1.3. Test functions
Digital Inputs 5 - 8, 13 -16
These digits refer to the digital inputs of the control. To test the digital inputs, apply 24V to the
inputs and check if they change to '1'.
Digital Outputs 1-4, 9-12, 17-24
These digits refer to the digital outputs of the control. To change an output, move the cursor to
the required output number and press ENTER.
Analog
Column with several analog I/O signals, inputs and outputs.
The analog output voltages can be set between -10V and 10V with the left and right arrow
keys or by typing a DA-value. These are 12-bit values between -4095 and 4095. The offset
voltage can be programmed in the same manner.
The analog inputs accept voltages between -10V and 10V. The voltage is indicated with 12-bit
values between -4095 and 4095.
Encoder
Test the encoder input and the encoder counting. Use the ‘Ref’ field to check the encoder
reference signal. When switched on, the input will accept a reference pulse from the encoder.
When switched off, the input will ignore any reference pulse.
1.4. Service screens
The control status and I/O behaviour can also be monitored in the operation modes. In these
modes, several service screens can be activated. The service screens are available in
Automatic mode and Manual mode.
There are three service screens:
• control status
• signal status
• I/O status
When the control is stopped, a service screen is opened by pressing the Stop key
continuously. When the control is started, a service screen is opened by pressing the Start
key continuously.
The service screen appears.
