connections.
No air supply
Supply 140kPa
(1.4kgf/cm[2])
Pilot relay is faulty.
Inspect and/or replace
pilot relay.
Output is
unstable.
Large fluctuation in air supply
pressure
Ensure air supply
pressure is constant.
The pressure leakage (volume) on
the output circuit side is fluctuating.
Check for pressure leaks.
Pilot relay is faulty.
Inspect and/or replace
pilot relay.
Large output
error
Zero and span settings are out of
adjustment.
Re-adjust zero and span
settings.
