13.5.4 The Individual DIP Switches Signify the Following:
Switches Off
On
1
Channel 1: normal operation
Channel 1: test operation
2
Channel 1: 0 V to 10 V
(in test operation)
Channel 1: 0mA to 20mA
(in test operation)
3
Channel 2: normal operation
Channel 2: test operation
4
Channel 2: 0 V to 10 V
(in test operation)
Channel 2: 0mA to 20mA
(in test operation)
In test operation, DIP switches 5 to 8 indicate the analog value output as a percentage.
Switches
Meaning in Test Operation
5
10% of the analog end value (in test operation, for both channels)
6
20% of the analog end value (in test operation, for both channels)
7
30% of the analog end value (in test operation, for both channels)
8
40% of the analog end value (in test operation, for both channels)
The analog output value and mode of operation should be set first. Only after this should
the DIP switch be set to test operation. The output value for this channel will then be
saved and output. In this way, it is possible to assign an individual output value to each
channel. Changes to the operating mode and value output will be discarded until the
normal/test switch is set to test operation.
LEDs 1 and 2 display the analog value of the respective output channels. For this purpose,
the LEDs are controlled by flashing. The speed of the flashes shows the analog output
value. The flash rhythm is divided into 20% stages. If the LED is on for 20% of the time,
the output value is < 20%. If the LED is on continuously, the output value is > 80%.
In between, the time during which the LED is on is increased in 20% increments.
LED 3 is switched on if output 1 is in test operation. LED 4 indicates the test operation
of channel 2.
