10.3 Test position feedback (TPF)
Description
You can carry out the "Cold starting" function test using the "Test Position
Feedback (TPF)" function block. For this purpose, the function block input
(plug) must be connected to the respective socket. The activated test
position will be indicated by the flashing QL of the control function.
The "Test Position Feedback (TPF)" function block consists of:
• One plug
• One "Status - Test position" socket.
This is set when a signal is pending at the input.
• One "Trip - Test position feedback" socket.
This is set when:
– "TPF" is activated although current is flowing in the main circuit
– "TPF" is activated and current is flowing in the main circuit.
Overall, there is one "Test Position Feedback" function block for BU1 and
BU2.
Note
When the test position is enabled, the QLE/QLA sockets of the control
function are activated, to indicate test operation of the motor feeder via a
blinking button LED, for example.
