Initial Operation
# Caution:
Initial operation is only possible if the operating voltage is switched on and the housing is
open. Therefore, only persons that have been instructed in the danger of electricity, based on
the rules for the prevention of accidents, are authorized to perform initial operation.
Once the initial operation has been carried out, the master terminal is ready for operation. The
readiness for operation is indicated by the LEDs on the MPU board (see chapter "MPU Board") and
the date, time of LCD display.
Initial operation comprises the following steps:
1. Erasure and initialization of the RAM via cold boot.
2. Configuration of the network interface via PC with RS 232 or TELNET from a remove network PC
if the network addresses are identical. Detailed information on PC RS 232 connection can be
found in the chapter Service PC Connection. The program (OC task menu) for the configuration
is part of the controller software and can only be operated if the password entered corresponds to
the password saved.
3. Setting of the display contrast.
Each of these steps are to be carried out in this order after the mounting and the cable laying have
taken place. Details on the procedure are described in the following chapters.
