iQ Pneumatic Press Error Messages

Error Message Description Cause(s) Possible Solution(s)

Overload (average) at

xxx msecs. Power above

generator rating.

Power from ultrasonic stack sent to the

part exceeds power rating of generator.

1. Excessive pressure applied to the part.

2. Booster size is too large.

1. Decrease pressure applied to part.

2. Reduce size of booster.

Overload (peak) at xxx

msecs. Check stack.

1. Component failure in the stack.

2. Improper stack assembly.

3. Incorrect Advanced Hardware settings.

1. Check functionality of stack components.

2. Disassemble and reassemble stack.

3. Check the generator's Advanced Hardware

settings.

Over temperature fault! Generator's internal temperature ex-

ceeds 158º F (70º Celsius).

1. Welder duty cycle is too large.

2. Weld/hold times or forces are too

large.

3. Thruster fan not working.

4. Servo actuator or amplier is dam-

aged.

1. Reduce cycle rate.

2. Change setup to reduce weld/hold forces or

decrease weld duration.

3. Check if fan is obstructed; contact DUKANE

service for replacement.

4. Contact DUKANE service.

Overload (frequency) at

xxx msecs. Check stack,

cable or validate ramp up

time.

Generator is unable to lock to the reso-

nant frequency of the ultrasonic stack.

1. Improper stack assembly.

2. Defective ultrasound cable.

3. Ramp up time is too short.

1. Disassemble and reassemble stack.

2. Replace ultrasound cable.

3. Increase ramp up time.

Overload (frequency) at

xxx msecs. Check for

coupling between stack

and part.

Generator correctly locks to the resonant

frequency of the ultrasonic stack, but

loses the lock at a point later in the weld

cycle.

Horn comes in contact with the part nest

or anvil.

Make adjustments to thruster and part nest.

Power fault. Check AC line. AC line voltage drops below 190 VAC on

240 VAC systems, and below 95 VAC on

120 VAC systems.

Fluctuations in AC power. Check the incoming AC line power.
