Sensor installation & wiring is going on.

Replaced the shade. Repaired the burnt shade with new wiring. Solved

Solved

Wash the head & adjust the sensor & head. Ok.

Checked coil & valve, cleaned plunger. Solved

Dismantle the motor,checked coil & found ok. Changed the seal, heated the armature & refited. No load current-3.1,3.1,3.2 (Rated current-5.5A)

This comp. is not in service now.

There is leakage inside the anton paar CO2 measuring module. Changed 3 pcs diaphragms.

Checked & changed defective auxiliary contact. Rated current-2.8A, Running current-2.2APrepared one new Control box.Installed new cable tray, control panel & connected the motor with control panel.

Adjust the sensor & bring a new optical fiber photo sensor adapter for high speed printing at L4.

Dismantle caustic dosing pump, pipe line & clean the caustic solution drum by hot water. After cleaning the whole dosing system dosing has been run automatically. Connect the agitator motor.

Tried to stable the re-boiler by changing some PID value of Lean MEA & rich MEA pump but no improvement.

Need to consult with expert.

Checked the motor & control circuit. Magnetic contactor sizzed. Made it free & run the motor.Installed the pump, Checked & connected the motor. Insulation resistance-200Mohm(p-p), 100Mohm(p-b).

Replaced the motor. Dismantle the motor,checked coil & found ok. Changed the seal, heated the armature, refited.

solved

Checked & temperory manage to run the chiller.

Installed the old panel A/C into shrink wrapper machine. Ok.After servicing, handed over the auto clave to QC department. Ok.

Now it is running

Installed 2 nos. metal halide lamp at shrink film plant. Complete

Now old one is running.

Need to call expert.

replaced the toggle switch. Ok.

Again connect the new pump. Under observation

MPCB was under rated. Replaced the defective MPCB. Ok.

Ok.

Continue..

Adjust the sensor & increase the time in timer. solved

Third party checheked for leakage. Continue..

solved

Ok.

solved

Charged refregerant as they found no leakage. Now it is running. Under observation

Checked all control circuit, communication cable & found a fuse burnt inside optical communication module. Changed the burnt fuse.

Solved. Now machine is running.

Expert checked the machine, changed the motherboard but found no improvement. Now the machine is running on "Auto Refresh" mode. Printing is done by Imaje 9030.

This machine is under maintenance.

Heater is checked by connecting 2 pin power socket. Coil is ok but found water leakage with heater connection.

Need to purchase a new sensor

Took apart the ADT and checked for leakage but ok. Reset the ADT & run the comp.Expert again checked the machine and suggested to changed the ink tank.

This machine is now running.

Disconnected the new pump and set back the pressure switch connection to old pump.

Contact with imaje expert and carried out the suggested procedure several times. But no improvement.

Checked all AC & tried to repair one today. Changed compressor, refregerant gas.Wirinig and sensor installation completed. But could not connect emergency switch connection as line was running.

Checked control circuit & found burnt temperature controller in one machine. Trying to service this controller. Other machine has control card problem (could not get nutral connection). Trying to solve this problem.

A new Imaje 9030 date code machine has been installed for high speed printing at L-4.

Supply pressure reduced to 1-1.5 bar due air problem at sucktion line. Made the pump air free. Motor rated current 10A, now running current 5.5A & pressure 6 bar

Checked all control circuit but could not possible to run the machine correctly. This machine can be modified by using a temperature controller & solied state relay to control the temperature.

Other two are heating now.

tripped due to pump side jamming. Mechanical servicing carried out. Now the motor takes normal running current.

First changed the power cable. But after few hours heater burnt. Need to find the problem during CIP. Now it heated by other two coil.

Repaired leakage of AC-5, vaccumed & charged refregernt gas. Also charged refregerent gas into AC-3.

Modification work going on.One of the circuit is replaced by temperature controller, magnetic contactor & a thermocouple.

Need to checked by expert

Take out the heater box, Checked coil resistance & found 23ohms at both coil. But insulation resistance differ. So, refited the good one. Another coil was kept at tools room as it sparked.

Need to find out the cause during CIP.

Cleaned the head & kept it as stand by. ok

Repaired one machine & sent it to QC lab for their observation. Under observationOverload relay found faulty. Changed the overload relay. solved

Installed one more relay & reset switch & completed wiring.

Give direct connection as new switch was not available.

Carried out cable dressing at raw syrup room. okChecked & found problem in float switch. Servicing carried out. ok.Reset the drive. okReplaced the power socket with a breaker. okSolved the leakage problem of FSR A/C-2. ok

As production started, so ran it manualy.

Checked & found the coil burnt.

AC tripped due to air block. Clean the AC carefully. ok

Replaced 3 core wire by 4 core for DC nutral. ok

Checked and found that charging card still faulty. Need to repair.

Continue..

Replaced the coil. solved

ok

Sent back the hired machine. ok

Checked & found loose contact of the level sensor. ok

Checked by third party. Didn’t find out the problem. Not solvedClean the panel, checked & tightened all the connection ok

Rewinding completed, varnished the coil, Checked coil resistance & found 2.3ohms from each coil. Assambled & ran the motor. Motor vibrate & made abnormal sound.

Need to contact with rewinding party.

Need CIP to adjust the sensorNeed to change the switch

Need to find out the cause during CIP.Need to install another fan

Prepared the controller for installation. It t will be installed during CIP.
