MELTER OPERATION
At this moment, the pump will start to rotate at the speed indicated on the
display.
4. Adjust the rotation speed to the value required for the application. The
selected value is set pressing the right arrow key after blinking three
times.
The pump will stop whenever:
• The control card is disabled with its ON/OFF button.
• The pumping ON-OFF button is pressed (red LED is illuminated).
• When the pumping permission input is deactivated (E3).
• When a variator error signal is activated (E5).
• When the MAXIMUM RPM ALARM TIME appears.
• When the MINIMUM RPM ALARM TIME appears.
The maximum full scale for admissible revolutions is 100 (we recommend
working at speeds of not less than 10 rpm and not greater than 80 rpm).
The full scale can be adjusted by reducing this value in percentage terms. To
make adjustments consult the ‘User configuration menu’, ‘1. MAXIMUM RPM’.
Mode of operation with external pumping control and external speed
control
In this working mode, both pumping and speed are controlled from the main
machine.
Follow the steps below to use this operating mode:
1. Press the ON/OFF button to light up the control card.
2. Select ‘ok’ in the position ‘ext’ and ‘ref’ in the position ‘ext’. The ‘on
ext’ and ‘ref ext’ LEDs will be illuminated when temperature is ok and
voltage is received.
To activate the start-up status, all of the following conditions must be met:
• That the signal from the main machine reaches input E2 and its value
is not 0.
• That the input for pumping permission (E4) at central control is activated, as
pumping is not possible unless the equipment temperature is OK.
• That pumping is enabled with the pumping ON-OFF button (red LED is
turned off).
• If the external ‘ok’ mode (start-stop) is selected, the external ‘ok’ input
(E3) must be activated.
• That the field MAXIMUM RPM is not set to zero (this field is available on
the control card ‘User configuration menu’).
