature.
Switching Off Component
A setpoint temperature of zero degrees (Celsius or Fahrenheit) turns the
component off.
