MELTER OPERATION
Minimum rpm alarm
This alarm will be triggered when the motor rotates at a speed that is below
the MINIMUM RPM ALARM for the period established in the MINIMUM RPM
ALARM TIME field.
• When this alarm is triggered, an ‘E.L.’ error is shown on the control
card.
• To reset this error, you must turn off and start up the control card with
its ON/OFF button.
Variator alarm
This alarm is triggered when the control card input is activated by a variator
error signal.
• When this alarm is triggered, an ‘E.U.’ error is shown on the control
card.
• The error message will be maintained while the variator error input
(E5) remains active. As soon as this input is deactivated the alarm will
be reset.
Note: In the event that a RPM alarm and a variator ERROR alarm should
coincide, alternating messages will appear on the display.
Configuring speed ramp
For equipment operating in external reference, the display will show the
current pump rotation set point (input reference conversion as per the full
scale and the conversion table).
The conversion table may be programmed with up to 5 points (input voltage (V)
and output speed (RPM)).
By default the table is programmed (0 V = 0 rpm and 10 V = 100 rpm):
