5-2-6 System Errors
When errors occur in the CS1-CPU Unit or on the I/O Bus the ERH-LED is turned
ON. At the occurrence of an I/O Bus error an error code (see n+17, n+18) is gen-
erated as well.
Clearing System errors Turn ON the power supply again or restart the system. If the error persists then
replace the CS1-CPU.
5-3 Maintenance and Inspection
This section describes the routine cleaning and inspection recommended as reg-
ular maintenance.
5-3-1 Cleaning
Clean the High-speed Counter Unit regularly as described below in order to keep
it in its optimal operating condition.
•
Wipe the Unit with a dry, soft cloth for regular cleaning.
•
When a spot cannot be removed with a dry cloth, dampen the cloth with a neu-
tral cleanser, wring out the cloth, and wipe the Unit.
•
A smudge may retain on the Unit from gum, vinyl, or tape that was left on for a
long time. Remove the smudge when cleaning.
!Caution
Never use volatile solvents such as paint thinner or benzene or chemical wipes.
These substances could damage the surface of the Unit.
5-3-2 Routine Inspections
In order for your High-speed Counter Unit to continue operating at optimum con-
dition, periodic inspections are necessary. Be sure to inspect the system periodi-
cally to keep it in its optimal operating condition. In general, inspect the system
once every 6 to 12 months, but inspect more frequently if the system is used with
high temperature or humidity or under dirty / dusty conditions.
