OI PT 1300 D English / Edition 3.0 / 23.10.2009
4.5 ERROR MESSAGE
4.5.1 DRIVE OVERLOAD
The maximum rotational speed depends on the size of the dispersing aggregate, the type
of product and viscosity. With deviations from the programmed rotational speed, e.g. by
means of a strong rise in viscosity, the digital display will flash alternately between the
speed and the message "OL", which means that the preset rotational speed will not be
reached any longer. Once the device reaches the speed the message "OL" disappears.
This message cannot be acknowledged.
4.5.2 THERMAL OVERLOAD PROTECTION
If the heat sink temperature of the motor rises above 80°C, the internally installed thermal
idicator interrupts the output current circuit. On the display appears the message “HOT”
and you can hear an acoustic signal. To acknowledge the fault, you have to set OFF the
main switch. The operating module continues to function, the motor, however is no longer
driven until the heat sink has cooled down to below 50°C. The unit must be restarted after
that.
4.5.3 BLOCKING PROTECTION
Is the aggregate blocked for example to a solid material, the output current circuit
interrupts. On the display appears the message “BLC” and you can hear an acoustic
signal. To acknowledge the fault, you have to set OFF the main switch. Removing the solid
from the aggregate. The unit must be restarted after that.
4.5.4 HALLSENSOR
The motor is equipped with 3 Hallsensors. The function of the hallsensors is to detect the
speed of the motor. Is a hallsensor defective, on the display appears the message “HAL”
and you can hear an acoustic signal. To acknowledge the fault, you have to set OFF the
main switch. The unit must be restarted after that.
If the fault can not be resetted the unit must be sended to KINEMATICA AG for repair.
4.5.5 INTERFACE
The hardware from the PT 1300 D is equipped by default with two Interfaces. USB
interface with a standard type B connector and an RS232 interface with a 9 pin D-sub
connector.The standard protocol is MODBUS. Interface could be controlled and regulated
via PC. Profiles with rpm defaults could be fully automated.
More details about the MODBUS control you can find in the appendix 11.
