Cleaning: Clean gently the front panel and keys of this instrument with
a soft moistened cloth (not too wet). Do not use a dry cloth
for cleaning the LCD display for risk of static electricity. (If
the LCD is accidently charged by static electricity, the LCD
will turn back to normal for several minutes.) Do not use
organic solvents such as alcohol.
Overhaul: To maintain reliable operation for a long time, we
recommend an overhaul after two or three years. If the need
of overhaul arises, contact the dealer or your nearest
CHINO office.
See the following table for the obvious consumable parts used in the
instrument. Generally, most of the parts are subject to change or
degradation over time.
Part name Expected life
Relay
*For control and event outputs
Approx. 100,000 times
Electrolytic capacitor
*Smoothing capacitor for power
circuit
Approx. 5 years
(Ambient temperature: 30°C,
operation time: 12 hours/day)
When an inappropriate setting or operation is performed, the warning
No. shown below will be displayed for approx. three seconds. Check
the warning contents and try appropriate setting or operation.
Warning No. Warning contents

Program operation cannot be executed.
Check that the program pattern is set correctly.

Feedback tuning fails or the zero adjustment value
of servo exceeds the span adjustment value. Check
the feedback input line if the connection is done
properly for the OPEN and CLOSE sides.
□
Key lock is active. Set "Key lock (MODEt)" to
"Function OFF". When a parameter is changed
during a writing process via communication, the key
lock becomes active temporarily to restrict the key
operation. To change a parameter by keys, stop the
writing process via communication, and change the
screen once using the [▼SEL] or [▲SEL] key.
When an error occurs in the system, the error No. shown below will be
displayed for approx. two seconds. Check the error contents and contact
the dealer or your nearest CHINO office.
