Explanation And Function Of Each Signal Light In The Electronic Control Box Of The PU Projectile Loom Due To Malfunction
PU gripper loom, origin: Switzerland, brand:SULZER. Our company has collected the instructions and functions of various signal lights on the electronic control box of the PU gripper loom for fault diagnosis and maintenance.
1. The flashing blue light indicates a broken warp yarn;
2. The flashing yellow light indicates that the weft yarn is broken or stopped using the stop button;
3. Flashing yellow and red lights means using the emergency stop button to stop the vehicle;
4. When the yellow light is on, it indicates that the fabric has reached the predetermined length;
5. The flashing red light indicates a running fault (reminding the maintenance personnel to repair);
6. When the gripper loom is running, the flashing red light indicates that the PFR module switches to the "OP" position (electronic shuttle failure) or the SFW module switches to the "LS" position (weft detector failure). In addition to the signal light, the LED on the LAL module located in the main control box can also indicate the cause of the machine stop.
The abbreviations next to light-emitting diodes have the following meanings:
MEC=Mechanical Failure
EGS=Electronic control refueling system malfunction
KSA=let-off transmission device * motor failure
MOT=Thermal relay overload of transmission motor
PFR=Early Projectile arrival recognition signal (electronic shuttle detector)
KSV=fuse * overload
WIS=Response of Angle Sensor to Brake Drum Wear and Erosion
VDR=fully twisted leno device * malfunction
KFR=Broken warp yarn on the right-hand side of the loom
KFL=Broken warp yarn on the left-hand side of the loom
AUS=Stop with stop button
NOT=Stop with emergency stop button
SFW=Weft yarn breakage
STZ=Stop the machine after reaching the predetermined fabric length (only effective when the rocker switch is in the "STOP" position)
*Not all looms have it
**The accurate shutdown reason is indicated by the PFR module:
FLT=Defective flight trigger
TSN=The sensor at the shuttle receiving device is faulty
KPF=The shuttle does not reach the receiving device or bounces out
PZS=Late Projectile
Instructions for the electric control box, Projectile Loom malfunction, and important instructions for the shuttle signal light:
The rocker switch on the PFR module in the switch box was originally located in the "lower" position. If the switch is set to "OP", the electronic shuttle inspection device will fail. This is indicated by the red signal light flashing when the loom is rotating. The "OP" position is only used for trial running when the loom is free of shuttles.
The above description of the electronic control box indicates that the Projectile Loom is malfunctioning. The abbreviation for the Projectile Loom signal light is provided for the maintenance personnel of the Projectile Loom to diagnose and repair PU type looms in a timely manner. Welcome everyone to exchange and learn.
