Chapter 7 Troubleshooting
This chapter explains equipment trouble and how to remedy it.
When trouble is detected by one of the self-check features, the trouble is
displayed on the instrumentation panel display and a trouble buzzer is sounded.
For trouble undetected in self-checks and misoperation which can be easily
mistaken as trouble, see "7.2 Other Troubles".
This chapter also includes trouble information for options.
7.1 Detectable Troubles
DANGER
•
ELECTRIC SHOCK! Before working on the power
circuits, unplug the primary power supply and
check the line is dead. Also, take measures to
prevent accidental charging.
Working with primary power supply ON runs the risk of electric
shock.
•
Unplug the chamber BEFORE detaching the electric
parts compartment door.
Temperature (and humidity) cabinets are equipped with a buzzer that sounds
when detects trouble as well as self-check features which display the trouble on
the instrumentation panel display. Displayed alarm codes and their content are
given in the alarm table on the following pages. Remedy trouble as described
therein.
For trouble which is undetected in self-checks, see "7.2 Other Troubles". If the
trouble cannot be remedied after taking the prescribed action, contact the place
of purchase or ESPEC. (Call for service.)
1st and 2nd Degree Alarms
Detectable trouble is manifested either as 1st or 2nd degree alarms. They are
defined as follows.
1st degree alarm

control is NOT automatically restored. The trouble state must be cleared in
accordance with the displayed alarm code and the system restarted.
2nd degree alarm
: As soon as the cause of the trouble has been eliminated,
control is automatically restored. However, the alarm code will be displayed
indefinitely until one of the keys is pressed.
