INTRODUCTION

The ETM system with plaintext display provides continuous moni-
toring of all Excavator functions and operating conditions.
The ETM has the capability to cover a total amount of 60 different
messages, the text messages can be selected in English or Ger-
man language.
Further features of the ETM System
The ETM system is equipped with a PROTOCOL Memory for
recording of the fault messages and a STATISTICS Memory
for registration of duration and frequency of each single fault
that has occurred.
Up to 1300 messages can be stored in the record memory
and registered in the statistics memory.
The ETM works in the last (most important) message mode.
The messages are divided into four groups according to their
importance. The last message received by the ETM will be
displayed. If there are several messages at the same time,
the most important message will be displayed. The other
messages are kept in the background. They are indicated by
a flashing number on the screen and can be called up.
Recording of the messages is accomplished with "COMING-
GOING" registration.
The statistics memory counts the frequency of COMING mes-
sages and establishes their total amount.
The Messages are divided into two Main Groups as follows:
1. FAULT MESSAGES
Fault messages indicate a trouble condition, e.g.
Low idle: High pressure filter 1 restricted.
REMARK
Serious faults resulting in an automatic engine shut down,
refer to Fault- and Message list on page 116 for details.
2. INFORMATION MESSAGES
An information message indicates an operating condition,
e.g.
# Caution: Slew gear brake on.
