6 Troubleshooting

6.1 Overview

This section describes typical FlexTRAK-OH process alarm conditions that can occur during system

operation and provides troubleshooting tips for their correction.

This section contains the following topics:

• Alarm and Recovery

6.2 Safety First

Operation of your FlexTRAK-OH Material Handler involves mechanical devices, air pressure, and

electrical power. It is essential that every person servicing or operating the FlexTRAK-OH fully

understands all hazards, risks, and safety precautions. When properly operated and maintained, the

FlexTRAK-OH Material Handler should be safe and reliable. Refer to Section 2 - Safety prior to

troubleshooting

6.3 Alarm and Recovery

6.3.1 Main Alarm Error Messages

Table 6-1 Main Alarm Error Messages

No. Alarm Message Cause Recovery

1 Guard door open

Sliding door sensor

a) Close all sliding doors (both the slide door sensor and

switch are in contact range).

b) Check sensor and switch is present. Ensure the

orientation and location is correct.

c) Check sensor condition by observing the physical

damage and IO indicator status.

RESET button

Press RESET button twice to acknowledge the alarm and

allow the process to restart.

Safety relay Check device condition.

Immediate stop

button is pressed

Faulty part under

monitoring

Check and rectify occurred problem or jammed part.

RESET button

Press RESET button to acknowledge the message and

continue paused production process sequences.

Main air pressure is

low

Main incoming air

line

a) Check main air supplied valve is available (compressor is

running).

b) Ensure isolation valve is open.

Air service unit

a) Ensure isolation knob is open/fully open.

b) Ensure pressure sensor value shown with the required

pressure level.

c) Ensure the soft-start valve is operated normally (wiring

socket is connected).

d) Ensure no contamination (dust, rust, tear and wear, etc.)

are present along with the air preparation unit.

Air tubing

Ensure no air leak or air tubing is critically kink along with

the affected tubing tag.

Main safety not

ready

EMO button Released all pressed EMO button.

RESET button

Press RESET button twice to acknowledge alarm and allow

the process to restart.

Safety relay Check device condition.

Plasma machine not

ready

Plasma unit

Check and rectify error code triggered by the plasma unit at

the plasma HMI screen.

6 PLC error PLC CPU unit

a) Check the error code triggered by the PLC CPU unit

display.

b) Check the CPU model number.

c) Refer to the PLC CPU unit manufacturer manual for

further recovery steps.

Untreated magazine

loading: overhead

conveyor

a) Identify overhead conveyor at the magazine

loading area.

b) Ensure magazine is loaded and conveyor is

moving magazine until reach magazine present

sensor.

Conveyor assembly

functionality

a) Ensure conveyor move smoothly.

b) Check any slacking belt if the conveyor

movement is abnormal.

c) Check for motor overheating systems due to

overload or efficiency defects.

Sensor

a) The sensor should trigger output when it

detects the object under its sensing area.

b) Check the sensor sensing area, location,

orientation, and gap distance for any inaccurate

alignment issues.

c) Check the sensor surface for any foreign debris

or liquid, or damage.

d) Check voltage or amperage status along the

wire to the related sensor.

e) If power is supplied, check the sensor output

signal by placing a metal surface close to the

sensing surface.

f) If power is supplied, but no output signal from

the sensor, contact March for assistance.

g) If no power is supplied, contact March for

assistance.

40, 50

Jammed magazine or

strip

a) Identify any jammed parts.

b) Ensure the required magazine is loaded

smoothly.

c) Ensure the magazine position inside the gripper

is firm.

Jammed part

a) The sensor should trigger output when it

detects the object under its sensing area.

b) Example of jammed parts: pneumatic cylinder

rod position extends or retracts.

c) If the cylinder does not successfully

extend/retract to its designated position, the

flag will not trigger the sensor output when

required by the PLC logic. This will trigger a

sensor TIME OUT! error when the affected

sensor response time ends.

d) Identify any jammed/loosen mechanisms that

cause the cylinder rod positioning fault. Clear or

rectify the faulty area.
