Melter
(contd.)
Assigning New CAN Bus Sensor
The first two lines are intended for two pressure sensors of pump 1, lines 3
and 4 for two pressure sensors of pump 2. Melters of the type
VA/VT
are
delivered with only one sensor (A) per pump.
NOTE:
Pressure sensor A is usually located at the melter outlet, behind the
filter cartridge. With the option
Pressure display and pressure control
, it
transmits the values to the IPC.
1. Select
of the desired line, then switch the pressure sensor
ON
.
The pressure sensor can be switched on and off. If a pressure sensor is
switched off, it is removed from the assigned location and is available as
a
New sensor
after a short time.
CAUTION:
Do not switch off the melter during assignment as long as the
ON/OFF key appears subdued. This would interrupt the internal
parameterization process, and the pressure sensor would not be
detected later.
2. Wait until the keys are no longer subdued.
3. Check the color of the indication lamp:
Green : Pressure sensor is assigned
Red
: Pressure sensor is defective
CAN bus to sensor is interrupted
CAN bus is faulty
Gray
: No pressure sensor
4. Repeat steps for every new pressure sensor until all have been assigned.
Calibrating Pressure Sensor
NOTE:
To calibrate the sensor, the melter must be heated to processing
temperature and may not be pressurized (relieve pressure if necessary; refer
to section
Installation
).
Calibrate
Perform nullification. Nullification should be performed even if 0 bar
is displayed as the actual value; internal calibration is more precise.
