Indicators and Operating Elements
2.3.1
LED Indicators
Overview
The LEDs on the ZPA motor control module display the following information:
■
Firmware version (only immediately after switching on),
■
Setting of the rotary switch (only immediately after switching on),
■
Status of the power supply,
■
Switching states of the connected zone sensors,
■
Operating/fault state of the connected DC roller motors,
■
States of the zone coupling signals.
While the ZPA motor control module is starting up, the LEDs indicate the firmware version and
the setting of the rotary switches using flash codes (binary code; least significant byte is on the
right).
The meaning of the individual zone coupling signals depends on the conveyor direction and
how the ZPA motor control module is connected. (See Chapter "Use and Application", Section
"Zone Coupling").
Figure 2.12
LED Behavior after Switch-On
In case of an invalid configuration or an invalid operating mode, the four left LEDs X1 ...X2 OUT
will flash simultaneously.
While the ZPA motor control module is starting up, the LEDs indicate the firmware version and
the setting of the rotary switches S1 ... S3 in four steps using flash codes. The LEDs provide
the information in binary form. The least significant byte is on the right.
The two left LEDs X1 IN and X1 OUT indicate the respective step from 0 ... 3. The steps
designate the type of information.
The remaining LEDs indicate the corresponding values for the steps, such as the setting of a
rotary switch.
Each step is displayed for 1 s. After 4 s, all the steps have been displayed.
