This chapter describes how to maintain the E1000 operator panel hardware. The
chapter includes general information, hardware tests and certificates, technical data,
a hardware replacement guide, and a fault tracing section.
3.1 General Information about Hardware
Before the operator panels are approved for market introduction, they are tested by
independent authorities. The E1000 operator panels are examined by several author-
ities before being approved for market introduction. All operator panels are designed
to fulfill CE, UL, and other standards. The quality policy and environmental policy
place demands on all suppliers and subcontractors.
3.2 Hardware Tests
The manufacturer performs extensive hardware testing before an operator panel is
approved. Some tests are performed by external testing companies, such as the
Swedish National Testing and Research Institute.
All operator panels are submitted to testing before leaving the manufacturer.
