Risk of uncontrolled movements when switching on the system!
There is a danger of personal injury if the system is in an undefined state.
1. Put the system in a safe state before switching it on.
2. Make sure that no personnel are within the hazardous zone when the com-
pressed air supply is switched on.
1. Switch on the operating voltage.
The controller sends parameters and configuration data to the bus coupler,
electronic components in the valve zone, and I/O modules during startup.
2. After the initialization phase, check the LED statuses on all modules (see "LED
Diagnosis on the Bus Coupler") and system description of the I/O modules.
Before applying the working pressure, the diagnostic LEDs may only be illumi-
nated in green, as described in Table 12:

At least one of the two LEDs L/A 1 and L/A 2 must be illuminated or flashing in
green.
If the diagnostic run is successful, you may commission the valve system. Other-
wise, the errors must be remedied (see "Troubleshooting").
Switch on the compressed air supply.

11 LED Diagnosis on the Bus Coupler

The bus coupler monitors the power supplies for the electronic components and
actuator control. If they exceed or fall below a set threshold, an error signal will
be generated and reported to the controller. In addition, the status is displayed
by the diagnostic LEDs.

Reading the diagnostic display on the bus coupler

The LEDs on the top of the bus coupler report the messages listed in Table 13.
Before commissioning and during operation, regularly check the bus coupler
u
functions by reading the LEDs.

12 Conversion of the Valve System

Danger of explosion caused by defective valve system in an explosive atmos-
phere!
Malfunctions may occur after the configuration or conversion of the valve sys-
tem.
After configuring or converting a system, always perform a function test in
u
a non-explosive atmosphere before recommissioning.
This chapter describes the structure of the complete valve system, the rules for
converting the valve system, the documentation of the conversion, as well as the
re-configuration of the valve system.
