Table 3: LS-14 Troubleshooting (Continued)

Issues

Possible Causes

Solutions

The regulator is leaking.

The poppet assembly may need to be
replaced.

Check the poppet assembly and the seat
on the regulator. Replace as necessary.
Refer to the

Installation, Operation, and

Maintenance

(IOM)

Manual

for the

regulator for instructions on maintaining
the regulator.

The mixer is not working properly.

The pneumatic supply may be too high,
too low, or not operating.

The hydraulic supply may be too low or
not operating.

The relief and check valve in the
hydraulic line have failed.

Inspect the pneumatic supply and
regulator to ensure that air is supplied at
the appropriate pressure.

Inspect the electro-hydraulic unit (EHUC).
Add hydraulic oil as necessary. Ensure that
hydraulics is supplied at the appropriate
pressure. If the EHUC is not operating,
refer to the

Installation, Operation, and

Maintenance

(IOM)

Manual

for the EHUC.

Maintain the relief and check valve. Refer
to the

Installation, Operation, and

Maintenance
